Focus Description:

Tell the audience that it's going to rain. Take an umbrella, open it and hold it above your head. And it will really rain - drops of water will spill from the dome of the umbrella onto the floor! (Fig. a).

Focus Rain from under an umbrella

Focus secret:

The secret of the trick is in a small rubber can - in a rubber bulb - with water, which you discreetly hold in your hand. When opening the umbrella, quietly put the can on the tube coming out of the hollow handle of the umbrella. At the right moment, slowly press on the can, and the water will rush up the handle, and leaving the small holes of the upper sealed end of the umbrella, it will flow down the dome and, like rain, drip onto the floor (fig. b).

The speech of sperm whales is similar to that of humans 18.05.2024

In the world of the ocean, where the mysterious and unknown coexists with the studied, sperm whales, with their huge brains, are of particular interest to science. Researchers, working with a huge array of audio recordings collected during the Dominica Sperm Whale Project (DSWP) - more than 8000 recordings, seek to unravel the secrets of their communication and understand the structure and complexity of the language of these mysterious creatures. By studying in detail the recordings of 60 sperm whales in the eastern Caribbean, scientists have revealed surprising features of their communication, revealing the complexity of their language. "Our observations indicate that these whales have a highly developed combinatorial communication system, including rubato and ornaments, which indicates their ability to quickly adapt and vary during communication. Despite significant differences in evolution, sperm whales have elements in their communication that are characteristic of human communication," says Shane Gero, a biologist at Carleton University and director of the CETI project.

Electron spin for quantum information transfer 18.05.2024

The transfer of quantum information remains one of the key tasks of modern science. Recent advances in the use of electron spin to expand the capabilities of information transfer in quantum systems have become very important. Researchers at Lawrence Berkeley National Laboratory are pushing the frontiers of quantum information science by experimenting with the possibilities of electron spin. Electron spin, a natural quantum bit, is a potentially powerful means for storing and transmitting information in quantum systems. Magnon wave packets, collective excitations of electron spin, have revealed their potential to transmit quantum information over significant distances. The work of Berkeley Lab researchers has revolutionized the way such excitations propagate in antiferromagnets, opening up new prospects for quantum technologies. Using pairs of laser pulses, scientists disrupted antiferromagnetic order in one place and simultaneously studied it in another, creating ... >>

Sound-absorbing silk 17.05.2024

In a world where noise is becoming increasingly intrusive, the emergence of innovative materials that can reduce its impact is of great interest. MIT researchers have unveiled a new sound-absorbing silk fabric that promises to revolutionize quiet spaces. The Massachusetts Institute of Technology (MIT) has made significant breakthroughs in the field of sound absorption. Researchers have developed a special silk fabric that can effectively absorb sound and create cozy, quiet environments. The fabric, thinner than a human hair, contains a unique vibrating fiber that is activated when voltage is applied to it. This feature allows the fabric to be used to suppress sound waves in two different ways. The first method uses fabric vibrations to generate sound waves that cover and cancel out unwanted noise, similar to noise-canceling headphones. This p ... >>

To the stars on the printer 04.08.2001

A group of Chinese experts from Tsinghua University in Beijing proposed a steam engine for space flights based on the principle of a modern computer printer.

The engine consists of two wafers of silicon less than a square centimeter in area. One of the plates is engraved with a channel for water inflow and a "combustion chamber" where water evaporates when current pulses are applied to a titanium resistor. In another plate - a miniature nozzle (nozzle).

Droplets of water, evaporating explosively, create jets of steam that fly out of the nozzle at a speed of 28 meters per second. The energy for the engine can come from solar panels.

The steam engine is designed to control the orientation of small artificial satellites weighing up to a kilogram.
