What was unique about Charles Creighton and James Hargis' road trip across the US?

In 1930, Americans Charles Creighton and James Hargis traveled by car from New York to Los Angeles and back. The highlight was that they covered the entire path (more than 11 thousand kilometers) in reverse.

Authors: Jimmy Wales, Larry Sanger

 Random interesting fact from the Great Encyclopedia:

Do any birds hibernate in the winter?

When the winter cold comes, we can close ourselves in our house, light a fire in the fireplace and sit by it until we feel like going outside. Although we are warm-blooded animals, we cannot hibernate. And if a person were capable of this, do you think he could not live longer, surviving the cold in this way? Birds, alas, also cannot hibernate. But still they are able to tolerate very low temperatures. Even a small canary, which may live in your cage, can tolerate outdoor temperatures down to minus forty-five degrees Celsius, if, of course, it has something to peck in sufficient quantities.

Birds that are able to get their own food and do not fly away to warm countries for the winter do not need hibernation. Falling into hibernation is determined by a special temperature-regulatory center in the brain. The body reacts to cold by sending the blood in the skin to the internal organs of the body, ruffling the fur or feathers to increase the heat-retaining layer, causing the animals to shiver, which also contributes to warmth. Hibernating animals simply "turn off" this thermostat in their bodies when it's time to fall asleep for the winter. They become almost cold-blooded animals. This process is caused by a decrease in external temperature, a lack of food, a shortening of the day, and other conditions.

When an animal goes into hibernation, its temperature regulator begins to falter: when the body temperature drops, it will not respond to it in the same way as in the normal state, with an increase in temperature. Instead, body temperature is brought into line with air temperature. Breathing becomes slow and irregular, like the heartbeat itself, and various nervous reflexes cease to function altogether.

If the air temperature drops below zero, some hibernating animals begin to breathe faster, and the body generates a little more heat. Some of them wake up. Those that do not react at all to a sharp drop in temperature can freeze to death.

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. ... >>
