Nuclear Fission Basics

Nuclear fission is said to have occurred when nucleus of an atom splits into several small fragments. In nuclear physics nuclear fission either occurs as a nuclear reaction or as a radioactive decay process in which nucleus of an atom splits into smaller and lighter nuclei. The fission process often produces free neutrons and photons (in the form of gamma rays), and releases a very large amount of energy even by the energetic standards of radioactive decay.

Solving physics problems

Lots of time students me how can they solve physics problems and they say that they are having difficulty in solving physics problems. So here I decided to address this issue. Now first of all I would say that do not be afraid of the subject as I say again and again physics to me is most basic of all sciences and you must find the subject interesting and give yourself reasons for studying it for me it was just what I wanted to study till my masters degree and now I like helping students understanding physics.

Top Known Scientist in Heat and Thermodynamics Field

James Prescott Joule (1818 – 1889)
•He was an English physicist and brewer, born in Salford, Lancashire.
•He received his early education at home
•He studied for sometime under John Dalton
•Joule studied the nature of heat, and discovered its relationship to mechanical work .
•His first major research was concerned with determining the quantity of heat produced by an electric current and, in 1840, Joule discovered a simple law connecting the current and resistance with the heat generated.
