But that's exactly what the ellipsis means. What other interpretation is there? I might as well argue that 1 = 1 only if we agree on the convention that = means "equals".

But the "example from real analysis" section in your link uses exactly the same limiting technique to construct e. That section shows that 0.999... is constructible.

Bu then why does the theorem only hold with more than two candidates?

by soVeryTired 10y ago
Limits use a construction that's pretty similar to an infinitesimal. The epsilon-delta definition of a limit is no joke for students.

They're coming out of the woodwork... Edit: sorry, didn't mean to ad hominem, but I'm going to leave my original comment there all the same. To make my post a bit more constructive, OP, what exactly is your definition of &quo

Yes, but there's some equivocation there. The meaning of 'dictator' isn't quite what you might think it is.

This article describes how economists cut cake, not mathematicians. Mathematicians cut cake into a finite number of non-measurable pieces, rearrange those pieces using only rotation and translation, and end up with two cakes.

Whether or not you approve of hedge funds, they don't exist for the sole purpose of helping companies reduce their tax bill. Most companies of significant size can play tax games without the help of a (sometimes expensive) intermediary

But the axiom of choice is logically independent of the other zermelo frankel axioms. You can assume zermelo franked plus choice, and get the standard framework (ZFC) that let's you build the reals. But you can also assume ZF plus the

By no means am I an expert in this stuff, but don't you need the axiom of choice (or maybe something just a little bit weaker) to construct the reals? I don't think it's fair to say the reals 'most certainly exist'

Can you elaborate on what you think is bad about the IDE-with-extras-plus-console framework? I do research in quantitative finance and I actually find it really useful.

Most people have heard of the Sieve of Erathosthenes: put all positive integers in a list, and delete the number one. Now mark two as prime and delete all multiples of two. Now mark the next remaining number prime and delete all multiples o

Eventually most people have to redeem their investments, though, and they're going to do so in their home currency. A US investor who bought foreign assets in 2014 and sold them today would have been hurt by the 25% USD/EUR rally

The efficient markets hypothesis alone isn't falsifiable. You need a model of information and how it interacts with prices: this gives you a so-called joint hypothesis. The joint hypothesis is merely extremely difficult to falsify. I&#

Most brokers don't charge per share. The good ones charge a fixed fee per trade. So if you trade three times a year you might pay $30.

They're not free, all ETFs have charges. Vanguard's fees tend to be low (e.g. 13 basis points on VXUS), but to say they're free is misleading.

Just to point out to people who may not be aware, this leaves you open to currency risk. The FTSE 100 dropped 3% in GBP terms last week, but maybe 10% in USD terms. This cuts both ways of course: you can make money on favourable currency mo

I broadly agree with what you said about gambling, but if you take that type of reasoning too far it can lead to some dubious conclusions. If I'm free to add fudge factors to a utility function in order to explain an agent's beha
