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

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.

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.

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.

Will they be telling you next how to write ODEs? That would be lyrical.

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"

If you want something more modern than the 1980s then there is the Cochrane Review which found that there was no decent evidence that they worked.

Here's a very simple model although the card game implementation is probably better to teach, the NetLogo gets a bit complicated but shows that the reproduction rate averages
to that of the standard SIR model.
