The cathode ray tube or CRT, invented by Karl Ferdinand Braun, is the display device used in most computer displays, video monitors, televisions and oscilloscopes.

Cathode rays are streams of high-speed electrons emitted from the heated cathode of a vacuum tube. In a cathode ray tube, the electrons are carefully directed into a beam, and this beam is deflected by a magnetic field to scan the surface at the viewing end (anode), which is lined with phosphorescent material (usually based on transition metals or rare earths). When the electrons hit this material, light is emitted.

Note in the above description that the electrons are directed by use of magnetic fields... Because of this, when two monitors are placed side by side they have a momentary interference caused by the magnetic field of the other monitors. The interference is actually not only momentary, but constant and you can mostly not notice it.

So, from what we have learned today, can we conclude that the labs are not high quality as Rachael suggested?

The answer is yes. If the lab was high quality, the monitors would be LCD or Liquid Crystal Display monitors, like I have. If those monitors were extremely high quality, they would have shielding in them. However, nobody really puts shielding in monitors because it is too expensive and they pump those suckers out like turds at a prune festival.

This has been another addition of Dusty Sucks.
