Same here. The Laplace transform and it's consequences changed my life. I also took a class in college about some stochastic signal processing where I learned about Autocorrelation. The application was finding signals in very noisy environments. The professor who taught it was measuring electrical signals from the auditory system in rabbits. https://en.wikipedia.org/wiki/Autocorrelation https://en.wikipedia.org/wiki/Autocorrelation
