What did you notice about the video above? Were you able to predict whether the coin landed on heads or tails? Or more importantly, did you notice that the coin itself was switched halfway through?
This is an exercise conducted by the University of South Carolina focusing on human processing of attended and unattended information, and how our brains can be tricked into filtering out information that is actually relevant.
This phenomenon is called ‘change blindness’ and, for better or worse, is the reason magicians exist.
Created by the online science museum, Emergent Universe, this flash mob illustrates the behaviour of electrons in a superconductor. As explained by the site:
In a metal, electrons flow like a gas through a grid of metal ions. When the temperature is above the critical temperature, Tc, and the superconducting material is in its normal, non-superconducting state, these electrons move nearly independently of one another. When the temperature drops below Tc and the material enters its superconducting state, these electrons, like the dancers here, pair up. The electron pairs can then lower the overall energy by synchronising their movements with the other pairs, such that all pairs move cooperatively torgether as a single, coherent entity.
This is what the successor to Google Earth would look like: Google Space!
This zoom sequence starts with a view of our home galaxy, the Milky Way, then zooms in towards the crowded center of the galaxy, in the direction of the constellation of Sagittarius the Archer. Then the scene shifts to an infrared view, which lets us see see through the dusty clouds in this direction and get a close-up view of objects orbiting the supermassive black hole at the heart of the Milky Way galaxy. The final views show the motion of a newly discovered gas cloud that is falling rapidly towards the central black hole.
Do you have a spare 4.5 minutes? Then I highly recommend you check out this video from NASA.
Focusing on the Earth’s magnetosphere and climate engine, the video follows a trail of energy that flows from the Sun into the Earth’s atmosphere, oceans, and biosphere - the three interacting systems that shape our climate.
It is based on real satellite data and computer simulations and is the result of two years of work drawing on the expertise of several collaborators.
SCIENCE has explained nothing; the more we know the more fantastic the world becomes and the profounder the surrounding darkness. Aldous Huxley, 1894-1963.
This blog resides firmly at the intersection of scientific research, education, art, and communication. Herein lies information and current happenings related to each, as well as any other sciencey goodness worth sharing.
