This is what happens when you divide by zero on a 1940s water computer

"This weeks prime minister" love it XD

"Divide by zero" in electrical engineering tends to have some exciting results. Someone at work forgot the earth clamps (just some wires) on a 33 000V system. When power was switched on, ohms law was enacted: current=volts/ohms. Volts being 33 000V and ohms being far into the 0.0s. The result was that the cables ceased to exist.

Interesting fact the term trickle down economics was coined by a comedian making fun of the idea. As for this very expensive economic endeavour all we get is a trickle.

Terry Pratchett parodied this in one of his books, Making Money, and it was hilarious. It so perfectly modeled the economy that evaporation made money disappear.

With some amount of practice, it is possible juggle eggs. With even more practice, it is theoretically possible to talk about supply and demand. But doing both at the same time? pure madness

My compliments to juggling while remembering the script while also not accidentally splatting an egg on yourself

So the "Divide by Zero error" in calculators, is just a built in security feature so the calculator dosen't break, and spills electricity everywhere? 7:37

Ah that's why they're called liquidities.

"They're not particularly leak proof." I feel like that's a metaphor for people that hide their money.

2:26 the leak is just money that’s lost in couch cushions, no worries.

So what I learned from this simulation is that if nearly everybody lives paycheck to paycheck (zero propensity to save) the economy will look like it’s booming, when actuality it’s in a fatal error state that produces good-looking upward metrics until you realize a ton of money is unaccounted for (spilled out) and nothing is actually being allocated properly or flowing correctly

Seeing the water computer's import-export side arm reminded me of how, in the late 1960s and early 70s, politics was obsessed with "balance of trade" figures. For some reason, that hardly ever gets mentioned these days.

You're becoming quite the showman! Great video as always. PS: My dog likes the sound of your voice for some reason

I loved seeing the equations side-by-side!

i love how Infinity (an overflow error for digital computers) results in a literal OVERFLOW of water. you got a memory leak

THE GLOOPER IS REAL – that's incredible, I assumed that it was one of Sir Terry's wild flights of fantasy rather than based in any kind of reality. In fact, this idea is so wild that I'm still not 100% convinced that you haven't released your 1st April video a couple of months early by mistake 😆 Definitely one of the best videos you've made, not just impeccably researched and presented, but all the greater for your judicious use of jokes, juggling and jestering – I love a bit of political snark in an explainer video!

Atomic Frontier: Can I try and find out if your unique, historic, priceless water computer can divide by zero? Cambridge University: No.

Your bedroom built equipment depicting a leaking economy is accurate. Always enjoy your videos, keep up the hard work!

It never ceases to amaze me just how much of The Diskworld series the late, great Terry Pratchett nicked from real life.
