Two Experiments Show Fourth Spatial Dimension Effect

To the best of our knowledge, we humans can only experience this world in three spatial dimensions (plus one time dimension): up and down, left and right, and forward and backward. But in two physics labs, scientists have found a way to represent a fourth spatial dimension.

Leaving flatland – quantum Hall physics in 4-D

In literature, the potential existence of extra dimensions was discussed in Edwin Abbott’s satirical novel “Flatland: A Romance of Many Dimensions” (1884), portraying the Victorian society in 19th century England as a hierarchical two-dimensional world, incapable of realizing its narrow-mindedness due to its lower-dimensional nature.

Electron spin changes as a general mechanism for general anesthesia?

(Phys.org) -How does consciousness work? Few questions if any could be more profound. One thing we do know about it, jokes biophysicist Luca Turin, is that it is soluble in chloroform. When you put the brain into chloroform, the lipids that form nerve cell membranes and the myelin that insulates them will dissolve. On the other hand, when you put chloroform into the brain, by inhaling it, consciousness dissolves. It is hard to imagine a satisfying explanation of consciousness that does not also account for how anesthetics like chloroform can abolish it.
