Scientists Discover The Oldest, Largest Body Of Water In Existence--In Space | Fast Company - StumbleUponScientists have found the biggest and oldest reservoir of water ever--so large and so old, it’s almost impossible to describe. The water is out in space, a place we used to think of as desolate and desert dry, but it's turning out to be pretty lush. Researchers found a lake of water so large that it could provide each person on Earth an entire planet’s worth of water--20,000 times over. Yes, so much water out there in space that it could supply each one of us all the water on Earth--Niagara Falls, the Pacific Ocean, the polar ice caps, the puddle in the bottom of the canoe you forgot to flip over--20,000 times over. The water is in a cloud around a huge black hole that is in the process of sucking in matter and spraying out energy (such an active black hole is called a quasar), and the waves of energy the black hole releases make water by literally knocking hydrogen and oxygen atoms together.
Almost everyone reading the articles on this site will have spare computers languishing about.

This is a list of notable idioms in the English language . An idiom is a common word or phrase with a culturally understood meaning that differs from what its composite words' denotations would suggest. For example, an English speaker would understand the phrase "kick the bucket" to mean "to die" – as well as to actually kick a bucket. Furthermore, they would understand when each meaning is being used in context. An idiom is not to be confused with other figures of speech such as a metaphor , which invokes an image by use of implicit comparisons ( e.g. , "the man of steel" ); a simile , which invokes an image by use of explicit comparisons ( e.g. , "faster than a speeding bullet" ); and hyperbole , which exaggerates an image beyond truthfulness ( e.g. , like "missed by a mile" ). Idioms are also not to be confused with proverbs , which are simple sayings that express a truth based on common sense or practical experience.
There is something special about the tricks and tips people come up with to turn old or useless objects into something fresh and useful. Turning an old gadget or piece of furniture into something completely new is a great way to extend its life, and here are some of our favorite conversions from the last year. Top 10 Ways to Turn Your Retired Gadgetry into the Technology of the Future With the rapid progression of technology each year, it's easy to accumulate a pile of obsolete gadgets that you just can't bear to get rid of.
If you've ever been convinced by a salesperson that you truly wanted a product, done something too instinctively, or made choices that seemed entirely out of character, then you've had an idea planted in your mind. Here's how it's done. Note: We've gotten a lot of emails about how to do this in specific situations. Although some of those situations have been legitimate, this post was written to teach you to detect these tactics rather than use them on others.
by Isaac Asimov I received a letter from a reader the other day. It was handwritten in crabbed penmanship so that it was very difficult to read. Nevertheless, I tried to make it out just in case it might prove to be important.

(PhysOrg.com) -- By suggesting that mass, time, and length can be converted into one another as the universe evolves, Wun-Yi Shu has proposed a new class of cosmological models that may fit observations of the universe better than the current big bang model. What this means specifically is that the new models might explain the increasing acceleration of the universe without relying on a cosmological constant such as dark energy, as well as solve or eliminate other cosmological dilemmas such as the flatness problem and the horizon problem. Shu, an associate professor at National Tsing Hua University in Taiwan, explains in a study posted at arXiv.org that the new models emerge from a new perspective of some of the most basic entities: time, space, mass, and length. In his proposal, time and space can be converted into one another, with a varying speed of light as the conversion factor.

The Elegant Universe: Part 3 PBS Airdate: November 4, 2003 NARRATOR: Now, on NOVA, take a thrill ride into a world stranger than science fiction, where you play the game by breaking some rules, where a new view of the universe pushes you beyond the limits of your wildest imagination. This is the world of "string theory," a way of describing every force and all matter from an atom to earth, to the end of the galaxies—from the birth of time to its final tick, in a single theory, a "Theory of Everything." Our guide to this brave new world is Brian Greene, the bestselling author and physicist.
