Albert Einstein – theory of relativity
(energy is = to mass multiplied by the speed of light squared)
Galileo Galilei – studied the behavior of falling bodies and experimented with pendulums
Isaac Newton – formulated the laws of motion, gravity, discovered the nature and composition of light
Aristotle – believed that all things are made of four elements: earth, air, fire, and water
Johannes Kepler – discovered that planets follow an elliptical orbit which can be calculated for use in flight paths
and spacecraft today
Count Rumford - investigated heat energy
James P. Joule – investigated heat energy
James Maxwell – electromagnetism, general equations on the electromagnetic field, contributed to the . .
kinetic theory of gases
Benjamin Franklin – studied electricity, did a kite experiment to study lightning, invented the lightning rod
Michael Faraday – studied electricity, magnets can be used to create a current, electric generator
Thomas Young – studied light, demonstrated the interference of light, wave theory of light
Agustin Fresnel – studied light
W. Roentgen – X-rays
Henri Berequel – radioactivity
Max Planck – quantum theory (quantum mechanics)
Mechanics – study of motion
Heat – study of temperature and its effects on matter
Wave Motion – study of transfer of energy by means of a periodic disturbance through a medium
Optics – study of the nature of light
Electricity and Magnetism – electric and magnetic fields and their interaction
Nuclear Physics – study of radioactivity and the interconvertability of matter and energy
Measurement – process of finding out how many times a chosen quantity is contained in a given standard unit quantity
o
