I'm dissappointed to see you're being downvoted for what looks like a good faith (and common) misconception with a request for more information. Anyway, the best way to learn more about this is to search for resources describing t

It's a complete mess when working on actual engineering tasks, I can't imagine how many hours have been wasted converting/correcting between units used by standards versus projects. There's also abominations like the Ene

Swamp coolers cool based on evaporative cooling: water evaporating into dry air reduces the (dry bulb) temperature of the air. So with high wet bulb temperatures indicating air is already saturated with moisture, the swamp cooler won't

Is there some high-level mathematical way to interpret these normal forms? I am not familiar with relational databases and just googled database normalization to get a kind of crude idea of what you are saying, but all the examples I find d

We donated to six charities and I ended up learning a lot (from a position of significant ignorance) about the charity landscape. I was shocked to find out that $33 per month can fund a full undergrad scholarship for a student. I was partic

Recently I was looking to donate some money to Sri Lankan charities and was talking to various groups, asking them what their most urgent needs were and where I should allocate money. One charity was based in the Mullithivu region[1] which

If you know what you're doing, having access to a universal approximator is lethal. But if you don't, it's true, you can only replicate previous successes in the domain, and that will be the limiting factor.

Interesting, but this seems to contradict(?) the fact that there are 4+ spatial dimensions. This reminds me of passage in a book or movie (can't remember which one) which talked about the idea of human beings in 4D as worms, with the t

One thing is that we can only move forward in time. I have always heard the second law of thermodynamics (entropy always increases) defines the "arrow of time": you cannot go back to a previous ordered state unless you add work, t

Does the base really have anything to do with 5? I can represent 5 in base 10 as 5, or I can represent it in base 2 as 101, but both encode the same information. Using different bases, to me, is just about storing information. How many symb

I prefer to think of natural numbers as a 1D vector. Negative numbers are therefore just a function of the direction of the vector. I don't have a good explanation of what zero is in this context... Would someone else have a way to exp

You're a great writer, if you wrote a book about your experience I would buy it.

I would love to see this incorporated into a HUD in actual cars to augment unsafe driving conditions. For example outlining cars, roads clearly during the night or rainy/snowy weather.

I feel like it would take superhuman restraint to not work it in once during 30 years though. If it were me I'd never shut about it.

This is the best explanation I've read thus far.

Ah! I see, I thought the commentator was saying to solve it mathematically. Manually "simulating" it makes sense.

Using Bayes theorem? But if you know to use Bayes theorem, then you're already formulating the problem correctly, which is the problem all the critics are running into. Edit: Someone mentioned you could manually "simulate" it

I guess Monte Carlo simulations weren't well-known or easily accessible back then? It would have been the perfect way to shut up her critics.

I only recently started learning about vector embeddings, and the thing I can't wrap my head around is why cosine similarity should be so effective when (to my understanding) it should only capture linear similarity. Shouldn't tha

Seconded. This is exactly the same stackexchange post I thought of as well.

I noticed this too, because it seemed to be a common theme for many of the men, and also, pretty relatable. Who doesn't think of themselves as capable of "extraordinary things"? If they could recontextualize failure as advers

Is the area/volume constraint in space related to the one in organisms? The latter I can understand intuitively as a function of scaling metabolic rates for different organism sizes. Specifically, there's some power-law relationsh

The second part of your question is thought-provoking. There are a lot of works of fiction that have inspired me due to broad themes, but there are a lot fewer whose inherent "structure, language, [and] composition" have inspired.

100% agree, having different point representations is a pain. I also don't like it when they're represented as objects (which is almost always the case). It seems so much more powerful, and expressive to me to just keep it as a tu

Interesting, I have a couple of questions: - How do model random variables with high variance like occupancy or equipment use? Are you using sensor/monitoring equipment or just trying to model it as best as you can? - Did you guys use
