Hi All(adsbygoogle = window.adsbygoogle || []).push({});

I am reading the following interesting book:

https://www.amazon.com/Einsteins-Mistakes-Human-Failings-Genius/dp/0393337685

In it he makes the claim Einsteins proof of E=MC^2 had errors. They were fixed (not by Einstein - but by Von-Lau in 1911 using Minkowski's tensor formalism) - but, he claims, even now correct proofs are not usually given.

I am scratching my head about that one.

The proof I know comes from Landau and is almost trivial - you write down the only reasonable relativistic Lagrangian for a free particle ∫m*dt where t is the proper time. You then apply Noether - its simple.

So what gives - is there something wrong with the above or is that dead simple proof not often given? If not - its a shame - its so easy and beautiful - and you would have to ask - why?

Thanksa

Bill
