Question: What I'm gonna find here?
Answer: There are times when I find very awesome things on the internet which end up teaching me a lot. I mostly take the screenshots of write down those things in my Text Editor. In this section, you'll find some nice stuff scrapped from the Internet! They will be random, meaningful, and knowledgeable!
9² = 81 → 8 + 1 = 9 45² = 2025 → 20 + 25 = 45 7777² = 60481729 → 6048 + 1729 = 7777
The software to create the black hole in the movie 'Interstellar' is a full implementation of Einstein's equations in 40,000 lines of C++, and rendered thousands of 23-megapixel IMAX frames on a 32,000-core render farm at about 20 core-hours per frame.
A further person pointed out (correction) - The geodesic equations are not Einstein's equations. The code for Interstellar only had to ray trace on a fixed analytical background spacetime (Kerr metric), rather than solve partial differential equations for the metric itself.In case you are curious to know more about it, follow -
