founded the Heliocentric theory of the solar system in which the Earth rotated around the sun
mathematically predicted movement of planets. Supported Copernicus theory of heliocentric solar system.
used a refracting telescope to show the Earth revolves around the sun--the Heliocentric theory
Snell's law defined the angle of refraction of light as it passed through a substance
measured distance to stars, defined the law of elasticity and alternating principle of gravity.
defined the Three Laws of Motion and gravity. Invented Calculus and defined how sunlight was made up of several colors
invented bifocal glasses, the lightening rod and theorized that the storm lightening was the same nature as the static electricity developed in his lab
stated Avogado's law which says that an equal number of molecules of gas exist in containers of the same volume, pressure and temperature. Called the 'Ideal Gas Law'
Ampere's Law. Defined the AMP which was a fore-runner of the electron concept.
defined Joule's law which is the relationship between heat, current flow and resistance
defined 'Ohm's Law' which states that the resistance of a conductor is inversely proportional to the voltage
defined the Doppler effect in which the received frequency changes with the movement of the source
defined the temperature absolute 0 null point at which there is no molecular movement at -273 degrees Celsius. This unit is named Kelvin
defined the unit of work measurement, the Watt. For example, an average person working in a day is the power/work of 85 watts
defined electricity can be transmitted in electromagnetic waves. Hertz unit standard. Also, by accident discovered the photoelectric effect
Developed alternating current machines which were more efficient than direct current machines. He also developed the first fluorescent lights. Tesla did not get along with his early manager, Thomas Edison, so he did his inventions for Westinghouse
defined light's particle nature, the photon, and the 'Theory of Relativity'
