Dr. Homi J Bhabha is a respected name in the field of theoretical research in Physics. In 1937 while at work in England he propounded what has come to be known as the Bhabha-Heitler cascade theory. This theory concerned the electron showers in cosmic rays which bombard the earth from all directions. To understand this theory it is important to understand a few simple facts that this theory touches
a) Cosmic Rays. These rays were discovered in 1912 by Victor Hess. This discovery came after he found that as he went up in a balloon with an electroscope, it discharged more rapidly. An electroscope is an instrument to detect the presence of electric charge. He was able to attribute these phenomena to a new source of radiation and subsequently won the Nobel Prize for Physics in 1937.
