Snakes traveling between walls that are spaced varying amounts apart

…That sentence is feels wrong, but anyway…

I just stumbled across this video again that I'm pretty sure I shared last year, but its still a cool demonstration of the dependency of a pendulums period on its length.

>>The length of time it takes a ball to swing back and forth one time to return to its starting position is dependent on the length of the pendulum, not the mass of the ball. A longer pendulum will take longer to complete one cycle than a shorter pendulum. The lengths of the pendula in this demonstration are all different and were calculated so that in about 2:40, the balls all return to the same position at the same time – in that 2:40, the longest pendulum (in front) will oscillate (or go back and forth) 50 times, the next will oscillate 51 times, and on to the last of the 16 pendula which will oscillate 65 times. Try counting how many times the ball in front swings back and forth in the time it takes the balls to line up again, and then count how many times the ball in back swings back and forth in the same time (though it's much harder to keep your eye on the ball in back!)

Chinese billionaire Liu Yiqian, who doesn't exactly struggle to afford a plane ticket, can now likely fly free, in first class, with his whole family, anywhere in the world, for the rest of his life.

What the heck kind of fantasy world are 49% of Americans living in?

Terrorism in the United States
How likely is it that there will be further acts of terrorism in the United States over the next several weeks — very likely, somewhat likely, not too likely, or not at all likely? How worried are you that you or someone in your family will become a victim of terrorism — very worried, somewhat worried, not too worried, or not worried at all?

A guy walks around with a 2013 Macbook

Its running a recurrent neural network that describes the scene in front of the webcam…in real time.

For some examples of what this sort of neural network can do, go here: (http://cs.stanford.edu/people/karpathy/neuraltalk2/demo.html). You'll find a bunch of images with captions wrote by a computer.
