Maths & Science

peterjamesthomas.com is a business-focussed site, however regular readers will have noticed the frequent appearance of topics in Mathematics and Science; with observations and learnings from these fields frequently being applied to business. Perhaps an archetypical example of this is my 2014 article, Data Visualisation – A Scientific Treatment.

By way of contrast, this new section houses articles that are avowedly Mathematical or Scientific in nature with no other context applied. These will be less numerous than my business pieces and may well appeal to a very different audience. I do however hope that there is some cross-over between these sections.

1. Glimpses of Symmetry (work-in-progress)

Glimpses of Symmetry

This is an on-line book, which uses the Standard Model of Particle Physics as a motivation for providing an introduction to an important and beautiful area of Pure Mathematics, Group Theory; a subject I studied in Graduate school.

At present the book is about 75% complete and some chapters are either drafts or placeholders.

The Irrational Ratio

The Irrational Ratio

The number π is surrounded by a fog of misunderstanding and even mysticism. This article seeks to address some common misconceptions about π, to show that in many ways it is just like any other number, but also to demonstrate some of its less common properties.
