Summary of Course Content and Activities

This course explores the complex system of Earth's interacting parts, emphasizing the positive impact understanding these core elements can have on the environment and society. It is structured into four units:  Investigating Properties of Matter, Energy Transfer Technologies, From Life to Lifestyle, and Matter and Energy in the Biosphere.  In the first unit, students learn the safe handling of chemicals and investigate the properties of various matter, including elements and compounds. The second unit focuses on energy transfer technologies, emphasizing the importance of design for safety, efficiency, and reducing reliance on nonrenewable resources. The third unit delves into life processes at multiple levels, highlighting the importance of a healthy diet and lifestyle. The final unit examines the sun's role in sustaining life, the recycling of matter, and the impact of human activities on biosphere sustainability.

Philosophy statement for teaching this course

The following goals for Canadian science education are addressed through the Alberta science program. Science education will:

• encourage students at all grade levels to develop a critical sense of wonder and curiosity about scientific and technological endeavours
• enable students to use science and technology to acquire new knowledge and solve problems, so that they may improve the quality of their own lives and the lives of others
• prepare students to critically address science-related societal, economic, ethical and environmental issues
• provide students with a foundation in science that creates opportunities for them to pursue progressively higher levels of study, prepares them for science-related occupations, and engages them in science-related hobbies appropriate to their interests and abilities
• enable students, of varying aptitudes and interests, to develop a knowledge of the wide spectrum of careers related to science, technology and the environment.

Science 24 is the second course in the Science 14-24 sequence, covering four main units. In  Applications of Matter and Chemical Change , students explore simple chemical reactions and the creation of materials from basic components, emphasizing the widespread use of chemical technologies.  Understanding Common Energy Conversion Systems  focuses on various energy transformations in biological, chemical, physical, and technological systems, highlighting the conservation of energy and the efficiency of fossil fuel use.  Disease Defence & Human Health  delves into the body’s defence mechanisms and medical techniques to reduce exposure to toxins and pathogens, considering the complexities of minimizing genetic disorders.  Motion, Change & Transportation Safety  examines new safety systems in transportation grounded in the law of conservation of momentum and introduces concepts of speed, distance, time, and force. This comprehensive course aims to enhance students' understanding of fundamental scientific principles and their applications in everyday life.

Introduction

This DataScience course is an advanced course starting covering all the crucial topics of datascience like Web Scrapping, Statistics, Visualizations, EDA, Machine Learning Algorithmns, Implementation of ML algorithmns in end to end Projects using pipelines, Deep Learning, Computer Vision and NLP.

The course is also currently going on so it will be updated regularly whenever an assignment is given .

The Assignments are names in the format : Project_WeekNo_AssignmentNumberofthatWeek_ConceptUsedintheAssignment.ipynb .

In the solutions while solving the assignments I have also gone a bit deep by exploring the web and learning new things which are also a part in some assignments. Also, I have made notes for all the topics and a detailed repository will be made soon in a much more structured format including some pratice codes, notes, assignment questions and solutions.

All the assignments are completed using Jupyter notebook in a way I understood the concepts feel free to go through them as they cover almost the most vital topics involved during the interviews.

Performance

There is also a scoreboard in the course to encourage people to complete assignments correctly and on timely basis and currently I am proudly at the top of the leaderboard ❗❗

Remains of 14th-century gauntlet discovered in Oslo's medieval harbor

Archaeologists excavating Oslo's medieval harbor have unearthed the remnants of a 14th-century gauntlet.

An excavation in Oslo's former harbor has yielded the remains of a rare iron gauntlet, likely lost by a medieval knight in the 14th century. Archaeologists with the Norwegian Institute for Cultural Heritage Research (NIKU) discovered the piece of armor while metal detecting as part of their investigation of the old harbor area.

Oslo was founded as a medieval city and harbor around 1050. But in 1624, after a fire ravaged the city, the Norwegian king Christian IV moved Oslo across the bay. In the centuries since, development of the old harbor, including the building of piers and warehouses, steadily expanded outward into the bay as the ocean retreated.

Archaeologists have undertaken two major excavations of the old harbor area of Oslo, first between 2019 and 2020 and then from 2022 to 2023. According to NIKU archaeologist Håvard Hegdal , their discoveries include many discarded objects from the medieval and Renaissance periods, including shipwrecks, ceramics, footwear, ropes, the remains of butchered animals and a large number of weapons.

"The gauntlet was found some 40 meters [131 feet] out in the harbor," Hegdal told Live Science in an email. "So it could only have been dropped from a ship, though we have no good explanation how something like that could have happened."

Usually made out of iron, these metal gloves, which were used to protect a person's hands and wrists, were invented in the early 14th century, when European soldiers and knights upgraded from chain mail to plate armor. But archaeological discoveries of gauntlets are rare, particularly early examples, because metal corrodes quickly and easily in the ground and because iron was often reused and reforged in the Middle Ages. However, a well-preserved right-handed gauntlet from the 14th century was recently found in Switzerland.

The Oslo gauntlet may date to the same century. "It was found more or less directly below an area-wide layer of blue clay which must have come from a significant quick clay slide which we have dated to about 1380," Hegdal said. "The gauntlet might have been lost in relation to the landslide itself and the resulting waves."

Little of the Oslo gauntlet remains, however. It is largely an imprint of the armor, with remnants of small nails and a possible buckle that the archaeologists were able to see in X-rays . And it is unknown whether the gauntlet was new or old at the time it was lost. Immediately following the Black Death , commercial goods that were previously scarce — such as plate armor — became more common due to the decimation of the population, Hegdal said. "The gauntlet might simply have been rusted and broken from neglect and tossed away."

— Medieval grave of 'very, very powerful' man and his 4-foot-long sword unearthed in Sweden

But NIKU's excavations have also revealed many weapons — daggers and knives for the most part, but also swords, spears and axes. "Our hypothesis is that these were discarded due to a prohibition on weapons or long blades, based on similar regulations in other medieval cities," Hegdal said, which might be an indication of a form of customs control in the harbor.

Fully understanding medieval Oslo, though, is complicated. Many Norwegian documents were lost in a fire in 1728 , and Oslo's medieval city laws are not preserved. But NIKU's archaeological excavation , which is due to wrap up in November of this year, may shed new light on Oslo's medieval past.
