Did you have a teacher that sparked epiphanies?

dougw

Did you ever have a teacher who presented material in a way that led to you have an epiphany, where the concept just clicked?

  • Like realizing that the derivative of a waveform at a point is simply the slope of the waveform at that point
  • Or understanding that the integral of the waveform is simply the area under the curve
  • Or how negative feedback makes an amplifier predictable
  • Or how a dielectric affects capacitance

What concepts do we now take for granted that when you first came across them, they were magic?

    Yes - his name was Mr Woolard, he taught maths and rugby football while I was in the sixth form studying 'A' levels. Up until then I'd been pretty dumb at maths. With his teaching lots of things suddenly…

    One surprisingly useful concept that clicked after just being mentioned in an off-hand way was dimensional analysis, where one could solve problems or at least do a sanity check on answers just by figuring…

    lol no. Most of the entire time, Teachers, peers and anyone one else is telling me Idea X is a dumb idea, impossible, or without purpose.

    For example: made an IoT coffee machine, and IoT refrigerator in 2000. Professor was like this is some of the stupidest stuff I have ever seen.
    you only pass because it does show you know how to build circuits. 20+ years later, everything is on the internet.

    The epiphany is perhaps no one knows what the future will bring. You cant trust other peoples opinions.

    to be fair, I've done the same thing. in 2002 or so, I told some kid printing in 3 dimensions would be a tedious and error prone activity, and I couldn't imagine it ever gaining ground in the consumer electronics field.

    I guess it takes different amounts of time for the penny to drop with different people. Freezer IoT has always been useful.

    In 1997 I solved a big problem for a food company by connecting a bunch of walk-in freezers to a server (IoT and cloud computing of the day) The system logged temperatures and if any went out of bounds the system would start phoning people to go and troubleshoot the problem. (that was my first big speech synthesis project) If someone left a freezer door ajar, or there was some failure, it could cause an expensive amount of food spoilage.
