The discovery has been called monumental because it appears to confirm the existence of the Higgs field, which is pivotal to the Standard Model and other …

The Four Fundamental Forces of Nature

The Four Fundamental Forces of Nature are Gravitational force, Weak Nuclear force, Electromagnetic force and Strong Nuclear force. The weak and strong forces are effective only over a very short range and dominate only at the level of subatomic particles. Gravity and Electromagnetic force have infinite range. Let’s see each of them …

Classical Mechanics vs Quantum Mechanics

In this universe there are huge objects like planets and stars. There are also sub-atomic particles like protons and neutrons. You may note that at sub-atomic sizes, the wave nature of particles cannot be neglected and that the particles move at very high speeds. Which theory of Physics explains satisfactorily …

The Big Bang Theory
