full_question: One way to find the heat kernel involves taking the Fourier transforms of both sides of the heat equation and applying a formula named for this man which relates the coefficients of Fourier series to the corresponding coefficients of the Fourier transform. The time independent Klein-Gordon equation is effectively the screened version of an equation named for this man. Canonical coordinates must satisfy a binary operation named for this man which, like an operation named for Lagrange, for qi and pj equals the Kronecker delta of i and j. A property named for this man is negative in auxetic materials, which become thicker when stretched. This man tried to defend corpuscular theory by correctly showing that if light was a wave, there would be a spot of light would appear in circular shadows. This man’s equation is a generalization of another elliptical differential equation whose solutions are the harmonics. For 10 points, name this mathematician whose “bracket” is the classical analogue of the commutator, and names the inhomogeneous version of Laplace’s equation.
