How did Saudi Arabia disprove the idea of the devilish origin of the phone?

When the first telephone line in the country was laid in the palace of the king of Saudi Arabia, religious figures made a fuss: this diabolical invention of the infidels has no place on the land of Muslims!

However, King ibn Saud reasoned as follows: "If the phone is really a creation of Satan, then the holy words of the Koran will not be able to pass through the telephone wire. Let's take two mullahs, put them at different devices and ask them to read verses from the Koran in turn. If one can hear the other - so it's all right."

The result of the experiment removed all concerns, and since then the phone is allowed in Saudi Arabia.

Random interesting fact from the Great Encyclopedia:

Who is the author of the microscope?

The word "microscope" is a combination of two Greek words: "micros" (small) and "skopos" (observer). Thus, "microscope" means "observer of the small". This is a device used to see tiny objects invisible to the naked eye.

Usually an object appears larger the closer it is brought to the human eye. But if you bring it closer than 25 centimeters, it becomes unclear. Then they say it's out of focus. What if a convex lens is placed between the eye and the object? Then it can be brought to the eye closer than 25 centimeters, and it will be in focus.

Today we describe it simply as "using a magnifying glass". But ordinary magnifying glasses are really "simple microscopes" and have been known as such since time immemorial. So when we talk about the invention of the microscope, we really mean "compound microscope". At present, we only mean it when we talk about a microscope.

What is a "compound microscope"? In this type of microscope, magnification occurs in two stages thanks to two lenses. One of them, called the "lens", creates the original magnified image. The other, the "eyepiece", enlarges the first image.

In fact, there are several lenses in current microscopes, used for the objective as well as for the eyepiece. But the main thing is that all these microscopes are based on the principle of two-stage image magnification. The compound microscope was discovered sometime between 1510 and 1610. There is no exact information about the author of this discovery, and it is usually attributed to Galileo. Sometimes the "father of the microscope" is called the Danish scientist Leeuwenhoek, but this is due to many of his discoveries that he made using this device.

Leeuwenhoek showed that weevils, fleas and other small creatures hatch from eggs and are not "self-generating". He was the first to see such microscopic life forms as single-celled organisms and bacteria. With the help of a microscope he built with his own hands, he was the first to see the process of complete blood circulation.

Today it is difficult for a person to do without a microscope in almost any branch of science and industry.

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. ... >>

LG Tone Infinim Wireless Headset 21.05.2014

LG has announced its new device, created in collaboration with Harman Kardon. The novelty named Tone Infinim (HBS-900) is a wireless headset (Bluetooth 3.0; profiles A2DP, AVRCP, HFP, HSP).

Headphones, according to LG, have excellent sound quality and, first of all, will serve as a great addition to the smartphone LG G3, which will be announced in the very near future.

Of course, the novelty is compatible with any modern smartphone, but only in conjunction with the new flagship, the user will have access to features such as Name Alert and Answer Me +. The first is responsible for voicing the name or number of the subscriber of an incoming call, while the second will automatically turn off the headset if the user brings the smartphone to his ear during a call.

Also, the device is able to notify the user with vibration and sound the number of incoming messages, the current time and the remaining battery level, which, by the way, has a capacity of 220 mAh, which, according to LG, should be enough for 550 hours of standby time, 17 hours of talk time. and 14 hours of music playback.

Expect the appearance of a new model in the summer of 2014.
