Study Notes
Science is an interdisciplinary field of study dedicated to understanding our world through observation and experimentation. It encompasses several major branches such as physics, biology, and chemistry, each contributing unique insights into how the universe works. Physics deals with physical laws governing everything from celestial objects like planets and stars to subatomic particles like electrons and protons. Biology studies living organisms, including human beings, animals, plants, insects, and microbes, exploring their structure, function, growth, reproduction, behavior, evolution, distribution, and adaptation. Chemistry investigates matter, its composition, changes, interactions, properties, energy states, and the relative quantities or qualities of things.
Physics has been around since ancient times when philosophers pondered over nature's fundamental principles. Later, Isaac Newton developed the concept of gravity, one of the four basic forces that shape the universe. Albert Einstein revolutionized physics by developing general relativity, describing the large scale motions of the cosmos while quantum mechanics explained the smallest possible scales we can measure. The Large Hadron Collider near Geneva, Switzerland, discovered the Higgs boson particle, which helps us understand why some materials have mass while others do not.
Biology was originally called natural philosophy because it focused on observing nature. In modern times, biologists distinguish among different groups of living creatures based on shared characteristics. They also address issues related to ecology, population genetics, diseases, and conservation efforts. For instance, Charles Darwin proposed his theory of biological evolution, explaining how species change over time due to genetic mutations and environmental pressures.
Chemistry started out as alchemy before evolving into a rigorous scientific discipline. Scientists learned how to break down complex molecules into simpler ones, create new compounds never seen before, synthesize pure elements, analyze mixtures, purify samples, determine chemical compositions, and more. Modern chemistry uses advanced techniques to prepare materials used every day — medicines, fertilizers, plastics, metals, and many other products. Nobel Prize winner Marie Curie made important contributions to this field.
These three fields work together to reveal the secrets hidden within the world. Each branch builds upon knowledge gained by those who came before them, constantly advancing humanity's understanding of reality. Whether you're studying astronomy, medicine, agriculture, engineering, computer science, or any other area where science applies, chances are good that physicists, biologists, and chemists helped make it all possible.
