The wavefunction is a central mathematical entity in quantum physics. It is used to completely describe the state of a system. A means of probing it directly is now on hand. See Letter p.188doi:10.1038/474170aHostenOnurNatureHosten, O. How to catch a wave[J]. Nature, 2011, 474: 170-...
The wavelength of light is the distance from one peak of the wave to the next. This relates to the wave's frequency, or the number of waves that pass a point in a given period of time. The frequency of light determines its color and is measured in cycles per second, or Hertz (Hz)...
these bombs penetrate deep into the earth or right through a dozen feet of reinforced concrete before exploding. These bombs have made it possible to reach and destroy facilities that would have been impossible to attack otherwise.
The rate of particle collision— if more particles collide in a period of time, then more energy is transferred to an object. The force of the impact — if the particles hit with greater force, more energy is transferred to an object. These factors are determined by how many air particles...
aIt is therefore impor- tant to know how to decrypt the underlying physics of each elastography method in order to understand their advan- tages and physical limitations. Shear wave based techniques have strong advantages over quasi-static techniques, as they are more reproducible, quantitative, rel...
of preserving a good signal-to-noise ratio, and ensuring that the high frequency corner is below the earthquake corner frequencies. Adopting these smoother conditions implies that not all discussed cases may be strictly considered anti-repeaters, but some may correspond to quasi anti-repeaters and,...
UCL has recently launched a quantum computing and quantum communications CDT where students will undergo a six-month training period before writing their project proposal. She thinks this enables them to get the most out of their research, particularly if they haven’t covered some topics in their...
period of 1992-2012. Various tests have been performed to determine the changes in the sound quality and the healthcare concerns regarding hearing safety standards. Twenty-five different musicians have been tested by the audiology specialists with the same set of measures and methods to set an ...
No-one really knows what light is like, but scientists have settled on the idea that it has a sort of split personality. They like to call this wave-particle duality, but the basic idea is much simpler than it sounds. Sometimes light behaves like a train of waves—much like waves ...
Quantum computing uses phenomena in quantum physics to create new ways of computing. Quantum computing involves qubits. Unlike a normal computer bit, which can be either 0 or 1, a qubit can exist in a multidimensional state. The power of quantum computers grows exponentially with more qubits. ...
