How is butter made?

Most of the butter sold in shops and markets is produced at oil mills that buy milk and sour cream from farmers.

After the sour cream is cleared of impurities, it is pasteurized. Most of the oil is produced from sweet sour cream. Sometimes pure sourdough is added to it - bacteria that produce lactic acid, mixed with other microorganisms. They help sour cream to ripen, to reach the desired condition. Sometimes dyes are added. Then the beating starts. It is produced in special rotating drums, where sour cream turns into a thick mass. Whipping takes about an hour. After that, the mixture is washed with water, the water drains. What remains is the oil.

Sometimes salt is added to the oil. The oil is kneaded mechanically until the desired density and water content are reached. Then the oil hardens, it is ready for packaging. Initially, it is packaged in large containers weighing about 30 kilograms. Then these packages are opened again and the oil is hung on the scales in any convenient quantities.

Man has been making oil since ancient times. It is mentioned many times in the Bible. In Proverbs 30-33: "Surely churning milk will produce butter." The Hindus used oil as early as 900 BC. e. It was part of their religious rites.

What role did dogs play in conquering the South Pole?

One of the decisive factors in Amundsen's victory over Scott in conquering the South Pole was the use of sled dogs. Moreover, Amundsen's plan considered them not only as a means of transportation. It was scheduled for the days when each dog should be shot, after which it became food for both people and other dogs. The total number of animals from the beginning of the expedition to the return to the base was reduced from 52 to 11.

A New Way to Control and Manipulate Optical Signals 05.05.2024

The modern world of science and technology is developing rapidly, and every day new methods and technologies appear that open up new prospects for us in various fields. One such innovation is the development by German scientists of a new way to control optical signals, which could lead to significant progress in the field of photonics. Recent research has allowed German scientists to create a tunable waveplate inside a fused silica waveguide. This method, based on the use of a liquid crystal layer, allows one to effectively change the polarization of light passing through a waveguide. This technological breakthrough opens up new prospects for the development of compact and efficient photonic devices capable of processing large volumes of data. The electro-optical control of polarization provided by the new method could provide the basis for a new class of integrated photonic devices. This opens up great opportunities for ... >>

Primium Seneca keyboard 05.05.2024

Keyboards are an integral part of our daily computer work. However, one of the main problems that users face is noise, especially in the case of premium models. But with the new Seneca keyboard from Norbauer & Co, that may change. Seneca is not just a keyboard, it is the result of five years of development work to create the ideal device. Every aspect of this keyboard, from acoustic properties to mechanical characteristics, has been carefully considered and balanced. One of the key features of Seneca is its silent stabilizers, which solve the noise problem common to many keyboards. In addition, the keyboard supports various key widths, making it convenient for any user. Although Seneca is not yet available for purchase, it is scheduled for release in late summer. Norbauer & Co's Seneca represents new standards in keyboard design. Her ... >>

The world's tallest astronomical observatory opened 04.05.2024

Exploring space and its mysteries is a task that attracts the attention of astronomers from all over the world. In the fresh air of the high mountains, far from city light pollution, the stars and planets reveal their secrets with greater clarity. A new page is opening in the history of astronomy with the opening of the world's highest astronomical observatory - the Atacama Observatory of the University of Tokyo. The Atacama Observatory, located at an altitude of 5640 meters above sea level, opens up new opportunities for astronomers in the study of space. This site has become the highest location for a ground-based telescope, providing researchers with a unique tool for studying infrared waves in the Universe. Although the high altitude location provides clearer skies and less interference from the atmosphere, building an observatory on a high mountain poses enormous difficulties and challenges. However, despite the difficulties, the new observatory opens up broad research prospects for astronomers. ... >>

Peaceful sleep mannequin 20.12.2008

At the University of the Bundeswehr (Hamburg, Germany), experiments are underway to create an "island of silence" in any apartment.

Thirty microphones, placed above the bed in which the mannequin lies, pick up ambient noise and feed it to a computer that synthesizes similar sound vibrations, but in antiphase. They are emitted through two speakers at the headboard. As a result, the sounds cancel each other out, and the microphones built into the mannequin's head show that the noise becomes quieter by 10 decibels.

The authors of the work say that so far it is not possible to suppress rapidly changing noises, for example, from a car passing under a window.
