Not that we’re overly consumed with numerical coincidences, but it’s perhaps nice to note that ten years ago today we made a little fuss of launching a new blog site with our first post, a post marking Felix Klein’s 163rd birthday, and a video about the Klein Bottle featuring Matt Parker and Katie Steckles.

### Rubik’s Cube is 40 years old

Invented in 1974, patented in 1975 and released for sale in Hungary in 1977, Rubik’s Cube could certainly be considered to have reached its 40th birthday this year. To celebrate, inventor Ernő Rubik has helped put together a special exhibition at Liberty Science Centre, New Jersey, celebrating the history of the hexahedral enigma. The exhibition, called ‘Beyond Rubik’s Cube’, opens on 26th April for several months.

### IMA seeks mathematical images for anniversary book

You may have heard rumours that the Institute of Mathematics and its Applications is producing a book, published by Oxford University Press, in celebration of its fiftieth anniversary next year. The book will contain accessible and thought-provoking articles on a wide variety of topics through the spectrum of mathematics and its applications.

They’ve now announced that they’re additionally in search of images to illustrate the book, and are seeking submissions. Here’s an extract from their request for submissions.

Illustrations, photographs, computer simulations or even clever doodles — anything that’s colourful and inspirational. […] The idea is that these images should be able to stand alone, like pictures in an art gallery, with minimal explanation. They should ideally be approximately square or portrait style and sufficiently striking to be readable when reproduced at a size of approximately 10cm^2. You need to hold the copyright for the image. […] We also plan to reuse the best images (fully credited to you) in publicity for the IMA, especially its 50th Anniversary.

We’re assuming that here “10cm^2” means 10cm by 10cm, and not having an area of 10cm^{2}, meaning $\sqrt{10}$cm by $\sqrt{10}$cm. Submissions are to be emailed, in a low resolution format initially, to ima50@maths.cam.ac.uk by or before 12th May 2013, along with any appropriate explanation or attribution text, using the word IMAGE in the header.

The IMA is also holding a competition, open to all IMA members, for articles to go in the book. Details of their anniversary celebrations, and the competition, can be found on the IMA website.
