Alpha Particles Nuclear Physics
758 wordsErnest Rutherford was born in New Zealand in 1871 as one of 12 children. It was Rutherford who first "split" an atom and who discovered the atomic "nucleus", a name that he invented. For this he is regarded as the greatest experimental physicist of his time. Rutherford was one of the first and most important researchers in nuclear physics. Soon after the discovery of radioactivity in 1986 by the French physicist Antoine Henri Becquerel, Rutherford discovered the three different types of radiatio...

Hydrogen Bomb Nuclear Fusion
2,740 wordsFusion reactions are inhibited by the electrical repulsive force that acts between two positively charged nuclei. For fusion to occur, the two nuclei must approach each other at high speed to overcome the electrical repulsion and attain a sufficiently small separation (less than one-trillionth of a centimeter) that the short-range strong nuclear force dominates. For the production of useful amounts of energy, a large number of nuclei must under go fusion: that is to say, a gas of fusing nuclei m...

Big Bang Theory 20 Th Century
3,306 wordsAlbert Einsteins theory Relativity Relativity Albert Einsteins theory of relativity has caused major revolutions in physics and astronomy during the 20 th century. It introduced to science the concept of relativity the notion that there is no absolute motion in the universe, only relative motion thus superseding the 200 -year-old theory of mechanics of Isaac Newton. Einstein showed that we reside not in the flat, Euclidean space and uniform, absolute time of everyday experience, but in another e...
