Matter is anything that has mass and takes space. But apart from the ‘normal’ matter, there are different other forms of hypothesized matter. A few examples include Dark Matter, Anti Matter and Negative Matter. You by now know that matter and energy are inter convertible; so there are Dark Energy, Anti Energy and Negative Energy […]

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 in detail. The […]
Fermions and Bosons : Particles Which Make The Universe
There are possibly only two classes of ‘particles’ in the universe – Fermions and Bosons. All elementary particles (Quarks, Leptons, Guage Bosons, Static Bosons etc.) will fall under either of these two. Not only elementary particles, but also composite particles like Baryons (Eg: Protons, Neutrons etc.) will also fall under this basic classification of all […]
Standard Particle Model of Quantum Mechanics: Inside an Atom
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 Bosons (responsible for the forces in nature) and one Higgs Boson. Standard […]
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 behavior of both? Classical […]
The Big Bang Theory
Big Bang Theory is about the origin of Universe. It suggests that about 1370 crore (13.7 billion) years ago, all matter and energy in the universe was concentrated into an area smaller than an atom. At this instant, matter, energy, space and time were not existent. Then suddenly with a bang, the Universe began to […]
