The World of Science

Science is humanity's most powerful tool for understanding the universe. It is divided into many branches: physics studies matter and energy; chemistry studies the composition and reactions of substances; biology studies living organisms; and earth science studies our planet's systems. The scientific method - Forming hypotheses, testing them through experiments, and revising theories based on evidence - Is the foundation of all scientific progress.

Some of the most important scientific discoveries in history include Isaac Newton's laws of motion and universal gravitation (1687), Charles Darwin's theory of evolution by natural selection (1859), Albert Einstein's theory of relativity (1905 - 1915), and the discovery of the structure of DNA by Watson, Crick, Franklin, and Wilkins (1953). These discoveries fundamentally changed humanity's understanding of the natural world. Try the Biology Quiz for life science, or challenge yourself with the Anatomy Quiz for human body science.

Modern science is increasingly interdisciplinary - Quantum mechanics and biology merge in quantum biology; computer science and biology merge in bioinformatics; chemistry and physics combine in materials science. The Large Hadron Collider at CERN in Switzerland is the world's largest scientific instrument, used to study the fundamental particles of the universe. The James Webb Space Telescope, launched in 2021, is revealing the earliest light of the universe. Science continues to expand the frontiers of human knowledge at an accelerating pace.
