radioactive material

The globe has a red-hot core, but the warmth that every inch of the earth's surface receives from its mineral wealth, in 5000 less than the heat produced from the sun. At recess for every 33 m into the earth's crust at an average temperature rises by one degree. We can assume that this temperature rise occurs only in a relatively thin layer of the crust (deeper than 100 km), which contains radioactive material.

Cosmonaut Yuri Malyshev

Cosmonaut Yuri Malyshev, in "Technique - Youth" (1981.11) said: "As for the UFO, not a single person in the world probably can not tell what it is. To deny such things is impossible, because their witnesses were thousands of even tens of thousands of people. But the physical nature of the phenomenon remains a mystery. "

the universe

Its emergence, existence and development are also due to some fundamental properties of the universe, expressed, for example, constants that characterize the gravitational, electromagnetic, strong and weak interactions. Scientists believe that the values of these constants, such as the gravitational constant, different from the observed, life in the universe simply could not exist.

the solar system

In this icy blend of enclosed sand dust, stones and large pieces of metal. All these materials are included in the interstellar cloud from which the Sun and planets formed. Comets - the most spectacular and most mysterious bodies of the solar system. So they were throughout the history of mankind, such remain to this day.

the red planet

When in 1977 the American astronomer Asaph Hall discovered the two satellites, he gave them Greek names Foos and Deimos, which are translated as "fear" and "horror". Fear and dread - the eternal companions of war, but who can scare the two tiny satellites are harmless? Many science fiction writers inhabit the red planet warlike monsters or humanoids seeking to destroy the earthlings.

the sun

In the first case, the mass of the protoplanetary cloud was to be a significant fraction of the mass of the sun, and the composition of the giant planets should coincide with the sun. Neither one nor the other does not match the facts. Recent studies have shown that in the nuclei of Jupiter and Saturn, apparently, there are elements heavier than hydrogen and helium make up at least 5-6% of the planet's mass.

Broadcom Corp.

The company Broadcom Corp. (BRCM), a manufacturer of chips for mobile devices, Apple Inc. (AAPL), has reached agreement to purchase the NetLogic Microsystems Inc. (NETL) for $ 3.7 billion, shareholders will receive NetLogic $ 50 per share - a 57% higher than the closing price on September 9 portfolio management.

Purchase this company expands its product line Broadcom, but also increases the competitiveness of the market where its main rival is Qualcomm Inc. (QCOM). Shares rose to NetLogic $ 49 today (Friday closing price - $ 31.91 on Nasdaq) stock market technical analysis.

stars and galaxies

By the way, do not run up the stars and even individual galaxies and galaxy clusters. Coming from stars and galaxies we relate to each other by gravitational forces and form a stable structure. Moreover, the direction in which neither see, from galaxy clusters scatter the earth with the same speed, and it may seem that our galaxy is the center of the universe, but it is not.
