What you’re so passionate about, that you can give a lecture without preparing?
- Timekeeping, the practical parts
- nuclear weapon, design and practice
- The educational benefits of doing very silly things
- brainstorming properly 101, learning not to interrupt other people
- brainstorming properly 201, “yes, and” isn’t just for improv comedians.
- basic principles of rocket engine design
- ADHD and learning to love the fact you just got distracted and remembered the joke about riding bikes
- artistic hydrodynamics, why watching wax cool is nothing like watching paint dry
- fire, from kindling to fuel air mixtures
- DevOps, ITIL, and philosophy, a.k.a. why DevOps should be a goal not someone’s job description
I’m probably forgetting lots, but that’s sort of to be expected, since I can latch on and care too much about anything that catches my fancy, leading to deep dives into research that leave my life littered with general knowledge and trivia that often has people asking me “how do you know so much?” …
I effectively collect things I care about enough to learn more than An average person and have also learned how to weave a half decent ad lib lecture, which leaves me with far too many things about which which I could “ give a lecture without prepping”.
:thumbsup:
curious about the bike joke
Multi-language websites and blogs. I made an internal tool to manage them and turn it into a SaaS last here: https://www.polyblog.io
I could give a long lecture on how to use Virtualbox. Spinning up new VMs is now second nature and I could do it with my eyes closed.
Astronomy and space exploration.
Same thing here. Only hobby exposure, but the topic I could fill the most hours with.
Minerals and jewels perhaps, although it has been a while. Was a hobby by me as a child to collect them. Partially motivated by the belief they would be valuable (they were not).
Greek mythology was fascinating to me as a child, although I have forgotten most of it again. Still could maybe fill an hour.
Perhaps also painting and modeling, but this would only be very shallow knowledge. There is quite a bit of formal knowledge about typography for example that really helps you design a aesthetically pleasing layout, but I didn't get to it yet.
U-boat design and their sensors. Don't know why, but I always found them fascinating. Crazy to actually use them, but fascinating. A bit of an exception because I usually find military tech to be utterly boring.
Software too of course, although I think it is a difficult topic to present. Howtos for simple electronics and in general actors/sensors would be my choice.
Aikido could certainly fill another hour. Really liked it but sadly gave it up shortly after I finished my studies. Not a good topic for a purely theoretical treatise.
Basics of sailing and different types of rigging.
And fish. Also how to cook them.
What specific about it? Planet movements? NASA missions? Black holes?
I've been an astronomy and space enthusiast for over four decades and ended up interested in pretty much everything you mention, and more.
Blacksmithing, mead making.
data processing with spark.
