Theory of Magnetism and Electromagnetic Induction
Ferromagnetic material has a special property – it can be magnetizing to create temporary magnetic domains. Every magnetic domain contains two atoms. When an electron moves from an atom to the next atom and stays there temporarily, the two atoms become a temporary…
Stellar Formation
Formation of stars Stars vary in their composition and may be divided into generations. The first generation of stars, which were primordial megastars, were extremely large and consisted mostly of helium and hydrogen. However, second and third- generation stars ha…

Fate of the Stars
Chandrasekhar worked out how big a star could be and still support itself against its own gravity after it had used up all its fuel. The idea was this: when the star becomes small, the matter particles get very near each other, and so according to the Pauli exclusio…
The Universe according to Alexander Friednman
Friedmann made two very simple assumptions about the Universe. Firstly, the Universe looks Identical in whichever direction we look. Next and the other, this would also be true if we were observing the Universe from Anywhere Else. From these two ideas alone Frie…
