Fifth Form and Lower Sixth Form pupils enjoyed an educational mathematical and computational walking tour of central London followed by a fascinating lecture looking at the Maths behind optical illusions.
The walking tour guide took the group to many significant locations in the history of mathematics and computing, from discussing the architecture of Sir Christopher Wren's design of St Paul's Cathedral to visualising Bill Phillips' water computer that simulated the British economy. The Lower Sixth Form Further Maths students had been learning how to approximate functions as polynomials in their Maths lessons before the trip and were thrilled to hear how these same techniques were used to compute logarithm tables, the master copies of which were stored at the government buildings at Somerset House.
The evening lecture at Gresham College was delivered by Alain Goriely, prominent professor of mathematical modelling at the University of Oxford. He examined how optical illusions can be modelled with mathematical functions, including in geometric art such as works by Kandinsky and Klee, as well as unintentional illusions in paintings by Munsch and Rubens. The students were able to recognise many mathematical techniques used in the modelling and enjoyed hearing how illusions could be 'corrected' by applying the opposite effect. Themis and Matthew were able to ask questions of Professor Goriely in the Q&A, with many of our other students taking the opportunity to wait behind at the end to pose further questions.
The intention of the trip was to stretch and challenge our students, and they certainly enjoyed the chance to think beyond the curriculum.
