Which of the inhabitants of our planet holds the record for time travel? Russian cosmonaut Gennady Padalka spent a total of 878 days in orbit, a world record. At the same time, he can be considered the owner of another record - the longest time travel among the inhabitants of our planet. According to the theory of relativity, the greater the speed at which an object moves, the more time slows down for it. It is calculated that thanks to space flights, Padalka is 1/45 of a second younger than if he had remained all the time on Earth. In other words, the astronaut returned from orbit to a time point 1/45 of a second later than expected under normal conditions.

When advertising watches, the number of stones in them is usually mentioned as a guarantee of their quality. What are these "stones" in the clock and why are they there? We need clocks (wrist, wall, etc.) if they run accurately and do not break constantly. On average, there are about two hundred and eleven different parts in a watch, and, obviously, this is a very complex mechanism. Let's see what makes the clock go and what role stones play in this. The mechanical energy necessary for its movement is obtained from the mainspring, which is a coiled steel tape, in the unfolded state, having a length of about sixty centimeters. When you wind up your watch, you wind this spring tightly. From the mainspring, energy is transferred through a system of wheels called a gear train to a wheel called a balance. This system of wheels moves the clock hands around the dial. The balance performs the same functions in a wristwatch as the pendulum does in a wall clock. This is the heart of the clock, regulating its course. Inside the balance there is a hair spring, which is a steel wire coiled into rings, thin as a hair. From half a kilogram of steel of the desired brand, you can make as many as 12 kilometers of such wire! Along the edge of the balance are small screws made of steel or gold. Their position and weight regulate the speed of movement of the clock hands. They are so small that as many as twenty thousand of these screws can be placed in an ordinary thimble! There is also a starter wheel in the watch, which, connecting with the balance, makes it move. It regulates the movement, and it is from it that the sound that we call "ticking" comes from. We mentioned the various wheels that are constantly moving in the clockwork. They are located on rods, and the constant movement of the wheels causes friction. In order not to wear off at the same time, the rods are mounted on tiny precious stones, such as ruby, sapphire or garnet. These are the watch stones. The more stones, the less likely it is that the forces of friction will wear down the moving parts of the watch, causing the watch to "lagging behind".
