Right, that's the theory, but what's another concrete Godel sentence that's not a twist on the standard Godel sentence? (As an analogy, in theory there are tons of different ways to construct non-measurable sets, but in pract

The article strikes at the right general idea: that a startup that grows large quickly must have executed an idea that was not widely known (e.g. being exploited well, or in the natural adjacent competency of a current large company). Peter

A p-value of 0.3% is not that low given the multiple hypothesis testing nature of the show. A quick Google result shows that 592 total episodes have been filmed of the show. Under the null hypothesis that there was no cheating in any of th

The article claims that 20 years ago, restaurant margins were 3x higher than today's 3-9% (e.g. 10-25%). I can't find evidence that restaurant margins were ever that massive. In fact the first few Google search results e.g. [1]

The Austrian School seems to have been wrong about the last 15 years' money printing causing inflation. In particular, the general Austrian school would have predicted a lot more inflation by now. The prediction on this has fared so

Agreed that Money Stuff generally technically accurate. The only gripe I have about it is that it has a bias in the direction of "everything is so messed up / comical". This is an irreducible bias as it's the job of th

I thought Russell's History of Western Philosophy was interesting precisely because it gave Russell's personal view on all the philosophers. (This is just like Kenneth Clark's Civilisation.) There are already dozens of dry

According to the article, the gold bars are actually high-purity real gold. Then the difference in price must be the small markup that branded stamped gold bars get. This seems very different from the normal forgery I would expect where th

Awesome products and this makes so much sense given the rise of the cannabis market. I am surprised by the amount of comments here that seem like they are more or less arguing against enforcement of DUI laws that will save lives.

Is this a critique of the article's definition of upper class (which they define as top 10%tile, and you define as non-working class). Or are you saying even given their calculation, their result is wrong?

Also, does the public have the image of Comcast and Verizon CEOs as being specific people who are really rich and dislikable? So that taking them down a notch will make the public happy? And so taking them down a notch is a good political

Correct on your first point. I do not mean I learned the specific version published by Bourbaki, but rather in the modern mathematical style (hence the "a la", as opposed to 19th century hand waving style that nearly all undergra

This is not new. Behavioral Economics has always recognized biases as the result of heuristics -- rules of thumb that are mostly correct, especially with regards to our evolutionary history. However, in specific, predictable contexts,

By Feynman's argument, you can prove that square numbers almost certainly keep on existing. Roughly, it goes as such: 1) the probability of N being a perfect square is proportional to 1/sqrt(N). 2) For any N_0 arbitrarily high, if

A optometrist I went to did my eye exam for $90, and then I decided I wanted the prescription to get my own contacts. First, I asked, and they denied it. Then I literally had to pull out this law and they finally granted it. But they did

I think generally UBTI refers to income that is actually unrelated to the good the nonprofit purports to do. For example, Princeton a nonprofit can totally charge tuition and use it as a base of funding, and not pay taxes on that. They can

Is the economics of this article right? The main problem I have is that the total supply of engineers is huge and Google is benefiting all companies that demand engineers, not just themselves, which is a massive dilution. A Google search

Non-linear combination of PDAF information, along with the contents of the images themselves is an interesting demonstration of the power of neural networks. The general concept of non-linear combination is likely how our brains work too.
