Dale Husemoller
Dale Husemöller (also spelled Husemoller) is an American mathematician specializing in algebraic topology and homological algebra who is known for his books on fibre bundles, elliptic curves, and, in collaboration with John Milnor, symmetric bilinear forms. Life and career Husemöller was born in 1933 in Austin, Minnesota, USA. He earned his BA in mathematics at the University of Minnesota (December 1952). He began his graduate career there as a physicist, transferring to Harvard University in 1953. There, he switched from physics to the PhD program in mathematics. He completed his Ph.D. at Harvard University in 1959. His doctoral supervisor was Lars Ahlfors. His dissertation topic was ''Mappings, Automorphisms and Coverings of Riemann Surfaces''. After the PhD, he served on the faculty of the University of Rochester (1958-59) and the Pennsylvania State University (1959 to 1961). There his interests shifted to topology. He spent most of his career at Haverford College from ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

5 (five) is a number, numeral and digit. It is the natural number, and cardinal number, following 4 and preceding 6, and is a prime number. It has attained significance throughout history in part because typical humans have five digits on each hand. In mathematics 5 is the third smallest prime number, and the second super-prime. It is the first safe prime, the first good prime, the first balanced prime, and the first of three known Wilson primes. Five is the second Fermat prime and the third Mersenne prime exponent, as well as the third Catalan number, and the third Sophie Germain prime. Notably, 5 is equal to the sum of the ''only'' consecutive primes, 2 + 3, and is the only number that is part of more than one pair of twin primes, ( 3, 5) and (5, 7). It is also a sexy prime with the fifth prime number and first prime repunit, 11. Five is the third factorial prime, an alternating factorial, and an Eisenstein prime with no imaginary part and real part of the form 3p ...
