"The talk will start with
asking a few puzzling questions about why sinusoids are "natural". The talk will start with the entire
genesis:
Fourier's observation and breakthrough series representation, unify frequency domain approaches, look at
how impulses are explained by hitting a baseball with a bat (and got Dirac some credibility in realistic
work), relate the landmark FFT algorithm to sorting a set of numbers,and why linear shift-invariant
systems are important, along with
convolution."
