Note. The table is used to recalculate resistances at heating temperatures. For example, to calculate the resistance at a temperature of 44 ° C, it is necessary to take a temperature of 40 ° C vertically and a correction of 4 ° C horizontally: a change in resistance is obtained by 1,116 times.

Solidification of bulk substances 30.04.2024

There are quite a few mysteries in the world of science, and one of them is the strange behavior of bulk materials. They may behave like a solid but suddenly turn into a flowing liquid. This phenomenon has attracted the attention of many researchers, and we may finally be getting closer to solving this mystery. Imagine sand in an hourglass. It usually flows freely, but in some cases its particles begin to get stuck, turning from a liquid to a solid. This transition has important implications for many areas, from drug production to construction. Researchers from the USA have attempted to describe this phenomenon and come closer to understanding it. In the study, the scientists conducted simulations in the laboratory using data from bags of polystyrene beads. They found that the vibrations within these sets had specific frequencies, meaning that only certain types of vibrations could travel through the material. Received ... >>

Implanted brain stimulator 30.04.2024

In recent years, scientific research in the field of neurotechnology has made enormous progress, opening new horizons for the treatment of various psychiatric and neurological disorders. One of the significant achievements was the creation of the smallest implanted brain stimulator, presented by a laboratory at Rice University. Called Digitally Programmable Over-brain Therapeutic (DOT), this innovative device promises to revolutionize treatments by providing more autonomy and accessibility to patients. The implant, developed in collaboration with Motif Neurotech and clinicians, introduces an innovative approach to brain stimulation. It is powered through an external transmitter using magnetoelectric power transfer, eliminating the need for wires and large batteries typical of existing technologies. This makes the procedure less invasive and provides more opportunities to improve patients' quality of life. In addition to its use in treatment, resist ... >>

The perception of time depends on what one is looking at 29.04.2024

Research in the field of the psychology of time continues to surprise us with its results. Recent discoveries by scientists from George Mason University (USA) turned out to be quite remarkable: they discovered that what we look at can greatly influence our sense of time. During the experiment, 52 participants took a series of tests, estimating the duration of viewing various images. The results were surprising: the size and detail of the images had a significant impact on the perception of time. Larger, less cluttered scenes created the illusion of time slowing down, while smaller, busier images gave the feeling of time speeding up. Researchers suggest that visual clutter or detail overload can make it difficult to perceive the world around us, which in turn can lead to faster perception of time. Thus, it was shown that our perception of time is closely related to what we look at. Larger and smaller ... >>

A new way to determine distances in space 19.09.2015

Scientists from the University of Cambridge (UK) have come up with a new way to determine the distances to stars based on identical spectral characteristics.

Astronomers have taken as a basis a fairly simple principle: if two stars have exactly the same structure and chemical composition, then the intensity of their glow should also be identical. Accordingly, the difference in the distance to the stars should affect their brightness.

During the study, high-resolution spectra of 600 stars were analyzed, as a result of which 175 pairs of "twins" were found, and in each pair the distance to one of the celestial bodies was known with high accuracy.

To compare the spectra, the British chose 400 main spectral bands out of the available 280 and found that the proposed method gives an error of no more than eight percent compared to measurements based on the annual stellar parallax.
