Determining distances from measured angles. Tourist tips

Tourist tips

Each object seen at an angle of 1° is removed at a distance 57 times greater than its size in diameter (more precisely, 57,3 times). A stick 1 m long at a distance of 57 m or 1 cm long at a distance of 57 cm is visible at an angle of 1°.

For angle measurements you can use the following rule.

Each object that is covered with the nail of the index finger (1 cm) is seen at an angle of 1° and is at a distance 57 times its diameter. If the nail covers half of the object, then its angular value is 2 °, and the distance is 28 diameters.

At an angle of 1 ', the distance is 3438 times the size of the object, 0,5 ° - 114 times, 5 ° - 11 times, 7 ° - 8 times.

The angular distance between the ends of the thumb and forefinger, as far apart as possible, corresponds to an angle of 15°. The width of the four fingers at the palm is 7°.

For example. A passenger car is visible in the distance, which is closed by about half the joint of the thumb, that is, it is visible at an angle of 2 °. The length of the car is known and equal to 24,5 m, therefore, it is at a distance of 24,5x28 = 686 m. If it is covered with the index finger, then the distance is equal to the size of the object multiplied by 30.

If an object is closed with a faceted pencil, then the distance to it is equal to the value of the object multiplied by 100.

Energy from space for Starship 08.05.2024

Producing solar energy in space is becoming more feasible with the advent of new technologies and the development of space programs. The head of the startup Virtus Solis shared his vision of using SpaceX's Starship to create orbital power plants capable of powering the Earth. Startup Virtus Solis has unveiled an ambitious project to create orbital power plants using SpaceX's Starship. This idea could significantly change the field of solar energy production, making it more accessible and cheaper. The core of the startup's plan is to reduce the cost of launching satellites into space using Starship. This technological breakthrough is expected to make solar energy production in space more competitive with traditional energy sources. Virtual Solis plans to build large photovoltaic panels in orbit, using Starship to deliver the necessary equipment. However, one of the key challenges ... >>

New method for creating powerful batteries 08.05.2024

With the development of technology and the expanding use of electronics, the issue of creating efficient and safe energy sources is becoming increasingly urgent. Researchers at the University of Queensland have unveiled a new approach to creating high-power zinc-based batteries that could change the landscape of the energy industry. One of the main problems with traditional water-based rechargeable batteries was their low voltage, which limited their use in modern devices. But thanks to a new method developed by scientists, this drawback has been successfully overcome. As part of their research, scientists turned to a special organic compound - catechol. It turned out to be an important component that can improve battery stability and increase its efficiency. This approach has led to a significant increase in the voltage of zinc-ion batteries, making them more competitive. According to scientists, such batteries have several advantages. They have b ... >>

Alcohol content of warm beer 07.05.2024

Beer, as one of the most common alcoholic drinks, has its own unique taste, which can change depending on the temperature of consumption. A new study by an international team of scientists has found that beer temperature has a significant impact on the perception of alcoholic taste. The study, led by materials scientist Lei Jiang, found that at different temperatures, ethanol and water molecules form different types of clusters, which affects the perception of alcoholic taste. At low temperatures, more pyramid-like clusters form, which reduces the pungency of the "ethanol" taste and makes the drink taste less alcoholic. On the contrary, as the temperature increases, the clusters become more chain-like, resulting in a more pronounced alcoholic taste. This explains why the taste of some alcoholic drinks, such as baijiu, can change depending on temperature. The data obtained opens up new prospects for beverage manufacturers, ... >>

Found a mechanism that turns off the feeling of hunger 05.06.2021

New research by scientists may help control obesity in the future. It turned out that there is a neural mechanism in the brain that regulates the feeling of fullness when eating. If you influence it, then you can reduce or increase the feeling of hunger. So far, the experiment has been carried out only on animals.

The neural mechanism was discovered by scientists at the Baylor College of Medicine in the United States, who used it to force laboratory mice to eat more and less than usual.

The mechanism consists of two groups of neurons. The first - DA-VTA - produces dopamine, the second - DRD1-LPBN - regulates food intake. The scientists found that the activity of the first group increased just before the mice stopped eating. After the production of dopamine occurs, the neurons from the second group turn on. They cause a desire to refuse food. When the researchers suppressed these neurons, the animals began to overeat. Artificial stimulation, on the contrary, discouraged mice from the desire to eat, according to the official website of Baylor College of Medicine.

The researchers suggest that in humans, hunger and satiety are regulated in the same way as in mice. Such "low-level" neural mechanisms are usually the same in humans and many other animals. There is a possibility that in the future there may be drugs that will regulate people's desire to eat.
