Optical Illusions: Afterimage science + ghosts

Have you ever seen a ghost? How about an after-image? Our bodies aren’t perfect and they sometimes make mistakes, resulting in fun optical illusions.

Sunsets are Illusions

By Steven Spence “It is sometimes said that scientists are unromantic, that their passion to figure out robs the world of beauty and mystery. But is it not stirring to understand how the world actually works — that white light is made of colors, that color is the way we perceive the wavelengths of light,[…] and that the sky is blue for the same reason that the sunset is red? It does no harm to the romance of the sunset to know a little bit about it.” (Carl Sagan, Pale…

Brain-like Computers from Optical Fibers

Computers that function like a human brain could soon become a reality thanks to new research using optical fibers made of speciality glass. This research has the potential to allow a faster and smarter brain-like computer that can learn and adapt. Researchers from the Optoelectronics Research Centre (ORC) at the University of Southampton, UK, and Centre for Disruptive Photonic Technologies (CDPT) at the Nanyang Technological University (NTU), Singapore, have demonstrated how neural networks and synapses in the brain can be reproduced with optical pulses as information carriers, using special fibers…

First Photo of Light as Wave and Particle

In 1905, Albert Einstein proposed that light has properties of both a wave and a stream of particles. Now, researchers in Switzerland have taken the first ever photo of light behaving both as a wave and as a stream of particles at the same time. The ability to observe light in this way could bring us a step closer to building super fast quantum computers, the researchers say. When UV light hits a metal surface it causes an emission of electrons. This is known as the photoelectric effect. A research…
