Clean Data! Unfiltered voltage recordings from cat primary visual cortex. This shows about a half second of activity on four separate electrodes separated by a few millimeters in response to a visual stimulus. Low frequency (local field potential) oscillations are clearly visible in the raw trace and correspond to the aggregate synaptic activity... - http://unclegrandpapants.com/post...
Holographic generation of an electron Airy beam. An electron beam is transmitted through a nanofabricated hologram, with a cubic phase modulation. It is then focused by a magnetic lens. The Airy wave packet is formed at the back focal plane and recorded as it propagates. The electron Airy beam is a shape-preserving beam that evolves along a curved... - http://unclegrandpapants.com/post...
The behavior of large and complex aggregates of elementary particles, it turns out, is not to be understood in terms of a simple extrapolation of the properties of a few particles. Instead, at each level of complexity entirely new properties appear. - http://unclegrandpapants.com/post...
RT @GreatDismal: Describing moment to moment reality, in char. POV, in a future with even moderately advanced connectivity, is a surprising amount of work.
