Where did the train crash happen due to the language barrier?

In 2001, there was a railway accident in Belgium in which 8 people, including both drivers, died as a result of a head-on collision of trains.

Among other accidents, this one is unique in that its main cause was the language barrier. When the driver of the first train left the station despite the red traffic light, the dispatcher called the next station to warn about it. However, the controllers did not understand each other, as one spoke French and the other Dutch.

Both of these languages are official in Belgium, and according to the rules of the railway company, staff must know at least one of them.

Random interesting fact from the Great Encyclopedia:

How does an airplane take off?

To understand how an airplane rises into the air, we first need to understand the forces that keep airplanes in the air. Since an airplane weighs more than the same volume of air, it needs a force to keep it in the air. It's called lifting power. The aircraft develops this force by rapidly moving forward and overcoming air resistance.

Why does this movement create lift? Due to the fact that in the process of its air masses flow around the wings. The air dissected by an airplane passes over and under the wings. That part of it that passes under the wings pushes the plane up. The wing has a convex shape on the upper side, and the air, bending around this bulge, creates a zone of low pressure at these points.

Thus, there are two forces acting simultaneously: the air under the wings pushes the aircraft up, and the reduced pressure above the wings contributes to this movement. The result is an uplift. To move forward, the aircraft needs the power of the engine. Propellers are screwed into the air just like a screw into wood. This effect becomes possible due to the fact that the air, when moving quickly through it, as well as when the air itself moves quickly, begins to act as a dense medium. This forward movement is called thrust. Thrust overcomes air resistance, lift overcomes the force of gravity - and the plane flies through the air. As long as the lift force balances the gravitational forces, the plane moves straight ahead at the same level.

As the speed increases, the aircraft will shoot up as the lift force has increased and the pilot needs to lower the nose of the aircraft slightly to counteract this force. If the speed decreases, the pilot must raise the nose of the aircraft slightly up. If this is not done, the air flow around the wings is stalled, the aircraft loses lift and, accordingly, speed, risking entering a tailspin.

If the stall occurs high in the sky, this height is enough to level the plane and pick up speed again, but if it happens low above the ground, disaster is inevitable.

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 ... >>

Chocolate improves eyesight 02.05.2018

Experts from Incarnate Ward University conducted a study on the effect of chocolate on human vision.

Scientists gave the participants of the experiment about 42 grams of chocolate - dark, with a share of cocoa in 72%, or milk. Then their eyesight was tested, and those who ate dark chocolate had slightly sharper eyesight and better contrast. True, the effect was very small - the researchers themselves admit that in everyday life there is unlikely to be any benefit from such an improvement in vision, and the chocolate only worked for a couple of hours.

As for the mechanism, it’s probably all about the famous flavonoids again, which are quite abundant in cocoa beans: it can be assumed that flavonoids improve the blood supply to the retina, thereby increasing visual acuity.
