    Is e=mc2 a sexed equation?…Perhaps it is. Let us make the hypothesis that it is insofar as it privileges the speed of light over other speeds that are vitally necessary to us. What seems to me to indicate the possible sexed nature of the equation is not directly its uses by nuclear weapons, rather it is having privileged what goes the fastest.

    There's something elemental about the mathematics that fascinates me.

    Good lecturer.
    Fuzzy integer math, with sloppy operators.

    Oh, and reverse propagated asymmetric regauging.

    You put in the answer you want, and it figures out the corresponding problem.
    Fuzzy integers. Analogue integers. Take, say, 5. Some problems will be answered more easily if the value of "5" is allowed to vary stochastically within certain probabilistic limits. It is the purview of any competent mathematical AI to learn to compute with fuzzy integers. They make many problems more soluble.

    Also recursion. When "5" is allowed to be anywhere from 4.9999999999995 and 5.0000000000005, then 5.0000000000005 itself becomes fuzzy. Which opens up an entirely new universe of problems.

    Granular synthesis.

    In the Real World™, you have to deal with that. Floating-point math is approximate, not exact--what lurks out there after the LSD is terra incognita.

    Or... well, not quite exactly, but close enough.

    I use fuzzy integers all the time in mental arithmetic. It is also useful to know about the "whatever" operator.
    Sloppy operators are important too. Like when doing local accounting. The "sminus" operator works like subtraction but does not subtract quite all the subtrahend from the minuend. "Smadd" is similar in that it does not add quite all the addends to reach a (semi) final fuzziresult.

    One of the almost interesting features of fuzzy mathematics is that almost all formal systems can sometimes be shown to be nearly equivalent.
