How did a motorcyclist protesting the use of helmets reluctantly prove himself wrong?

In 2011, bikers demonstrated in the state of New York to protest against the law on the mandatory use of helmets when riding motorcycles. One of the participants, named Philip Kontos, lost control, hit his head on the asphalt and died. Doctors and police stated that he would have survived while wearing a helmet.

How did the concept of Uncle Sam come about?

"Uncle Sam" is sometimes referred to as the United States. It is hard to believe that this name appeared by chance and that there really was such a person who was called "Uncle Sam". Most people have never heard of him. But there was a man by the name of Wilson, who really was called "Uncle Sam." He was born in Arlington, Massachusetts on September 13, 1766. His father and older brothers took part in the American Revolution.

Sam was drafted at the age of 14 and served until the end of the war. After the war, he went to Troy, New York, and went into the canned meat business. On October 2, 1812, a group of sightseers came to the plant. One of them, New York Gov. Daniel D. Tompkins, asked what the letters "EAUS" on jars of meat stand for. The worker replied that "EA" means the partner who is supplied with Wilson's canned food - Elbert Anderson. And then he jokingly added that the letters "US" (in English, these are the first letters of the name of the United States) mean "Uncle Sam" (the initial letters of these words in English are written in exactly the same way - US).

This case was reported on May 12, 1830 by the New York Gazette and General Advertiser. And since Wilson was known as a hardworking and patriotic person, the image of "Uncle Sam" very quickly established itself as a symbol of a person of this type. By the end of the War of 1812, "Uncle Sam" had come to symbolize the character of the entire nation, the American state and government. In 1961, Congress passed a resolution declaring "Uncle Sam" Wilson of Troy, New York, to be the progenitor of the American national symbol. Americans today are proud of the image of "Uncle Sam". But surprisingly, few people remember the person who invented it.

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 ... >>

New automation in Nissan cars 19.07.2014

Japanese automaker Nissan promises to bring to the mass market several systems that can take control of the car at a certain point in time. In addition to automatic driving at intersections, Nissan cars will be able to park themselves, navigate through traffic jams and maneuver on a multi-lane road.

Renault-Nissan Alliance President and CEO Carlos Ghosn, speaking at a press conference at the Foreign Journalists' Club in Japan, said that by the end of 2016 many Nissan models will have autopilot for driving on busy city roads. By the same time, the manufacturer will release a fully automatic parking system.

The top manager did not specify the capabilities of the parking assistant. It is possible that the electronic assistant will independently find a parking space, park the car, and then return it to the owner. This functionality has previously been demonstrated by Volvo.

In 2018, Nissan promises to introduce a system of simultaneous control of multiple lanes. With its help, the car, recognizing other road users and various obstacles on the road, will be able to choose the safest lane for driving. Also, by the end of the current decade, cars of the Japanese brand will be able to drive through intersections without the participation of a driver.
