Read Bykov

On the waves of "Freedom" for the first time many of the works were made in the author’s reading of the writer and in the implementation of the speakers.Now teachers and students, priests and political prisoners, poets and politicians will be read on the air their beloved page. About the latest transfer knows Sergei Navumchyk.Navumchyk: Throughout June, every day, Freedom on the waves will sound Bykovskaya lines. They will read a variety of people — and close friends of the writer, for example, and Gennady Ryhor Baradulin Buraukin, and those who never beheld the living Bykov. We asked each to

Tamer radio — Popov

MARCH 16, 1859 in the village. Turinskie Mines Verkhotursk district of the Perm province (now Yekaterinburg Krasnotur'insk region) in the priest's family born Alexander Stepanovich Popov, physicist and electrical engineer, inventor of the radio.

May 7 (April 25, Old Style) entered the history of world science and technology as the birthday of the radio. It was on this day in 1895 at a meeting of the Russian Physical and Chemical Society Russian physicist Alexander Stepanovich Popov made a presentation and demonstration he created

Why do some earthquakes cause tsunamis and others do not?

Why do some earthquakes cause tsunamis and others do not? It is interesting

Magnitude 9 earthquake off the coast of Sumatra on 26 December 2004 caused a powerful tsunami, which took place around the Indian Ocean. March 11, 2011 in the east of the Japanese island of Honshu, an earthquake measuring 8.9, provoked a tsunami 10 meters high. U.S. National Weather Service warned of the danger of over 50 countries and territories within the Pacific Ocean. In particular, the tsunami waves have left their mark in the Hawaiian Islands. So why do some earthquakes cause tsunamis and others do not?

Storm winds and strong waves crash around Ireland and the UK

Storm winds and strong waves crash around Ireland and the UK Natural Disasters

Storm to the north of Great Britain caused a storm winds, cold rains and waves in the Irish Sea. From 27 to 28 November strong waves was overturned cargo vessel "Swanland". As a result of the collapse of the two survivors, one was killed, five fate remains unknown.

Sea waves fall on the shore near Workington Cumbria, destroying everything in its path. In Scotland, because of the strong storm winds closed roads in mountainous areas, and ferry flights canceled. According to the weather station force wind gusts

Efficient use of solar energy

Efficient use of solar energy Facts

Some devices, like calculators, use small solar panels for their work. But to provide the energy for all humanity daily needs would need a huge solar panel. Everything modern technology can convert only 7% of the optical solar waves into electricity.

Scientists at Tel Aviv University Faculty of Physical Electronics, together with the Centre for Renewable Energy are developing solar panels based on nano-antennas instead of semiconductors. Adapting classic metallic antennas to absorb light waves at optical frequencies, will significantly increase the number of ready-to-use energy.

Radio — and optical waves are electromagnetic energy.

The Japanese earthquake has caused waves in Norway

July 2, 2013. An earthquake biggest load assumes a region located near the epicenter, and sometimes a push, you can register and at a great distance. But seismic waves emitted by an earthquake, in fact diverge around the world several times and bend around the globe, turning the planet into a large bell ringing. The stronger the earthquake, the louder he "calls." A earthquake magnitude 9.0, which occurred off the coast of Japan March 11, 2011, was a very, very powerful.

Seismometers are

Especially in shallow water by the tsunami explained

October 1. Scientists from the University of Colorado at Boulder have used mathematical methods to the characteristics of the waves appearing in the shallow water before the tsunami, and found that their characteristics depend on what kind of force wave will cover the island.

Total found two distinct types of waves — X-shaped and U-shaped, so called because of the form that takes water mass.

Through his research in the natural environment, the scientists saw that the conventional direct waves in the interaction form a different type of waves, X-or Y-type. Thus, if closer to the coast during the

Coast of Chile sweeping 7-meter wave

July 5, 2013. Coast of Chile sweeping 7-meter wave. Hundreds of kilometers of coastline of Chile overwhelmed the huge waves. Local residents say they see it for the first time.

On the Pacific coast of Chile struck huge waves. Locals say this has never seen.

Local resident: "Yes, we used to be and high waves, but that such a huge, five meters, is — for the first time."

In some places the waves reached a height and seven meters. The reason for the abnormal phenomenon — the tide coupled with strong winds.

In the city of Vina del

Nocturnal heat waves will become more likely to visit the Pacific Northwest

July 25, 2013. Recently, a study on heat waves, brought quite interesting results, showing that the amount and intensity of such events will increase in the north-western Pacific countries, not during the day and at night.

Experts from the University of Oregon and Washington have documented 15 instances of "night heat waves" in the period from 1901 to 2009. Ten of them came after 1990, 5 were from the short period from 2006 to 2009. While the study materials were prepared for the press, became aware of the occurrence thereof, even a heat wave at the end of June this

Samara, scientists have discovered a formula for plasma aerodynamics

A team of scientists from the Samara branch of the Physical Institute. PN Lebedev Physical Institute (LPI SF) got the formula simulations of shock waves in the atmosphere, which will make a significant contribution to the development of a new science — plasma aerodynamics.

Currently, scientists need to thoroughly understand the mechanisms of propagation of the shock wave and the changes in non-equilibrium environments. The most important task of the application of such research is to create a so-called "plasma membrane" of
