What are the origins of slow-light research and where is the field heading? Nature Photonics spoke to Robert Boyd to find out. Actually, ideas about slow and fast light go back at least 170 years.
Maxwell's equations didn't seem to allow light to slow down or stop when moving through space. Einstein's answer—that light's speed is constant for all observers regardless of their own velocity ...
Slow light is an electromagnetic wave with a group velocity reduced by optical resonances in the medium through which it is travelling. These resonances can occur in atomic vapours, in photonic ...
However, light *can* slow down slightly when it passes through an absorbing medium, like water (225,000 kilometers per second = 140,000 miles per second) or glass (200,000 kilometers per second ...
A series of new animations by a NASA scientist show just how zippy - and also torturously slow - the speed of light can be. Light-speed is the fastest that any material object can travel through ...

To master the art of slow eating, put on some music, light a few candles, turn off the TV and any other distractions, and concentrate on your meal. A perfect place to start is with dessert.
Have you ever returned from vacation and felt like you needed another vacation because you were so exhausted? Enter the slow ...
When it comes to capturing slow-moving clouds or car trails, that could be as much as 120 seconds. Many cameras have a noise reduction feature for capturing long exposures in low light, where unwanted ...
A weak vibration doesn't travel very far. Discover more about volume. All about light Learn how light travels and how we see different colours. What is light? Light comes from different sources ...
There are a lot of benefits of slow running, so much so that 80 percent of your runs should be at that easier, low-effort pace, while the other 20 percent can be more challenging like speed runs, ...
In this mind-bending series, Professor Jim Al-Khalili shows how by uncovering its secrets, scientists have used light to reveal the universe. There's a whole universe of science to discover from ...
