Physics and Numbers
The fastest quantum computer bit that exploits the main advantage of the qubit over the conventional bit has been demonstrated by researchers at University of Michigan, U.S. Naval Research Laboratory and the University of California at San Diego.
The field of particle physics is poised to enter unknown territory with the startup of a massive new accelerator--the Large Hadron Collider (LHC)--in Europe this summer. On September 10, LHC scientists will attempt to send the first beam of protons speeding around the accelerator.
Knowing the words for numbers is not necessary to be able to count, according to a new study of aboriginal children. The study of the aboriginal children – from two communities which do not have words or gestures for numbers – found that they were able to copy and perform number-related tasks.
If wind turbines clatter and whistle too loudly, they are only permitted to operate under partial load to protect the local residents – but this also means a lower electricity output. An active damping system cancels out the noise by producing counter-vibrations.
Milliseconds can mean the difference between triumph and defeat in the world of Olympic sports, leading more trainers and athletes to look toward technology as a tool to get an edge on the competition.
"Ye canna change the laws of physics!" Scotty warned Captain Kirk on "Star Trek." But engineers and physicists at the University of Maryland may rewrite one of them.
Thought experiment: a carbon dioxide molecule—think of a cheerleader’s baton—comes slanting in at high speed over a dense liquid, strikes the surface and ricochets. How does it tumble?
A new study is shedding light on an important, unsolved physics problem: the relationship between chaos theory – which is based on 300-year-old Newtonian physics – and the modern theory of quantum mechanics.
Scientists have studied superconductors and superfluids for decades. Now, researchers have drawn the first detailed picture of the way a superfluid influences the behavior of a superconductor. In addition to describing previously unknown superconductor behavior, these calculations could change scientists' understanding of the motion of neutron stars.
Judged by the astonishing increase in journal papers written by scientists in China, there can be little doubt that China is finding its place as one of the world's scientific power houses. Michael Banks, Physics World's News Editor, quantifies this surge in scientific output from China and asks whether quality matches quantity in August's Physics World.
I am so curious about dimension. Why an ant could not see three-dimension?
Light is still reflected to its eyes. Does 4th dimension mean time?
The Viterbi Algorithm, the elegant 41-year-old logical tool for rapidly eliminating dead end possibilities in data transmission, has a new application to go alongside its ubiquitous daily use in cell phone communications, bioinformatics, speech recognition and many other areas of information technology.
Scientists at the University of California, Berkeley, have devised a way to squeeze light into tighter spaces than ever thought possible, potentially opening doors to new technology in the fields of optical communications, miniature lasers and optical computers.
Atoms derive from the precise collisions of frequencies in the universal force field from every direction which momentarily arrests the speed of light. A precise collision of frequencies at the positive peak creates a proton. The precise collision of frequencies at the negative peak creates an electron. The precise collision of frequencies at zero peak produces a neutron.
Most of us would agree that 32 degrees Fahrenheit (F), the temperature at which water freezes, is a pretty cold day, but what about minus 320 degrees F, the boiling point of nitrogen ... or minus 452 degrees F, the boiling point of helium?
