A clarification

I have added a footnote to my Twin Paradox page (see link in sidebar) pointing out that among those who have correctly understood the paradox are mathematician Jeff Weeks, physicist Richard Wolfson and science writer Stan Gibilisco.

All note that the paradox is resolved only by General Relativity, which Einstein promulgated a decade after his first relativity papers. Curiously, Einstein seems never to have directly conceded that his groundbreaking "special" theory contained a logical contradiction.
