Why does a magnetic compass show north incorrectly?

An ordinary magnetic compass shows north inaccurately, since the north magnetic pole does not coincide with the geographic one. Moreover, he is constantly moving from one place to another. Now it is still within the borders of the Canadian Arctic, but it is moving towards Taimyr at a speed of 64 kilometers per year.

What sunken ship became a source of metal for space satellites?

Steel for American satellites measuring cosmic radiation had to be mined from the Kronprinz Wilhelm ship sunk in 1919, because the radiation background from steel made after 1945 is too high.

Traffic noise delays the growth of chicks 06.05.2024

The sounds that surround us in modern cities are becoming increasingly piercing. However, few people think about how this noise affects the animal world, especially such delicate creatures as chicks that have not yet hatched from their eggs. Recent research is shedding light on this issue, indicating serious consequences for their development and survival. Scientists have found that exposure of zebra diamondback chicks to traffic noise can cause serious disruption to their development. Experiments have shown that noise pollution can significantly delay their hatching, and those chicks that do emerge face a number of health-promoting problems. The researchers also found that the negative effects of noise pollution extend into the adult birds. Reduced chances of reproduction and decreased fertility indicate the long-term effects that traffic noise has on wildlife. The study results highlight the need ... >>

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 ... >>

Look into the eyes of the phone 11.07.2003

It is about the appearance of machines that will understand human facial expressions and be controlled by it.

When the phone rings at the Human Communications Lab at Kingston University, Canada, the plush animal on the table next to the machine blinks and rolls its eyes. If the person sitting at the table breaks away from work and looks the little animal in the eyes, it will turn on the telephone, if not, the answering machine will work.

There are already cameras that focus on exactly the subject that the photographer is looking at. Canadian engineers propose to build similar systems into computers, mobile phones, voice recorders and other devices with which a person interacts.

The laboratory has created a table lamp that performs the verbal commands "Light up!" and "Extinguish!" only when the owner looks at her. That is, these words can be fearlessly used in a conversation, if it is not about a lamp.
