С using two mirrors you wanted to create your double, not reversed mirror. Well, you have achieved it... and even doubly so. After all, you have already seen not one, but two "seeming" images at once! Now there are three of you, and I don’t even know if it’s still convenient to refer to this small team as “you”.

How many reflections are in the mirror?

Having two mirrors, you can do many miracles of the same kind. If, for example, you put them at a right angle and put two apples in this corner, you will see eight apples. This is wealth! But do not rush to rejoice: only two will remain edible anyway, the remaining six are imaginary.

How many reflections are in the mirror?

You can put mirrors one against the other, and light a candle between them. In each of the mirrors, the candle itself will be reflected, and its reflection, and the reflection of the reflection ... Candles will line up in an endless string, going in both directions. Those closest to the middle will burn brightly, and the farther away, the weaker, weaker ... This is because some part of the light is absorbed by the mirrors.

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 ... >>

Petgugu Global cat litter 15.04.2024

Taking care of pets can often be a challenge, especially when it comes to keeping your home clean. A new interesting solution from the Petgugu Global startup has been presented, which will make life easier for cat owners and help them keep their home perfectly clean and tidy. Startup Petgugu Global has unveiled a unique cat toilet that can automatically flush feces, keeping your home clean and fresh. This innovative device is equipped with various smart sensors that monitor your pet's toilet activity and activate to automatically clean after use. The device connects to the sewer system and ensures efficient waste removal without the need for intervention from the owner. Additionally, the toilet has a large flushable storage capacity, making it ideal for multi-cat households. 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. ... >>

Quantum crystal to search for dark matter 05.08.2021

Scientists used quantum entanglement and time reversal in a crystal that was able to solve one of the biggest mysteries of the universe. A quantum crystal has been created with unprecedented sensitivity that could potentially be used to detect dark matter, the mysterious substance that makes up the vast majority of matter in our universe, a new study reports.

The revolutionary sensor was developed at the US National Institute of Standards and Technology (NIST) and is based on two very strange processes: quantum entanglement and "time reversal".

The tiny blue crystal, measuring just 200 micrometers, is ten times more sensitive than previous atomic sensors. It can tune into frequencies that scientists believe are emitted by hypothetical particles called axions, a leading candidate for dark matter, including a range of signals that are not detected by any other existing sensors.

Capturing a real axion could hold the key to one of the biggest unsolved mysteries in science: the nature of dark matter. Scientists know that dark matter exists because we can see its enormous gravitational effect on the "normal" baryonic matter that makes up our bodies, planets, and stars. But because dark matter doesn't emit any of the usual signals, it's difficult to observe and explain, even though there's five times as much of it as ordinary matter.

Despite this tantalizing application of dark matter, the team's ability to achieve quantum coupling between the mechanical and electromagnetic properties of a crystal is the study's "most important" finding, said Ana Maria Rey, a theoretical physicist at JILA, a joint institute of NIST and the University of Colorado at Boulder, co-author of the study.
