-
William hypothesized that the Earth is a giant magnet.
-
Discovered mountains and craters on the moon of Venus, and the four largest satelites of Jupiter, Europa, Callisto, and Ganymede.
-
Discovered law of refraction.
-
Overturns a theory that heavier objects fall faster then lighter objects.
-
Discovered Hooke's law of elasticity.
-
Developed theory of gravitation.
-
Huygens suggested that light was a wave since it could be reflected and refracted. One problem was that light travels in straight lines and produced sharp shadows which meant it did not diffract.
-
State the 3 laws of motion.
-
Developed new methods of analytical mechanics.
-
Founded the science of thermodynamics.
-
1803 Dalton (in England) put forward a concept of an atom was generally accepted.
-
Discovered mechanical equivalent of heat.
-
Brownian motion: random moving of particles suspended in a fluid (a liquid or a gas) resulting from their collision by the fast-moving atoms or molecules in the gas or liquid.
-
The neutron was discovered by James Chadwick
-
Created alternating currents.
-
He proved Maxwell’s theory via a series of experiments and also discovered that the newly found waves behaved exactly like light but with ah much shorter wave length at this time.
-
He discovered something smaller than an atom, a particle with a minuscule mass and a negative charge.
-
Albert Einstein discovers the E=mc2 theory about energy equaling mass times the speed of light squared.
-
He found the positive nucleus in the atom that was surrounded by negative electrons, this was done through his well-known gold foil experiment.
