Why The Higgs Is A Bad Ballerina
The Higgs boson, whose discovery was confirmed by CERN on July 4th to the exacting 5-sigma level required in particle physics (meaning that the probability that the bulge in the data indicating a

Re: How does one find the sum of series by multiplying through
Use the identity cos(a)=(exp(ia)+exp(-ia))/2 which transforms the sum into geometric series.
