Exactly. Every instance of the belief that elements of some particular number systems are "real" is a mapping of the human abstraction representing that number system to another human abstraction of some other system of objects th

Appreciate the work you do to keep this site civil. Is downweighing through moderator action a binary feature or is the pressure adjustable depending on the moderator's discretion?

The majority of advice I've received was founded in experiences 10+ years in the past, yes, and did not account for the substantial societal changes that have occurred since. My issue is not that the giver hasn't noticed changes i

I disagree strongly with the article's central thesis, but it is still worth critically examining the source and utility of advice. Even honest and sincerely given advice is often more a form of nostalgia on the part of the giver than

What's the deal with that? Never seen a thread drop off so quickly before.

There are many places where that's a perfectly rational decision. COVID was never going to be completely managed by states less than willing to take draconian measures, the purpose soft-lockdowns was instead to lighten the load on our

Yes. The simple models are simple, the fast and large and useful models are simple. We have a lot of in vitro observations which can contribute to smaller, slower and more accurate models as your linked article mentions, observations which

Good talk. I agree with you (and the articles you linked which I read, BTW thank you for those there's a lot more reading for me to do) in explicit claims that the vast majority of real numbers cannot be rigorously constructed[0], and

I believe they’ve attempted to measure synapse weights from real worms for training the net, the firings themselves are just basic electrochemistry.

I do understand that argument, I just remain unmoved by it. Watch this, I'm about to show you a complete finite representation of an irrational transcendental number: π. That took literally three lines to represent and then an addition

I believe we've been able to model the processes behind neural firings for quite some time now, the issue is more mapping between that micro-scale understanding of how each individual piece in a 10^10 piece puzzle with 10^15 edges affe

> on the rationals tie with reality I feel like this ties back into the distinction between theoretical and applied math. The basis in reality for the integers is counting discrete objects with fingers, for the rationals it's (likel

Right, this is essentially why theoretical and applied mathematics are separate branches. Applied techniques like you described make theory incredibly cumbersome (and, importantly, not better). My argument here is not that applied mathema

Yes, you can generally find ways to manage life with limited precision. Doing so is useful enough that it’s an entire field (applied mathematics). For many cases though it is a better choice to stick with these particular carefully design

You’d want to generalize that to a beam whose length is a significant portion of the width of the universe (at which point you should also consider relativistic effects, so there’s more math you’ll need to define over the rationals), but ev

That’s not isomorphic to the discussion at hand though, which refers to modeling systems. Being able to physically construct an object within epsilon does not imply that you won’t run into precision issues when modeling said object at t

Can you? Most likely. Should you? You’ll need to reprove more than a handful of theorems, and for what? What advantage does using rationals instead of reals get you? You might enjoy taking courses in real & complex analysis, the general
