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.

Say no to abuse of basic human rights. Let's paint Russia in rainbow colours and tell Putin the world supports equality.

well deserved.
 
A huge congratulations to #DaftPunk for winning album of the year!

The #Grammys  was certainly a night to remember with incredible performances from Daft Punk, Pharrell and Stevie Wonder, Macklemore, Ryan Lewis and Madonna, Kendrick Lamar and Imagine Dragons and even Beyonce and Jay Z. Which was your favorite performance?

In mathematics, a Fourier series (English pronunciation: /ˈfɔərieɪ/) is a way to represent a wave-like function as a combination of simple sine waves. More formally, it decomposes any periodic function or periodic signal into the sum of a (possibly infinite) set of simple oscillating functions, namely sines and cosines (or complex exponentials)

So every other camera application that DOESN'T crash is fine; but the one that does blames Google?

Funny. Says the developers that can't even code a properly working tablet UI after having months to do so with months of complaints. I still get rotated pictures and I still get a forced portrait mode which rotates the picture, forcing me to use landscape.

This is the first time that I've purchased/eaten from this particular location, and keep it mind it was after hours where the lobby was closed. The service was "OK" and I really didn't expect much on that end. However the food that I ordered was borderline cold, the sour cream was packed into one side on ALL four food items, and there was barely any meat in it damn thing so I really paid for air. Honestly the worst I've had at any Taco Bell thus far.

Pricey location, however I've received nothing but excellent service from the folks that work here both times I've visited and gotten piercings. Staff is professional, knowledgeable, and great at what they do. Good atmosphere as well. Whenever I'm around the 757 area, they are my first choice.
