"He also helped to create an advanced physics course for M.I.T. freshmen with more than a rudimentary knowledge of the subject. He and Robert J. Kolenkow wrote a 2013 textbook for the course, “An Introduction to Mechanics.”"

I used Kleppner/Kolenkow's intro to mechanics (copyright 1973) in 1993 or so, not at MIT. Seems 2013 is referring to the 2nd edition: https://en.wikipedia.org/wiki/Daniel_Kleppner#Books Maybe the 1st edition was created for the "mechanics for masochists" MIT course.

"The first scientists to succeed, in 1995, were Eric Cornell, Wolfgang Ketterle and Carl Wieman at JILA (formerly known as the Joint Institute for Laboratory Astrophysics), a research institute in Colorado." incredible underhanded dig from the NYT (against the rest of the Boulder physics dept)
