## Dimensions: Chapter 1

Hipparchus explains how two numbers can describe the position of a point on a sphere.

He then explains stereographic projection: how can one draw a picture of the Earth on a piece of paper?

## Quantum Physics in a Mirror Universe

When you look in a mirror, and see what you think is a perfect reflection. You might be looking at a universe whose laws are fundamentally different.

## How to Predict the Spread of Epidemics

How to predict and model the spread of epidemics.

## Oxford Mathematician explains SIR Travelling Wave disease model for COVID-19 (Coronavirus)

The SIR model is one of the simplest ways to understand the spread of a disease such as COVID-19 (Coronavirus) through a population. Allowing the movement of populations makes the model slightly more realistic and results in ‘Travelling Wave’ solutions.

## Oxford Mathematician explains SIR disease model for COVID-19 (Coronavirus)

The SIR model is one of the simplest disease models we have to explain the spread of a virus through a population.

## How Do Quantum States Manifest In The Classical World?

Quantum mechanics tells us that the atom’s wavefunction can be in a superposition of states – simultaneously decayed or not decayed. So is the cat’s wavefunction also in a superposition of both dead and alive.
