The Black Hole of What?
In networking, black holes refer to places in the network where incoming traffic is silently discarded (or “dropped”), without informing the source that the data did not reach its intended recipient. When examining the topology of the network, the black holes themselves are invisible, and can only be detected by monitoring the lost traffic; hence…

Schumann resonance
[youtube http://www.youtube.com/watch?v=6MBwbcdy6qk%5D At any given moment about 2,000 thunderstorms roll over Earth, producing some 50 flashes of lightning every second. Each lightning burst creates electromagnetic waves that begin to circle around Earth captured between Earth’s surface and a boundary about 60 miles up. Some of the waves – if they have just the right wavelength…

Mirror Neurons
Neuroscientific evidence suggests that one basic entry point into understanding others’ goals and feelings is the process of actively simulating in our own brain the actions we observe in others. This involves the firing of neurons that would be activated were we actually performing an action, although we are only observing it in someone else.…

The Incandescent Sun
[youtube http://www.youtube.com/watch?v=yAO9QVrEa-E%5D This video takes SDO images and applies additional processing to enhance the structures visible. While there is no scientific value to this processing, it does result in a beautiful, new way of looking at the sun. The original frames are in the 171 Angstrom wavelength of extreme ultraviolet. This wavelength shows plasma in…

Hypercomputation
Hypercomputation or super-Turing computation refers to models of computation that go beyond, or are incomparable to, Turing computability. This includes various hypothetical methods for the computation of non-Turing-computable functions, following super-recursive algorithms (see also supertask). The term “super-Turing computation” appeared in a 1995 Science paper by Hava Siegelmann. The term “hypercomputation” was introduced in 1999…

Digital Physics
In physics and cosmology, digital physics is a collection of theoretical perspectives based on the premise that the universe is, at heart, describable by information, and is therefore computable. Therefore, the universe can be conceived as either the output of a computer program or as a vast, digital computation device (or, at least, mathematically isomorphic…
