Who was the jerk who deleted the medal theft paragraph? It is news, all over the papers in USA. Nobel medals are pure gold and also precious for their symbolic value. The fact that he donted his medal for post-mortem public display and the museum was morons to display such a rare and valuable object without true security is notable and revelant. Restoration is thus demanded!

Proposed: altering existing photo link to Lawrence images at the Emilio Segrè Visual Archives
I'd like to propose changing the photo link from
[1] to
[2] as this latter link shows all of the Lawrence images at ESVA. In page History, see change made 1/25/2010.
Sure, looks good, makes sense.

"1939 for his invention of the cyclotron atom-smasher" - is "atom smasher" colloquial? I've always thought it is, and if that is the case, it is probably redundant.
"and two years later became the youngest full professor at the University of California" - "becoming the youngest full professor there two years later."
"high-energy particles and pondered how to make the accelerator more compact. He created a circular accelerating chamber" - "high-energy particles. Contemplating how to make the accelerator more compact..."

No, he stumbled across 80-tons of magnet. It was used by the Navy for something. I'll have to expand this, but haven't got the book on hand here. Please give me a few days.

Something of a contradiction between the paragraph beginning "Through his increasingly..." and the previous one. Perhaps "this did not translate immediately into scientific discovery" would make more sense?

"Lawrence had already thought about the problem of uranium enrichment, for only the uranium-235 isotope is fissile." - "Lawrence had already thought about the problem of uranium enrichment, for only the uranium-235 isotope will undergo the fission reaction necessary to create a bomb" - or something like that

No, that is not correct. It wasn't a proposed way; it was already known to work. But it only produced small quantities, and could not be used on an industrial scale.
