In the mirror, you see yourself differently from how others see you. In fact, if you comb your hair to one side, in the mirror it will be combed to the other. There are moles on the face, they will also be on the wrong side. If all this is turned in a mirror, the face will seem different, unfamiliar.

How can you see yourself the way others see you? The mirror turns everything upside down... Well then! Let's outsmart him. Let's slip him an image, already inverted, already mirrored. Let it turn over again on the contrary, and everything will fall into place!

How to do it? Yes, with the help of a second mirror! Stand in front of the wall mirror and take another one, manual. Hold it at an acute angle to the wall. You will outsmart both mirrors: your "right" image will appear in both. This is easy to check with the font. Bring a book with a large inscription on the cover to your face. In both mirrors, the inscription will be read correctly, from left to right!

Outsmart the Mirror

Now try to pull yourself by the forelock. I'm sure it won't work right away. The image in the mirror this time is perfectly correct, not turned right to left. That is why you will be wrong. You're used to seeing a mirror image in a mirror!

In shops of ready-made dresses and in tailoring studios there are three-fold mirrors, the so-called trellises. In them, too, you can see yourself "from the outside."

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.

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. ... >>

Hewlett Packard e-book 27.09.2003

Hewlett Packard announced the creation of a prototype device, which, in fact, is an e-book.

The device is no larger than a standard book and about 1 cm thick has a liquid crystal screen, along the perimeter of which there are touch panels. The device is connected to a regular personal computer via a USB port. After a short search and "download" procedure, the user is able to read the downloaded literature.

The process of turning pages is as close as possible to the original: the reader simply swipes his finger on one of the touch panels, and the page visually "turns over". You can also select text fragments and enlarge them. Reading newspapers is carried out in a similar way.

The main drawback of the device developers consider the screen of the e-book. Firstly, it, like any monitor, causes eye fatigue, and secondly, its dimensions are not very large yet. However, the rapid development of technology in the near future should solve both of these problems.
