The fine structure constant alpha=1/137.03... is really a taboo subject. Go to wikipedia and look at the entry "Theory of everything": there is not a word about the need to explain alpha. Go to the wikipedia article "List of unsolved problems in physics": the same. Yes, the prejudice is really strong: "If you think about alpha, you are not serious."
And that is the exact opposite of what Feynman said: "all good theoretical physicists put this number up on their wall and worry about it".
Do you know anybody who worries about the number? Search the internet; you will find nobody who does. Ergo: we have no good theoretical physicists at present!
