Which actor was forced to play in Harry Potter by his granddaughter?

Richard Harris, who played Albus Dumbledore in Harry Potter and the Philosopher's Stone, turned down the role three times because he was already seriously ill. His 11-year-old granddaughter found out about the offer and said she would never speak to her grandfather again if he turned down the role. Only after that Harris gave his consent to the shooting.

How do supporters of the Movement for the Voluntary Extinction of Humanity justify their goal?

There is the Movement for the Voluntary Extinction of Humanity, whose supporters believe that the population of our species is out of control and threatens all life on the planet. The way out of this situation, in their opinion, will be the complete extinction of Homo sapiens. To achieve this goal, you do not need to commit suicide or kill others - you just need to give up procreation.

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 ... >>

Tiny chip that controls multiple laser beams 17.04.2023

Engineers at the US National Institute of Standards and Technology have developed chip-scale devices to simultaneously control the color, focus, direction of movement, and polarization of multiple beams of laser light. The development is suitable for creating portable sensors and quantum devices.

Traditional optical systems, which allow even a single laser beam to be controlled, represent a large-scale structure the size of a dining table. It houses many lenses, polarizers, mirrors and other devices. To create portable sensors and quantum computers will require miniature chips.

The researchers combined two technologies at the chip level: photonic integrated circuits, using tiny transparent channels and other micro-components for light; and a source of unconventional optics known as the optical metasurface. Such surfaces are made up of glass plates with millions of tiny structures only a few hundred billionths of a meter high that manipulate the properties of light without the need for bulky optics.

The system for forming multiple laser beams (blue arrows) and controlling their polarization consists of three components: an evanescent coupler (EVC), which directs light from one device to another; meta-grid (MG), scattering light; and the metasurface (MS), a small glassy surface studded with millions of pillars that act as lenses.

In a series of experiments, the researchers demonstrated that a single photonic chip did the work of 36 optical components while simultaneously controlling the direction, focus, and polarization (the plane in which a light wave oscillates as it moves) of 12 laser beams, divided into four different colors. They also showed that a tiny chip could direct two beams of different colors to run in parallel. This is necessary to create atomic clocks.

The researchers note that they continue to work on a full-fledged optical system based on the chip. So far, laser light is not yet powerful enough to cool atoms to the ultra-low temperatures required for miniature advanced atomic clocks.
