Great Scientific Discoveries & Inventions — Timeline of Key Events

YearEvent
1687Newton’s Laws of Motion & Gravity. Isaac Newton explained motion and gravity in his “Principia”, laying the foundation of classical physics.
1796The first vaccine. Edward Jenner developed the smallpox vaccine, beginning the science of immunisation that has since saved millions of lives.
1831Electromagnetic induction. Michael Faraday discovered how magnetism can generate electricity — the principle behind every generator and electric motor.
1859Theory of Evolution. Charles Darwin published “On the Origin of Species”, explaining evolution by natural selection.
1869The Periodic Table. Dmitri Mendeleev arranged the elements by their properties, even predicting elements not yet discovered.
1905Einstein’s theory of relativity. Albert Einstein transformed our understanding of space, time and energy (E = mc²).
1928Discovery of penicillin. Alexander Fleming discovered penicillin, the first antibiotic, revolutionising the treatment of infections.
1953Structure of DNA. Watson and Crick (using Rosalind Franklin’s X-ray images) described the double-helix structure of DNA, launching modern genetics.
