The Warwick Mathematics Society will be selling revision guides for the following first year modules on Thursday between 12:30pm and 1:30pm in the Street:

MA106 Linear Algebra
MA131B Analysis II
MA133 Differential Equations
MA134 Geometry and Motion
ST111/2 Probability A & B

They're free for members of the society and £1 each for non-members. If you can't make it between 12:30 and 1:30, we'll be in the undergraduate workroom until about 4pm for Revision Cafe.

The product of a burly scandanavian with a dream of classifying dynamics, lie groups are one of mathematics' great success stories- completely classified and packaged neatly, these elegant structures now find use in a myriad of research areas; from theoretical physics (lying at the heart of Lisi's G.U.T., as well as tacitly in much and most of quantum mechanics) to the classification of differentiable structures on 4-manifolds (famously used by Donaldson to prove that there are infinitely many inequivalent differentiable structures on , despite there being just one topology) to t

Few theorems in the history of mathematics have acquired the almost legendary status that quadratic reciprocity holds in number theory. First conjectured by Euler, it provides a striking relationship between the primes in terms of the solvability of certain quadratic congruences and has become a cornerstone of elementary number theory. The great Carl Friedrich Gauss was the first one to provide a valid proof and liked it so much that he called it his "aureum theorema" (golden theorem) and provided no less than 8 different proofs during his lifetime.
