Einstein's Legacy? |
I recently learned of Einstein's annus mirabilis, 1905, during which he
published five breakthrough papers, three of which won Nobel Prizes. He
published one paper a month between March and June 1905, covering Brownian
motion, the photoelectric effect, special relativity and general
relativity, not necessarily in that order. Finally, in September 1905, he
published E=mc^2 in a letter.
However, I most often hear Einstein's name used in discussion of his famous
summation convention, where a repeated index implies a sum over that index.
Does anybody know, in which of the 1905 papers did he introduce the
summation convention?

He introduced it in the context of general relativity in 1916

Is somebody world-class slow on the uptake?

It was much easier in those days - all that stuff hadn't been
discovered yet.

Ahh... finally!

Papers don't "win" Nobel Prizes.
