What is the largest tree?

The giant sequoiadendron, or mammoth tree (Sequoiadendron giganteum), is considered the largest tree. It grows in California along the western slopes of the Sierra Nevada at an altitude of 1500-2500 meters, has a straight slender trunk and a dense conical or rounded crown.

The height of the tree can reach 100 meters, the diameter of the trunk is 10 meters.

The largest specimen of the currently existing has a height of 83 meters and a trunk circumference of 24,11 meters.

Random interesting fact from the Great Encyclopedia:

What should not be drunk when dehydrated?

Alcohol is possible. Just like tea and coffee.

Basically, any liquid will help you stay hydrated, although you should stay away from sea water.

It is not clear where this strange idea came from, that any liquid other than water leads to dehydration. There is no scientific basis for such a statement. As a diuretic (i.e. a diuretic), caffeine does cause water loss - however, only a small fraction of what you add to the body when drinking a cup of coffee. In terms of fluid replacement in children, everything is equally good - be it tea, coffee, milk or lemonade.

Ron Moan, professor of human physiology at the University of Aberdeen Medical College, while studying the effects of alcohol (also, by the way, considered a diuretic) on the human body, found that in moderate doses, alcohol practically does not affect the fluid balance of the average person.

The results of his research, published in the Journal of Applied Physiology, show that alcoholic beverages with an alcohol content of less than 4% (for example, light or light beer) can be safely consumed to prevent dehydration. Sea water, on the other hand, is an emetic, so you will certainly turn inside out if you decide to fight dehydration with it. But if you still manage to overpower yourself and swallow even a little, all the moisture contained in the cells of your body, following the law of osmosis, will rush to this highly concentrated salty liquid in order to dilute it.

As a result, your cells will lose water, and in severe cases, this can even lead to spasms, impaired brain activity, as well as liver and kidney failure.

The existence of an entropy rule for quantum entanglement has been proven 09.05.2024

Quantum mechanics continues to amaze us with its mysterious phenomena and unexpected discoveries. Recently, Bartosz Regula from the RIKEN Center for Quantum Computing and Ludovico Lamy from the University of Amsterdam presented a new discovery that concerns quantum entanglement and its relation to entropy. Quantum entanglement plays an important role in modern quantum information science and technology. However, the complexity of its structure makes understanding and managing it challenging. Regulus and Lamy's discovery shows that quantum entanglement follows an entropy rule similar to that for classical systems. This discovery opens new perspectives in the field of quantum information science and technology, deepening our understanding of quantum entanglement and its connection to thermodynamics. The results of the study indicate the possibility of reversibility of entanglement transformations, which could greatly simplify their use in various quantum technologies. Opening a new rule ... >>

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 ... >>

Ultrasonic lenses 01.11.2004

This seems to be a trick of a magician: a disk of transparent material, enclosed in a metal frame, suddenly, while maintaining the plane-parallel sides, turns into a collecting or diverging lens.

The secret of flat lenses developed in one of the laboratories of Triton Systems (USA) lies in ultrasound. Piezoelectric ultrasound emitters are enclosed in a frame around a transparent silicon rubber disc. Passing through the rubber, ultrasound waves either slightly push the molecules apart, or compress them, making the material either more rarefied or denser. Dense areas refract light more.

The frequency and phase of the emitters in the frame on the sides of the disk can be chosen such that due to the interference of waves in the center of the disk, a stable region with a reduced density is formed, and hence with a reduced refractive index of light. A flat transparent disk turns into a diverging lens.

So far, the successes of researchers are small - only the central zone with a diameter of several millimeters changes its optical properties. But in the future, heavy and long lenses with a variable focal length can be replaced by a flat transparent plate controlled by electronics.
