1. Albert Einstein: The Whole Package

Albert Einstein was not only a scientific genius but also a figure of enduring popularity and intrigue. His remarkable contributions to science, which include the famous equation E = mc2 and the theory of relativity , challenged conventional notions and reshaped our understanding of the universe.

Born in Ulm, Germany, in 1879, Einstein was a precocious child. As a teenager, he wrote a paper on magnetic fields. (Einstein never actually failed math, contrary to popular lore.) His career trajectory began as a clerk in the Swiss Patent Office in 1905, where he published his four groundbreaking papers, including his famous equation, E = mc2, which described the relationship between matter and energy.

Contributions

Einstein's watershed year of 1905 marked the publication of his most important papers, addressing topics such as Brownian motion , the photoelectric effect and special relativity. His work in special relativity introduced the idea that space and time are interwoven, laying the foundation for modern astronomy. In 1916, he expanded on his theory of relativity with the development of general relativity, proposing that mass distorts the fabric of space and time.

Although Einstein received the Nobel Prize in Physics in 1921, it wasn't for his work on general relativity but rather for his discovery of the photoelectric effect. His contributions to science earned him a prestigious place in the scientific community.

Key Moment 

A crowd barged past dioramas, glass displays, and wide-eyed security guards in the American Museum of Natural History. Screams rang out as some runners fell and were trampled. Upon arriving at a lecture hall, the mob broke down the door.

The date was Jan. 8, 1930, and the New York museum was showing a film about Albert Einstein and his general theory of relativity. Einstein was not present, but 4,500 mostly ticketless people still showed up for the viewing. Museum officials told them “no ticket, no show,” setting the stage for, in the words of the Chicago Tribune , “the first science riot in history.”

Such was Einstein’s popularity. As a publicist might say, he was the whole package: distinctive look (untamed hair, rumpled sweater), witty personality (his quips, such as God not playing dice, would live on) and major scientific cred (his papers upended physics).

Einstein, who died of heart failure in 1955 , left behind a profound legacy in the world of science. His life's work extended beyond scientific discoveries, encompassing his role as a public intellectual, civil rights advocate, and pacifist.

Albert Einstein's theory of general relativity remains one of his most celebrated achievements. It predicted the existence of black holes and gravitational waves, with physicists recently measuring the waves from the collision of two black holes over a billion light-years away. General relativity also underpins the concept of gravitational lensing, enabling astronomers to study distant cosmic objects in unprecedented detail.

“Einstein remains the last, and perhaps only, physicist ever to become a household name,” says James Overduin, a theoretical physicist at Towson University in Maryland.

Einstein's legacy goes beyond his scientific contributions. He is remembered for his imaginative thinking, a quality that led to his greatest insights. His influence as a public figure and his advocacy for civil rights continue to inspire generations.

“I am enough of an artist to draw freely upon my imagination,” he said in a Saturday Evening Post interview. “Knowledge is limited. Imagination encircles the world.”

2. Marie Curie: She Went Her Own Way

Marie Curie's remarkable journey to scientific acclaim was characterized by determination and a thirst for knowledge. Living amidst poverty and political turmoil, her unwavering passion for learning and her contributions to the fields of physics and chemistry have made an everlasting impact on the world of science.

Marie Curie , born as Maria Salomea Sklodowska in 1867 in Warsaw, Poland, faced immense challenges during her early life due to both her gender and her family's financial struggles. Her parents, fervent Polish patriots, sacrificed their wealth in support of their homeland's fight for independence from Russian, Austrian, and Prussian rule. Despite these hardships, Marie's parents, who were educators themselves, instilled a deep love for learning and Polish culture in her.

Marie and her sisters were initially denied higher education opportunities due to societal restrictions and lack of financial resources. In response, Marie and her sister Bronislawa joined a clandestine organization known as the Flying University, aimed at providing Polish education, forbidden under Russian rule.

Marie Curie's path to scientific greatness began when she arrived in Paris in 1891 to pursue higher education. Inspired by the work of French physicist Henri Becquerel, who discovered the emissions of uranium, Marie chose to explore uranium's rays for her Ph.D. thesis. Her research led her to the groundbreaking discovery of radioactivity, revealing that matter could undergo atomic-level transformations.

Marie Curie collaborated with her husband, Pierre Curie, and together they examined uranium-rich minerals, ultimately discovering two new elements, polonium and radium. Their work was published in 1898, and within just five months, they announced the discovery of radium.

In 1903, Marie Curie, Pierre Curie, and Henri Becquerel were jointly awarded the Nobel Prize in Physics for their pioneering work in radioactivity. Marie became the first woman to receive a Nobel Prize, marking a historic achievement.

Tragedy struck in 1906 when Pierre Curie died suddenly in a carriage accident. Despite her grief, Marie Curie persevered and continued her research, taking over Pierre's position at the University of Paris. In 1911, she earned her second Nobel Prize, this time in Chemistry, for her remarkable contributions to the fields of polonium and radium.

Marie Curie's legacy extended beyond her Nobel Prizes. She made significant contributions to the fields of radiology and nuclear physics. She founded the Radium Institute in Paris, which produced its own Nobel laureates, and during World War I, she led France's first military radiology center, becoming the first female medical physicist.

Marie Curie died in 1934 from a type of anemia that likely stemmed from her exposure to such extreme radiation during her career. In fact, her original notes and papers are still so radioactive that they’re kept in lead-lined boxes, and you need protective gear to view them

Marie Curie's legacy endures as one of the greatest scientists of all time. She remains the only person to receive Nobel Prizes in two different scientific fields, a testament to her exceptional contributions to science. Her groundbreaking research in radioactivity revolutionized our understanding of matter and energy, leaving her mark on the fields of physics, chemistry, and medicine.

3. Isaac Newton: The Man Who Defined Science on a Bet

Isaac Newton was an English mathematician, physicist and astronomer who is widely recognized as one of the most influential scientists in history. He made groundbreaking contributions to various fields of science and mathematics and is considered one of the key figures in the scientific revolution of the 17th century.

Isaac Newton was born on Christmas Day in 1642. Despite being a sickly infant, his survival was an achievement in itself. Just 23 years later, with Cambridge University closed due to the plague, Newton embarked on groundbreaking discoveries that would bear his name. He invented calculus, a new form of mathematics, as part of his scientific journey.

Newton's introverted nature led him to withhold his findings for decades. It was only through the persistent efforts of his friend, Edmund Halley, who was famous for discovering comets, that Newton finally agreed to publish. Halley's interest was piqued due to a bet about planetary orbits, and Newton, having already solved the problem, astounded him with his answer.

The culmination of Newton's work was the "Philosophiæ Naturalis Principia Mathematica," commonly known as the Principia , published in 1687. This monumental work not only described the motion of planets and projectiles but also revealed the unifying force of gravity, demonstrating that it governed both heavenly and earthly bodies. Newton's laws became the key to unlocking the universe's mysteries.

Newton's dedication to academia was unwavering. He rarely left his room except to deliver lectures, even if it meant addressing empty rooms. His contributions extended beyond the laws of motion and gravitation to encompass groundbreaking work in optics, color theory, the development of reflecting telescopes bearing his name, and fundamental advancements in mathematics and heat.

In 1692, Newton faced a rare failure and experienced a prolonged nervous breakdown, possibly exacerbated by mercury poisoning from his alchemical experiments. Although he ceased producing scientific work, his influence in the field persisted.

Achievements

Newton spent his remaining three decades modernizing England's economy and pursuing criminals. In 1696, he received a royal appointment as the Warden of the Mint in London. Despite being viewed as a cushy job with a handsome salary, Newton immersed himself in the role. He oversaw the recoinage of English currency, provided economic advice, established the gold standard, and introduced ridged coins that prevented the tampering of precious metals. His dedication extended to pursuing counterfeiters vigorously, even infiltrating London's criminal networks , and witnessing their executions.

Newton's reputation among his peers was marred by his unpleasant demeanor. He had few close friends, never married, and was described as "insidious, ambitious, and excessively covetous of praise, and impatient of contradiction" by Astronomer Royal John Flamsteed. Newton held grudges for extended periods and engaged in famous feuds, notably with German scientist Gottfried Leibniz over the invention of calculus and English scientist Robert Hooke.

Isaac Newton's legacy endures as one of the world's greatest scientists. His contributions to physics, mathematics, and various scientific disciplines shifted human understanding. Newton's laws of motion and gravitation revolutionized the field of physics and continue to be foundational principles.

His work in optics and mathematics laid the groundwork for future scientific advancements. Despite his complex personality, Newton's legacy as a scientific visionary remains unparalleled.

How fitting that the unit of force is named after stubborn, persistent, amazing Newton, himself a force of nature.

4. Charles Darwin: Delivering the Evolutionary Gospel

Charles Darwin has become one of the world's most renowned scientists. His inspiration came from a deep curiosity about beetles and geology, setting him on a transformative path. His theory of evolution through natural selection challenged prevailing beliefs and left an enduring legacy that continues to shape the field of biology and our understanding of life on Earth.

Charles Darwin , an unlikely revolutionary scientist, began his journey with interests in collecting beetles and studying geology. As a young man, he occasionally skipped classes at the University of Edinburgh Medical School to explore the countryside. His path to becoming the father of evolutionary biology took an unexpected turn in 1831 when he received an invitation to join a world-spanning journey aboard the HMS Beagle .

During his five-year voyage aboard the HMS Beagle, Darwin observed and documented geological formations, various habitats and the diverse flora and fauna across the Southern Hemisphere. His observations led to a paradigm-shifting realization that challenged the prevailing Victorian-era theories of animal origins rooted in creationism. 

Darwin noticed subtle variations within the same species based on their environments, exemplified by the unique beak shapes of Galapagos finches adapted to their food sources. This observation gave rise to the concept of natural selection, suggesting that species could change over time due to environmental factors, rather than divine intervention.

Read More: 7 Things You May Not Know About Charles Darwin

Upon his return, Darwin was initially hesitant to publish his evolutionary ideas, instead focusing on studying his voyage samples and producing works on geology, coral reefs and barnacles. He married his first cousin, Emma Wedgwood, and they had ten children, with Darwin actively engaging as a loving and attentive father — an uncommon practice among eminent scientists of his era.

Darwin's unique interests in taxidermy , unusual food and his struggle with ill health did not deter him from his evolutionary pursuits. Over two decades, he meticulously gathered overwhelming evidence in support of evolution.

Publication

All of his observations and musings eventually coalesced into the tour de force that was On the Origin of Species , published in 1859 when Darwin was 50 years old. The 500-page book sold out immediately, and Darwin would go on to produce six editions, each time adding to and refining his arguments.

In non-technical language, the book laid out a simple argument for how the wide array of Earth’s species came to be. It was based on two ideas: that species can change gradually over time, and that all species face difficulties brought on by their surroundings. From these basic observations, it stands to reason that those species best adapted to their environments will survive and those that fall short will die out.

Despite facing fierce criticism from proponents of creationism and the religious establishment, Darwin's theory of natural selection and evolution eventually gained acceptance in the 1930s. His work revolutionized scientific thought and remains largely intact to this day.

His theory, meticulously documented and logically sound, has withstood the test of time and scrutiny. Jerry Coyne, a professor emeritus at the University of Chicago, emphasizes the profound impact of Darwin's theory, stating that it "changed people’s views in so short a time" and that "there’s nothing you can really say to go after the important aspects of Darwin’s theory."

5. Nikola Tesla: Wizard of the Industrial Revolution

Nikola Tesla grips his hat in his hand. He points his cane toward Niagara Falls and beckons bystanders to turn their gaze to the future. This bronze Tesla — a statue on the Canadian side — stands atop an induction motor, the type of engine that drove the first hydroelectric power plant.

Nikola Tesla exhibited a remarkable aptitude for science and invention from an early age. His work in electricity, magnetism and wireless power transmission concepts, established him as an eccentric but brilliant pioneer in the field of electrical engineering.

Nikola Tesla , a Serbian-American engineer, was born in 1856 in what is now Croatia. His pioneering work in the field of electrical engineering laid the foundation for our modern electrified world. Tesla's groundbreaking designs played a crucial role in advancing alternating current (AC) technology during the early days of the electric age, enabling the transmission of electric power over vast distances, ultimately lighting up American homes.

One of Tesla's most significant contributions was the development of the Tesla coil , a high-voltage transformer that had a profound impact on electrical engineering. His innovative techniques allowed for wireless transmission of power, a concept that is still being explored today, particularly in the field of wireless charging, including applications in cell phones.

Tesla's visionary mind led him to propose audacious ideas, including a grand plan involving a system of towers that could harness energy from the environment and transmit both signals and electricity wirelessly around the world. While these ideas were intriguing, they were ultimately deemed impractical and remained unrealized. Tesla also claimed to have invented a "death ray," adding to his mystique.

Read More: What Did Nikola Tesla Do? The Truth Behind the Legend

Tesla's eccentric genius and prolific inventions earned him widespread recognition during his lifetime. He held numerous patents and made significant contributions to the field of electrical engineering. While he did not invent alternating current (AC), he played a pivotal role in its development and promotion. His ceaseless work and inventions made him a household name, a rare feat for scientists in his era.

In recent years, Tesla's legacy has taken on a life of its own, often overshadowing his actual inventions. He has become a symbol of innovation and eccentricity, inspiring events like San Diego Comic-Con, where attendees dress as Tesla. Perhaps most notably, the world's most famous electric car company bears his name, reflecting his ongoing influence on the electrification of transportation.

While Tesla's mystique sometimes veered into the realm of self-promotion and fantastical claims, his genuine contributions to electrical engineering cannot be denied. He may not have caused earthquakes with his inventions or single handedly discovered AC, but his visionary work and impact on the electrification of the world continue to illuminate our lives.

6. Galileo Galilei: Discoverer of the Cosmos

Galileo Galilei , an Italian mathematician, made a pivotal contribution to modern astronomy around December 1609. At the age of 45, he turned a telescope towards the moon and ushered in a new era in the field.

His observations unveiled remarkable discoveries, such as the presence of four large moons orbiting Jupiter and the realization that the Milky Way's faint glow emanated from countless distant stars. Additionally, he identified sunspots on the surface of the sun and observed the phases of Venus, providing conclusive evidence that Venus orbited the sun within Earth's own orbit.

While Galileo didn't invent the telescope and wasn't the first to use one for celestial observations, his work undeniably marked a turning point in the history of science. His groundbreaking findings supported the heliocentric model proposed by Polish astronomer Nicolaus Copernicus, who had revolutionized astronomy with his sun-centered solar system model . 

Beyond his astronomical observations, Galileo made significant contributions to the understanding of motion. He demonstrated that objects dropped simultaneously would hit the ground at the same time, irrespective of their size, illustrating that gravity isn't dependent on an object's mass. His law of inertia also played a critical role in explaining the Earth's rotation.

Galileo's discoveries, particularly his support for the Copernican model of the solar system, brought him into conflict with the Roman Catholic Church. In 1616, an inquisition ordered him to cease promoting heliocentrism, as it contradicted the church's geocentric doctrine based on Aristotle's outdated views of the cosmos.

The situation worsened in 1633 when Galileo published a work comparing the Copernican and Ptolemaic systems, further discrediting the latter. Consequently, the church placed him under house arrest, where he remained until his death in 1642.

Galileo's legacy endured despite the challenges he faced from religious authorities. His observations and pioneering work on celestial bodies and motion laid the foundation for modern astronomy and physics.

His law of inertia, in particular, would influence future scientists, including Sir Isaac Newton, who built upon Galileo's work to formulate a comprehensive set of laws of motion that continue to guide spacecraft navigation across the solar system today. Notably, NASA's Galileo mission to Jupiter, launched centuries later, demonstrated the enduring relevance of Galileo's contributions to the field of space exploration.

7. Ada Lovelace: The Enchantress of Numbers

Ada Lovelace defied the conventions of her era and transformed the world of computer science. She is known as the world's first computer programmer. Her legacy endures, inspiring generations of computer scientists and earning her the title of the "Enchantress of Numbers.”

Ada Lovelace, born Ada Byron, made history as the world's first computer programmer, a remarkable achievement considering she lived a century before the advent of modern computers. Her journey into the world of mathematics and computing began in the early 1830s when she was just 17 years old. 

Ada, the only legitimate child of the poet Lord Byron, entered into a pivotal collaboration with British mathematician, inventor, and engineer Charles Babbage. Babbage had conceived plans for an intricate machine called the Difference Engine — essentially a massive mechanical calculator.

Read More: Meet Ada Lovelace, The First Computer Programmer

At a gathering in the 1830s, Babbage exhibited an incomplete prototype of his Difference Engine. Among the attendees was the young Ada Lovelace, who, despite her age, grasped the workings of the machine. This encounter marked the beginning of a profound working relationship and close friendship between Lovelace and Babbage that endured until her untimely death in 1852 at the age of 36. Inspired by Babbage's innovations, Lovelace recognized the immense potential of his latest concept, the Analytical Engine.

The Analytical Engine was more than a mere calculator. Its intricate mechanisms, coupled with the ability for users to input commands through punch cards, endowed it with the capacity to perform a wide range of mathematical tasks. Lovelace, in fact, went a step further by crafting instructions for solving a complex mathematical problem, effectively creating what many historians later deemed the world's first computer program. In her groundbreaking work, Lovelace laid the foundation for computer programming, defining her legacy as one of the greatest scientists.

Ada Lovelace's contributions to the realm of "poetical science," as she termed it, are celebrated as pioneering achievements in computer programming and mathematics. Despite her tumultuous personal life marked by gambling and scandal, her intellectual brilliance and foresight into the potential of computing machines set her apart. Charles Babbage himself described Lovelace as an "enchantress" who wielded a remarkable influence over the abstract realm of science, a force equivalent to the most brilliant male intellects of her time.

8. Pythagoras: Math's Mystery Man

Pythagoras left an enduring legacy in the world of mathematics that continues to influence the field to this day. While his famous Pythagorean theorem , which relates the sides of a right triangle, is well-known, his broader contributions to mathematics and his belief in the fundamental role of numbers in the universe shaped the foundations of geometry and mathematical thought for centuries to come.

Pythagoras , a Greek philosopher and mathematician, lived in the sixth century B.C. He is credited with the Pythagorean theorem, although the origins of this mathematical concept are debated.

Pythagoras is most famous for the Pythagorean theorem, which relates the lengths of the sides of a right triangle. While he may not have been the first to discover it, he played a significant role in its development. His emphasis on the importance of mathematical concepts laid the foundation for modern geometry.

Pythagoras did not receive formal awards, but his legacy in mathematics and geometry is considered one of the cornerstones of scientific knowledge.

Pythagoras' contributions to mathematics, particularly the Pythagorean theorem, have had a lasting impact on science and education. His emphasis on the importance of mathematical relationships and the certainty of mathematical proofs continues to influence the way we understand the world.

9. Carl Linnaeus: Say His Name(s)

Carl Linnaeus embarked on a mission to improve the chaos of naming living organisms. His innovative system of binomial nomenclature not only simplified the process of scientific communication but also laid the foundation for modern taxonomy, leaving an enduring legacy in the field of biology.

It started in Sweden: a functional, user-friendly innovation that took over the world, bringing order to chaos. No, not an Ikea closet organizer. We’re talking about the binomial nomenclature system , which has given us clarity and a common language, devised by Carl Linnaeus.

Linnaeus, born in southern Sweden in 1707, was an “intensely practical” man, according to Sandra Knapp, a botanist and taxonomist at the Natural History Museum in London. He lived at a time when formal scientific training was scant and there was no system for referring to living things. Plants and animals had common names, which varied from one location and language to the next, and scientific “phrase names,” cumbersome Latin descriptions that could run several paragraphs.ccjhhg

While Linnaeus is often hailed as the father of taxonomy, his primary focus was on naming rather than organizing living organisms into evolutionary hierarchies. The task of ordering species would come later, notably with the work of Charles Darwin in the following century. Despite advancements in our understanding of evolution and the impact of genetic analysis on biological classification, Linnaeus' naming system endures as a simple and adaptable means of identification.

The 18th century was also a time when European explorers were fanning out across the globe, finding ever more plants and animals new to science.

“There got to be more and more things that needed to be described, and the names were becoming more and more complex,” says Knapp.

Linnaeus, a botanist with a talent for noticing details, first used what he called “trivial names” in the margins of his 1753 book Species Plantarum . He intended the simple Latin two-word construction for each plant as a kind of shorthand, an easy way to remember what it was.

“It reflected the adjective-noun structure in languages all over the world,” Knapp says of the trivial names, which today we know as genus and species. The names moved quickly from the margins of a single book to the center of botany, and then all of biology. Linnaeus started a revolution — positioning him as one of the greatest scientists — but it was an unintentional one.

Today we regard Linnaeus as the father of taxonomy, which is used to sort the entire living world into evolutionary hierarchies, or family trees. But the systematic Swede was mostly interested in naming things rather than ordering them, an emphasis that arrived the next century with Charles Darwin.

As evolution became better understood and, more recently, genetic analysis changed how we classify and organize living things, many of Linnaeus’ other ideas have been supplanted. But his naming system, so simple and adaptable, remains.

“It doesn’t matter to the tree in the forest if it has a name,” Knapp says. “But by giving it a name, we can discuss it. Linnaeus gave us a system so we could talk about the natural world.”

10. Rosalind Franklin: The Hero Denied Her Due

Rosalind Franklin, a brilliant and tenacious scientist, transformed the world of molecular biology. Her pioneering work in X-ray crystallography and groundbreaking research on the structure of DNA propelled her to the forefront of scientific discovery. Yet, her remarkable contributions were often overshadowed, and her legacy is not only one of scientific excellence but also a testament to the persistence and resilience of a scientist who deserved greater recognition in her time.

Rosalind Franklin , one of the greatest scientists of her time, was a British-born firebrand and perfectionist. While she had a reputation for being somewhat reserved and difficult to connect with, those who knew her well found her to be outgoing and loyal. Franklin's brilliance shone through in her work, particularly in the field of X-ray crystallography , an imaging technique that revealed molecular structures based on scattered X-ray beams. Her early research on the microstructures of carbon and graphite remains influential in the scientific community.

However, it was Rosalind Franklin's groundbreaking work with DNA that would become her most significant contribution. During her time at King's College London in the early 1950s, she came close to proving the double-helix theory of DNA. Her achievement was epitomized in "photograph #51," which was considered the finest image of a DNA molecule at that time. Unfortunately, her work was viewed by others, notably James Watson and Francis Crick.

Watson saw photograph #51 through her colleague Maurice Wilkins, and Crick received unpublished data from a report Franklin had submitted to the council. In 1953, Watson and Crick published their iconic paper in "Nature," loosely citing Franklin's work, which also appeared in the same issue.

Rosalind Franklin's pivotal role in elucidating the structure of DNA was overlooked when the Nobel Prize was awarded in 1962 to James Watson, Francis Crick, and Maurice Wilkins. This omission is widely regarded as one of the major snubs of the 20th century in the field of science.

Despite her groundbreaking work and significant contributions to science, Franklin's life was tragically cut short. In 1956, at the height of her career, she was diagnosed with ovarian cancer, possibly linked to her extensive X-ray work. Remarkably, she continued to work in the lab until her passing in 1958 at the young age of 37.

Rosalind Franklin's legacy endures not only for her achievements but also for the recognition she deserved but did not receive during her lifetime. She was known for her extreme clarity and perfectionism in all her scientific endeavors, changing the field of molecular biology. While many remember her for her contributions, she is also remembered for how her work was overshadowed and underappreciated, a testament to her enduring influence on the world of science.

“As a scientist, Miss Franklin was distinguished by extreme clarity and perfection in everything she undertook,” Bernal wrote in her obituary, published in Nature . Though it’s her achievements that close colleagues admired, most remember Franklin for how she was forgotten.

More Greatest Scientists: Our Personal Favorites

Isaac Asimov   (1920–1992) Asimov was my gateway into science fiction, then science, then everything else. He penned some of the genre’s most iconic works — fleshing out the laws of robotics, the messiness of a galactic empire, the pitfalls of predicting the future — in simple, effortless prose. A trained biochemist, the Russian-born New Yorker wrote prolifically, producing over 400 books, not all science-related: Of the 10 Dewey Decimal categories, he has books in nine. — B.A.

Richard Feynman   (1918–1988) Feynman played a part in most of the highlights of 20th-century physics. In 1941, he joined the Manhattan Project. After the war, his Feynman diagrams — for which he shared the ’65 Nobel Prize in Physics — became the standard way to show how subatomic particles interact. As part of the 1986 space shuttle Challenger disaster investigation, he explained the problems to the public in easily understandable terms, his trademark. Feynman was also famously irreverent, and his books pack lessons I live by. — E.B.

Robert FitzRoy   (1805–1865) FitzRoy suffered for science, and for that I respect him. As captain of the HMS Beagle , he sailed Charles Darwin around the world, only to later oppose his shipmate’s theory of evolution while waving a Bible overhead. FitzRoy founded the U.K.’s Met Office in 1854, and he was a pioneer of prediction; he coined the term weather forecast. But after losing his fortunes, suffering from depression and poor health, and facing fierce criticism of his forecasting system, he slit his throat in 1865. — C.E.

Jean-Baptiste Lamarck   (1744–1829) Lamarck may be remembered as a failure today, but to me, he represents an important step forward for evolutionary thinking . Before he suggested that species could change over time in the early 19th century, no one took the concept of evolution seriously. Though eventually proven wrong, Lamarck’s work brought the concept of evolution into the light and would help shape the theories of a young Charles Darwin. Science isn’t all about dazzling successes; it’s also a story of failures surmounted and incremental advances. — N.S.

Lucretius   (99 B.C.–55 B.C.) My path to the first-century B.C. Roman thinker Titus Lucretius Carus started with Ralph Waldo Emerson and Michele de Montaigne, who cited him in their essays. Lucretius’ only known work, On the Nature of Things, is remarkable for its foreshadowing of Darwinism, humans as higher primates, the study of atoms and the scientific method — all contemplated in a geocentric world ruled by eccentric gods. — M.B.

Katharine McCormick   (1875–1967) McCormick planned to attend medical school after earning her biology degree from MIT in 1904. Instead, she married rich. After her husband’s death in 1947, she used her inheritance to provide crucial funding for research on the hormonal birth control pill . She also fought to make her alma mater more accessible to women, leading to an all-female dormitory, allowing more women to enroll. As a feminist interested in science, I’d love to be friends with this badass advocate for women’s rights. — L.S.

John Muir   (1838–1914) In 1863, Muir abandoned his eclectic combination of courses at the University of Wisconsin to wander instead the “University of the Wilderness” — a school he never stopped attending. A champion of the national parks (enough right there to make him a hero to me!), Muir fought vigorously for conservation and warned, “When we try to pick out anything by itself, we find it hitched to everything else in the Universe.” It’s a reminder we need today, more than ever. — Elisa Neckar

Rolf O. Peterson   (1944–) Peterson helms the world’s longest-running study of the predator-prey relationship in the wild, between wolves and moose on Isle Royale in the middle of Lake Superior. He’s devoted more than four decades to the 58-year wildlife ecology project, a dedication and passion indicative, to me, of what science is all about. As the wolf population has nearly disappeared and moose numbers have climbed, patience and emotional investment like his are crucial in the quest to learn how nature works. — Becky Lang

Marie Tharp   (1920–2006) I love maps. So did geologist and cartographer Tharp . In the mid-20th century, before women were permitted aboard research vessels, Tharp explored the oceans from her desk at Columbia University. With the seafloor — then thought to be nearly flat — her canvas, and raw data her inks, she revealed a landscape of mountain ranges and deep trenches. Her keen eye also spotted the first hints of plate tectonics at work beneath the waves. Initially dismissed, Tharp’s observations would become crucial to proving continental drift. — G.T.

Making Science Popular With Other Greatest Scientists

Science needs to get out of the lab and into the public eye. Over the past hundred years or so, these other greatest scientists have made it their mission. They left their contributions in multiple sciences while making them broadly available to the general public.

Sean M. Carroll  (1966– ) : The physicist (and one-time  Discover  blogger) has developed a following among space enthusiasts through his lectures, television appearances and books, including   The Particle at the End of the Universe, on the Higgs boson .

Rachel Carson   (1907–1964) : With her 1962 book  Silent Spring , the biologist energized a nascent environmental movement. In 2006,  Discover  named  Silent Spring  among the top 25 science books of all time.

Richard Dawkins   (1941– ) : The biologist, a charismatic speaker, first gained public notoriety in 1976 with his book  The Selfish Gene , one of his many works on evolution .

Jane Goodall   (1934– ) : Studying chimpanzees in Tanzania, Goodall’s patience and observational skills led to fresh insights into their behavior — and led her to star in a number of television documentaries.

Stephen Jay Gould   (1941–2002) : In 1997, the paleontologist Gould was a guest on  The Simpson s, a testament to his broad appeal. Among scientists, Gould was controversial for his idea of evolution unfolding in fits and starts rather than in a continuum.

Stephen Hawking   (1942–2018) : His books’ titles suggest the breadth and boldness of his ideas:  The Universe in a Nutshell, The Theory of Everything . “My goal is simple,” he has said. “It is a complete understanding of the universe, why it is as it is and why it exists at all.”

Aldo Leopold   (1887–1948) : If Henry Thoreau and John Muir primed the pump for American environmentalism, Leopold filled the first buckets . His posthumously published  A Sand County Almanac  is a cornerstone of modern environmentalism.

Bill Nye   (1955– ) : What should an engineer and part-time stand-up comedian do with his life? For Nye, the answer was to become a science communicator . In the ’90s, he hosted a popular children’s science show and more recently has been an eloquent defender of evolution in public debates with creationists.

What Are the 10 Greatest Inventions of Our Time?

Before you consider, here are a few opinions from Scientific American readers in 1913 on what makes a great invention

By Daniel C. Schlenoff

A competition sponsored in 1913 by Scientific American asked for essays on the 10 greatest inventions. The rules: “our time” meant the previous quarter century, 1888 to 1913; the invention had to be patentable and was considered to date from its “commercial introduction.”

Perception is at the heart of this question. Inventions are most salient when we can see the historical changes they cause. In 2013 we might not appreciate the work of Nikola Tesla or Thomas Edison on a daily basis, as we are accustomed to electricity in all its forms, but we are very impressed by the societal changes caused by the Internet and the World Wide Web (both of which run on alternating-current electricity, by the way). A century from now they might be curious as to what all the fuss was about. The answers from 1913 thus provide a snapshot of the perceptions of the time.

Following are excerpts from the first- and second-prize essays, along with a statistical tally of all the entries that were sent in.

The first-prize essay was written by William I. Wyman, who worked in the U.S. Patent Office in Washington, D.C., and was thus well informed on the progress of inventions. His list was:

1. The electric furnace (1889) It was “the only means for commercially producing Carborundum (the hardest of all manufactured substances).” The electric furnace also converted aluminum “from a merely precious to very useful metal” (by reducing it’s price 98 percent), and was “radically transforming the steel industry.”

2. The steam turbine, invented by Charles Parsons in 1884 and commercially introduced over the next 10 years. A huge improvement in powering ships, the more far-reaching use of this invention was to drive generators that produced electricity.

3. The gasoline-powered automobile. Many inventors worked toward the goal of a “self-propelled” vehicle in the 19th century. Wyman gave the honor specifically to Gottleib Daimler for his 1889 engine, arguing: “a century's insistent but unsuccessful endeavor to provide a practical self-propelled car proves that the success of any type that once answered requirements would be immediate. Such success did come with the advent of the Daimler motor, and not before.”

4. The moving picture. Entertainment always will be important to people. “The moving picture has transformed the amusements of the multitude.” The technical pioneer he cited was Thomas Edison.

5. The airplane. For “the Realization of an age-long dream” he gave the laurels of success to the Wright brothers, but apart from its military use reserved judgment on the utility of the invention: “It presents the least commercial utility of all the inventions considered.”

6. Wireless Telegraphy. Systems for transmitting information between people have been around for centuries, perhaps millennia. Telegraph signals got a speed boost in the U.S. from Samuel Morse and Alfred Vail. Wireless telegraphy as invented by Guglielmo Marconi, later evolving into radio, set information free from wires.

7. The cyanide process. Sounds toxic, yes? It appears on this list for only one reason: It is used to extract gold from ore. “Gold is the life blood of trade,” and in 1913 it was considered to be the foundation for international commerce and national currencies.

8. The Nikola Tesla induction motor. “This epoch-making invention is mainly responsible for the present large and increasing use of electricity in the industries.” Before people had electricity in their homes, the alternating current–producing motor constructed by Tesla supplied 90 percent of the electricity used by manufacturing.

9. The Linotype machine. The Linotype machine enabled publishers—largely newspapers—to compose text and print it much faster and cheaper. It was an advance as large as the invention of the printing press itself was over the painstaking handwritten scrolls before it. Pretty soon we won’t be using paper for writing and reading, so the history of printing will be forgotten anyway.

10. The electric welding process of Elihu Thomson. In the era of mass production, the electric welding process enabled faster production and construction of better, more intricate machines for that manufacturing process.

The turbine invented by Charles Parsons powered ships. Assembled in numbers, they provided an efficient means of driving electrical generators and producing that most useful commodity. Image: Scientific American - November 1, 1913

The second-prize essay, by George M. Dowe, also of Washington, D.C., who may have been a patent attorney, was more philosophical. He divided his inventions into those aiding three broad sectors: production, transportation and communication.

1. Electrical fixation of atmospheric nitrogen. As natural fertilizer sources were depleted during the 19th century, artificial fertilizers enabled the further expansion of agriculture.

2. Preservation of sugar-producing plants. George W. McMullen of Chicago is credited with the discovery of a method for drying sugar cane and sugar beets for transport. Sugar production became more efficient and its supply increased by leaps and bounds, like a kid on a “sugar buzz.” Maybe this is one invention we could have done without. But I digress.

3. High-speed steel alloys. By adding tungsten to steel, “tools so made were able to cut at such a speed that they became almost red hot without losing either their temper or their cutting edge” The increase in the efficiency of cutting machines was “nothing short of revolutionary.”

4. Tungsten-filament lamp. Another success of chemistry. After tungsten replaced carbon in its filament, the lightbulb was considered “perfected.” As of 2013 they are being phased out worldwide in favor of compact fluorescent bulbs, which are four times as efficient.

5. The airplane. Not yet in wide use as transportation in 1913, but “To [Samuel] Langley and to the Wright brothers must be awarded the chief honors in the attainment of mechanical flight.” In 2013 the annoying aspects of commercial airline flying make transportation by horse and buggy seem a viable alternative.

6. The steam turbine. As with Mr. Wyman, the turbine deserved credit not only “in the utilization of steam as a prime mover” but in its use in the “generation of electricity.”

7. Internal combustion engine. As a means of transportation, Dowe gives the greatest credit to “Daimler, Ford and Duryea.” Gottleib Daimler is a well-known pioneer in motor vehicles. Henry Ford began production of the Model T in 1908 and it was quite popular by 1913. Charles Duryea made one of the earliest commercially successful petrol-driven vehicles, starting in 1896.

8. The pneumatic tire. Cars for personal transportation were an improvement on railways. “What the track has done for the locomotive, the pneumatic tire has done for the vehicle not confined to tracks.” Credit is given to John Dunlop and William C. Bartlet, who each had a milestone on the road (pun intended) to successful automobile and bicycle tires.

9. Wireless communication. Marconi was given the credit for making wireless “commercially practical.” Dowe also makes a comment that could apply equally to the rise of the World Wide Web, stating that wireless was “devised to meet the needs of commerce primarily, but incidentally they have contributed to social intercourse.”

10. Composing machines. The giant rotary press was quite capable of churning out masses of printed material. The bottleneck in the chain of production was composing the printing plates. The Linotype and the Monotype dispensed with that bottleneck.

The essays sent in were compiled to come up with a master list of inventions that were considered to be the top 10. Wireless telegraphy was on almost everyone’s list. The “aeroplane” came in second, although it was considered important because of its potential, not because there were so many airplanes in the sky. Here are the rest of the results:

There were also mentions for Luther Burbank's agricultural work (23); Louis Pasteur and vaccination work (20); acetylene gas from carbide (17); mercury-vapor lamp (7); preservation of sugar-producing plants (7); combined motion picture and talking machine (10); Edison's storage battery (6); automatic player piano (4); Pulmotor (a respirator machine) (4); telephone (4).

Essays About Science: Top 12 Examples and Prompts

Science can explain almost every aspect of our lives; if you want to write essays about science, start by reading our guide.

The word “science” comes from the Latin word Scientia or “knowledge,” It does indeed leave us with no shortage of knowledge as it advances to extraordinary levels. It is present in almost every aspect of our lives, allowing us to live the way we do today and helping us improve society. 

In the 21st century, we see science everywhere. It has given us the technology we deem “essential” today, from our mobile phones to air conditioning units to lightbulbs and refrigerators. Yet, it has also allowed us to learn so much about the unknown, such as the endless vacuum of space and the ocean’s mysterious depths. It is, without a doubt, a vehicle for humanity to obtain knowledge and use this knowledge to flourish. 

To start writing essays about science, look at some of our featured essay examples below. 

1. The challenging environment for science in the 21st century by Nithaya Chetty 

2. disadvantages of science by ella gray, 3. reflections from a nobel winner: scientists need time to make discoveries by donna strickland.

• 4.  ​​The fact of cloning by Cesar Hill

5. T. Rex Like You Haven’t Seen Him: With Feathers by Jason Farago

6. common, cheap ingredients can break down some ‘forever chemicals’ by jude coleman, 1. what is science, 2. a noteworthy scientist, 3. why is it important to study science, 4. are robots a net positive for society, 5. types of sciences, 6. science’s role in warfare.

“Open-ended, unfettered science in its purest form has, over the centuries, been pursued in the interests of understanding nature in a fundamental way, and long may that continue. Scientific ideas and discoveries have often been very successfully exploited for commercial gain and societal improvements, and much of the science system today the world over is designed to push scientists in the direction of more relevance.”

For South Africa to prosper, Chetty encourages cooperation and innovation among scientists. He discusses several problems the country faces, including the politicization of research, a weak economy, and misuse of scientific discoveries. These challenges, he believes, can be overcome if the nation works as one and with the international community and if the education system is improved. 

“Technology can make people lazy. Many people are already dependent and embrace this technology. Like students playing computer games instead of going to school or study. Technology also brings us privacy issues. From cell phone signal interceptions to email hacking, people are now worried about their once private information becoming public knowledge and making profit out of video scandals.”

Gray discusses the adverse effects technology, a science product, has had on human life and society. These include pollution, the inability to communicate properly, and laziness. 

She also acknowledges that technology has made life easier for almost everyone but believes that technology, as it is used now, is detrimental; more responsible use of technology is ideal.

“We must give scientists the opportunity through funding and time to pursue curiosity-based, long-term, basic-science research. Work that does not have direct ramifications for industry or our economy is also worthy. There’s no telling what can come from supporting a curious mind trying to discover something new.”

Strickland, a Nobel Prize winner, explains that a great scientific discovery can only come with ample time for scientists to research, using her work as an example. She describes her work on chirped pulse amplification and its possible applications, including removing brain tumors. Her Nobel-awarded work was done over a long time, and scientists must be afforded ample time and funding to make breakthroughs like hers. 

4.  ​​ The fact of cloning by Cesar Hill

“Any research into human cloning would eventually need to be tested on humans. Cloning might be used to create a “perfect human”. Cloning might have a detrimental effect family relationship. However the debate over cloning has more pros out weighting the cons, giving us a over site of the many advantages cloning has and the effects of it as well. Cloning has many ups and downs nevertheless there are many different ways in which it can be used to adapt and analyse new ways of medicine.”

Hill details both the pros and cons of cloning. It can be used for medical purposes and help us understand genetics more, perhaps even allowing us to prevent genetic diseases in children. However, it is expensive, and many oppose it on religious grounds. Regardless, Hill believes that the process has more advantages than disadvantages and is a net good. 

“For the kids who will throng this new exhibition, and who will adore this show’s colorful animations and fossilized dino poop, T. rex may still appear to be a thrilling monster. But staring in the eyes of the feather-flecked annihilators here, adults may have a more uncanny feeling of identification with the beasts at the pinnacle of the food chain. You can be a killer of unprecedented savagery, but the climate always takes the coup de grâce.”

In his essay, Farago reviews an exhibition on the Tyrannosaurus Rex involving an important scientific discovery: it was a feathered dinosaur. He details the different displays in the exhibition, including models of other dinosaurs that helped scientists realize that the T-Rex had feathers. 

“Understanding this mechanism is just one step in undoing forever chemicals, Dichtel’s team said. And more research is needed: There are other classes of PFAS that require their own solutions. This process wouldn’t work to tackle PFAS out in the environment, because it requires a concentrated amount of the chemicals. But it could one day be used in wastewater treatment plants, where the pollutants could be filtered out of the water, concentrated and then broken down.”

Coleman explains a discovery by which scientists were able to break down a perfluoroalkyl and polyfluoroalkyl substance, a “forever chemical” dangerous to the environment. He explains how they could break the chemical bond and turn the “forever chemical” into something harmless. This is important because pollution can be reduced significantly, particularly in the water. 

Writing Prompts on Essays about Science

“Science” is quite a broad term and encompasses many concepts and definitions. Define science, explain what it involves and how we can use it, and give examples of how it is present in the world. If you want, you can also briefly discuss what science means to you personally. 

Many individuals have made remarkable scientific discoveries, contributing to the wealth of knowledge we have acquired through science. For your essay, choose one scientist you feel has made a noteworthy contribution to their field. Then, give a brief background on the scientists and explain the discovery or invention that makes them essential. 

Consider what it means to study science: how is it relevant now? What lessons can we learn from science? Then, examine the presence of science in today’s world and write about the importance of science in our day-to-day lives- be sure to give examples to support your points. Finally, in your essay, be sure to keep in mind the times we are living in today.

When we think of science, robots are often one of the first things that come to mind. However, there is much to discuss regarding safety, especially artificial intelligence. Discuss the pros and cons of robots and AI, then conclude whether or not the benefits outweigh the disadvantages. Finally, provide adequate evidence to reinforce your argument and explain it in detail. 

From biology to chemistry to physics, science has many branches, each dealing with different aspects of the world and universe. Choose one branch of science and then explain what it is, define basic concepts under this science, and give examples of how it is applied: Are any inventions requiring it? How about something we know today thanks to scientific discovery? Answer these questions in your own words for a compelling essay.

Undoubtedly, technology developed using science has had devastating effects, from nuclear weapons to self-flying fighter jets to deadly new guns and tanks. Examine scientific developments’ role in the war: Do they make it more brutal? Or do they reduce the casualties? Make sure to conduct ample research before writing your essay; this topic is debatable.

500 Words Essay on My Favorite Scientist

Every epoch in human history has been marked by the contributions of countless scientists. Their relentless pursuit of knowledge, questioning the status quo, and challenging the unknown have led to numerous breakthroughs that have shaped our world. Among the pantheon of these intellectual giants, my favorite scientist is Albert Einstein, a man whose name is synonymous with genius and whose work has significantly influenced modern physics.

Albert Einstein was born in 1879 in Ulm, Germany. Despite being a mediocre student in his early years, his fascination with the mysteries of science was palpable. He was largely self-taught, devouring books on science, mathematics, and philosophy. Einstein’s academic journey was not a traditional one, marked by rebelliousness and a knack for independent thinking. His unique approach to learning laid the foundation for his future achievements.

The Miracle Year and Theory of Relativity

In 1905, often referred to as his ‘Annus Mirabilis’ or ‘Miracle Year’, Einstein published four groundbreaking papers in the field of physics. These papers, which tackled the photoelectric effect, Brownian motion, special relativity, and mass-energy equivalence (E=mc^2), revolutionized the scientific community’s understanding of the natural world. However, his most significant contribution came in 1915 with the general theory of relativity, a radical reinterpretation of gravitational theory. This theory has since served as a cornerstone for modern physics and cosmology.

Einstein’s theories have had profound implications, not only in the realm of science but also in our daily lives. His work paved the way for the development of lasers, nuclear power, fiber optics, and even GPS technology. Beyond his scientific contributions, Einstein was a vocal advocate for civil rights, education, and pacifism. His philosophical reflections on science, life, and the universe continue to inspire and provoke thought.

Albert Einstein’s life and work embody the essence of scientific inquiry and intellectual courage. His groundbreaking theories, coupled with his philosophical wisdom, have left an indelible mark on human history. Einstein’s pursuit of truth, his unwavering curiosity, and his ability to challenge established norms make him my favorite scientist.

The device was so popular that farmers began building their own versions of it despite Whitney’s patent.

He went on to champion interchangeable parts for weapons, though there is some debate on whether he was truly the first person to pioneer the technology.

Elijah McCoy

Elijah McCoy was a mechanical engineer and inventor. He’s credited with inventing a lubrication device that distributes oil over an engine’s moving parts. This was revolutionary for train travel, because it allowed them to run for long periods of time without stopping for maintenance.

Essay on My Favourite Scientist in English For Students

We are Sharing an Essay on My Favourite Scientist in English for students. In this article, we have tried our best to provide a Short essay on My Favourite Scientist for Class 2,3,4,5,6,7,8,9,10,11,12 in 100, 250, 300, 400, 500 words.

My Favourite Scientist Essay

Science is a search for knowledge regarding the nature of the universe. Scientists devote their whole life to searching for the answers as to how certain things happen. Scientists carry out experiments to test their theories and observations, and then make conclusions that become laws of science.

Different scientists have carried out observations and experiments and discovered different things. For example, Sir Issac Newton discovered the force of gravity, the Wright brothers invented the aeroplane and Thomas Alva Edison has a number of inventions to his credit.

My favourite scientist is Edison (1847-1931). He was a famous American inventor whose inventions have had a dramatic effect on modern life. As a boy, he sold newspapers at railroad stations and learnt how to use the telegraph machine for sending messages. It was during these years as a telegraphist that he invented many electrical gadgets. People began to pay for his inventions and his fame spread. In 1876 he moved to Mento Park, New Jersey and the world came to know him as the “Wizard of Mento Park”. A year later he invented the phonograph or record player.

In 1879 he invented one of the most useful of things -the electric light bulb. The arc light used in his time was costly and could not be used on a large scale. He thought of a filament that could produce light when charged with electricity. He tried various materials but they were soon burnt out. He finally obtained a special type for the purpose. The lamp he now made burnt for several days and nights. The invention was perfected and today there is light not only in the streets but in every house. Edison truly converted the darkness of night into light.

Another great contribution that Edison made to the world of science is his work on cinematography.

Edison has more than 1,100 inventions to his credit and it is impossible to mention all of them. Edison is certainly a scientist to be revered, for his inventions have now not only become indispensable to mankind but have served as a stepping stone for advanced research.

Who can help me write my essay?

At the end of the school year, students have no energy left to complete difficult homework assignments. In addition, inspiration is also lacking, so there are only a few options:

• do not write a scientific work;
• write it badly;
• delegate these responsibilities to other people.

Most often, people choose the latter option, which is why companies have appeared on the Internet offering to take full responsibility.

When you visit the site, the managers clarify all the details in order to correctly design the article. They select a person who is well versed in the topic of the report and give him your task.

You will not be able to personally communicate with the writer who will do your work. This is done to ensure that all your personal data is confidential. The client, of course, can make edits, follow the writing of each section and take part in the correction, but it is impossible to communicate with the team.

Do not worry that you will not meet personally with the site team, because throughout the entire cooperation our managers will keep in touch with each client.
