Space is big. Really big. You just won’t believe how vastly, hugely, mindbogglingly big it is. But DON’T PANIC. Physics is on it. And if you’ve ever wondered which part of physics covers which part of space, fret no more. Here is an awesome map that lays it all out.
Dominic Walliman, “youtuber, science writer and physicist,” has created a wonderful infographic that shows the many branches of physics and how they all come together. He has accompanied it with a brief but informative video that gives a chronological overview of each branch and explains the matters (and energies) it is concerned with.
You may learn, for example, that Condensed Matter Physics describes the quantum physics of many atoms together in solids and liquids and is where technologies like computers and lasers come from. You may also learn that Quantum Field Theory is the closest we’ve gotten to bridging the gap between quantum physics and the Special Theory of Relativity but Quantum Field Theory has not yet found a way to include gravity (!) in it. (That feels like a pretty big gap.)
