The brachistochrone
This animation is about one of the most significant problems in the history of mathematics: the brachistochrone challenge.
If a ball is to roll down a ramp which connects two points, what must be the shape of the ramp’s curve be, such that the descent time is a minimum?
Intuition says that it should be a straight line. That would minimize the distance, but the minimum time happens when the ramp curve is the one shown: a cycloid.
Johann Bernoulli posed the problem to the mathematicians of Europe in 1696, and ultimately, several found the solution. However, a new branch of mathematics, calculus of variations, had to be invented to deal with such problems. Today, calculus of variations is vital in quantum mechanics and other fields.

If you look at the fact that you have a roof over your head, food to eat, that you are young and beautiful and live in a peaceful land, then no, you have nothing to be sad about. But the fact is, we are not only a physical body, we have souls too, and sometimes our souls get sick. If you break a leg you don’t just say ‘I have no reason to have a broken leg’ and ignore it; you seek help. It’s the same when your soul gets hurt. Don’t apologize for being sad.

I live in a really bad neighborhood and my friend came over and we heard gun shots and she was like “ooh fireworks” and I just smiled and nodded.

Anonymous asked
what actually happened at dashcon to make it so awful? ive seen lots of stuff making fun of it and complaining, but nothing explaining why

It is one of the biggest errors in world history and here’s why:

  • Although starting in the middle of summer with a few small battles, it eventually dragged on for almost six months into a brutal winter
  • The Russians’ scorched earth policy surprised the French and made the French’s advances much more treacherous and costly
  • Napoleon’s thirst for a full victory was impossible to satisfy because the Russians refused to engage in any prolonged battles, instead wisely choosing to use guerrilla tactics to decimate an already broken, famished, and sickened French Army
  • Over 17,000 French troops lost their lives each month during the disastrous campaign
