The Limitations of Classical Physics
Light waves and other forms of electromagnetic waves travel through free space at the speed c = 3.0 x 108 m/s. The speed of light sets an upper limit for the speeds of particles, waves and the transmission of … Read More
Einstein’s Special Theory of Relativity
Einstein special theory of relativity is based on two assumptions:
- The principle of relativity: All the laws of physics have the same form in all inertial reference frames.
- The constancy of the speed of light: The speed of light in
Yukawa Meson Theory of Nuclear Forces
In 1935 Yukawa proposed in his paper that there exist a meson field, that is, a field that is different from the electromagnetic field, whose quanta, the mesons have a finite mass, which is coupled to protons and neutrons in … Read More
