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.

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

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 …

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 …

Second Law of Thermodynamics-Entropy

Second Law of Thermodynamics- Entropy & Axiomatic definition, Microststes & Canonical interpretation

The Second Law of Thermodynamics provides for a precise description of a property called entropy. Entropy can be seen as a measure of how close a system is to equilibrium. It can also be seen as a measure of (spatial and thermal) disturbance. The second thermodynamics notes that the entropy, that is, an individual system’s …

Kepler's Laws on the Movement of the Planets

Kepler’s Laws on the Movement of the Planets

Astronomy was of interest to Kepler from an early age, but smallpox transferred in childhood hit the future scientist’s eyes hard and seriously limited him in his ability to independently conduct observations. However, interest in science has not been lost. While studying at the university in Tübingen, Kepler got acquainted with the heliocentric system of …
