From spacetime to chaos theory
Physics is a huge and complex area of knowledge. But besides that, it is one of the most exciting sciences, because it deals with “black holes” , “wormholes” , quantum teleportation and gravitational waves .
But if you haven’t been interested in physics since birth, then it’s quite difficult to figure out how existing concepts fit together — and how they relate to things like inertia or electrical circuits studied in high school.
Moreover, someone is constantly trying to prove that Einstein was wrong , and we heard a lot about Stephen Hawking’s struggle to create a “theory of everything” , so it’s pretty easy to get confused about how this all really fits together (if it does at all).
To finally clarify the situation, YouTube blogger Dominic Valliman created a map showing how many sections of physics are linked together — from the era of Isaac Newton to Einstein’s theory of relativity and quantum physics (with a little philosophy for a better understanding of the subject).
Perhaps even the thought of a “map of all physics” makes you shiver and cause you to sweat - but don't worry in vain when you look at it, it will be much less scary:

You can also purchase a map as a poster here , or download a high resolution image .
If you are still shaking slightly, do not worry - Valliman at the same time made an amazing version with animation, and in eight minutes of pleasant pastime she will take you step by step through the whole history of physics. This video will begin with Newton's apple, and will end with modern scientists, those who are trying to look inside the "black holes" and develop a theory that combines gravity with quantum effects.
The video also tells you that there is a gaping "abyss of ignorance" that physicists will have to fill in to understand exactly how the Universe functions; for example, there are such things as dark matter and dark energy - they “work” exclusively in theories, but they have never been observed in fact, and moreover there is no intelligible explanation of their nature.
As a result of all the above, we can say that the more we learn about the world around us, the more clearly we understand how immediately the space of the unknown is expanding; and this is one of the most favorite features of scientific knowledge.
Accordingly, if someone has already tried to dislocate his brain, wondering about where the Universe is expanding.or what exactly space-time consists of - this guide is for you. After all, if the entire history of world physics can be crammed into a digestible form just eight minutes of screen time, then it suddenly does not seem so terrible.
So watch the video at the end of the article, and then use the information received to impress someone in conversations at the dinner table.
