Keep Champagne Bubbly (Hint: A Spoon Doesn't Work)

One booze hack that's been making the rounds for years is that inserting a spoon by the handle in a champagne bottle's neck will preserve its carbonation. This is one of those tips that I wish were true. Champagne is a great thing to have around on a special occasion, and it seems a shame to pour any leftovers down the drain once its lost its fizz. While there's lots of anecdotal evidence surrounding this trick, Harold McGee and Stanford University chemist Richard Zare debunked this myth as d...

News: Airline Offers Frequent Flyer Miles to Hackers

One more business has decided that rewarding hackers to find flaws in their computer systems is a wise investment! As you know, a number of software companies offer bug bounties, and some of these can be quite lucrative.

News: Rocket Power Your Lazy Boy

Since the days of Archytas, rocket propulsion has been the Holy Grail of aeronautics. Thanks to Galileo's inertia, Newton's laws of motion, and the "father of modern rocketry," Goddard, space is not a complete mystery anymore. Rocket-powered aircrafts have evolved from the first liquid fuel rocket in 1926, to the Soviet R-7 which launched Sputnik, to NASA's Saturn V that propelled Apollo 11 to the moon. Today, even billionaire tourists can enjoy space, like Microsoft's Charles Simonyi and Cir...

How To: Graph square root functions & inequalities

On Yay Math, Robert Ahdoot, founder of Yay Math, will show you some square root functions and some inequalities. He begins with the problem y=x². Then he makes a sketch with two intersecting lines in a t shape. The problem is illustrated by a curved U shape, the U's bottom resting on the horizontal bar, which represents x, while the center takes the vertical line. The vertical bar represents y. This U is directed up because the x² is a positive number. If the number were negative, the U would...

NR50: The Influencers to Watch in Augmented & Mixed Reality

When building anything of a social nature, be it a local roller derby or softball team, a club dance night for chiptune, or building new technology markets, the community around those ideas are an important factor in helping these things not only come into existence but to grow into something that enlightens everyone involved. The community around an idea can actually make or break these new ventures — and this applies to augmented and mixed reality as well.
