Why do we live in three dimensions - or do we?
We are aware of 3D space and the fourth dimension of time. But why is it like this? Why would one or two not have been enough? Why not more? Experiments at CERN will seriously be looking for evidence ...

The Forces of Nature
Four fundamental forces rule the universe: gravity, the electromagnetic force and then two that act in and around the atomic nucleus, known as strong and weak. The latter pair act over distances smaller than atoms and so are less ...

Mathematics in Music and Writing
In the first half of this year we look at mathematics and music. Music, with its rhythms and structures, is almost by definition mathematical in flavour. We will explore these ideas in more detail in three lectures. ...

Mathematical Journeys into Fictional Worlds
Literary satire has long used mathematical concepts to reinforce its points. Gulliver’s Travels (1724) played with ideas of dimension, size, and shape, and a century later, Edwin Abbot’s novel Flatland (1884) explored the mathematics of higher dimensions, ...

Does Faith Make Sense of Things?
One of the most common themes underlying both the natural sciences and Christian theology is that the world is ordered or structured, and that this order can be discerned by an inquiring mind and represented theoretically. Dorothy L. Sayers (1893...

Where do Mathematical Symbols Come From?
Where do we get our mathematical symbols from? Why is the set of integers called ℤ ? When was the equals sign first used? How about zero? Good notation tends to catch on quickly, whereas bad notation can obscure beautiful theory.&...

Mathematical Structure in Fiction
Mathematical concepts have often been used to create new structural forms in fiction, as in the works of Raymond Queneau and Jorge Luis Borges. The members of Queneau’s Oulipo group (including Georges Perec and Italo Calvino) ...

The Mathematics of Bell Ringing
This lecture will look at change ringing, which is ringing a series of tuned bells (as you might find in the bell tower of a church) in a particular sequence, and this has exciting mathematical properties. We will ...

The Sound of Mathematics
It has been known since antiquity that there are simple “harmonic” relationships between notes that sound appealing together. This lecture introduces the mathematics of pitch, scales, and just temperament. The pitch of a sound is not ...

The Mathematics of Musical Composition
Pattern and structure are essential to music, from the permutations in a Bach fugue, to the structure of a round. This lecture will explore the mathematics of musical symmetries, such as the “translational symmetry” of the ...
