Malfunctions in what household system explain many phenomena from the category of a haunted house?

Many phenomena from the category of "haunted houses" are explained only by a poorly functioning heating system, which causes carbon monoxide poisoning in residents in low concentrations. The symptoms of such poisoning, in addition to headaches and fatigue, also include visual and auditory hallucinations.

What is Churchill angry at in his most famous photograph?

One of the most famous photographs of Churchill, depicting him sullen and angry, was taken in 1941 after his speech to the Canadian House of Commons. When Churchill was brought into the room, he told the photographer that he had two minutes and lit a cigar. At the request of the photographer to remove the cigar, the prime minister refused. Then the photographer approached Churchill under the pretext of measuring the level of light and pulled the cigar out of his mouth himself, and the Prime Minister's reaction to this impudence was just caught on camera. But then Churchill smiled and allowed another photograph to be taken, although this benevolent photograph is far less known.

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 ... >>

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. ... >>

Total Surveillance in New York 24.08.2012

The New York Police Department has launched a revolutionary video surveillance system that will seriously complicate the life of intruders. The new system does more than just record incidents, it is able to scan the streets, identify vehicles and faces of suspects, monitor them throughout the city, and alert law enforcement agencies of suspicious activity in a timely manner.

Microsoft's Domain Awareness System is an innovative tool that will revolutionize law enforcement, intelligence and public safety, police say.

Unlike a simple network of CCTV cameras, the new system immediately gives the police a huge amount of information about the situation in the area under their control. For example, the Domain Awareness System can identify a recidivist who "looks" at the door of a jewelry store, and a police officer at that moment can get detailed data about his criminal past, a video of his detention and decide whether to send a patrol car to the bank, and how high the risk that the suspect will actively resist. In addition, you can connect the suspect to a specific vehicle, such as a taxi, and trace his route.

With regard to terrorism, this means that you can find where the person who was caught at the airport with the help of an explosive trace detector left a bomb bag. The entire path of a terrorist can be "rewound" back without extra time for interrogations and in a timely manner to detect the site of an upcoming terrorist attack or an underground laboratory.

About 3 video cameras are currently connected to the Domain Awareness System, most of which are located in the downtown area of ​​Manhattan. The network is constantly expanding to other areas of New York.
