The National Science Foundation report also discovered that the US, Russia and Japan have the lowest number of patents awarded to foreign inventors. In all the other countries surveyed, over two-thirds of each countries patents went to foreign inventors. One reason for the low number of foreign-held Japanese patents is the high cost of translating […]
Richard Canfield and David McKenzie from Montana State University in the US, and Hugh Hudson from the Solar Physics Research Corporation in Japan, analysed two years worth of images from the X-ray satellite Yohkoh. In addition to the link between sigmoids and solar flares, they also confirmed that there was a link between solar flares […]
Tai Chang Chiang and co-workers at Urbana confined electrons in thin films of silver ranging from 1 monolayer to around 100 monolayers thick. Just as photons resonate back and forth in an optical Fabry-Perot interferometer, the Urbana team showed that electrons bounced back and forth from the two surfaces of the silver film. They used […]
Last Monday Fermilab issued a press release titled “Fermilab physicists find new matter-antimatter asymmetry”. On Thursday CERN replied with a statement which read: “The CERN physics community offers its congratulations to their colleagues from the KTeV experiment at Fermilab for their exciting new data on the observation of direct CP violation in neutral kaon decays […]
Witherell received his PhD from the University of Wisconsin in 1973 and became an assistant professor at Princeton University in 1975. He moved to Santa Barbara in 1981 and in 1990 won the American Physical Society’s Panofsky Prize for experiments on charm quarks at Fermilab. Witherell has also been chair of the Department of Energy’s […]
“Heisenberg is an intelligent man, but a typical German (that is to say a Tacitus).” So wrote Albert Einstein to his Swiss confidant Carl Seelig, in January 1953. Although the quotation does not appear in this book by the American historian Paul Rose, everything else that one could possibly say against Werner Heisenberg and his […]
Seaborg shared the 1951 Nobel Prize for Chemistry with the physicist Edwin McMillan. In addition to a long career at the University of California and the Lawrence Radiation Laboratory, both in Berkeley, Seaborg was also chancellor of the University of California and head of the Atomic Energy Commission. During the Second World War he was […]
In Fink and Mao’s method the space surrounding the tie is split into three sections: left, centre and right. To begin the wide end of the tie is passed either over or under the narrow part. The knotting process then continues with a series of half turns or moves either towards or away from the […]
Some asteroids are pulled into near-Earth orbits by gravitational resonance effects created by the combined pulls of Mars, Jupiter and Saturn. However, it has been known for many years that another mechanism must be pulling asteroids out of their more typical Mars- Jupiter orbit. Farinella and Vokrouhlicky suggest that when large asteroids collide, their fragments […]
