Do you mean making simplifying assumptions to make a problem tractable? Of course it’s still going on. It has to be, otherwise you just cannot do anything.

> Assume the penguin's beak is a cone

It is impossible to consider the true shape of a penguin’s beak for several reasons:

- you’d need to go all the way down to the electron clouds of the atoms of the beak, at which point the very concept of shape is shaky

- every penguin has a different beak so even if you describe perfectly one of them, it does not necessarily make your calculation more realistic in general.

There is a spectrum of approximations one can make, but a cone is a sensible shape at a first order. It’s also simple enough that students can actually do it without years of experience and very advanced tools.

What do you think they should do instead?

Bet you’re fun at parties as they say.

I totally understand why simplifying assumptions are helpful in modelling and definitely don’t need you to explain that. It also is a bit ridiculous if you think literally about it which makes it something that is fun to laugh about as here.

Yes, sure, I get the jokes. I just found it puzzling that someone would think it stopped.

And I don’t talk about work at parties anyway :)

But nobody in this thread thought it (simplifying assumptions) stopped. You seem to be making an assumption that someone thought that and then posting long explanations that nobody asked for. I read the "P.S." of grand-grand-parent comment as good humor. Nothing there implied that they really thought that simplifying assumptions would/should stop.

Imagine a world where every bit of humor is interpreted literally and then refuted pedantically! What kind of a world would that be?
