Who Invented Road Signs?

Did you know that traffic management has been a problem since long before the advent of automobiles. Julius Caesar was probably the first ruler in history to introduce traffic rules. For example, he passed a law according to which women had no right to drive chariots in Rome.

With the advent of automobiles, the first traffic controllers appeared who stood on the roads and showed the direction of movement with their hands. Then they were given signal lights. But they couldn't solve all the problems. Because the traffic flow changes throughout the day and there are very busy hours of traffic. Before 1920 there were no automatic traffic lights.

In 1927, two people patented the "automatic traffic controller". The first traffic lights were installed at the intersections to streamline traffic. One of the traffic lights, invented by Harry Howe of Yale University, was installed in New Haven, Connecticut in April 1928. This mechanism, which worked by means of pressure, indicated the movements on the roads. The car, approaching such a pointer, gave a signal to the signal box, and from there the command came to turn on the permission signal for the approaching car. This type of traffic light, but only now with the use of a light signal, exists today.

Charles Adler also invented the traffic controller in 1928, which used a microphone to signal a signal box. The driver, seeing the red light, blows the horn. The microphone transmits the sound to the signal box, from there a response signal is received to change the color of the traffic light. Nowadays, there are different types of road regulators that also respond to sound to switch traffic lights.

Which boy in the theater is often played by women?

Peter Pan in theatrical productions is often played not by boys, but by petite women. One of the reasons for this was that in England in the early 20th century, when James Barry wrote the work, there was a law prohibiting children under 14 from working after 21 pm.

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 ... >>

Siemens Gamesa wind turbine generates 359 MWh per day 16.10.2022

The prototype offshore wind turbine 14-222 DD, manufactured by the German-Spanish company Siemens Gamesa, one of the largest manufacturers of wind turbines, has set a world record for the output power obtained from a single turbine in 24 hours - 359 MWh. This would be enough for a medium-sized electric car to travel 1,8 million km.

The first electricity from the turbine was received recently, on the territory of a test center in Denmark. Rated at 14 MW and scalable up to 15 MW with Power Boost, this unit is designed for offshore installations.

By increasing the propeller diameter to 222 meters and using 108 meters of blades, the SG 14-222 DD increased its annual energy output by more than 25% compared to the previous model.

In addition, the turbine design has fewer moving parts, resulting in improved performance while maintaining reliability. And standardized production processes and a fully streamlined supply chain shorten the time to market for this model, which is scheduled for series production in 2024.

One such giant can provide enough energy to power 18 households a year.
