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-...
My son, for example, has a glow-in-the-dark yo-yo, a glow-in-the-dark ball, a glow-in-the-dark mobile and even (if you can believe it) a pair of glow-in-the-dark pajamas! They make him easy to find at night! If you have ever seen any of these products, you know that ...
Physics of Wave Phenomena is a peer-reviewed journal that publishes original contributions in wave processes across various subfields of physics. Covers a ...
They're skeptical of it being made by heavy atoms, which are hurled through space by violent astrophysical processes, hitting other heavy atoms in the process [source: Jaffe]. Edward Farhi, an MIT physicist who researched strangelets, thinks the most likely place to find strange matter is in...
If you want to see a hologram, you don't have to look much farther than your wallet. There are holograms on most driver's licenses, ID cards and credit cards. If you're not old enough to drive or use credit, you can still find holograms around your home. They're part of...
It is important to understand that this is not an "either/or" situation. Duality means that the characteristics of both waves and particles are present at the same time. The same beam of light will behave as a particle and/or as a wave depending on the experiment. Furthermore, the ...
the wave or its speed and frequency. For physics or chemistry students, learning to calculate a wavenumber forms a vital part of mastering the subject. The good news is that there is a simple formula for the wavenumber, and you need only very basic information about the wave to calculate ...

The amount of drag that your hand creates depends on a few factors, such as the size of your hand, the speed of the car and the density of the air. If you were to slow down, you would notice that the drag on your hand would decrease. We see another example of drag reduction when...
To lift the balloon, the pilot moves a control that opens up the propane valve. This lever works just like the knobs on a gas grill or stove: As you turn it, the flow of gas increases, so the flame grows in size. The pilot can increase the vertical speed by blasting a larger ...
