Who built the first model of the universe?

There are few scientific works in the history of mankind that would retain their value over many centuries. Among these is the "Almagest" of the Greek scholar Claudius Ptolemy (about 90-160).

He lived for a long time in Alexandria, which, although located in Africa, at the mouth of the Nile, served as the center of Greek culture for several centuries. There Ptolemy made astronomical observations.

What did Ptolemy "construct" in this "Construction of the World"? In it, he outlined a new system of the world invented by him. Like Aristotle, who lived four centuries before him, he came up with a geocentric system of the world, and for him the motionless Earth served as the center of the universe. But, unlike Aristotle, the Alexandrian astronomer did not recognize any crystal spheres. He had the Sun and the planets revolving around the Earth in empty celestial space.

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. ... >>
