How do peanuts grow?

If you look at a closed peanut pod, you will see that it is very similar to peas or beans. Indeed, the peanut belongs to the same family.

Peanuts grow in bushes, and its flowers resemble pea flowers. When the petals wither, part of the pod greatly increases in length, and its tip sinks into the soil. There, this tip increases, and the seeds ripen. Therefore, if you want to collect nuts, you must dig them out of the ground! Where did peanuts come from? Perhaps their homeland is South America. This is a very old plant.

Peanuts have been found in prehistoric graves in Peru along with utensils decorated with peanut ornaments. From there, they probably made their way to Africa, and then to the United States. Today, peanuts are grown in the US South from Florida to California, as far north as Washington, the US capital. They are also cultivated in Latin America, Asia and Africa. Common varieties of peanuts are Virginian nuts with large pods and red skins, as well as smaller ones - Spanish and North Carolina.

Peanuts need a long frost-free period for normal growth. The peanut is able to withstand long dry spells and is a profitable crop that yields 100 to 150 hectoliters per hectare.

Peanuts are used to make nut butter, salted or roasted, and used in confectionery. But they apply in many other cases as well. Walnut oil is added to vegetable salads, soups, margarines. Peanuts are fed to domestic animals. They are used in paints, inks and rubber substitutes.

Nuts are planted in late autumn and dug up by machines before frost. After drying the pods, they are also husked by machines. Sometimes pigs are released into the fields to dig up nuts.

Random interesting fact from the Great Encyclopedia:

Why are the Chinese not naturally adapted to drinking milk?

The human body digests milk thanks to a special enzyme - lactase, which was originally produced only in the body of infants in order to drink mother's milk. However, some people had a "defect" that allowed the enzyme to be produced in their intestines all their lives. It was the ability to drink milk that gave them a competitive advantage among northern Europeans who were deficient in calcium and vitamin D. Gradually, this gene spread, and today the number of inhabitants of northern European countries with lactose intolerance does not exceed 10%. And among the Chinese, residents of Southeast Asia, Africa, American Indians, this figure is above 90%.

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 ... >>

Beam of cold atoms without laser cooling 26.01.2023

American physicists managed to obtain lithium atoms with a temperature of 10 millikelvins by cooling them in a stream of helium gas and trapping them in a magnetic trap. In terms of efficiency, their method turned out to be no worse than laser cooling, but it can be used with a large number of types of atoms and expand the area of application of cold atomic beams.

It is much easier for experimental physicists to work with atoms, ions and molecules in a chilled state. Cooling down to temperatures below one kelvin minimizes the kinetic energy of the particles, making them more controllable. So they can be sharpened into traps, used for high-precision measurement experiments, such as atomic interferometry, as well as studying quantum phenomena and exotic forms of matter.

In their new experiment, physicists at the University of Texas at Austin have proposed a new way to produce continuous beams of cooled atoms.

The most used method for cooling atoms is laser cooling, which relies on the absorption of light by atoms. A properly chosen frequency below the resonant transition in the atom will cause the particle to waste its kinetic energy, slow down, and eventually cool down. However, despite the success of the method, it is not suitable for all atoms, and also imposes restrictions on some experiments with particles.

Another way to obtain cold beams of atoms and molecules is to use a buffer gas. The buffer gas cooling method works by dissipating the energy of the particles of interest through elastic collisions with cold atoms of an inert gas, such as helium or neon. Since this cooling mechanism does not depend on the internal structure of the particles (unlike laser cooling), buffer gas cooling is applicable to almost any atom or small molecule.

The beam temperature of the resulting atoms is typically in the range of one to several kelvins. Lower temperatures can be achieved using supersonic jets of inert gases, with which the particles are cooled by the adiabatic expansion of the carrier gas.

In their work, the scientists decided to combine the advantages of both methods and created a beam of lithium-7 atoms, which cooled to 10 millikelvins in a chamber with a helium-cooled expansion, releasing a supersonic jet.

In the researchers' experiment, helium-4 gas is fed at supersonic speed into a small cylindrical cell, where it is cooled to a temperature of 4,4 kelvin. A beam of lithium is directed into the helium flow, some of whose atoms are captured by the helium flow and cooled due to collisions with it. The expanded gas jet is redirected to the next vacuum chamber, and the lithium atoms are captured by a magnetic hexapole lens, which focuses them by influencing the magnetic moment. Helium atoms are not focused by a magnet and therefore continue to move in ballistic trajectories until they hit the surface.

So scientists can get the maximum flow of lithium atoms at the lowest possible temperature. The experimenters note that an improved chamber design could increase the flux tenfold, and the approach itself could be adapted to other atoms and molecules, which the scientists plan to test in future work.
