What were the first vehicles?

If you find yourself on a desert island and you need to drag something from one place to another, what are you going to do? drag! In ancient times, human muscles were the only means of transportation. Man himself was his own "pack animal". But over time, he tamed the animals, taught them to carry riders and loads.

Bulls, donkeys, buffaloes, horses, camels were used by ancient man in various parts of the world for transportation. This suited man for thousands of years, and then he wanted to find a way so that animals could carry more cargo.

Sledges and carts were invented to harness animals. Sledges and sledges with runners ran well in the snow, but were completely unsuitable on the ground.

Man invented the rolling cart. They consisted of pieces of logs instead of wheels placed under a cart or platform. When the cart was pulled, the logs rolled under it. This made the job easier than simply dragging the platform along the ground. She rolled over the logs, leaving them behind her. These logs were collected and placed again in front of the front end of the platform. And everything repeated again.

One day someone thought of cutting a log and making a hole in its center. This is how the wheel appeared - one of the greatest inventions of man. Then two wheels were connected with an axle, and the axle was attached to the platform. A rough cart appeared. Massive wooden wheels were heavy and clumsy, and they wore out quickly.

For thousands of years, man has perfected the wheel. By constructing it from separate hubs, bushings, rims and spokes, he was able to make it lighter and more efficient. Man made rims and tires out of copper or iron so that they could last longer. Finally learned how to make rubber tires.

Random interesting fact from the Great Encyclopedia:

How long can a chicken live without a head?

About two years.

On September 10, 1945, a plump young cockerel from Fruita, Colorado lost his head and survived. The ax miraculously did not hit the jugular vein, and enough of the brain stem was left on the neck so that the chicken not only lived, but also flourished.

Known as "Mike," the cockerel became a national hero, traveled nearly the entire country, and was even featured in magazines such as Time and Life. Its owner, Lloyd Olsen, charged twenty-five cents to see "Mike the Headless Wonder Chicken" at fairground shows across America. Mike appeared on stage with a dried chicken head - allegedly his own. In fact, the Olsen cat has long since finished with the original. At the height of his fame, Mike was earning $4500 a month and was valued at $10. His massive success sparked a wave of imitators, although none of the decapitated victims lasted more than two days.

They fed and watered Mike with a pipette. In the two years that have passed since the chicken lost his head, he gained almost three kilos and all the time he did nothing but happily “clean his feathers” and “peck” food with the remains of his neck. One person who knew Mike well commented: "He was a big, fat chicken who didn't know he didn't have a head."

But one day the unthinkable happened. The tragedy occurred in a motel room in Phoenix, Arizona. Mike choked, and Lloyd Olsen, to his horror, realized that he had left his pipette at the evening performance. Unable to clear his airway on his own, Mike suffocated to death.

Mike remains a cult figure in Colorado to this day. Since May 1999, the town of Fruita has celebrated his passing with a special Mike the Headless Chicken Day.

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 ... >>

hangover cure 17.04.2023

Chinese scientists have created cures for hangovers. They are based on beneficial bacteria that break down alcohol in the liver.

The researchers tested this remedy on mice. Before testing the probiotic, they recorded how long it took drunk mice to recover on their own, this parameter was 6-10 hours.

The study showed that mice given the probiotic regained exercise capacity after 5,5 hours. Mice not taking the probiotic took about 6,4 hours.

This drug not only reduced the amount of alcohol absorbed by the body, but also increased the length of time that the body tolerates alcohol, and also reduced the recovery time after acute alcohol poisoning.
