James travels extensively giving public talks all over the UK and the world. These talks are for a variety of ages and abilities, including talks for schools, colleges, universities, festivals or other events.


These talks are suitable for UK and non-UK schools, as well as maths clubs, maths societies, colleges, universities and other events. The fee for an online talk is £325. For live talks, ask for my day rate.


Below is information on some of the talks you can book. If you are an organiser of such an event and wish to book, please read the information below and send a message via the contact page.

Bits and Pieces: Secrets of a Digital World

Hedy Lamar blueHeard about Enigma? Then hear about the other German code machine, Lorenz – a machine used for the most important of messages, including those from Adolf Hitler himself.

Or hear the story of Hedy Lamarr, the Golden Age Hollywood film star and secret inventor who patented a way to transmit messages without being blocked that we still use in WiFi today.

See how messages and photos are transmitted on the internet, and the secret messages that tell a film studio when you are sharing movies illegally.

See how are messages transmitted without mistakes, even from space. And we’ll prove that you can drill a hole in a CD and it will still play – live!

This is a 60 minute talk that takes a look at the hidden maths behind the digital world, from WWII to WiFi.

The Enigma Project: The Enigma Project talk and workshop for schools is currently taking a break.

Alan Turing and the Enigma Machine: 

Alan TuringAlan Turing was one of our great 20th century mathematicians, and a pioneer of computer science. However, he may best be remembered as one of the leading code breakers of Bletchley Park during World War II. It was Turing’s brilliant insights and mathematical mind that helped to break Enigma, the apparently unbreakable code used by the German military. We present a history of both Alan Turing and the Enigma, leading up to this fascinating battle of man against machine – including a full demonstration of an original WWII Enigma Machine!

This talk is suitable for adult audiences and universities.

Here is a clip of me giving this talk at The Perimeter Institute.

Numbers: Masterclass

goldstarIn the early days of mathematics, some numbers and some shapes, with certain properties, were given special meanings. Some numbers represented perfection; some numbers represented love; and to the ancient Greeks, some shapes represented the four elements of Earth, Water, Air and Fire. We will learn and prove many amazing facts about these special numbers, and discover that a history of these mystical numbers is a history of number theory itself.

This is a 120-150 minute masterclass, suitable for KS3, summer schools and Gifted and Talented workshops. This masterclass originated as an RI Maths Masterclass. We ask for no more than 60 students in a masterclass.

The masterclass can also be run as a one hour interactive presentation.

Star Trek: The Math of Khan: 

The original Star Trek featured many futuristic ideas such as warp drives, transporters, and travel to strange new worlds. All of which have been discussed in great detail, by experts and nerds alike. But what about the maths of Star Trek? After all, there’s no such thing as Maths Fiction…

In fact, Star Trek featured many interesting mathematical ideas including; the mathematics of alien biology; a paradox that upset 20th century mathematicians as well as 23rd century androids; and the most important question of all – when on a dangerous away mission, does the colour of your shirt really affect your chances of survival?

A quirky talk I’ve been developing since the reboot of the Star Trek movies (or if you look at it another way, one I’ve been developing all my life). One for science fiction and film fans who want to discover the hidden maths in Star Trek.

I have done this as a one hour talk, or as a 20 minute film introduction. Similarly, other film introductions I have done include Enigma (obviously), Good Will Hunting, The Man Who Knew Infinity (Ramanujan biopic), Jurassic Park, Donald Duck in Mathmagicland and Alice in Wonderland.
