Ya got me there. The pair of you. 
Even if you don’t ordinarily do crossword puzzles, the odds are good that you’ll get a bang out of the one in tomorrow’s NY Times - their Sunday puzzle.
Hell, you might even break out in a smile.
Because when your country goes to war with another country, it’s the countries that are at war. The citizens of that other country don’t automatically lose all their legal rights. It could happen, if the legislature of your country passed a law to stip the citizens of the other country of their rights, but in the absence of such a law, the citizens of the other country still have legal rights.
International conventions don’t apply automatically domestically - they have to be implemented by domestic legislation. In the case of copyright, that means that the British Parliament had passed a copyright act to implement the Berne Convention. Unless the British Parliament had expressly amended its copyright laws during the war to strip German citizens of their legal rights under the act, then a German citizen could sue for copyright infringement, by instructing counsel to bring the action in the British courts. The fact that Britain and Germany were at war would not give a private publisher the right to break the British copyright act and infringe on the legal rights of a private German citizen.
So suppose a British publisher publishes Einstein’s works during WWI without his permission. Einstein could go to a neutral country, like Switzerland, that still had communications with Britain, and going through Swiss counsel, instruct counsel in Britain to bring an action to enforce his copyright.
I’ve looked over the evidence, as far as I know it, and I haven’t seen any evidence that his wife was responsible for any part of the theory. She was a fellow physics student, but Einstein discussed his work with all the students–as do many modern scientists.
Well, I guess you all missed the Sunday NY Times puzzle.
The observation (by 67 Down) was:
“The only reason for time is so that everything doesn’t happen at once.”
2 Down: Proposed by 67 Down: Theory of relativity.
82 Across: Famed statement by 67 Down: e = mc2 (The constructor couldn’t do a ², because the intersecting answer was Tea for 2.)
And 67 Down was: Albert Einstein
Forget the ², I just want to know if anything intersected with the ‘=’
Yes. The ‘m’ in “for time is so”.
