Who Invented Skates?

Man has been skating for over 500 years! Ice skating is much older than roller skating, as roller skating was only introduced in the eighteenth century. Roller skates were used on the roads in Holland about 200 years ago, and we don't know who actually made them and stood on them. A New Yorker named J. L. Plimpton invented the four-wheel roller skate in 1863. They were skated on a rubber mat, it was this type of skate that made roller skating popular.

The next step in the development of inline skates was ball bearing skates. The wheels for the first inline skates were made of boxwood, but the edges of the wooden wheels broke off too easily. Soon the wheels were made of hard alloys or steel.

Until about 1910, roller skating was very popular in America, and then they were supplanted by motorcycle racing and sports car racing. But there is no doubt that roller skating has remained one of the favorite sports of young people.

Ice skating began around the XNUMXth century. In those days, Scandinavians tied skates made from animal bones to their feet and glided on ice surfaces. Then came metal skates, from which modern steel skates are descended.

Once upon a time, skates were attached to the legs with long leather straps. Later, skates began to be attached to shoes with clips and straps. Currently, skates are rigidly attached to boots.

Watching what movie inspired physicists to new scientific publications about black holes?

Physicist Kip Thorne was the scientific adviser to the writers of Interstellar. To realistically visualize a spinning supermassive black hole and the gravitational lens it forms, Thorne wrote many pages of theory. The resulting rendering, in turn, inspired Thorne with new ideas about gravitational lenses and accretion disks, leading him and his colleagues to publish three new scientific papers.

Machine for thinning flowers in gardens 02.05.2024

In modern agriculture, technological progress is developing aimed at increasing the efficiency of plant care processes. The innovative Florix flower thinning machine was presented in Italy, designed to optimize the harvesting stage. This tool is equipped with mobile arms, allowing it to be easily adapted to the needs of the garden. The operator can adjust the speed of the thin wires by controlling them from the tractor cab using a joystick. This approach significantly increases the efficiency of the flower thinning process, providing the possibility of individual adjustment to the specific conditions of the garden, as well as the variety and type of fruit grown in it. After testing the Florix machine for two years on various types of fruit, the results were very encouraging. Farmers such as Filiberto Montanari, who has used a Florix machine for several years, have reported a significant reduction in the time and labor required to thin flowers. ... >>

Advanced Infrared Microscope 02.05.2024

Microscopes play an important role in scientific research, allowing scientists to delve into structures and processes invisible to the eye. However, various microscopy methods have their limitations, and among them was the limitation of resolution when using the infrared range. But the latest achievements of Japanese researchers from the University of Tokyo open up new prospects for studying the microworld. Scientists from the University of Tokyo have unveiled a new microscope that will revolutionize the capabilities of infrared microscopy. This advanced instrument allows you to see the internal structures of living bacteria with amazing clarity on the nanometer scale. Typically, mid-infrared microscopes are limited by low resolution, but the latest development from Japanese researchers overcomes these limitations. According to scientists, the developed microscope allows creating images with a resolution of up to 120 nanometers, which is 30 times higher than the resolution of traditional microscopes. ... >>

Air trap for insects 01.05.2024

Agriculture is one of the key sectors of the economy, and pest control is an integral part of this process. A team of scientists from the Indian Council of Agricultural Research-Central Potato Research Institute (ICAR-CPRI), Shimla, has come up with an innovative solution to this problem - a wind-powered insect air trap. This device addresses the shortcomings of traditional pest control methods by providing real-time insect population data. The trap is powered entirely by wind energy, making it an environmentally friendly solution that requires no power. Its unique design allows monitoring of both harmful and beneficial insects, providing a complete overview of the population in any agricultural area. “By assessing target pests at the right time, we can take necessary measures to control both pests and diseases,” says Kapil ... >>

Sports that extend life 04.12.2016

An international team of researchers led by Emmanuel Stamatakis, Associate Professor at the University of Sydney, has analyzed a large body of medical data to find out which sports do and do not extend life.

Scientists used data from 80,3 thousand people over 30 from England and Scotland. The analysis showed that the risk of death for people who regularly played various types of tennis was lower by as much as 47%. For swimmers, this figure was 28%, for aerobics it was 27%, and for cyclists it was 15%.

At the same time, the chances of dying specifically from cardiovascular disease in tennis players were lower by 56%, in swimmers - by 41%, and in people involved in aerobics - by 36%.

There was no association between football/rugby and running/walking activities and time of death.
