The field of computer science summarised. Learn more at this video's sponsor https://brilliant.org/dos

Computer science is the subject that studies what computers can do and investigates the best ways you can solve the problems of the world with them. It is a huge field overlapping pure mathematics, engineering and many other scientific disciplines. In this video I summarise as much of the subject as I can and show how the areas are related to each other.

A couple of notes on this video:
1. Some people have commented that I should have included computer security alongside hacking, and I completely agree, that was an oversight on my part. Apologies to all the computer security professionals, and thanks for all the hard work!
2. I also failed to mention interpreters alongside compilers in the complier section. Again, I’m kicking myself because of course this is an important concept for people to hear about. Also the layers of languages being compiled to other languages is overly convoluted, in practice it is more simple than this. I guess I should have picked one simple example.
3. NP-complete problems are possible to solve, they just become very difficult to solve very quickly as they get bigger. When I said NP-complete and then "impossible to solve", I meant that the large NP-complete problems that industry is interested in solving were thought to be practically impossible to solve.

How Big is The Universe?

We begin at the familiar blue and green orb we call home and zoom out to explore the vastness of space. From the Moon, our closest cosmic neighbor, to the edges of the observable universe, prepare to be astonished by the sheer scale of everything that exists.

Travel with us as we venture past the Moon, understanding its distance in terms we can grasp. Witness the Sun, not just as a source of light, but as a milestone in the vastness of our solar system. We don't stop there; Mars, Neptune, and the outer reaches of our solar neighborhood await.

Discover the awe-inspiring distances to the Voyager 1 probe, the enigmatic Oort Cloud, and the neighboring star system of Alpha Centauri. As we sail through the Milky Way, understand our position in the grand scheme of things, where our entire history is just a whisper in the cosmic wind.

Our voyage takes us further, to the Local Group, Virgo Supercluster, and the staggering Laniakea Supercluster. We contemplate the Great Attractor's pull and our place in this immense heaven.

Confront the boundaries of the observable universe and ponder the mystery of what lies beyond. This video is not just a journey through space but a journey of perspective. Join us in marveling at the universe's grandeur and our humble place within it.

It’s 4am, and the big test is in 8 hours. You’ve been studying for days, but you still don’t feel ready. Should you drink another cup of coffee and spend the next few hours cramming? Or should you go to sleep? Shai Marcu defends the latter option, showing how sleep restructures your brain in a way that’s crucial for how our memory works.
