TWDK Chemistry doodle by Giles Meakin

The science of ‘stuff’, Chemistry seeks to understand what things are made of, and how these constituents behave. This involves studying the interactions between atoms and the larger structures they form, predicting further interactions, and deriving practical applications of this knowledge.

Due to the highly versatile nature of carbon and the way it interacts with the other elements, chemistry is traditionally divided into three main subdisciplines. The first is organic chemistry: the study of molecules built around a framework of carbon, hydrogen and oxygen atoms. The second subdiscipline is inorganic chemistry, which is the study of all of the remaining chemicals and their interactions. Finally physical chemists crunch numbers to analyse the inherent properties of chemical reactions and apply the laws of physics to chemical phenomena. These three subdisciplines overlap, combine and are applied to many different fields to produce a range of branches impacting on practically every aspect of the world around us.

Extraterrestrial life
The search for alien life catches many people's imagination and has always been a very public branch of science. So with all this investigation, why has our search revealed nothing? Are we truly alone in the Universe?

Vision
Vision is arguably a human's primary sense- we use it to spot danger and navigate our environment. Despite this, there is still plenty we don't know about how this sense works.

Senses
Our senses allow us to explore and interact with the world around us. Even the simplest living organisms have some way to sense their environment - and some animals can sense in ways we can't even imagine!

Vaccines
There are many open questions surrounding vaccines – but perhaps not the first questions that come to mind. Vaccines do not cause autism, but there are many things we don’t know about them, such as why some wear off.

Microbiome
The ecosystem in your gut - how the microbiome might affect what we eat, what illnesses we get and whether we gain weight easily. How to change your microbiome and why it's such a fuzzy business.
