How many times is a modern telescope sharper than the human eye?

The more light "gathers" an optical device, the less bright and more distant objects it "sees". That is why telescope mirrors are getting bigger and bigger.

The working (effective) area of the main mirror of a telescope with a diameter of 8 meters is approximately 48 square meters, and the area of \u20b\u2,5bthe human pupil at dusk is approximately XNUMX square millimeters. The telescope will collect as many times more light as its area is larger than the area of the pupil, that is, approximately XNUMX million times!

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 ... >>

China starts building 6G networks 12.11.2019

In China, work has officially begun on the creation of telecommunications technologies of the sixth generation. Representatives of ministries and research institutions held a meeting to establish a national 6G technology research and development group.

It comes just days after China's top three carriers announced they are rolling out 5G mobile services across the country.

Countries around the world are racing to deploy next-generation wireless networks that can deliver data rates at least 20 times faster than 4G, paving the way for new applications including self-driving cars and augmented reality.

In recent months, technologies related to 5G networks have become a hotbed of conflict between the US and China. The US government has blacklisted Chinese company Huawei Technologies, the world's largest supplier of telecommunications equipment, preventing it from accessing US goods and services. In addition, under the pretext that Huawei equipment could be used for espionage, the United States tried to convince its allies to exclude the Chinese company from participating in the rollout of 5G networks.
