Christmas tree search

There were two blondes who went deep into the frozen woods searching for a Christmas tree.
After hours of subzero temperatures and a few close calls with hungry wolves, one blonde turned to the other and said, "I'm chopping down the next tree I see. I don't care whether it's decorated or not!"

Edward Charles Titchmarsh

Died 18 Jan 1963 at age 63 (born 1 Jun 1899).English mathematician whose contributions to analysis placed him in the forefront of his profession. His contributions helped resolve the differences between the general theory of quantum mechanics and the methods used to solve particular problems in quantum theory. All Titchmarsh's work is in analysis. His early studies were on Fourier series, Fourier integrals, functions of a complex variable, integral equations and the Riemann zeta function. From 1939, Titchmarsh concentrated on the theory of series expansions of eigenfunctions of differential equations, work which helped to resolve problems in quantum mechanics. His work on this topic occupied him for the last 25 years of his life.
