Why is a collection of songs called an album?

On early phonograph records, due to the large thickness of the track, one side could hold only a few minutes of music. A big concert was sold recorded on several records in boxes similar to photo albums. Therefore, collections of songs began to be called "albums" - the name remained even when, thanks to technological improvements, it became possible to fit these collections on only one plate.

What is Einstein's Theory of Relativity?

When this theory was published, it was believed that no more than a dozen scientists around the world would be able to understand it! That is why we will not try to present its technical features. However, it will be useful to understand what Einstein did, what problems he studied.

We know that any movement is "relatively". This means that it can be measured in relation to something. For example, we are in a train car and look out the window. Watching objects flashing outside the window, we know that the train is moving. But in relation to the passenger sitting opposite you, you remain in place!

Therefore, the presence of movement can be determined in relation to something motionless. This is the first part of Einstein's theory. We can formulate it as follows: the movement of a body with a constant speed in outer space cannot be fixed regardless of other objects.

The second main tenet of Einstein's theory is that the only constant in the universe is the speed of light. We know its speed - about 300 km / s. But it is difficult for us to even imagine that this is a constant value. And here's why: if a car is moving at a speed of 000 km/h, this means that its speed with respect to a stationary observer is 100 km/h. If the first car overtakes the second, moving at a speed of 100 km / h, this means that the speed of the first is 60 km / h higher than the second. And if the second car goes towards them, their total speed at the meeting point will be 40 km/h.

So, according to Einstein's theory, if we measure the speed of a beam of light in the same way (for example, we move in one direction, and the beam of light in the opposite direction), its speed will remain unchanged - about 300 thousand km / s. This only gives a general idea of Einstein's theory of relativity. In addition, he explored issues related to mass and energy, ways of transition from one state to another.

Artificial leather for touch emulation 15.04.2024

In a modern technology world where distance is becoming increasingly commonplace, maintaining connection and a sense of closeness is important. Recent developments in artificial skin by German scientists from Saarland University represent a new era in virtual interactions. German researchers from Saarland University have developed ultra-thin films that can transmit the sensation of touch over a distance. This cutting-edge technology provides new opportunities for virtual communication, especially for those who find themselves far from their loved ones. The ultra-thin films developed by the researchers, just 50 micrometers thick, can be integrated into textiles and worn like a second skin. These films act as sensors that recognize tactile signals from mom or dad, and as actuators that transmit these movements to the baby. Parents' touch to the fabric activates sensors that react to pressure and deform the ultra-thin film. This ... >>

The Petgugu cat litter bowl is designed for use with water-soluble litters and offers a range of additional ... >>

The attractiveness of caring men 14.04.2024

The stereotype that women prefer "bad boys" has long been widespread. However, recent research conducted by British scientists from Monash University offers a new perspective on this issue. They looked at how women responded to men's emotional responsibility and willingness to help others. The study's findings could change our understanding of what makes men attractive to women. A study conducted by scientists from Monash University leads to new findings about men's attractiveness to women. In the experiment, women were shown photographs of men with brief stories about their behavior in various situations, including their reaction to an encounter with a homeless person. Some of the men ignored the homeless man, while others helped him, such as buying him food. A study found that men who showed empathy and kindness were more attractive to women compared to men who showed empathy and kindness. ... >>

The cage backs up 06.07.2006

American biologists from the Foundation for Medical Research forced the clawed frog cell to reverse the process of division.

The cell, which has already almost split into two, seems to "change its mind", and both halves merge again. So do the chromosomes, already lined up for distribution to two future cells. They again return to a single core. This result is achieved by targeting two proteins that control cell division.

In the future, the method of stopping cell division may be useful in the treatment of cancer.
