Another Great Physicist Passed Away

John Archibald Wheeler passed away today.

He was a living legend, had many fantastical ideas, taught and inspired generations of physicists including Richard Feynman and Kip Thorne.

I only knew him from his General Relativity book and his lectures about It-from-Bit.
For an example of the kind of things he imagined, check this passage from his wikipedia page:  ...theorizes experiments utilizing photons from distant locations in the universe, imaged using galaxy clusters as lenses, but which are detected using apparatus for quantum entanglement, thereby influencing history billions of years in the past.
