Open Season: Prime Numbers (part 2)
In this short series of articles, I’m writing about mathematical questions we don’t know the answer to – which haven’t yet been proven or disproven. This is the third article in the series, and across two parts will discuss various open conjectures relating to prime numbers. This follows on from Open Season: Prime numbers (part 1).
So, we have a pretty good handle on how prime numbers are defined, how many of them there are, and how to check whether a number is prime. But what don’t we know? It turns out, quite a lot.
Your suggestions of iPad apps for university mathematics teaching
I asked in the previous post for suggestions of iPad apps that I could use to help with my job as a university lecturer in mathematics. I asked specifically about annotating PDF files I had made using LaTeX and recording such activity. More generally, I asked what other apps might be useful to my job and for other uses I should be thinking about. People made suggestions via comments on that post, Twitter and Google+. Thanks to all who responded. Here is a summary of the recommendations I received.

I don’t think it’s too much of an overstatement to say that prime numbers are the building blocks of numbers. They’re the atoms of maths. They are the beginning of all number theory. I’ll stop there, before I turn into Marcus Du Sautoy, but I do think they’re pretty cool numbers. They crop up in a lot of places in maths, they’re used for all kinds of cool spy-type things including RSA encryption, and even cicadas have got in on the act (depending on who you believe).

iPad apps for university mathematics teaching: your suggestions please
New game, everyone! Work have bought me an iPad. I have so far discovered this is basically a touch screen interface through which I can write email, read Twitter and play pinball, but I’ve heard a rumour that it can do even more than that. I’d like you to suggest what else I might do with it.
