Domain of Science is produced by physicist Dominic Walliman who is on a quest to make science as easy to understand as possible. His most popular videos lay out the fields of science as maps which show how the sub-disciplines relate to each other, but he also delves deep into specific subjects with a distinct skew towards quantum physics (probably because he’s got a PhD in it). Dominic is also the author of the popular Professor Astro Cat series of science books for kids.
