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.

This is the inFORM Dynamic Shape Display from MIT. And it may be gypsy magic.

There’s a Kinect camera watching the demonstrator, tracking his movements, when are then transferred to a computer, which sends to an array of pillars, which move up and down accordingly using actuators.

You can use it to transfer the actual movements of your hands, so you could remotely handle objects, like in the first 2 gifs, or you can use it for 3-D modelling like in the other two, like how he uses gestures to pull a cube of the table.

Basically it’s the crazy map from the first X-Men, or the first generation of Fitz and Simmons holotable in Agents of SHIELD. Imagine what you could with this, remote handling of hazardous materials, actually 3-D movies, conference calls that could actually project what you’re doing.

The future is awesome.

But you can call him Tang.

This is his legal name
