Standard Particle Model of Quantum Mechanics is a mathematical model which explains the particle-wave nature of sub-atomic particles. This model proposed two major groups of elementary particles of matter, ie. Quarks and Leptons. The model also proposed elementary force carriers known as Gauge … [Read more...] about Standard Particle Model of Quantum Mechanics: Inside an Atom
Science and Technology Notes
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 … [Read more...] about Classical Mechanics vs Quantum Mechanics
The Big Bang Theory
Big Bang Theory is about the origin of the Universe. It suggests that about 1370 crore (13.7 billion) years ago, all matter and energy in the universe was concentrated in an area smaller than an atom. At this instant, matter, energy, space, and time were not existent. Then suddenly with a bang, … [Read more...] about The Big Bang Theory
