You're simulating a full game of poker. Once a player has been given card 'i', you have to ensure that card 'i' isn't drawn again during the game. You could maintain a set containing all cards that have alrea

There are recruitment agencies which only take individuals with autism on their books, and try to find them roles which suit their particular skills profile. A quick Google should turn up some useful results, but be careful to not be taken

Horses for courses. Whilst I'm skeptical that we're at the stage where mechanical proof-checking is viable, such a technique would be immensely valuable. On the other hand, it is of course true that if the proof itself is mechan

What a ridiculous article. The statement "70% [are] on prescription drugs" is devoid of moral content. If the title had been "70% are on prescription drugs unnecessarily" or indeed "70% misuse prescription drugs&q

Scientists definitely do have a test for the so-called IQ, and it's called the IQ test – but 'Intelligence Quotient' and intelligence are not synonymous. One need only read Mensa magazine to realise that IQ does not constitute intelligence

What I mean is that since Goodstein's theorem is provably true for the naturals, but is not a consequence of the Peano axioms, then the definition of the naturals used to demonstrate Goodstein's must be strictly stronger than the Peano axio

How then are the naturals defined? By the Von Neumann construction? (0, {0}, {0, {0}}, ...)

Agree - especially given that this was funded by the Campaign for Real Beauty, and it wouldn't exactly have supported Dove's ad campaign if the pictures looked the same or the sketch was reversed.

I know, I was being facetious. I just like the thought of the campaign finishing and runn1ng posting each of his sponsors a $0.99 protractor.

I use a similar workflow with SVN to great effect. I have never had a sync issue - whether this is luck or that the repository structure is more robust in this setting than Git's, I don't know. I would strongly recommend against using this

Looks good - I've signed up :) I would say though that I think your articles and lectures could do with a bit more organisation. In both cases, the user would benefit from posts having tags denoting subject content, and from a search facili

Perhaps your experience has been different from mine, maybe because I'm based in the UK - I know that US education tends to be more generalised. Among my friends with or pursuing postgraduate degrees in pure mathematical disciplines, none h

That seems a pretty strong generalisation. A doctorate in Model Theory doesn't give you the authority to talk stats.

I agree with you that the ... notation is ill-defined. It's common in mathematics to use conventions that are a little woolly, but only where everyone understands how to express the idea more correctly. Here's one way of presenting this for

All good fun problems - and some less well-known as well as the old favourites. That said, calling these the "12 most controversial facts in mathematics" is like calling the truth of the moon landings the most controversial fact in astronau

I think the point is that storing even encrypted passwords is not as safe as storing (salted) hashes, because if the database was compromised, the encryption key would likely be compromised as well. It's safer if even the site themselves do

I had to read this three times before I realised you were being sarcastic. My blood pressure does not thank you.

I think this is very dependent on the area of maths. In applied mathematics, obviously simulation is of huge importance; and in very fundamental pure maths the language is close enough to formal logic to make it easier to apply computer-aid

Big fan of this app - definitely something I'll make use of. One idea though: something that as a singer I would find useful is the ability to select a single base note and practice against that but without the base note being played each t

Absolutely. For example, the ingroup bias allows a group of related individuals to benefit at the expense of those with whom they are less likely to share genetic material; and the observation bias allows our brain to focus on information t

It's a shame to see the driving/flying statistic trotted out again. My absolute chance of dying in a car crash as opposed to a plane crash is irrelevant when deciding which to take - as an individual I'm far more likely to die of drowning t

This is really great - love the idea. Just in case you hadn't spotted, I think there's a punctuation bug whereby characters are sometimes omitted, although it doesn't happen all the time. Not a big deal though. Example: Correctly punctuated

In principle, not every number can be directly expressed as the result of a nontrivial Ackermann function or Knuth operator (just as not every number is a square or a cube) - although there is a section in the Knuth page you linked on how t

Presumably it rather depends on what you're storing such large numbers for. If you want to store a single number n (for the sake of argument, let's say a positive integer) for later reference, and have no knowledge in advance of any special
