Science Cafe: Cryptography linked to Sudoku

October 1, 2013

The first Science Cafe of the new series, presented by our very own Dr Sian Jones of Technocamps, will be on 1st October at 7.30pm and as usual will take place in the Cafe Bar at The Gate Arts Centre, Keppoch Street, Roath and is free to attend; no booking required. We hope to see you there!

Sudoku is a popular puzzle found in newspapers and puzzle books. The aim of the puzzle is to replace the missing numbers in the grid so that each number appears in every row, column and mini-grid. Sudoku puzzles are interesting to mathematicians because of their structure, and it is believed that there might be many applications of Sudoku type puzzles. One such application is in the field of Cryptography. This talk will show you a method of how we can use Sudoku puzzles to encrypt messages so that they can be sent secretly.

To ensure that Cardiff Science Cafe can continue in 2014 we are looking for new volunteers to join the coordinating team. Science Café is a long-standing engagement with science project where, for the price of a cup of coffee or a glass of wine, anyone can come to explore and debate the latest ideas in science and technology. There are a number of roles available for those with a passion for science and science communication – please email helen.reardon@southwales.ac.uk for details.
