How were the elements formed?

The big bang created only two chemical elements, hydrogen and helium (and small amounts of deuterium and lithium). All other elements that fill the periodic table appeared only after the emergence of stars. In their depths, during thermonuclear fusion reactions, nitrogen, oxygen, carbon and heavier elements were gradually formed.

The evolution of large stars ends with their explosions, after which the elements accumulated in such stars disperse into space, pollute the clouds of interstellar gas, and in due course serve as the raw material for the emergence of new stars.

In the world in which we live, there is a constant processing of primordial matter - the Universe is enriched with heavy elements, and the lightest ones are becoming less and less. Our Earth and all living beings on it, including people, consist of chemical elements formed in the stellar depths.

Therefore, we are all, in a certain sense, children of the stars.

Why is the day of big sales and discounts in the US called Black Friday?

After Thanksgiving in the US comes Black Friday, when stores offer big discounts and break sales records. In a situation where both sellers and buyers are satisfied, the epithet "black" seems strange - it usually goes to days of extraordinary events. The fact is that the term was put into circulation back in the 1960s by the Philadelphia police. On this day, the complexity of their work increased many times due to huge traffic jams and crowds of people.

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 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. ... >>

Connected car from Bosch 12.05.2016

Bosch, a provider of technology and services to the automotive and industrial sectors, unveiled its vision for the future of connected cars at a conference in Berlin.

The company showed the cockpit adorned with a large surface monitor on the dashboard with space for additional monitors running down from the center of the console to the cup holder. The screens work in sequence to warn of potential threats (pedestrians, cyclists, etc.), flash real-time traffic and weather updates, offer an easy transition to automatic driving, and even convert into a video conference booth.

The car joins the Internet of Things with the touch of a finger, which allows the driver to remotely open the door of his house, for example.
