== 1912 ==
{{attachment:1_2.png||align="middle"}} '''Cosmic Rays Discovery'''<
> Austrian physicist Victor F. Hess discovers cosmic rays in a series of ascents in a hot-air balloon while looking for the source of the ionization radiation observed in the ground and in the atmosphere. His highest ascent was at 5.3 km of altitude. In 1936 he won the Nobel Prize for this discovery.<

{{attachment:21.png||align="middle"}} '''First Observation of a Muon'''<
> The evidence of the existence of muons was brought forward by Paul Kunze in a Wilson cloud chamber exposed to cosmic rays. Although at the time it was not know what particle produced the evidence. It was classified as a product of a nuclear explosion.<

{{attachment:2.png||align="middle"}} '''Muon Definitive Discovery'''<
> American physicist Carl D. Anderson and his graduate student Seth Neddermeyer discovered the existence of muon particles. The observations came from muons produced by cosmic rays. The muon was the first subatomic particle to be discoved.<
