I have for a long time been searching for applications of the philosophy of Wittgenstein, particularly later Wittgenstein, to physics. I believe I have found that application in the work of Peter Putnam, who, building on the philosophy of Sir Arthur Eddington, Everett (of Many Worlds fame), and John Wheeler, constructed, in his private musings, the beginnings of a verbal, syntactical representation theory for quantum physics.
There have been a couple of articles lately about Putnam, starting with this one in Nautilus less than a month ago.
He was a relatively unknown figure who might have been as famous as Wittgenstein himself if not for a meddling mother.
