If an enormously heavy object has to be moved from one spot to another, it may not be practical to move it on wheels. Instead the object is placed on a flat platform that in turn rests on cylindrical rollers (Figure 1). As the platform is pushed forward, the rollers left behind are picked up and put down in front.

The Unbearable Beauty of the Milky Way's Hidden Star-Birth Regions
Astronomers Bania and Loren Anderson of the Astrophysical Laboratory of Marseille in France have discovered about 450 hidden stellar nurseries in the Milky Way where rare colossal stars many times bigger than the sun are being born. The discovery doubles the number of known sites in the northern reaches of the galaxy where massive stars are born, said Tom Bania of Boston University, who estimats that there could be another 4,000 or so fainter massive-star birth regions awaiting discovery throughout the galaxy. Locating regions that form massive stars is like "putting pins on a map" to reveal the full structure of the Milky Way's spiral arms, according to Patrick Thaddeus of the Harvard-Smithsonian Center for Astrophysics in Cambridge, Mass. Gas and dust make the regions impossible to see in visible light, so astronomers have to resort to other wavelengths to trace them out. The new-found regions could provide new information about the chemical composition and evolution of the Milky Way.

How You Can Make Good Use Of Your Old Machines
Almost everyone reading the articles on this site will have spare computers languishing about. The rapid growth and improvements in hardware means that we cycle through a whole machine in only a few years. If you have spare machines and parts languishing about, you can put them to good use! In this article I have outlined some of the purposes your old hardware can serve. Like the article? Be sure to subscribe to our RSS feed and follow us on Twitter to stay up on recent content.

30 Habits that Will Change your Life
Developing good habits is the basic of personal development and growth. Everything we do is the result of a habit that was previously taught to us. Unfortunately, not all the habits that we have are good, that’s why we are constantly trying to improve.
Genetically modified food
Genetically modified foods (or GM foods) are foods produced from organisms that have had specific changes introduced into their DNA using the methods of genetic engineering. These techniques have allowed for the introduction of new crop traits as well as a far greater control over a food's genetic structure than previously afforded by methods such as selective breeding and mutation breeding.[1] Commercial sale of genetically modified foods began in 1994, when Calgene first marketed its Flavr Savr delayed ripening tomato.[2] To date, most genetic modification of foods have primarily focused on cash crops in high demand by farmers such as soybean, corn, canola, and cotton seed oil.
List of idioms in the English language - Wikipedia, the free encyclopedia - StumbleUpon
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" – and also 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" ).

1,000 Core CPU Achieved: Your Future Desktop Will Be a Supercomputer
Scientists at the University of Massachusetts Lowell laugh in the face of Intel's weedy handful of cores in its new CPU lineup: They've just squeezed over a thousand processor cores onto a single chip. We've heard a lot about the potential for future desktop-sized supercomputers, but more than anything else this research proves that in the not-too-distant future it's likely to be a reality. Interestingly enough, there's also a green angle to this idea: FPGA chips can be more power efficient than their competitors, and if less computer time is needed to process complex tasks, then the overall power consumption of computers using the tech could be impressively low. The advance was made by Dr. Wim Vanderbauwhede's team, who programmed an advanced chip called a Field Programmable Gate Array (FPGA).

How Mathematics Can Make Smart People Dumb - Ben O'Neill
Mathematics can sometimes make smart people dumb. Let me explain what I mean by this. I don't mean that it is dumb not to be good at mathematics. After all, mathematics is a highly abstract and challenging discipline requiring many years (decades even) of study, and there are plenty of very smart people who have little understanding of it, and little ability to use it.
