  • Musical synthesizers.

    Historically it is a hobby that's had a high financial barrier to entry.

    But the past decade has had a huge flourish of affordable and unique synthesizers and related musical equipment show up on the market. A lot of this stuff can be a TON of fun regardless of your musical knowledge/skill level. A few days on YouTube and a hundred bucks and beginners can be making their own music, with or without a computer with audio software.

    It starts simple, and can go to endless depths of creativity.

  • The utility of Laplace transforms in regards to differential systems.

    In engineering school you learn to analyze passive DC circuits early on using not much more than ohms law and Thevenin's Theoram. This shit can be taught to elementary schoolers.

    Then a little while later, you learn how to do non-finear differential equations to help work complex systems, whether it's electrical, mechanical, thermal, hydrolic, etc. This shit is no walk in the park.

    Then Laplace transforms/identities come along and let you turn non-linear problems in time-based space, into much simpler problems in frequency-based space. Shit blows your mind.

    THEN a mafacka comes along and teaches you that these tools can be used to turn complex differential system problems (electrical, mechanical, thermal, hydrolic, etc) into simple DC circuits you can analyze/solve in frequency-based space, then convert back into time-based space for the answers.

    I know this is super applied calculus shit, but I always love that sweet spot where all the high-concept math finally hits the pavement.

  • Weird. I graduated for engineering in 2017 and the majority of my teachers were completely detached from the real world applications, unreasonably strict, uncaring, and ridiculously stringent. It was supposed to be a "good" school. It was just super difficult.
