Happy Birthday James Chadwick! http://www.nobelprize.org/nobel_prizes/physics/laureates/1935/chadwick-bio.html He won the Nobel Prize in Physics 1935 "for the discovery of the neutron" in 1932... without his discovery these amazing research in many areas of science and technology with neutrons would have not been possible for the past 80 years!

A short video about Chadwick and his discovery of the neutron: http://www.youtube.com/watch?v=ZK-yeuu_p9k

A great writeup about the discovery of the neutron by ANS, posted it here last year but it is worth repeating: http://ansnuclearcafe.org/2011/10/19/pioneers102011/
