# The Number Mysteries (Online)

## Overview

Based on Marcus du Sautoy's book The Number Mysteries, this course explores the question, how natural is mathematics? Through numerous online activities and 'at home' experiments, you will interact with mathematics as you never have done before.

Today's world is full of technological advances which are only possible due to the huge leaps that science has made over the last few decades: the structure of DNA, the microchip, splitting the atom. Yet, as diverse as these major discoveries may seem, they are all understood through the language of mathematics.

Mathematics has come a long way from its humble origins of notches on a stick and through this ten week course we will take you all the way from the beginning of the number system to the very edges of the universe.

Packed full of diverse activities to suit a wide range of learning styles, The Number Mysteries maths course is for anyone who wants to go on a mathematical odyssey which may change the way they think forever.

## Certification

Credit Application Transfer Scheme (CATS) points

To earn credit (CATS points) for your course you will need to register and pay an additional £30 fee for each course you enrol on. You can do this by ticking the relevant box at the bottom of the enrolment form or when enrolling online. If you do not register when you enrol, you have up until the course start date to register and pay the £30 fee.

Coursework is an integral part of all online courses and everyone enrolled will be expected to do coursework, but only those who have registered for credit will be awarded CATS points for completing work at the required standard. If you are enrolled on the Certificate of Higher Education, you need to indicate this on the enrolment form but there is no additional registration fee.

Digital credentials

All students who pass their final assignment, whether registered for credit or not, will be eligible for a digital Certificate of Completion. Upon successful completion, you will receive a link to download a University of Oxford digital certificate. Information on how to access this digital certificate will be emailed to you after the end of the course. The certificate will show your name, the course title and the dates of the course you attended. You will be able to download your certificate or share it on social media if you choose to do so.

Please note that assignments are not graded but are marked either pass or fail.

## Tutor

### Dr Thomas Woolley

Dr Thomas Woolley, applied mathematics lecturer at Cardiff University, studied mathematics at University of Oxford between 2004-2017. Through his education he ended up specialising in mathematical biology, where his doctorate focused on understanding the pattern formation behind fish spots and zebra stripes. Along side this research he now investigates mathematical models of stem cell movement. The hope is that by understanding how stem cells move we can influence them and, thus, speed up the healing process.

When not doing mathematics he is a keen participant in mathematical outreach workshops and has given a variety of popular maths lectures nationally and internationally. He has previously worked for the BBC, illustrated Marcus du Sautoy’s book and worked on the popular maths show “Dara Ó Briain: School of Hard Sums”.  Most recently he was the Fellow of Modern Mathematics at the London Science Museum and helped redesign their mathematics gallery.

## Course aims

This course aims to

• give students a deeper knowledge and understanding of the concepts of number, shape, the role of logic and probability in game play, the role of mathematics in codes and the power of mathematical equations to predict the future;
• provide students with activities that allow the students to interact with mathematics on a level which they may not considered before;
• show how mathematics permeates many aspects of our daily lives;
• aid the intuition of the participants when dealing with probability;
• show the beauty behind the equations that mathematicians use.

This course will enable students to:

• have confidence in situations where numerical processes are necessary.
• question the statistical data that the media presents as fact.
• organise problems logically, stating their assumptions and understanding their conclusions.

## Learning outcomes

By the end of this course students will be expected to understand:

• mathematics is the language of the universe;
• mathematics is more than just numbers;
• intuition may not always be correct;
• the power of proof;
• mathematics allows us to explore theoretical systems without the need of physical experiment.

By the end of this course students will be expected to have gained the following skills:

• Discuss mathematical ideas competently.
• Suggest possible applicable branches of mathematics to new problems.
• Clarify and evaluate assumptions based on their applicability.
• Aid their intuition through mathematical insights.
• Transform known solutions to new problems.

## Assessment methods

You will be set two pieces of work for the course. The first of 500 words is due halfway through your course. This does not count towards your final outcome but preparing for it, and the feedback you are given, will help you prepare for your assessed piece of work of 1,500 words due at the end of the course. The assessed work is marked pass or fail.
