America is in crisis.

So it's a small relief that the rest of the world is actually getting remarkable stuff done with energy. We just passed a huge milestone globally!

Now back to work on America.

Something extraordinary just happened

But of course there's a but. Or two.

This means you eventually burn through your pain receptors on worrying about anticipating questions because you never can and so you settle into the zen enlightenment of letting it unfold and going with where it goes

I have only taught mathematics (including mathematics services courses to other depts) and I have adopted teaching inspired by the inquiry method where the class is driven entirely by students answering questions and elaborating on their suggestions

I’m not sure what you mean about storing numbers up to integer accuracy, but I think it is somewhat clear what it means to have a good floating point algorithm for sine

Floating point is way worse than one naively expects

In the same way, one finds that algorithms for the derivative are complicated because using a naive Euler approach can give less accurate answer using a smaller interval e.g. f(x+h) for large x and small h is often no good

By the whole point is finding an algorithm that is uniformly good across how we represent floating point so data storage is intertwined with the algorithm

Obviously the same thing occurs at an elementary level in classical mechanics when we ask if there is an independent way to measure a force or if Newton’s second law is a tautology

This is one of the points in Hasok Chang’s amazing book Inventing Temperature (i.e. without a theory of what temperature *is* how could one know a thermometer were more or less accurate)

The way to administer a welfare state also just cannot be flat payments with sharp falloffs

It is plausible to me that one could teach via simplistic models for helping students inquires towards understanding for themselves about adaption (as a book on evolutionary game theory might do) - I wonder if there are books that take that approach?

Why does everyone sans Grace think that they are trivially smarter than Alan Turing and, more broadly, _any-philosopher with functionalist
inclinations? It seems simply because it fits most conveniently with their other commitments regarding the political economy of LLMs

I’m not sure if it is social media or was ever the case, but the casual trotting out of supposed scientific facts which clearly flatter the prior convictions of the person stating them is really unnerving to me

I think the unhealthy Lysenkian version is to think you uniquely are able to distill the anti-revolutionary wrong think of ‘bourgeois science’

It is interesting to contemplate the social unfolding of ideas and contingencies: symbolic logic re-arising in the British Industrial Revolution along with the beginnings of more modern ideas about democratic citizens

I don’t know about a scientific distinction but I think there are lots of phenomenological distinctions related to the kinds of psychological states the usability improvement tends to bring about
