Some of us aren't so sad as to allow alerts from social media to distract us from life.

You must be anti-Newton then because Einstein was less wrong. Flat earth can be an appropriate level of science though, obviously, not as accurate as QED which itself is wrong.

Nice to read about an actual epicentre for a change. I got bored hearing about that secret lab under the market in Wuhan.

I always ask LLMs how do epidemics grow exponentially and they always respond with a dumb answer just like most people.

Why relativity? And why turbulence?

The ballistic equation. Rayleigh-Benard convection. Stress analysis of giant structures sagging under their own weight. All analysed using a uniform vertical gravity field implying that the Earth is flat.

Pseudo science. You mean like epidemics grow exponentially?

I've seen research that has failed critically because they assumed that the random variable was normally distributed.

Perhaps in tribute to a famous Belgian that was removed from the Index of history? (General knowledge crossword clue)

Oops, should have said exponential growth. Obviously exponential decay is natural.

I hope it includes the word "exponential" and says that it has nothing to do with epidemiology whilst referencing Farr (1840), Kermack-McKendrick(1927), etc. etc.

Epidemic The card game

I've seen several stochastic epidemic models that break the laws of Maths. The bridge between the two subjects is probability theory. You can use it to calculate the odds that an epidemic will grow exponentially.

Good luck. I hope you never say an epidemic grows exponentially. Although that was debunked in 1840, 1927, ... lots of people still insist on telling everyone that they failed basic Maths.

Then you should get back to Turin quickly before the local beer kills you. (I lived opposite the XXXX brewery, they used to make mango flavour beer)

During the mask mandate I wore a mask that I'd made from gauze. It had the same effectiveness as most others and the advantage that I needn't carry a knife to go with a surgical mask designed to stop pressurised bodily fluids from entering the nose and mouth when the wearer stabbed someone.

And yet there are millions of Aussies, mainly on the coast. I once worked with them on a site with 4 different species of snake including the most deadly and an official snake catcher. We also had platypuses, Asian geckos (used to leave chalky white turds on my desk) and, presumably, spiders.

The first question that I asked Grok was how epidemics grow exponentially. So it told me. It should have told me not to be so silly and provided references back to 1840. LLMs are as ignorant as the average person. i.e. the weights are trained by "common knowledge"
