Physics & Cosmos

Cosmos, in general, relates to the structure and nature of the universe, and the nature of “the universe” relates to human systems of seeing, our ways of thinking and perception, and what can be seen, literally and figuratively, by humans in general. It is not only about the cosmos, it is about who we are and where we are going as a species.

How Old is the Universe?

How Old is the Universe? (All Calculations so far)

A Bible-based assumption of a few thousand years was made by Isaac Newton. Einstein believed in a World that was steady-state, ageless. Since then, somewhere in the centre, data obtained from the Universe places the probable response. First Ingredient: Quantum mechanics    In the early 20th century, it was realized that the stability of atomic …

Why Strings theory

Why String theory?

Once special relativity was on the firm observational and theoretical footing, it was appreciated that the Schrödinger equation of quantum mechanics was not Lorentz invariant, therefore quantum mechanics as it was so successfully developed in the 1920s was not a reliable description of nature when the system contained particles that would move at or near …

classical physics vs quantum

Classical Physics vs Quantum Physics- The major Difference

What is the difference between classical physics and quantum physics? Physics that studies and explains the phenomena that occur in the domain of atoms, their nuclei, and elementary particles are called quantum; and the basic mathematical theory that explains the movements and relationships in this field is called quantum mechanics. However, it should not be …

third law of thermodynamics

Third Law of Thermodynamics- Absolute zero, Cryogenics, Adiabatic Demagnetization

In this article we will be talking about third law of Thermodynamics: Absolute zero, Cryogenics, Adiabatic demagnetization. Change of properties. Applications. Microscopic foundations of thermodynamics. The second principle suggests that an absolute temperature scale with absolute temperature zero occurs. The Third Law of Thermodynamics states that no procedure consisting of a finite number of steps can reach absolute …

Does Milky way contain Dark Matter?

What is Dark matter? Dark matter is a major component of Cosmology and Astrophysics. In the first case, the cosmological models of galactic evolution are based on this dark matter that does not emit or block light. Since it is assumed that it constitutes 85% of the total matter, the models are based on this …

particle physics standard model

Particle Physics Standard Model

What is the Standard Model of Particle Physics? A theory explaining the relationships between known fundamental interactions between elementary particles that make up all matter is the standard model of particle physics. It is a quantum field theory that is consistent with quantum mechanics and special relativity that was developed between 1970 and 1973. Nearly …
