Closer to understanding pi

Researchers in a Swiss university have just calculated π to 62.8 trillion decimal places, setting a new record. We don’t really need this many digits – indeed, it’s been estimated that around 40 digits are sufficient for any calculations on an astronomical scale – however, the act of knowing this irrational (and transcendental) number with ever greater certainty is an inspiring challenge that has occupied human thought since ancient Egyptian times and possibly earlier, as evidenced in the Rhind papyrus of around 1650 BCE. Also, the technology used in generating this value can be utilised in other more practical areas such as fluid dynamics.

The constant π is inextricably linked with circular measure, which in turn makes it essential for calculations involving periodic processes in both the natural and constructed worlds; it is also invaluable in modelling random processes associated with probability.

Simply Maths

I’m working on a new exciting maths book for Dorling Kindersley, called Simply Maths.

This book is highly visual and offers a digested version of the big ideas behind each of the major topics, so that you can gain a broad understanding without having to cross the mathematical pain threshold! 

For students and the interested layperson alike, and most importantly for those who have a lifelong nervousness of the subject, Simply Maths publishes in February 2022 and can be found on the Dorling Kindersley website here:

The Visual Encyclopedia

This vast reference book, published by DK, is out now and contains a maths section written by me – along with lots of wonderful pages on diverse subjects such as history, astronomy and transport. You’ll never need the Internet again!

The Visual Encyclopedia

Look out for this fully comprehensive reference book published by Dorling Kindersley, and covering diverse aspects of the arts, sciences, mathematics, history, religion and much more. This is a real family resource that will be of interest to parents and children, as well as teachers and adults, anyone really with an inquiring mind. All content is delivered with Dorling Kindersley’s engaging visual approach, to ensure that the topics really come to life.
I do have rather a vested interest in this book as I have written the mathematics section!
The Visual Encyclopedia is due to publish on 1st October 2020.

The Maths Book – coming soon!

The Maths Book is available from 5th September 2019, published by Dorling Kindersley. The main premise is that it’s about big ideas, simply explained – so if you ever wanted to know a bit more about maths than the half-remembered and three-quarters forgotten stuff on fractions that you might have learned at school, this is the book to get hold of.

I’ve been working on an exciting new book for Dorling Kindersley, entitled The Maths Book, in the Big Ideas series. This has involved working with the lovely people at Toucan Books, authoring some of the articles and acting as publishing consultant.

The book explores the major concepts in mathematics throughout history, and should hopefully be a fascinating read. It publishes in September 2019.

March 14th – it’s Pi Day!

Take a  moment today to reflect on 14th March, or 3/14 as it’s often expressed. Today is Pi Day, named after the fascinating proportion of a circle – the ratio of its circumference to its diameter. This number is both irrational and transcendental – nobody really knows what it is in total accuracy. However you can learn the first few decimal places for yourself – just count the letters:
