“Joe’s scientific life is defined by these significant near misses… He was Shackleton many times, almost the first: almost the first to see the big bang, almost the first to patent the laser, almost the first to detect gravitational waves. Famous for nearly getting there.”

“An idea sparked in the 1960s, a thought experiment, an amusing haiku, is now a thing of metal and glass.”

“I don't believe that math and nature respond to democracy. Just because very clever people have rejected the role of the infinite, their collective opinions, however weighty, won't persuade mother nature to alter her ways. Nature is never wrong.”
