About Arts
Yesterday, my wife and I went to see the 1934 German film "Abschiedwalzer: Zwei Frauen um Chopin" (Japanese title "別れの曲"), which had been shown in Umeda, Osaka, to commemorate the 200th anniversary of Frédéric Chopin's birth. It rather comically depicted Chopin's love of his motherland Poland and two women, Constantia Gladkowska and George Sand.
About Physics
[In reply to materion's words, "Fundamental laws of physics are same everywhere. If the fine-structure constant is not same everywhere, this would mean that it's not a constant."] You're right, indeed, but Dirac would be pleased in heaven.
[From materion] I do not remember if Dirac expressed something about variation of fine-structure constant.
[To materion] I mean Dirac large numbers hypothesis. It does not refer to fine structure constant, but the gravitational "constant" was assumed to be inversely proportional to the age of the universe.
[From materion] Thanks for pointing out Dirac's large numbers hypothesis. Gravitational constant must be in some way interconnected with the fine-structure constant.
