ScientificContributors Ancient Greeks to Modern Day
Ancient Greeks • Hippocrates: first doctor, stated that diseases have natural causes. • Eratosthenes: estimated size of earth, advanced geometry. • Archimedes: catapult, Density formula, d=m/v • Pythagorus: A2+B2=C2 • Aristotle: developed many theories that led to modern day discoveries. • Domocrites: philosopher and mathematician, developed theory of atoms (atomos).
“Age of Genius” 1600’s/1700’s • Nicolaus Copernicus:sun centered solar system. • Leonardo DaVinci:Renaissance painter (the Mona Lisa) and an engineer, created designs for helicopters, tanks, solar power, bridges and human anatomy. • Galileo Galilei: improved telescope -many space discoveries. Tested theory of gravity. • Andreas Vesalius: Anatomy & Physiology, dissected stray cats & dogs, humans…made detailed drawings and books that later advanced surgery. • Antoine Lavoisier: “father of modern chemistry”, developed the law of conservation of matter. • Isaac Newton: laws of force & motion, white light is a mixture of all colors.
Robert Boyle: developed gas and pressure laws. “Age of Technology” 1800’s Dmitri Mendeleev: organized the modern periodic table Carolus Linnaeus: developed the classification system for plants and animals Robert Hooke: Biology, used simple microscopes to develop cell model and cell theory. John Dalton: Developed the atomic theory. Michael Faraday: did the groundwork for the age of electricity amd developed first electric motor. Charles Darwin: Theory of evolution.
Gregor Mendel: laws of heredity, recessive and dominant genes. • Alfred Nobel: Invented dynamite (sand, nitroglycerin). Peace prize named for him. • Wilhelm Rontgen: discovered x-rays accidentally while experimenting with electricity. Shadow showed up on Barium treated piece of cardboard. • Thomas Edison: Famous inventor who created electrical devices (light bulb). First to use electricity. • William Burroughs: invented first calculator, 1885.
“age of technology” • Earnest Rutherford- physicist, discovered protons. Won Nobel prize for work on alpha, beta and gamma rays. • J.J. Thompson-1906 Nobel prize winner in physics for his research on the discharge of electricity in gases (cathode tube experiment)-charge of electrons • Alexander Graham Bell- changed communication with development of telephone.
“Modern Science” 1900-present • Albert Einstein - German born, many inventions and Theory of Relativity: E=mc2 • Daniel Hale Williams- First African American to win Nobel Peace Prize in Medicine. He performed the first of many successful heart surgeries. • Marie Curie- radioactive experiments, 1st woman to win Nobel Peace prize • James Hillier - electron scan microscope: magnification of 7000 x. • Lewis Parker - combined transfer of sound and light information- first TV. First TV • Herb Boyer - father of genetic engineering (cloning) • Alexander Flemming - developed penicillin • Nikola Tesla - inventor, worked with magnetic fields and alternating current- AC/DC. • Niels Bohr- created quantum physics, developed Bohr model of atom.
Edwin Hubble- used doppler effect to prove that the universe is expanding (red shift) • Don Keck- invented fiber optics: transports more info at a faster rate • Enrico Fermi- father of nuclear age, developed nuclear fission(splitting of atom) • Alfred Wegener- developed concept of sea-floor spreading and Plate Tectonics • Stephen Hawking- proved Einstein’s theories, developed modern theories of cosmology (space) • Michio Kaku – theoretical physicist who cofounded superstring theory and help prove many of Einsteins’s ideas.
