Do planets affect weather and climate?

They influence, and some scientists believe that they influence very significantly. According to the theory of the Bashkir scientist R. Shagiev, weather and climatic conditions approximately repeat themselves after 24 years and depend on the position of the so-called barycenter - the common center of mass of all objects in the solar system. The circulation of air masses in both hemispheres of the Earth depends on its location.

According to the theory of R. Shagiev, in the Northern Hemisphere the years 2009 and 2013 will be dry, with low yields. Winters of 2007-2008, 2012-2013 are expected to be cold, and winters of 2009-2010, 2010-2011, 2011-2012 are expected to be snowy and warm.

Who Invented the Bicycle?

If we try to trace the origin of the bicycle, we will probably have to go back thousands of years to the land of Ancient Egypt. There is evidence that the Egyptians already had some kind of two-wheeled mechanism that was set in motion by the rider's feet. But the appearance of the first models of bicycles for wide practical use can be dated back to 1817. It was then in Germany that Baron von Dresz presented to the public a mechanism that he called the "trolley" in his honor. The two wheels of the trolley were connected by a wooden bar. The rider transferred part of the body weight to a wooden stop in front of him and moved the trolley forward, pushing off the ground alternately with his left and right legs. He controlled the trolley by turning the handle mounted on the axle of the front wheel.

This mechanism was nicknamed "dandy horse" (first-class horse) for its high price. By the way, the English king George IV loved to ride on it!

Around 1840, the Scotsman Macmillan took an old "dandy horse" and put levers on the axle of the rear wheel. They were connected by drive rods to the pedals. He drove it so fast that he was even arrested for "driving crazy"!

The name "bicycle" ("bicycle") first appeared in 1865, when the Frenchman Lalemin attached levers and pedals to the front wheel of a mechanism very similar to the "dandy horse". These bikes were jokingly nicknamed "clunkers" because they had heavy wooden frames and iron rims that shook when ridden. In 1868, light metal wheels with wire spokes and massive rubber tires came into use. All of these bikes had the same wheel size.

Shortly thereafter, a new type of bicycle appeared - with a large front wheel. As it improved, the front wheel got bigger and bigger. As a result, one revolution of the pedals attached to the axle propelled the bike a greater distance. In some models, the front wheel reached a diameter of 1,5 meters or even more, while the rear wheel was only 30 centimeters. The rider was located above the huge front wheel, and if he lacked the dexterity to stay in the saddle, the walk could end with a fall head first!

And finally, around 1885, the modern "safe bicycle" appeared. In this model, the wheels were the same size, and the seat was located slightly forward of the rear wheel. The sprocket on the pedals was made much larger than on the rear wheel, and so with each turn of the pedals, the rear wheel covered the same distance as the unsafe large front wheel in previous models.

Subsequent improvements finally gave the bike a modern look.

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 ... >>

The tire pumps energy 28.11.2008

Belgian microelectronics engineers have created a cheap energy collector that can power a small sensor.

An energy collector is a device that converts waste mechanical energy into electrical energy. For example, a tire is rolling down the road. At the same time, it inevitably deforms. The deformation of the rubber could, in principle, be turned into electricity and powered by a sensor that would monitor the grip of the tire on the road and report this to the on-board computer. And he is already taking measures to prevent an accident.

In practice, to obtain such electricity, a miniature device like a cantilever with a weight is used. When the tire moves, the weight deflects up and down, deformation occurs at the base of the cantilever. If a piezoelectric is located there, it will turn the deformation into electricity. There is nothing surprising in such a device, and today it is only a matter of making the collector cheaper and more efficient.

Scientists from the Interuniversity Microelectronic Center located in Levin, Belgium, proposed taking aluminum nitride as a piezoelectric. It is applied to a platinum electrode, and covered with aluminum on top. Such collectors are easy to make in mass quantities using conventional microchip manufacturing technology, while its parameters are record-breaking: the output voltage is 60 μV, and the optimal oscillation frequency is only 500 times per second.
