Random interesting fact from the Great Encyclopedia:

What was the color of the sky in ancient Greece?

Bronze. There is no word for "blue" in ancient Greek.

The closest words, glaukos and kyanos, are more an expression of the relative intensity of light and dark than an attempt to describe color.

The famous ancient Greek poet Homer in the poems "Iliad" and "Odyssey" mentions only four actual colors, roughly translated as black, white, greenish-yellow (in relation to honey, vital juices and blood) and purple-red.

When Homer calls the sky "bronze", he is referring to its dazzling brightness (like the gleam of a shield) rather than its "bronze color". In a similar spirit, the poet regards wine, the sea and sheep: they are all described in one color - "purple-red".

Aristotle singled out seven color shades, and all of them, in his opinion, came from black and white, but these latter, in his understanding, are not degrees of color, but brightness.

It is interesting that both the ancient Greek, who lived 2500 years ago, and the modern "rovers" of NASA approach the issue of color in almost the same way.

In Darwin's era, a theory was put forward that the ancient Greeks' retinas were not sufficiently developed to perceive colors. However, today it is believed that the ancient Greeks grouped objects based not on color, but on qualities, so that the word that was supposed to mean "yellow" or "light green" actually meant "liquid", "fresh" and "live" - and, accordingly, was used to describe the blood, the life juice of a person.

In fact, all this is not such a rare occurrence as one might expect. There are more languages on the islands of Papua New Guinea than anywhere else, but in many of them, apart from the distinction between light and dark, there are no other words for color.

In the classical Welsh (Welsh) language, there were no words that convey colors such as brown, gray, blue and green. The color spectrum was divided quite differently. One word (glas) covered part of the green, another the rest of the green, all blue, blue and some of the gray, and the third dealt with the remains of the gray and more or less of the brown.

Modern Welsh uses the word glas in the meaning of English blue, but in Russian there is no single word equivalent to English blue. The Russian language uses two words - blue and blue - which are usually translated into English as light blue and dark blue, while for the Russians themselves these are two completely separate, different colors, and not different shades of the same.

In all languages, color terminology develops in the same way. The third, after black and white, is usually called red, the fourth and the fifth are green and yellow (in one order or another), the sixth - blue (blue) and the seventh - brown. In modern Welsh, by the way, there is no word for brown.

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 ... >>

Microbial fuel cells 09.12.2012

An unexpected source of new, environmentally friendly energy has been found - a microbial fuel cell plant that can generate electricity from the natural interaction between living plant roots and soil bacteria, that is, extract electricity from the most ordinary swamps. This technique is already being used, but so far on a small scale. And soon it will be used everywhere in large wetlands around the world.

The microbial fuel cell plant draws electricity from the soil while the plants continue to grow. Plants produce organic matter through photosynthesis. The roots release up to 70% of this material into the soil. And all this remains unused and literally disappears into the ground. Bacteria around the roots decompose organic residues, thus forming a new source of electricity. Degradation processes release electrons. Researcher Marjolein Helder and her colleagues placed electrodes among bacteria to absorb these electrons and thereby generate electricity using potential differences.

A microbial fuel cell plant can currently generate 0,4 watts per square meter of swamp turf. This is more than what is created by the fermentation of biomass. In the future, bioelectricity from a plant will be able to produce 3,2 watts per square meter of green mass. This means that a 100 m2 plot, placed on a flat roof, will generate enough electricity to power household appliances in the house at an average consumption of 2800 kWh per year. Various types of plants can be used, including herbs as common as English cordgrass, and in warmer countries, rice.
