The potters wheel is one of the oldest inventions of man. He is already more than seven thousand years old! The ancient Egyptians even believed that the god Khnum fashioned the first people precisely on the potters wheel. In the beginning, the circles were very simple. A disc was put on a large stick, and a lump of clay was placed on the disc. With his left hand, the potter rotated this disk, and with his right hand he gave the clay the desired shape.

Sculpting with one hand was not very convenient. Therefore, after some time, a device consisting of two disks appeared. So that they began to rotate, the potter pushed the lower disc with his foot. And his hands were free! A similar potters wheel is used even now if you need to make a particularly beautiful and elegant dish.

One Star Memoirs


- Here you say: the Sun, the Sun ... And your Sun is just a young star, greenhorn. Just 5 billion years old!

And I’ve been living a trillion years. I've seen everyone. So you know that stars are born in flocks? Yes, yes, hundreds of young stars appear in one place at a time. It seems to you from Earth that all the stars are white. Haha And we are very different! It all depends on the temperature of the star. The hottest glow blue and white. The colder ones are orange and yellow. Red and brown are the coldest. There are giants and dwarfs among us - small stars. I’m a red dwarf and proud of it!

When the stars grow, they gradually fly apart. So my brothers and sisters ran away to where. But there are star girlfriends - do not spill water. They even came up with a nickname for them: "double stars." They revolve around each other, making them stretch like pears! And sometimes they merge and turn into one asterisk. And some stars like to joke. You look at her: a star is like a star. Just turn away, and she rrr-times - and swelled up like a fish-hedgehog. Then rrr-times - and was blown away again. And so several times a day. Scientists nicknamed these little rascals "pulsars." What are they really pulsing back and forth?

There are still spinning tops. They are of respectable age, and spinning like small ones. Is this normal: in one second do a thousand revolutions around yourself ?! Scientists of these spinners are called "neutron stars." They are very strange. Themselves small - 15 kilometers wide, no more. And weigh ... scary to imagine! A teaspoon of this star's substance weighs - like several planets! In the end such a star will explode! The remnants of the planet scatter across the galaxy. And there is as much light and heat released as your Sun has not heated for 10 billion years !!! Here are the miracles we have here!

Regards asterisk.



Tonti and Molly were sitting on the couch and dangling their feet, when suddenly it came from under the sofa:

"Oh-ho-stinkers! .."

Friends first jumped to the ceiling and then rushed to look under the sofa. Something mysterious shone there. "Who is there?" - Tonti asked bravely.

- I'm great! Famous! Great! And ... a forgotten button!

Tonti put his hand under the sofa and pulled out a small iron button with two holes.

- Not so great you are, - said Molly.

The button even trembled with indignation.

- Yes, you know what ancient ancestors I have!” in India they found a button that is 5000 years old! and we are very similar. She also has two holes! My great-great-great-great-great-grandmother adorned the tunics of the ancient Greeks and Romans. True, it was more like a brooch. My ancestors became real celebrities in the Middle Ages. Buttonsomania began. In Turkey, a narrow strip of fabric was tied in a tight knot - and the button turned out. In Europe, my relatives were sewn onto clothes not only in order to fasten them, but also just for decoration. The buttons were made of metal, ivory, leather, gems, gold and silver. One French king ordered 13,600 gold buttons for his costume. And the other one put almost 2000 diamonds on the button decoration!

In Russia, the ancient buttons looked like a small weight - a ball with an eye. They were considered a great value and inherited. Button factories appeared in the 19th century. And we, buttons, became available to everyone. And what would you do without us? How would they button their shirts and coats?

- May I sew you on your shirt? - Molly said respectfully. - And I’ll tell everyone how famous you are.

- Urrra! - rejoiced button.
