    When doing a convolution of two curves in time, you flip one of them backwards.

    Our shit statistics teacher made it so complicated.

    And then one day, next semester, in a lab for signals class, the TA casually said “flip one, so they both start at zero seconds” and half the class started convulsing as an entire semester worth of misunderstood math magically snapped into place.

    Lots of engineering teachers, have no business being teachers.

        It depends on how you look at it. Perhaps that low point was just the first evidence of an increase in your life’s amplitude.
