Where did cabbage come from?

Cabbage is a very ancient plant, and from it came many other edible plants, among which there are those that you will never guess that they have something to do with cabbage! Many thousands of years ago, cabbage was a useless plant that grew along the sea coast of Europe. It had bright yellow flowers and shriveled leaves. More than one hundred and fifty varieties of cultivated plants originated from this wild ancestor.

The best known are common cabbage, fodder cabbage, Brussels sprouts, cauliflower, broccoli and kohlrabi. Ordinary cabbage has a central shoot, around which grow, closely pressed against each other, leaves that form a large hard head. Red and white cabbages have smooth leaves. Fresh white cabbage can be eaten raw or boiled.

Forage cabbage resembles wild cabbage, as its leaves grow to large sizes and grow separately from each other. Brussels sprouts resemble both white and fodder at the same time. Small heads, resembling the forks of large white cabbages, grow on the stem at the base of the leaves, which are large and fully unfolded.

In cauliflower, they do not eat leaves, but flower buds, which have a delicate aroma. These buds grow into a hard mass surrounded by a few free-growing leaves. Because cauliflower is very difficult to grow, the Italians developed a more forgiving variety called broccoli. Kohlrabi has round bulges on the stem right next to the ground, and it is these bulges that are eaten when they are still young and tender.

Random interesting fact from the Great Encyclopedia:

What is chlorine?

Pure chlorine is a gas. This is one of the most poisonous gases, but at the same time - and one of the most useful! In nature, chlorine is part of various compounds - for example, ordinary table salt (sodium chloride).

Pure chlorine was first obtained in 1774 by the Swedish chemist Carl Scheele. Currently, it is obtained cheaply by passing an electric current through a solution of common salt.

Poison gas, first used in World War I, consisted almost entirely of pure chlorine. German troops used it on 22 April 1915. Both sides used various poison gases consisting of chlorine compounds. In World War II, despite the fact that both warring parties had large stocks of poison gases, they did not use it in hostilities.

At the same time, despite the fact that chlorine is poisonous and dangerous, it is one of the most reliable means of combating human health. As part of many herbicides and disinfectants, chlorine destroys microbes. In many cities, water treatment systems use chlorine to kill bacteria. At the same time, four to five parts of chlorine are used per million parts of water. This amount is harmless to humans, but sometimes the water tastes like chlorine.

Chlorine can be liquefied by refrigeration and high pressure. Liquid chlorine is transported in metal containers or special tanks.

Chlorine is used in bleaching and in the manufacture of bleaching powders. Chlorine is especially widely used in paper bleaching. It is also used in dyes, and compounds with oxygen and potassium - in the creation of fireworks, as well as in the manufacture of matches.

Explosion-proof cleaner carbon tetrachloride is also a chlorine compound. It is also used in some types of fire extinguishers. Chlorine is also an integral part of modern antiseptics.

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 ... >>

48-layer 3D NAND flash 25.03.2015

Toshiba announced in an official press release that it has begun shipping pilot batches of the industry's first 48-layer 3D NAND flash memory.

The chip capacity is 128 Gbit (16 GB). Each memory cell stores two bits of data. By the way, Toshiba has its own designation for this type of memory - BiCS (Bit Cost Scalable) - scaling the cost of storing one bit. The company will begin mass production of BiCS memory in the first half of 2016. In principle, this is consistent with the company's past plans to launch 3D NAND-flash during fiscal 2015 (calendar - until April 2016).

Mass production of BiCS memory will be handled primarily by the company's now rebuilt Fab 2 factory in Yokkaichi. Let us remind you that Samsung has been producing 128 Gbit 3D NAND memory in mass quantities for a year and a half already and has reached the production of the second generation of such memory (both in the form of MLC and TLC NAND).

Intel and Micron will begin mass production of 3D NAND in the second half of this year and immediately begin production with 256-Gb chips. Samples of such memory are already supplied.

It can be concluded that 3D NAND memory will appear in significant volumes closer to the middle of 2016.
