CLASSICAL MECHANICS



'' Philosophiae Naturalis Principia Mathematica ''



In formulating his physical theories, Newton had developed a field of mathematics known as Calculus .

SPECIAL THEORY OF RELATIVITY



''On the Electrodynamics of Moving Bodies''


Description: Special relativity, developed in 1905 , only considers observers in Inertial Reference Frame s which are in uniform motion with respect to each other. Einstein's paper that year was called "''On the Electrodynamics of Moving Bodies''". While developing this theory, Einstein wrote to Mileva (his wife) about "our work on relative motion". This paper introduced the special theory of relativity, a theory of time, distance, mass and energy. The theory postulates that the Speed Of Light in vacuum will be the same for these observers. Special relativity solved the puzzle that had been apparent since the Michelson-Morley Experiment , which had failed to show that light waves were travelling through any Medium (other known waves travelled through media - such as water or air). It had been suggested that light waves actually did not travel through any medium: the speed of light was thus fixed, and not relative to the movement of the observer. This was impossible under Newtonian classical mechanics however, and Einstein provided a new system which allowed for this.

QUANTUM THEORY


''On the Law of Distribution of Energy in the Normal Spectrum''


Description: In Physics , the intensity spectrum of Electromagnetic Radiation from a Black Body at temperature ''T'' is given by the '''Planck's law of black body radiation''':

:I(
u) d
u d\Omega= rac{2h
u^{3}}{c^2} rac{1}{\exp\left( rac{h
u}{kT} ight)-1}d
u d\Omega

where:
:ν is the frequency
I

h

c

k


Max Planck originally produced this law in 1900 (published in 1901 ) in an attempt to interpolate between the Rayleigh-Jeans Law (which worked at long Wavelength s) and Wien's Law (which worked at short wavelengths). He found that the above function fit the data for all wavelengths remarkably well.

This paper is considered to be the beginning of Quantum Theory .
