Water for the first time outside the solar

Astronomers have found water on the first planet outside the solar system, reports Reuters.Traces of water vapor were discovered by American scientists in an atmosphere of planet HD 209458b yupiteroobraznoy in the constellation Pegasus. According to one of the scientists made this discovery, finding confirmed the assumption of the existence of water on the set of planets of this type.Planet HD 209458b is from the Earth at a distance of 150 light-years away. It is very short - a length of only three and a half Earth days - the period of treatment around the world, so scientists could easily observe them.

10 most beautiful experiments in the history of physics

In five previous articles series “The Universe: Matter, Time, Space” (cont. Home see № № 6-11, 2006), using the analogy of the theater, we talked about how our world is arranged. Time and space are the stage on which play a complex and intricate plot lines and secondary main actors, as well as the invisible actors. Left to talk about with you - on the audience. We did not manage to top the spectacle, which began 14 billion years ago and appeared in the auditorium, most recently, the space-time scales - the past few thousand years. But we managed to understand a lot of theatrical effects, although much more remains to be seen. Not all representatives of the human race dedicate their lives to learning the laws of nature. Only a small portion of the year.

The barrier of the speed of light has finally been jump

Powerful impetus LIGHT passed through 6-cm «flask», filled with specially prepared cesium gas, - describes the course experience journalist «The Sunday Times», referring to the head doctor of the experiment Lidzhuna Wang. And devices have shown an incredible thing - while the bulk of the world with its usual speed tsezievuyu passed through the cell, some photons smart finish run to the opposite wall of the laboratory, located about 18 m, and note the location of a sensor. Physicists have calculated and verified: if particle-«toropygi» flying 18 meters over the same time, what normal photons passed through the 6-cm «flask», - hence, their speed at 300 times the speed of light! And it violates the sanctity of the Einstein constant varies very foundations of the theory of relativity …

Ares Vista best bet for Windows 7 users

December 25th 2009 | Posted by admin

Migrating all your software applications to a new operating system is always a pain in the *ss, especially when you’re talking about software that isn’t exactly mainstream.  P2P  (peer to peer) filesharing software such as Ares, Limewire, Bearshare and others are a good example.  They are kind of skirting the edge of legality, so are not supported by huge companies with big pockets that lawyers can go after.

As a result of operating in the legal gray zone by smaller companies, they often don’t have huge customer support staff and it can be difficult to get help with any snags trying to get it working.  So it is a huge relief to many fans of the popular Ares filesharing software to learn that moving to windows 7 doesn’t mean you need a new version – Aresvista works just fine.

To be sure, there is a version called Areswindows7, but it is really just an older version of Ares that has a new skin that uses the background colors and logos of windows7.  But it doesn’t have any new features, and in fact is missing some of the improvements Aresvista has, such as advanced node generation that ensures you won’t be left waiting for hours to make that initial connection to the network as so many users of the old Ares Galaxy are forced to do.

How to find an available domain name

August 15th 2009 | Posted by admin

When it comes to domain name registration and how to choose a domain name and find a domain
availability
, there are a very good and some very bad ones. I will show you how to find an excellent, keyword-rich name field should be register for your site or sell for a profit. Unfortunately, all one word domain names are long gone, but that does not mean they are not good ones left.

Today, however, things have changed for the better. There are many domain name registries like GoDaddy.com, Enom.com, NameCheap.com & Register.com to name a few. Ideally, you want a domain name that describes what your site or business is all about in as few words as possible containing the main keyword for your website or business. You can check your domainavailability through those sites. READ THE FULL ARTICLE >>

The sound of an electronic beam can help detect neutrinos

May 18th 2009 | Posted by admin

Russian physicists from VNIIFTRI SINP MSU and ITEP studied the acoustic effects from entry bunch of electrons in a substance. Interest in him is linked with the possibility of acoustic detection of ultrahigh-energy cosmic neutrinos.
Neutrino – trudnoulovimye most of the known elementary particles. Neutrino detectors (often called neutrino telescopes) are the big tanks of water (or ice, for example, IceCube in Antarctica), in which the many “electronic eyes” – photomultiplier. These detectors are so deep under the ground (under water, under the Antarctic ice), that no other particles, except neutrinos, they can not reach.

The vast majority of neutrinos pass a detector thoroughly, leaving no trace, and only rarely are they the same? Face? on matter, it turns into electrons. If the original neutrinos possess great energy, this electron generates electromagnetic downpour – the flow of electrons and positrons lesser energy. When driving through water, they are due to Cherenkov radiation, provides a flash of light, which registers and photomultiplier. After processing the data from all photomultiplier can restore full brightness of the flash, hence the total energy of a downpour, and the mean energy of the original neutrino.

This method of “catch” neutrinos have long-established and well-proven, but it has one major drawback (as with most experiments on registration of elementary particles): it uses very expensive equipment. Therefore, it would be interesting to find a different, simpler and cheaper way to record and evaluate their neutrino characteristics.

The unusual discovery made at low temperatures

May 18th 2009 | Posted by admin

Scientists from the Low Temperature Laboratory of Helsinki University of Technology investigated the heat transfer between two small metal samples, coupled superconductor. They found that at very low temperatures heat is distributed via electromagnetic radiation, reported EurekAlert.

Dr. Matthias Bags (Matthias Meschke), prof. Jukka Pekola (Jukka Pekola) and their colleagues studied the spread of heat in the micro-devices and nanorazmera based on conventional silicon chips, at a temperature of 0.1 degrees above absolute zero. During the study, scientists found that at very low temperatures heat is distributed through the superconductor through the electromagnetic radiation. At the same coefficient of thermal conductivity can only accept a strictly defined quantum values.

The state of inner core of land is not stable

May 18th 2009 | Posted by admin

Lianksing Wen (Lianxing Wen) from the New York University (State University of New York at Stony Brook) showed that the internal radius of the solid core of Earth grew over a decade for one – one and a half kilometers (0,98 – 1,75 km), at least in one area – under the central Africa. The basis for such finding were data from two earthquakes in 1993 and 2003 in the area of the South Sandwich Islands.

It turned out that the seismic waves generated by earthquakes and reflected from the surface of inner core in 2003, reached the three seismic stations in Russia and Kyrgyzstan on 39 – 70 milliseconds faster than in 1993.

This suggests a local increase in the radius of inner core in the area, located midway between the epicenter of the earthquake and seismic stations, which is under central Africa. It is believed that the growth of inner core occurs due to hardening of internal layers of the molten outer core.
