This area deals with the fundamental laws and building blocks of nature and how they interact, the properties and the behavior of matter, and research into space and time and their structures.
innovations-report provides in-depth reports and articles on subjects such as astrophysics, laser technologies, nuclear, quantum, particle and solid-state physics, nanotechnologies, planetary research and findings (Mars, Venus) and developments related to the Hubble Telescope.
Physicists in the UK are ready to start construction of a major part of an advanced new experiment, designed to search for elusive gravitational waves. They are already part of two experiments: the UK/German GEO 600 project and the US LIGO experiment (Laser Interferometer Gravitational-Wave Observatory), both in their commissioning phases. By bringing GEO 600 technology to LIGO, they and their German colleagues from the Albert Einstein Institute are now set to become full partners in Advanced LIGO, a
St. Petersburg researchers have designed an original thermometer for fast-moving electrons in thermonuclear reactors. The laser beam in this device is used to instantly determine the temperature of burning hot plasma, at frequencies required for precise diagnostics.
This device is a further step forward to controlled nuclear fusion. The device will help researchers to get precise information about energy distribution of hot plasma electrons inside the tokamac – the most promising current pro
Astronomers using NASAs Hubble Space Telescope have discovered three of the faintest and smallest objects ever detected beyond Neptune. Each lump of ice and rock is roughly the size of Philadelphia and orbits just beyond Neptune and Pluto, where they may have rested since the formation of the solar system 4.5 billion years ago. The objects reside in a ring-shaped region called the Kuiper Belt, which houses a swarm of icy rocks that are leftover building blocks, or “planetesimals,” from the sola
Carbon nanotubes, recently created cylinders of tightly bonded carbon atoms, have dazzled scientists and engineers with their seemingly endless list of special abilities – from incredible tensile strength to revolutionizing computer chips. In todays issue of Science, two University of Rochester researchers add another feat to the nanotubes list: ideal photon emission.
“The emission bandwidth is as narrow as you can get at room temperature,” says Lukas Novotny, professor of
UCLA astronomers report they have detected remarkably stormy conditions in the hot plasma being pulled into the monstrous black hole residing at the center of our Milky Way galaxy, 26,000 light years away. This detection of the hot plasma is the first in an infrared wavelength, where most of the disturbed plasmas energy is emitted, and was made using the 10-meter Keck II Telescope at the W.M. Keck Observatory in Hawaii.
Plasma is a hot, ionized, gas-like matter — a fourth state of ma
Researchers studying physical and chemical processes at the smallest scales, smaller even than the width of a human hair, have found that fluid circulating in a microscopic whirlpool can reach radial acceleration more than a million times greater than gravity, or 1 million Gs.
By contrast, a pilot flying a fighter jet at high speed and in relatively tight circular patterns might experience a force of 10 to 12 Gs, making the force his body feels 10 to 12 times normal.
