Anyone alive in the eighteenth century would have known that the longitude problem was the thorniest scientific dilemma of the day. Lacking the ability to measure their longitude, sailors had been literally lost at sea as soon as they lost sight of land. Join Dr Rebekah Higgitt (University of Kent ) who will tell the fascinating longitude story together with tales of scientific endeavour, challenges and rewards, daring and danger, feuds and skull-duggery!

Tigers have stripes, leopards have spots, and some cows have large irregular patches. How do these patterns in animal markings arise? About 60 years ago, Alan Turing showed his colleagues a drawing with irregular black-and-white patches, asking them whether they agreed that it looked like a cow. In 1952 he published ‘the chemical basis of morphogenesis’, suggesting a chemical process to create animal markings, and a mathematical equation describing that process. These ‘Turing equations’ lead to patterns that are remarkably similar to those found on many animals, including complex stripes on fish and intricate patterns on seashells. Recently biologists have started to work out exactly which molecules and genes are involved. The talk will be an informal and highly illustrated discussion of these patterns.

## Prof Reidun Twarock

### Professor of Mathematical Biology at the University of York

**Title:**

Viruses under the Mathematical Microscope: Deciphering the Code of Viral Geometry

**Date:**

__Time__:

12.30-13.00

__Venue__:

Isaac Newton Institute for Mathematical Science

Viruses, such as hepatitis and the common cold, have highly ordered protein containers that encapsulate the viral genomic material. They act as Trojan horses, transporting the genomic material inside a cell to hijack the cellular mechanism and produce new viruses. Insights in how these capsids are organised are key to understanding how viruses work and how they can be defeated. In this talk, Reidun Twarock will explore virus architecture under the mathematical microscope. We will show that symmetry plays a key role for virus structure, and that mathematical tools similar to those used in the study of Penrose tilings provide novel insights that shed new light on viral evolution and on how viruses infect their hosts.

## Dr Robert Hunt

### Deputy Director, Isaac Newton Institute

**Title:**

Maths at Work in the Real World

**Date:**

Saturday 25 March 2006

__Time__:

12.00-13.00

__Venue__:

Isaac Newton Institute for Mathematical Science

20 Clarkson Road

Cambridge

CB3 OEH

Explain how mathematics, which can sometimes seem abstract and irrelevant, is at work in our everyday lives. All around us, from tools which we use on a daily basis (such as mobile phones) through to scientific advances in medicine (such as PET scanners), are examples of how high-powered mathematics is responsible for things that we take for granted in the modern world. And maths turns up in nature in the most unexpected ways!

The talk will take a light-hearted tour around the usefulness of maths in the real world and will try to explain what the point of studying maths is anyway; concluding with a challenge to find any aspect of life, the world or the Universe which is not intimately related to maths. The talk will definitely be aimed at non-experts.

Professor Sir John Kingman will explain how even the most unpredictable things in the world can be studied mathematically. Maths often deals with things that change in a very predictable way, like the planets going round the sun. But much in life is quite unpredictable: the weather, the stock market, football results and so on. Can maths say anything about these? The answer lies in ideas of probability, an old but rapidly developing branch of mathematics. You will not learn to predict the future, but you may be able to move the odds in your favour.
