You brought back the wonderful memory of a presentation I went to in the early 1990s on wavelet transforms and using higher order systems of equations to combine Fourier and Laplace transforms into a workable and more complete description of complex waveforms in the ~real world. Once the underlying concept was grasped (very quickly; it isn't That much of a leap from either of the two inital systes), I got caught up in the math and wrapped my head around a 5-1/2 dimensional Hilbert space. Now there's something no drug I've ever even Heard of can match. Unhappily, the side-effect of the whole ~ordinary world being an insignificant flyspeck far off to one's side Can be a problem ... I had to come back down to avoid walking into walls and driving ~through concrete pillars.
