Slow light is a dramatic reduction in the group velocity of light, not the phase velocity. Slow light effects are not due to abnormally large refractive indices, as will be explained below. The simplest picture of light given by classical physics is of a wave or disturbance in the electromagnetic field.
Hau and her associates at Harvard University "have demonstrated exquisite control over light and matter in several experiments, but her experiment with 2 condensates is one of the most compelling". [11] In 2006 they successfully transferred a qubit from light to a matter wave and back into light, again using Bose–Einstein condensates.
Experiments that attempt to directly probe the one-way speed of light independent of synchronization have been proposed, but none have succeeded in doing so. [3] Those experiments directly establish that synchronization with slow clock-transport is equivalent to Einstein synchronization, which is an important feature of special relativity.
OpenRelativity is a toolkit designed for use with the proprietary Unity game engine. It was developed by MIT Game Lab during the development of A Slower Speed of Light. The toolkit allows for the accurate simulation of a 3D environment when light is slowed down. [7] It is hosted on GitHub and has been published under the permissive MIT license. [2]
If you travelled a year at 95% the speed of light; you'd age one year, and people on Earth would age 3.2 years! But if you were going 50% the speed of light it would only be 1.15 years. The effect ...
The Antiproton Cell Experiment (ACE), AD-4, started in 2003. It aims to assess fully the effectiveness and suitability of antiprotons for cancer therapy. The results showed that antiprotons required to break down the tumor cells were four times less than the number of protons required. The effect on healthy tissues due to antiprotons was ...
The newly released fast neutrons, moving at roughly 10% of the speed of light, must be slowed down or "moderated", typically to speeds of a few kilometres per second, if they are to be likely to cause further fission in neighbouring 235 U nuclei and hence continue the chain reaction. This speed occurs at temperatures in the few hundred Celsius ...
Soaking your shower head in vinegar overnight. Grandma isn't completely wrong here. However, we'd like to offer a modification to the process of cleaning your shower head with vinegar.
