"They used physics to do it" is just a laughably pathetic motivation. Nobel hated "abstract wankery" or "intellectual masturbation" and wanted to promote results which benefitted the common man and society directly. This is incidentally also why there doesn't exist a Nobel prize in economics. The nobel prize comitte has since long abandoned Nobel's will in this matter and it is anyones guess what the order of magnitude of spin Nobel's corpse has accumulated.

How long? Wouldn't this just kind of suggest that criteria is simply different at this point? Maybe complex electronic devices didn't exist back then, so one can really only guess as to what he would think. Because he's been dead for a very long time...
The prize is named after the dude, he doesn't get to decide the rules of its award in perpetuity.
