Don't be afraid, nothing threatens you. You can safely take a magnet in your hand and attach a needle to its end. She will stick, of course. Tear it off and attach it to the other end. It will also stick. Well, what if you attach it to the middle of the magnet? Look, it's falling! An amazing thing: the middle of the magnet is not "magnetic" at all. And the closer to the ends, the stronger the effect of the magnet. The ends of a magnet are called poles.

As I said, a magnet is not "contagious" for you. You can mess around with it as much as you like, you will not acquire any magnetic properties. Well, what about the needle? Did she get "infected"? Let's check. With the needle that touched the magnet, touch the other needles. You already know that you need to touch with the end: with a point or an eye. If magnetic properties are found anywhere, then it is there.

Well, isn't it attractive? Most likely not. And if it attracts, it is very weak. Maybe the “healthy” needle had, as doctors say, insufficient contact with the “sick”, that is, with the magnet? Nothing, we'll arrange contact now. Place the needle on the table and rub it hard with one of the poles of the magnet. Three only in one direction, say, from the point to the eye, and bring the magnet back through the air. Spend fifteen to twenty times.

Enough! Now the needle will probably "infect". Watch how she attracts her girlfriends!

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. ... >>

Biocompatible electrode cloth for clothing 15.02.2013

Japanese companies Nippon Telegraph and Telephone Corporation (NTT) announced the development of an electrode material that can be "sewn" into clothing fabric. A high-tech fabric is obtained by coating silk and synthetic fiber structures with a conductive PEDOT-PSS polymer.

The resulting material is highly flexible, not afraid of water and strong enough. According to the developers, such a fabric does not cause skin irritation and discomfort when touched directly and is biocompatible.

Unlike previous similar designs based on silver-plated fibers, the electrode tissue is characterized by a low noise level and can be used for applications such as continuous recording of an electrocardiogram. The novelty has already been tested on ten patients. After several days of continuous wearing of this fabric, people did not feel any discomfort. At the same time, the data were accurately measured.

In the future, developers plan to conduct more thorough testing of their product. In addition, the material can be used not only to obtain an electrocardiogram, but also in electroencephalography, remote patient monitoring, and telemedicine services.
