According to Yonatan Dubi and Massimiliano Di Ventra of the University of California, San Diego. They have calculated that provided some points along the wire’s length stay below the threshold temperature, the material will superconduct. For this to work, the wire’s surface must be extremely clean, allowing electrons to move freely and spread along the …
HPCWire highlights of SC09 * 15 of 60 press releases were GPU related* China’s GPU-CPU “Tianhe” supercomputer making it into the number 5 position on the TOP500* Japan’s 3 petaflop TSUBAME 2.0 Fermi-equipped super scheduled for deployment in October 2010* announcement of a new GPU computing collaboration network.* HPC-capable Fermi GPUs from NVIDIA coming online …
The Globe and Mail reports: Using ultrasound to examine the vessels leading in and out of the brain, Dr. Zamboni made a startling find: In more than 90 per cent of people with multiple sclerosis, including his spouse, the veins draining blood from the brain were malformed or blocked. In people without MS, they were …
Flight Global reports that european researchers developing a magnetic heat shield that could augment or replace the traditional ablative materials hope to make a test flight in the next decade. Under development by EADS Astrium, with support from German aerospace centre DLR and the European Space Agency, the magnetic field-protected vehicle will be launched from …
Electrical creation of spin polarization in silicon at room temperature Eventual commercialization will mean faster electronics that is far more energy efficient. The control and manipulation of the electron spin in semiconductors is central to spintronics which aims to represent digital information using spin orientation rather than electron charge. Such spin-based technologies may have a …
WISE is a NASA-funded Explorer mission that will provide a vast storehouse of knowledge about the solar system, the Milky Way, and the Universe. Among the objects WISE will study are asteroids, the coolest and dimmest stars, and the most luminous galaxies. WISE is an unmanned satellite carrying an infrared-sensitive telescope that will image the …
Here is speculation on top of speculation as we do not yet know what Dark Matter is or even have full agreement that it exists. The dark matter starship assumes that there is dark matter around and that the dark matter can be scooped up for fuel like Bussard Ramjet could scoop of hydrogen. They …
There are two main criticisms of focus fusion. 1. Hydrogen-boron fuel allows too much x-ray cooling * The hot plasma of this fuel will emit x-rays too quickly, * the energy lost through the x-rays will always be more than the energy gained by fusion reactions.* the fusion reactions would not heat the plasma suffieicntly, …
Picture from 2006 tests of a DC-X like rocket Jeff Bezos, CEO of Amazon.com, has a rocket company called Blue Origin The website for Blue Origin indicates plans for unmanned flights in 2011 and manned flights in 2012. Flight testing of prototype New Shepard vehicles began in 2006. Blue Origin expects the first opportunities for …
There are some rare individuals with IQs in the 200’s and their brains are not larger than regular people. Highest IQs Ever The dominate, rigorously researched, and documented answer (who had the highest IQ) is German polymath Johann von Goethe (IQ = 210), second to Shakespeare in literature, with a vocabulary of over 90,000 words, …
Physicists at UC Santa Barbara have made an important advance in electrically controlling quantum states of electrons, a step that could help in the development of quantum computing. In seperate research, another group controlled spin electronically The researchers have demonstrated the ability to electrically manipulate, at gigahertz rates, the quantum states of electrons trapped on …
