THE QUICK HISTORY OF COSMIC RAY MAN THE BIRTH OF AN EXTRAORDINARY PARTICLE… Wilson suspected the cause of the residue conductivity of the atmosphere might be condensation tracks on the nuclei-ions.

7. THE REBIRTH OF COSMIC RAY MAN MAN

8. THE MUON… THE REBIRTH OF COSMIC RAY MAN!

9. By the time Cosmic Ray Man reaches the Earths surface, there are mostly muons and electrons left…about 5/6 and about 1/6 (respectively). So the higher the primary energy, the more muons and electrons are on the ground.
