If there is higher supply of a good then the price goes down and the amount of the good sold goes up. This is entirely symmetric to higher demand leading to higher prices which results in more supply. People will not buy mud pies unless the

By the same logic, changing demand presupposes an inefficient market. Changing demand in the absence of higher supply will only result in demand not being met.

If you increase the supply of fast food you increase competition which lowers prices so people will consume more. The economy is obviously driven by a balance between supply and demand, with prices being the mediator.

Multiplying a matrix by a matrix is a lot more expensive than a vector by a matrix.

Perhaps the extra experience is not worth 50% more? I'd be wary about calling an entire industry irrational when they're spending their own money.

QM did not go into blind math mode. The way physicists usually do QM is by glossing over a lot of the subtleties of Hilbert spaces and act as if the results from finite dimensional linear algebra work. Concepts physicists have been using fo

Species don't change so that the conditions become ideal for that species, species change so that the species is (close to) ideal for dealing with that environment. This is a very important distinction. Certain plants may grow in the d

You can still reason by analogy with something you can visualise. You can't visualise 3+1 = 4 spacetime dimensions, but you can pretend that space has 2 dimensions so that you can visualise it as 2+1 dimensions. Blind algebra rarely wo

Right, those are two different names for the L_1 distance, but why does that show that they're not the same? For binary vectors v,w we have abs(v[i] - w[i]) = v[i] xor w[i], and the L_1 distance is the sum of the former whereas the Ham

Isn't the hamming distance simply L_1?

Wouldn't that give infinity or zero depending on whether the range of your values is larger or smaller than 2?

The ^2 gives the normal distribution, which is special for many reasons. With ^1 you get the Laplace distribution. This is widely used when the data is sparse (has many elements exactly 0). This is less sensitive to ourliers and in image re

The old rules about sexual conduct were very clear: making a sexual advance is wrong unless you are married to that person. After the sexual revolution the rules have become very murky. Take the Hollywood scandals. Why exactly is it wrong t

How do you know that voter fraud rarely if ever happens if you don't ask for an ID? Why does requiring an ID disenfranchise people? If people are prevented from getting an ID then surely the issue is that people are prevented from gett

Why is the focus almost entirely on not requiring identification for voting then, and not on making it easier to get an ID? It seems to me that, unless the point is to allow people to vote illegally, getting people an ID is a far more impor

Why can't you get the ID some time before the vote?
468.
by jules 9y ago
I don't understand the problem. If you do not have an ID you do not get to vote. The reason why you do not have an ID is irrelevant; without an ID they cannot verify that you are casting your own vote. Without this requirement it would

No, that is not an excuse. They will not let you vote if you do not have an ID. Why should it be an excuse anywhere? I just looked it up; getting an ID is cheaper in the US than in the Netherlands. If it is somehow extremely difficult to ob

That would be a good point if an ID was not required for many other activities. I don't understand why people think it's voter suppression that you need an ID to vote, but not, say, marriage suppression that you need an ID to marr

Wouldn't this suppress republicans more than democrats?

The question is not whether you have to carry an ID on you at all times, but whether you have to show your ID to vote. Having an ID does not really change anything with respect to anonymity, unless you have to carry it. Something that reall

In the Netherlands we require ID to vote and having an ID is not free but it is compulsory. In most cities there is only 1 place where you can get an ID. You also automatically get a hard to forge letter in the mail that you have to bring w

Not always; the unknowable information in quantum mechanics is simply not there. It's not that there is no way to get at the information in practice, it's not even that there is no way to get at the information in theory. It'

Depends on your point of view. If you something is not knowable even in principle then maybe the question was wrong, like "how many angels can dance on the head of a pin?". A better answer is perhaps that there are things that we

If we look back on the development of relativity and quantum mechanics with the benefit of hindsight we see that there were already many clues in classical physics. Perhaps our current experimental evidence and current theories have enough

Learning statistics is like learning anything else. Kids who want to make a video game are often dismayed when they realise how much they'd have to learn. If they ask how you put a walking character controlled by the mouse and keyboard

You can also think about Bayes' theorem as follows. Suppose we have a logical robot trying to learn about the world. The robot has a collection of hypotheses in its brain. Every time it observes a new fact, it deletes all hypotheses th
