| By 1936 Anderson
had made yet another discovery in his cloud chamber - a completely new
particle, seemingly identical to the electron but 200 times as heavy. |
|
| This particle is
produced in the cosmic radiation that continually bombards the earth but
lives for only about a millionth of a second, decaying by a radioactive decay
process. |
|
| It seems to have
no use at all in the Universe - an idea beautifully expressed by Isidore Rabi
with the question ‘Who ordered that?’ |
|
| This is still a
challenging question as I hope will become apparent later. |
