The laws of physics

In particular, mechanics proved that physical laws apply not only on Earth and in space. Newton's famous discovery, the three laws of motion:

1. law of motion - Law of Inertia
2. law of motion - power law
3. law of motion - the law of action and reaction

Further, discovered the laws of universal gravitation (Newton's law of universal gravitation). Classical Mechanics is still based on it established concepts mass inertia forces and interactions. He discovered many laws relating to the special nature of the motion of the planets move in an environment with resistance, rotating fluids etc.

First Kepler's law
The planets revolve around the sun in an elliptical path, in which one common focal point is the sun.

Second Kepler's law
Content areas circumscribed průvodičem planet (line connecting the planet and the Sun) at the same time are the same size.

3rd Kepler's law
The ratio of the squares of the periods of two planets is the same as the ratio of the cubes of their semi-major axes (intermediate distances of the planets from the Sun).

Constellation

The constellation is an area on the sky with clearly defined boundaries. Often called constellations and the apparent formation in the sky (alignement), which consists of a link between several brightest stars. These people in ancient times resembled various gods, animals etc., According to which it was named. In every civilization has a different constellation system.

The sky was the International Astronomical Union (1925) finally established just 88 constellations. Of these, 48 still bears the name of ancient times, has been described in Ptolemy's Almagest. The names of these 48 constellations related to Greek myths. Primarily cover the northern firmament. They must Taurus, the Great Bear, Orion, Andromeda and others. Greek civilization probably took this constellation of Mesopotamia or Egypt. Traditional constellation is located on that part of the sky that was visible from 35 degrees north latitude in the time around the year 5000 BC. The shapes may have been known much earlier (as picture constellation Orion was also found bones from the Stone Age).

The constellation of the southern sky arose later. The authors of their names and shapes are explorers and scientists, who at the time of Discovery reached the southern hemisphere, where they could observe for the first time this constellation and who needed to orientation. Description of the southern sky finished in the 18th century by the French astronomer Nicolas Louis de Lacaille. He introduced a constellation example: Triangle, Microscope, pump and so on.

Observations

Constellations today help you navigate the sky. If we live in the northern hemisphere, then we can throughout the year to observe the constellations north, while the south we remain largely hidden. It is due to the fact that the earth's axis in space is almost not moving towards a distant stars remains at rest (still pointing to Polaris or North Star). Southern constellations are then covered with earth incessantly body.

Constellations in radius around the world pole called. Circumpolar constellations are visible from the site throughout the year. The radius of the circle is the same as the latitude of the observation place. An observer at the pole constantly sees the same part of the sky. Conversely, an observer standing near the equator by a single day could theoretically see the whole sky with all its stars. Polaris would constantly seen just above the horizon.

Practically, however, to never happen, since the day we can observe the stars and a half the sky, which is the sun is hidden in its glow. We have to wait many months for the Earth in its orbit around the sun moves. So we open views of the constellation until now hidden. That is why we often talk about spring, summer, autumn and winter sky.

Division

Constellations are divided into so-called. Constellation families:

• Family Great Bear
• Perseus family
• Hercules family
• Zodiacal constellation - lies on the ecliptic.
• Orion family
• Celestial Waters
• Bayerova family - first described by German astronomer Johann Bayer in 1603
• La Caillova family

Constellation

Individual stars constellation connects only the human imagination. Sun, like the other stars that we see the naked eye in the sky belongs to our galaxy, but are otherwise independent. Side by side we can see the stars that resemble each other at all, which divides the abysmal distance that move in different directions. Transience shapes constellation is relatively "agile": about 30 thousand years. Then the stars apart in the sky moves away and pattern collapses.

An exception is the so-called open clusters and cluster movement. If they are close enough, can form a majority and form the bulk of the entire constellation. Hyades in Taurus and most of the stars of the Big Dipper such clusters are.

Today, marking the constellation is not just the shape of a few stars in this form associated. Each one constellation has clear boundaries and becomes essentially a kind of territory, one covered everything in this area can be observed in outer space (solar system body when viewed from Earth over time can translate into different constellation).

Interesting facts about the constellations

The largest constellations across the sky used to ship Argo (legendary Argonauts). This large constellation, however, was in the 18th century divided into keel, poop, Kompas, dove, flying fish and sail. Today it is the largest constellation Hydra. Only one constellation is split. Had he was formerly part of Ophiuchus. After their separation Ophiuchus the Serpent severed snake and became a two-part constellation. Two of its parts can be distinguished as a snake's head and tail of the snake. But this is only the constellation Serpens. Big Dipper constellation is not. This is a group of stars that belong to the constellation Ursa Major. Small car is officially appoints Czech Ursa Minor.

Horoscopes

Horoscope is an astrological chart or diagram (figure) showing the position of celestial bodies for the moment a particular place on Earth. The origin of the word is derived from the Greek horoskopos (= sign of the times).

Babylonian priest-astrologers are considered to be the first one to split the annual pilgrimage of the Sun among the twelve zodiac constellations, or rather the astrological sign for 30 degrees. They are also ascribed to build the first horoscopes. The oldest extant horoscope is a diagram of r. 410 BC. It is the horoscope son Babylonian monarch Šuma Usa, who was born on 29 April 410 BC.

Around the year 200 BC. In Hellenistic astrology suddenly pushed the new production system horoscopes, which significantly expanded the original system of Babylon. The new system appeared suddenly and stabilized during half a century, leading to the conclusion that it was probably the work of an individual (which can be considered as the legendary Hermes Trismegistus) or unknown small astrological school. This system has stabilized compilation horoscopes virtually in the form of what has been preserved (introduced a system of houses, aspects, used seven classic astrological planets, etc.), Although in later Arab and Western astrological traditions underwent significant modifications.
