Focus Description:

A handkerchief twisted at both ends stands directly on the index finger.

Focus secret:

When you twist the handkerchief, you have a white thin wire inside the handkerchief. It keeps the scarf upright. At the end of the trick, you can crumple the handkerchief and put it in your pocket.

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 ... >>

GNSS module L76L-M33 03.05.2020

The new L76L-M33 is a classic GPS/GLONASS/Galileo module with support for standard NMEA messages via UART interface.

The module is notable for its low cost, while it has excellent characteristics: sensitivity in the tracking mode is 167 dB, in the capture mode 149 dB. Such high parameters are achieved using a built-in low-noise amplifier, which allows the module to work with passive antennas without additional active components on the board.

For a better start after a long break, the receiver has a special technology EASY ™ (Embedded Assist System), which calculates the future position of the satellites based on previously received ephemeris. This allows for a quick start even when it is impossible to use auxiliary data received via additional communication channels.

To reduce consumption, the L76L-M33 implements a special AlwaysLocate mode of operation, which periodically turns off the receiver based on a compromise between current consumption and positioning accuracy.

The receiver operates in the operating voltage range from 2,8 to 4,3 V, consuming from 3 to 30 mA, depending on the operating mode. The frequency of NMEA lines output can be up to 10 Hz. The 1PPS output provides a timestamp referenced to UTC with an accuracy of 10 ns.

The GNSS receiver is recommended for automotive applications, wearable gadgets and precise time systems, energy meters and security devices.
