After ten years of making avant-garde videos, I was inspired to change my direction entirely, and go for a big adventure in the world of mathematics! I'm currently half-way through a maths degree with the Open University, and I'm loving it!

Update 21.3.14: I was near to completing my undergraduate degree, however, I decided to go it alone for a bit, so that I have time to read other maths books, solidify what I've learned, and further explore/revisit branches which particularly interest me. I may even write a paper before I finish it, and do everything the wrong way round!

I also now work in the daytime as a programmer, harvesting data, hunting for discrepancies and errors, and fixing robots, and by night and on the weekends I study maths. It is always a challenge to see how much stuff I can get done in a small amount of time. But the ultimate challenge would be to somehow work on maths problems at the same time as my day job!

comment What is it that determines the degree of a tile, and to what extent does the shape of a tile determine its degree?
I'm referring to any tiling of the plane initially- I suppose, an additional question would be, to what extent does the type of tiling affect my question? Presumably the degree of a tile, and the symmetry group must be interconnected?

comment What precisely is the difference between Euclidean Geometry, and non-Euclidean Geometry?
Thanks for an excellent illustration of how Euclidean and non-Euclidean Geometry differs, and you are very clear!

comment Prime decomposition of an integer: methods of determining the prime factors $ p_1, p_2, …, p_r$ and powers $k_1,k_2, …, k_r$
I haven't yet worked out the prime factors of this number. In fact, it could be divisible by any prime $\leq \sqrt{567788}$... So, actually, I'd be interested in learning methods of determining prime factors of large numbers too.

comment Representing Recursion and Primitive Recursion diagrammatically
Thanks for your excellent description of the difference between how primitive recursive and recursive functions behave. I can now see that the difference lies in the nature of the loops. Depicting this will be an interesting project- I'll have to post it on here, as and when I come up with something! Your book looks really interesting- I shall have to track it down.

comment Primitive recursive functions and characteristic functions. Methods of proof- examples. Illumination.
Thanks so much for your answer. I think I can see the thinking behind this now- well, I get how the algebra works anyway, and mostly get the rest of it... In answer to your questions- I am referring to f in the context of inferring the parity of n, i.e. $\chi_E$ This is what I meant by f and g doing the same thing. The overall topic in the textbook that I'm reading is 'characteristic functions'. Just one more thought- presumably $\chi_E$ would only be valid for the two cases 'n even' and 'n odd'?

comment Primitive recursive functions and characteristic functions. Methods of proof- examples. Illumination.
Ah, I did indeed miss out the 'n's! I see that f and g obviously don't do the same thing, but it is presumably no coincidence that g has been written in the way that it has. I think I'll sleep on that and take another look at it tomorrow(!)

comment Representing Recursion and Primitive Recursion diagrammatically
Thanks for your comment- it might well be the sort of thing I had in mind! Looks really interesting anyway. I have edited the second paragraph in my question, so that it is hopefully a little clearer what I mean. In general, I'm interested in any form of visual representation of recursion, and recursive functions.

Thanks for the excellent advice- I shall see if I can track those down!
