How to read the scales of Libra?

One of the twelve constellations is called Libra. It should be said that it is generally written as Libra. Originally, this is nothing special, but people usually call it Libra. In fact, the word "scale" has only one sound: Cheng (4 tones).

It doesn't matter whether you read "Ping" or "Cheng". You can read either one, but it depends on which word you read. "Scale" is not a disyllabic word, but only one sound, which is "Cheng", such as the ending song "There is a Scale between Heaven and Earth" in the TV series "Prime Minister Liu".

There may be several reasons why so many people mispronounce such a not uncommon word:

1, read the word and read half. On the right side of the word "scale" is the word "flat", so I pronounce it flat.

2, misled by icons. In many books or web pages about constellations, there are icons of various constellations. The icon of Libra is a balance, so Libra is regarded as a balance. In fact, "balance" is also a kind of "scale".

3. pass it on. Most people who don't know the truth say so, and others follow suit.

Interpretation of International Standard Chinese Dictionary;

weigh

Instrument for measuring weight: city ~. Pounds. ~ tuo.

Zheng code:, U: 79E4,: B3 D3.

Number of strokes: 10, radical: He, and stroke sequence number: 3123414312.

The scale is also called "weighing". Weighing instruments or all instruments that measure the weight of unequal arms are called scales, or lifting lever scales that measure the weight of weighed objects by looking at scales, or scales for short. Unequal-arm weighing instruments existed in the Warring States period.

When did the domestic steelyard begin? There is no conclusion yet. The unearthed bronze balance bar of the king of Chu has a scale of ten equal parts, which is supposed to be a sign of hanging heavy objects in different parts during weighing, and it is likely to be a weighing instrument that appeared during the transition from an equal arm scale to a steel scale. After the eastern Han dynasty, it evolved into a scale that looked at the weight from the scales.

The stars in Libra have been recognized since ancient times, but Ptolemy did not regard them as independent constellations. In Ptolemy constellation, the star of Libra belongs to Scorpio's claw, Libra α is Scorpio's north claw, Libra β is Scorpio's south claw.

People regard the stars as a steelyard, symbolizing fairness. However, it was not until Caesar's time in the 1 th century that the Romans discovered that the sun moved to this constellation just before and after the autumnal equinox, so they drew it independently.

Now, due to the precession of the earth, the autumnal equinox has moved to Virgo in the west. In the present era, the sun runs from 1 65438+1October1to165438+/October 23rd every year.

Constellation background

Libra (Latin: Libra, astronomical symbol:) is one of the zodiac signs and one of the Ptolemaic constellations.

Located between Virgo and Scorpio, this constellation has more than a dozen galaxies visible with 8-inch (20 cm) or larger telescopes. The four brightest stars in the constellation, α, β, γ and σ form a quadrilateral, and β and the spring triangle form a big diamond. Libra beta, whose middle name is "zubeneschamali", is the only star with green visible to the naked eye all day.

Libra alpha star "zubenelgenubi" is a binary star, which is composed of α 1 with brightness of 5.2 and α2 with brightness of 2.8, and appears blue and white.

4. Libra δ (Pleiades Zeng Yi), also known as South Australia, is an eclipse binary star like Perseus β. Eclipsing binary stars are two stars that periodically eat each other. From the perspective of the earth, their brightness will change. The magnitude variation of Libra δ is +4.8 to +5.9, and the light variation period is 2.3 days.

Interpretation of Libra's Ci Hai

Tiancheng Palace is the seventh house of the zodiac. The zodiac is from 180-2 10, originally in Libra, hence the name. But due to precession, it has moved to Virgo. Every year around September 24, the sun comes to the palace, and the autumn equinox season.

The legend of the origin of Libra:

In ancient times, both human beings and gods lived on the ground and lived a peaceful and happy life together. However, human beings are getting smarter and smarter. They not only learned to build houses and pave roads, but also learned bad habits such as intrigue and bullying, which made many immortals unbearable and made human beings live only in heaven.

But among the gods, there is a goddess who represents justice. She is not discouraged by human nature, and still lives with human beings. However, mankind is getting worse and worse, with wars and killing each other.

In the end, even the goddess of justice couldn't stand it anymore and resolutely moved back to heaven to live, but this doesn't mean that she has completely despaired of mankind. She still believes that human beings will realize one day and return to the kind and pure nature of the past.

The goddess of justice who returned to heaven met Poseidon by chance one day. Poseidon laughed at her foolish trust in human beings, and they immediately had a heated argument. During the debate, the goddess of justice thought that Poseidon had insulted her and had to apologize to him. Poseidon doesn't think so. It is said that the two men were deadlocked and sued Zeus.

This situation embarrassed Zeus, because the goddess was his daughter and Poseidon was his brother, so it was impossible to take sides. Just when Zeus was very worried about this, the queen made a suggestion in time, asking Poseidon to compete with the goddess of justice, and whoever lost would apologize to the other side.

The venue of the competition is located in Paradise Square, starting from Poseidon. Poseidon waved his stick at the wall, and beautiful water immediately flowed out of the crack. Then the goddess of justice turned into a tree with a reddish-brown trunk, green leaves and golden olives. Most importantly, anyone who looks at this tree will feel love and peace. At the end of the game, Haisai was persuaded to give up.

In order to commemorate this result, Zeus threw the scale he carried into the sky and became the present scale.
