# What is Quantum Field Theory?

A brief, purely discursive, post explaining the motivations for and success of Quantum Field Theory.

Today we will present the basics of Group Theory. Group Theory is essential to theoretical physics as it examines the symmetries of nature to uncover fundamental connections and patterns within the universe.

Revisiting the theme of time we explain the geometry of spacetime and explore the special quantity known as ‘proper time’. A qualitative post which includes the use of simple graphs.

A post which explains the five main laws which govern the quantum world. The post is purely qualitative and requires no use of mathematics.

A brief introduction to the biggest contender for a unified theory – a 2000 word introduction to string theory requiring no mathematics.

A brief introduction to the weird world of quantum computing. Learn how a small number of quibits can quickly transform into something wonderfully complex.

A brief introduction to the increasingly important world of neutrino physics. The little stuff is shy, mysterious but fundamentally the material from which reality is constructed. Shall we?

Whether or not we have a free will is an age old question in philosophy. Today we discuss whether we are truly in control of our decisions and whether our future is a genuine uncertainty.

In 1915 Gravitational Waves were predicted by Einstein as a product of his theory of general relativity and in 2015, on the theory’s 100th anniversary, their existence was verified. Find out what all the fuss about and how the long awaited detection came about.

How deep does the rabbit hole go? Explore the basic theoretical underpinnings for information theory and how this leads to some challenging theories of reality.
