Most often we are dealing with "honest" mirrors. They showed the world as it is. Well, maybe turned right to left. But there are teasing mirrors, crooked mirrors. In many parks of culture and recreation there is such an attraction - a "room of laughter". There, everyone can see himself either short and round, like a head of cabbage, or long and thin, like a carrot, or looking like a sprouted onion: almost without legs and with a bloated stomach, from which, like an arrow, a narrow chest stretches upwards and an ugly elongated head on the thinnest neck!

The guys are dying of laughter, and the adults, trying to keep their seriousness, just shake their heads. And from this reflection of their heads in teaser mirrors they warp in the most hilarious way!

teasing mirrors

The "room of laughter" is not everywhere, but teasing mirrors surround us in life. You must have admired your reflection in a glass ball from the Christmas tree more than once. Or in a nickel-plated metal teapot, coffee pot, samovar. All these images are very funny distorted and at the same time they are all reduced. This is because the "mirrors" are convex. Convex mirrors are also attached to the steering wheel of a bicycle, motorcycle, and by the driver's cab of a bus. They give an undistorted, but somewhat reduced image of the road behind, and in buses - also of the back door. Straight mirrors are not suitable here: you can see too little in them. A convex mirror, even a small one, contains a large picture.

There are sometimes concave mirrors. They are used for shaving. If you come close to such a mirror, you will see your face greatly enlarged. The spotlight also uses a concave mirror. It is it that collects the rays from the lamp into a parallel beam.

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. ... >>

Silicon optical transmitter 19.11.2020

Silicon photonics experts at the Optoelectronics Research Center (ORC) have demonstrated the first all-silicon optical transmitter that operates at 100 Gbps without the use of digital signal processing.

The optical modulator almost doubles the maximum data rate of today's devices, demonstrating the potential for low-power, low-cost all-silicon solutions. They avoid the complexity of manufacturing processes using new materials that are incompatible with CMOS.

CMOS (complementary metal-oxide-semiconductor structure; English CMOS, complementary metal-oxide-semiconductor) is a set of semiconductor technologies for building integrated circuits and the corresponding circuitry of microcircuits. The vast majority of modern digital circuits are CMOS.

The optical modulator is an important component in systems serving modern information and communication technologies. And not only in traditional data communication channels, but also in microwave photonics.

In contrast to previous work in this field, the scientists introduced a new modulator design concept in which photonics and electronics must be considered as a single integrated system in order to solve complex technical problems in this field.
