Imaginary particles. Explaining tangible things...
Tangible products—like a solar-powered hearing aid—may come from not-so-real particles. More particular, scientists analyze the behaviour of modern materials with the help of imaginary structures called quasiparticles. (1) In physics, quasiparticles and collective excitations (which are closely related) are emergent phenomena that occur when a microscopically complicated system such as a solid behaves as if…

Illusions...
Expanding and contracting circles, mutating colors, and false image matches dominated the 2014 Best Illusion of the Year Contest, held on May 18th in the TradeWinds Island Grand in St. Petersburg, FL. One thousand perceptual scientists joined artists and the general public to determine the TOP THREE illusion masters from a pre-selected group of TOP…

Reality. In HD...
The world is our playground – especially when it is scanned and replicated exactly in a video game. A wave of new games use a technique called photogrammetry to produce digital replicas of the real world. The technique can be used to recreate rooms, objects, streets and even whole cities, says Krzysztof Plonka of special-effects…

Akinetopsia. Time stopping. Feeling the Cosmos. [Time as a prerequisite for Existence]
It started as a headache, but soon became much stranger. Simon Baker entered the bathroom to see if a warm shower could ease his pain. “I looked up at the shower head, and it was as if the water droplets had stopped in mid-air”, he says. “They came into hard focus rapidly, over the course…

Black holes. Magnetism. Fields.
A new study of supermassive black holes at the centers of galaxies has found magnetic fields play an impressive role in the systems' dynamics. In fact, in dozens of black holes surveyed, the magnetic field strength matched the force produced by the black holes' powerful gravitational pull. (1) Magnetic fields seem to be everywhere. It…
