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.

Lorentz Transformation Equation & Derivation

Lorentz Transformation Equation & Derivation

Lorentz transformations, within the theory of special relativity, are a set of relationships that account for how the measurements of a physical magnitude obtained by two different observers are related. These relationships established the mathematical basis for Einstein’s theory of special relativity since the Lorentz transformations specify the type of space-time geometry required by Einstein’s …

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 …

dark matter existence reality

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 …

frequency of electromagnetic waves

Frequency of Electromagnetic Waves & their Frequencies

What is the Frequency of a Wave? Radio waves, microwaves, X-rays, infrared light, all these names describe, in fact, the same phenomenon: The electromagnetic waves. An electromagnetic field surrounds us always, in the same way that air surrounds us. Electromagnetic waves are disturbances in the electromagnetic field, as the sound is a disturbance of air …

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 …
