Milestones in Medical Science & Biology: - 1796 Edward Jenner: Introduced the first successful vaccine using cowpox virus to immunize against smallpox. - 1928 Alexander Fleming: Discovered penicillin from Penicillium chrysogenum mold, revolutionizing antibiotic treatment.
Physics & Astronomy Breakthroughs: - Nicolaus Copernicus (1473–1543): Renaissance astronomer who published 'De revolutionibus orbium coelestium' (1543), formulating the heliocentric model placing the Sun at the center of the solar system. - Albert Einstein (1879–1955): Formulated General Relativity (1915), describing gravity as the geometric curvature of spacetime. - Strong Nuclear Force: One of the four fundamental forces of nature (alongside gravity, electromagnetism, and weak nuclear force), responsible for binding protons and neutrons inside atomic nuclei.
