What is the size and age of the largest meteorite crater on the Earth's surface?

The largest of all the craters in which the remains of a meteorite substance were found is the Barringer crater in Arizona (USA).

It is a well-preserved depression with a diameter of about 1200 meters and a depth of about 200 meters. Its edges rise about 50 meters above the surrounding plain. It was discovered in 1891, and according to various estimates, its age is from 25 to 50 thousand years.

The meteorite, the fall of which led to the formation of this crater, weighed about 10 thousand tons.

How can ice flow?

Ice is subject to fluidity - the ability to deform under stress determines the movement of ice in huge glaciers. Some Himalayan glaciers move at a speed of 2-3 meters per day.

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. ... >>

Magnetic monopoles in a cold quantum gas medium 23.07.2018

It is known that magnets shaped like a ball, rectangle or horseshoe always have two magnetic poles. And if you split the magnet into two parts, you get two new magnets with two poles. However, according to some physical theories, unipolar magnetic formations can exist in the world, similar to electric charges, which are either positive or negative. One of these magnetic formations, the Young's monopole, may exist from the point of view of high-energy physics, but none of the scientists has yet had a chance to "see" this monopole live, even in laboratory conditions.

A group of physicists from the Joint Quantum Institute (JQI) succeeded for the first time in creating an analogue of the Yang monopole based on a quantum gas from supercooled rubidium atoms. And this achievement can be used in the future for a deeper insight into already known areas of physics and new areas that have not yet been covered by human science.

In order to detect the Yang monopoles that exist in a quantum gas, scientists, using radio waves and microwave rays, aligned all the spins of quantum gas atoms in a special way. Periodically repeating combinations of four different orientations of rotation of atoms, the researchers made these atoms move in space-time, while each atom returned to the starting point after a while.

As each atom completed its full circle, the scientists measured its spin and compared it to its original spin. It was found that the spin of the atom did not correspond to the original, and small differences, according to the assumptions, could arise due to the fact that the atoms moved in a curved space-time continuum. Having calculated the parameters of the curvature of the continuum, the scientists determined that they exactly correspond to the curvature created, from the point of view of the theory, by the Young monopole.

In order to test that the curvature of the continuum is indeed caused by the presence of a Yang monopole, the researchers made the atoms move in different ways, even those that should go around the area of \uXNUMXb\uXNUMXbthe curvature and distortion created. The atoms moving along this path, returning to the starting point, had the same spin as at the very beginning, which indicated that they managed to avoid the influence of the monopole.

Using the approach described above and directing the atoms in different ways, the researchers determined that the Yang monopole is a topological phenomenon, i.e. it has a certain size and shape. And in their further research, scientists will find out how it will be possible to make Yang's monopoles work for the benefit of mankind in a wide variety of quantum technologies.
