Lemaitre was also a first-rate geometer. He wrote a paper on quaternions and elliptic geometry (geodesics on a sphere) that was published with a Latin abstract in a journal of the Pontifical Society of the Vatican. My library didn't have a copy, and so that was probably the only time in my life that I had to correspond with the Vatican to get a copy :-) |
