- The point is that if what Pais says about Poincare's 1908 lectures
- in Goettingen is true, then Poincare did not understand the full
- implications of the equations he wrote in his 1905 paper, and
- Einstein expressed in his 1905 paper a much fuller understanding

- To make a statement like this is not to be giving awards, which
- is not a question of fair-mindedness but what makes sense as
- history.
