What astronomical discovery of the XNUMXth century was classified?

In the summer of 1967, a graduate student of the famous English radio astronomer Anthony Hewish, Miss Bell, unexpectedly discovered a completely unusual radio source in the sky. It emitted short-term pulses, which were strictly periodically (every 1,33 seconds) repeated. Three more such sources with similar, almost second periods were soon discovered.

Suspecting that these signals are of artificial origin, the researchers classified their observations. For almost half a year, no one knew about them - an unprecedented case in the history of modern astronomy. Only after the scientists were convinced of the natural nature of the sources of radio pulses, the results of the observations were published.

The mysterious source of radio emission turned out to be a pulsar - a rapidly rotating and highly magnetized neutron star. By the end of 2000, more than a thousand pulsars had already been discovered, their periods ranging from thousandths of a second to several seconds.

The electromagnetic radiation of a pulsar is created by the rotational energy of a neutron star. The loss of energy leads to a slowdown in the rotation of the star, so the older the pulsar, the longer the period of its pulsation.

Where did the game of golf come from?

This game first appeared in medieval Denmark. One of the first and still one of the most famous golf courses is St. Andrew. At first, 9 holes were arranged there, into which it was necessary to send the ball. Currently, all golf courses have 18 holes.

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. ... >>

New bonding material for batteries 15.03.2021

The Japan Advanced Institute of Science and Technology presents the results of a new study that promises a breakthrough in battery development. A new binder material developed by the Japanese shows a more efficient charge retention. Compared to the current performance of lithium-ion batteries, future battery systems can power electric vehicles and smartphones at a higher level.

There are many moving parts inside a battery. Each of these contributes to a decrease in performance. And now, the work carried out by scientists at the Japan Advanced Institute of Science and Technology is focused on such an important component of the battery structure as a binder material between the electrodes and electrolyte.

The bonding material plays an important role in protecting the battery's graphite anode, one of the two system electrodes. The binder material holds the particles together and keeps them in contact with the current collector. The current lithium battery binder is made from polyvinylidene fluoride (PVDF). So, Japanese experts have found a much better alternative.

The new Japanese-made product was named: bis-imino-acenaphthenquinone-paraphenylene. A Japanese bonding material has been tested as part of an experimental half-cell battery with an anode protection that provides connection to the current collector. At the same time, a number of significant performance improvements were noted. First of all, due to the ability of the binder material to maintain capacity for multiple charge cycles.

There is improved mechanical stability, reliable adhesion to the anode and current collector. The new bis-imino-acenaphthenquinone-paraphenylene binder also showed better conductivity under finer structure conditions compared to the PVDF used today.

In a completely different way, the new binder material reacts with the electrolyte, which helps to increase the service life of the batteries. Microscopic scanning showed the appearance of small cracks no earlier than after 1700 cycles. Again, comparing with PVDF, Japanese scientists noted the appearance of large cracks in the PVDF structure after 500 cycles.
