Bestselling author Professor Ian Stewart is your guide through Incredible Numbers. Numbers define the patterns of sunflowers; they bring pleasure through music; and they help us answer existential questions like; ‘How many ways are there to lace my shoes?’ Interactive examples – from simple equations to a working Enigma machine – put the beautiful concepts behind mathematics at your fingertips.

“A measure of Ian Stewart’s success is that he’s able to give a clear path through some very hairy mathematics.” – Times Higher Education Supplement

There’s so much more than a few screenshots can show:

– 23 articles crafted by Prof. Ian Stewart, embedded with 71 groundbreaking interactive demonstrations.

– 23 bespoke interactive sections that let you immerse yourself in the beautiful patterns and concepts behind each topic.

– 15 of Ian Stewart’s famous mathematical puzzles.

Topics include:

• Infinity – Explore infinity and understand what it really means to say something is infinite.

• Pi – Unwrap the mysteries of pi to see why this strange number is so important and why it’s not just about circles.

• Music – Music and math share the beauty of finding patterns in complexity. Detailed interactives show you how they relate in real, meaningful and fun ways.

• Codes – See how the power of numbers can unlock complexity in codes.

• Nature – See how numbers work in nature by looking at the Fibonacci sequence and how it appears in the real world in beautiful and surprising ways.

• Primes – Discover the mysterious patterns in prime numbers, and why they are so important.

• Polygons – Get to grips with shapes and polygons. Classical geometry is just another way to think about numbers!

• Factorials – How many ways can you lace your shoes? Did you know that if you have 4 eyelets, there are 24 possible lacing styles? With 12 eyelets there are 479,001,600 possibilities. See why this is so in Factorials!

Incredible Numbers aspires to convince you that maths is beautiful. Mathematicians know this already. The great solutions and proofs shine to them, but their underlying beauty has been hidden behind abstract algebra and complex equations. Until now.
