mcnees, Physicist John Archibald Wheeler was born #OTD in 1911.
A titan of 20th century science, Wheeler introduced the S-Matrix; developed the first general theory of fission with Neils Bohr; coined many terms (”worm hole” and “it from bit”) and popularized others (“black hole”); and trained Feynman, Everett, Thorne, and a host of others.
