Enrico Fermi on Einstein's theory of special relativity

Yesterday I came across some fantastic notes by a young Enrico Fermi on Einstein's special relativity, which were included in "Asimmetrie", an outreach magazine issued by the Italian Institute for Nuclear Physics (INFN). After some search I found an English translation (by Robert Jantzen, I think).

The reading is really mind-blowing (well, at least for me...) and even more so considering Fermi was 21 at the time...

Enjoy!

Apparently, there are no pictures of Fermi and Einstein together, so I turned down to this one...
