Domain of Science

Domain of Science is made by Dominic Walliman, a physicist with a PhD in quantum device physics. He is also the author of the Professor Astro Cat science books for children.

The channel is best known for its maps of whole subjects. Each one shows how the branches of a field link together, using hand-drawn animation and a clear voiceover. There are maps of maths, physics, chemistry, computer science and engineering, among others. Other videos explain hard topics such as quantum physics in simple steps.

Some highlights include:

A map of engineering that shows the main branches, from civil and mechanical to electrical and chemical, and how they connect.

A map of mathematics, from its foundations to the differences between pure and applied maths.

A map of computer science, covering theory, hardware, software and their applications.

The channel has around 1.67 million subscribers.

Few resources show the whole landscape of a subject so clearly. The Map of Engineering is especially useful for students who know they like engineering but are not sure which branch suits them. The channel helps with choosing A levels and degrees. The maps are also useful revision tools, because they show how topics from different lessons link together. Watching the maps for maths, physics and computer science side by side shows how much these subjects overlap, and why engineers need a bit of each. They make a good starting point for conversations with teachers and parents about future options.
