Do you think that people understand classical physics?

I've seen some similar projects, but IMO this seems to better capture some of the fine-grained detail

problem set? i'm sorry but we do 21st century mathematics in this classroom. here's your problem category

I don’t know! Just thought your previous reply was a little hyperbolic haha

You don’t care about general Pauli channels, at least?

it’s okay james webb eventually finished

I think you basically always need both: the ability to churn through arithmetic, and the freedom to explore.

to go in in math, they’ll still need proficiency in applying algorithms, because you want to be able to quickly evaluate sub-problems when you’re working on things at a higher level.

and at the same time there are a lot of students that don’t care and will never go into math. They might still need proficiency in applying algorithms, because they’ll encounter arithmetic problems in their lives. Even for students that want

I feel like this comment is so complicated. In general, there’s always some deeper ideas lurking just beneath the surface of an algorithm, which are available for anyone who’s curious. I agree that people should be encouraged to try to understand at a deeper level through exploration,

This year's Quantum Computing Theory in Practice Conference (QCTiP) is scheduled for 04/20/2026-04/25/2026 in Oxford, UK 🇬🇧: qctipconf.github.io

Talk submission deadline is just round the corner: 01/11/2026. Looking forward to many exciting contributions and a great time in Hogwarts🪄, aehm Oxford🎓.

Classical solution of the FeMo-cofactor model to chemical accuracy and its implications The main source of reduced nitrogen for living things comes from nitrogenase, which converts N2 to NH3 at the FeMo-cofactor (FeMo-co). Because of its role in supporting life, the uncertainty surroundi...

The promise of solving the electronic structure of FeMo-co has long been central to the narrative that quantum computers will one day solve world hunger. Now we can finally put the "solving world hunger" part to test since Garnet Chan just solved FeMo-co *classically*!

i think quantum measurements are special because it is claimed that they are general enough to describe any way of learning about the world.

my primary demand on a theory of what happens between measurements is for it to be falsifiable. in the analogies you gave, the effects are at least indirectly detectable.

no problem! i could have used different phrasing

just as photons are corpuscules of light, can’t measurements be corpuscules of reality?

maybe i’ve been indoctrinated by pastor Fuchs but my understanding these days is that a measurement is something that an observer uses to see something that is real. I think it’s hard for me to understand what’s there when we don’t measure.

i agree! i wasn’t trying to be rhetorical, i was seriously asking. i just think that this question is really thorny so one should be specific when one asks for a notion of reality

i guess i don’t really know what that means, like if you can’t measure it then in what sense is any such thing really happening? if you can measure it, then that’s a post-quantum theory that we should verify!

do people want an observer-independent notion of reality?

i mean it seems like we have a great theory for predicting the likelihoods of measurement outcomes, not sure what notion of reality people want?

this is just so cool
