What makes football fields look striped?

To make a football field striped, you do not need to sow grass of different varieties. Stripes occur because the grass is cut in different directions by lawn mowers, which not only cut it, but also crush it. If the grass is tilted away from the viewer, that area of the lawn appears lighter due to the higher reflection area from the whole stems, and vice versa. Stripes are needed not only for beauty - they help side judges in determining offsides.

Random interesting fact from the Great Encyclopedia:

When did people start cutting their hair?

Hair appeared as a result of the development of the stratum corneum of the skin. We don't get hurt when we cut our hair because it doesn't contain nerve endings. Since hair is an important part of our appearance and is very easy to cut and style, people have been doing it since time immemorial.

No one can answer who first thought to cut and style hair. But thousands of years ago, primitive women already used combs! Men and women have also curled their hair since time immemorial.

But relatively recently, a tradition has arisen according to which men cut their hair short, and women leave it long. In the Middle Ages, men wore long hairstyles, curled their hair and even woven ribbons into it! If the hair was not long enough, the men would wear hair wigs that they bought from commoners.

Henry VIII, King of England, first introduced short haircuts for men. He ordered all men to cut their hair, but allowed them to grow beards and curl mustaches. When James I became king, long hair and wigs came back into fashion.

In the middle of the XNUMXth century, the male population of England split into two camps: those who wore long hair and short beards, and those who cut their hair short and grew beards. Over the next hundred years, fashion was constantly changing, and finally, at the beginning of the XNUMXth century, the custom was finally established, forcing men to cut their hair short.

Women have always sought to grow their hair, but at the court of Louis XIV it was fashionable to curl it. Today, women cut their hair short, not only because it is fashionable, but also because then it is easier to take care of their hair: you don’t have to constantly use hairpins, comb and curl them for a long time.

Hairdressers and hairdressers also appeared relatively recently. In England they were recognized only in 1461, and in France - during the time of Louis XIV.

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 ... >>

First NXP RF Transistor 30.11.2007

NXP Semiconductors has introduced the first of a series of discrete silicon solutions, the BFU725F high-frequency NPN transistor.

The BFU725F transistor has impressive performance: high switching frequency (70 GHz), high gain (27 dB at 1,8 GHz/10 dB at 18 GHz) and very low noise (0,43 dB at 1,8 GHz/0,7, 5,8 dB at XNUMX GHz). This makes it ideal for a variety of RF applications.

The ultra-low noise improves reception of sensitive RF receivers such as GPS, DECT phones, satellite radios, WLAN/CDMA devices, while the high cut-off frequency is ideal for applications operating in the 10 to 30 GHz range, such as blocks of satellite systems.
