Takeaways

• 😀 Science refers to the acquisition of knowledge based on the scientific method, involving testing, study, observation, and experimentation.
• 😀 The first inhabitants of Earth unknowingly practiced science by developing techniques for hunting, farming, creating fire, and building homes.
• 😀 Common sense is subjective and varies from person to person and group to group, while science is based on objective methods and experimentation.
• 😀 Major scientific discoveries emerged from the emphasis on ideas and experimentation, rather than simply relying on common knowledge.
• 😀 Archimedes made an important contribution to science when he discovered the principle of buoyancy while taking a bath, leading to the formulation of Archimedes' principle.
• 😀 Isaac Newton's discovery of the force of gravity, inspired by the fall of an apple, was a key step in the development of the theory of universal gravitation.
• 😀 The history of science spans from ancient Greece with figures like Aristotle, Pythagoras, and Thales, to the Renaissance with Copernicus, Galileo, and Kepler.
• 😀 Modern scientists, such as Rosalind Franklin, Victoria Casp, and Sandra Dias, have made significant contributions to scientific advancements.
• 😀 Scientific knowledge and advancements have improved many sectors, including health, food, the environment, technology, and energy.
• 😀 Science contributes to the improvement of life quality, intellectual growth, and cultural development by addressing major challenges and answering crucial questions.

Q & A

What is the focus of the first week of the PET 3 course?

The first week of the PET 3 course focuses on science, scientific knowledge, and the development of techniques used by early humans to hunt, plant, gather food, create fire, and build their houses.

How did early humans unknowingly contribute to science?

Early humans unknowingly contributed to science by developing techniques for survival such as hunting, farming, creating fire, and building shelter, all of which were based on experimental knowledge.

What is the difference between science and common sense?

Science involves the acquisition of knowledge based on the scientific method, which is tested and obtained through studies, observations, and experiments. Common sense, on the other hand, refers to subjective knowledge based on everyday experience, which can vary between individuals, groups, and regions.

How do great scientific discoveries relate to the value placed on ideas and experimentation?

Great discoveries have arisen from the value placed on ideas and experimentation, with a shift from subjective beliefs to objective, tested knowledge through observation and scientific methods.

What was Archimedes' contribution to science, and how did he make his discovery?

Archimedes contributed to the field of hydrostatics by formulating the principle of buoyancy, which he discovered while taking a bath. He realized that the volume of water displaced by his body in the bath was proportional to the volume of his body.

What famous phrase did Archimedes reportedly shout after making his discovery?

After making his discovery, Archimedes is said to have run through the streets shouting 'Eureka! Eureka!' which means 'I have found it!'

What was Isaac Newton's major contribution to science?

Isaac Newton's major contribution to science was his formulation of the theory of universal gravitation, which proposed that a force attracts objects towards the Earth.

How did Isaac Newton supposedly come up with the concept of gravity?

Isaac Newton is famously said to have come up with the concept of gravity when an apple fell on his head while he was sitting under an apple tree, prompting him to think about the force that caused objects to fall towards the Earth.

Who are some key historical figures in the development of scientific thought?

Key historical figures in the development of scientific thought include ancient Greek philosophers such as Aristotle, Pythagoras, and Thales, as well as Renaissance scientists like Copernicus, Galileo, and Kepler.

How do contemporary scientists contribute to society?

Contemporary scientists like Rosalind Franklin, Victoria Casp, and Sandra Dias contribute to society through groundbreaking research in fields such as health, food, environment, technology, and energy, improving quality of life and enriching societies intellectually, socially, and culturally.
