The Smallest Black Hole in the Universe (Synopsis)

A binary system containing a stellar-mass black hole called IGR J17091. The strong gravity of the black hole, on the left, is pulling gas away from a companion star on the right. This gas forms a disk of hot gas around the black hole, and the wind is driven off this disk(Credit: NASA/CXC/M.Weiss)

How the Aged Vacuum Tube Could Save Moore’s Law

One of the bulbs Thomas Alva Edison used to discover thermionic emission (the Edison Effect) in 1884. Edison found when he connected an ammeter between the filament and the auxiliary electrode, a current would flow, passing through the evacuated space of the bulb from filament to electrode. This current was later found to consist of electrons.
