The electron had already been discovered. It took little imagination to "see" that the cathode ray was the beam of electrons that originated from the cathode. And the beam was controlled using techniques based directly on what was correctly understood about the electron. The cathode ray could only be an electron beam generated at the cathode. Conventional elctric current flow is usually thought of as flowing from positive to negative, but at the quantum level; due to electrons having a negative charge; technically they really flow from negative to positive, and this is apparent in the cathode ray tube. Its the negatively charged electrons that glow in a cathode ray tube, and do so from the negative terminal, or cathode, hence the name.
"from anode to cathode". Normally, no. Taking a radio valve (electron tube), since the anode is positive compared to the cathode, and since electrons flow from surplus (at the negative cathode) to deficiency (at the positive anode), they do *not* flow from anode to cathode in normal operation. It's possible to have electrons striking the anode and *knocking off* electrons from it, and then to have those electrons travelling back towards the cathode. This is secondary emission. It was a problem in four-element "tetrode" valves in the early days, but has now been eliminated in practical designs. Long story short: it's possible, but undesirable and not common.
The Kuiper Belt is named after Gerard Kuiper; he was one of the only scientists who had theories about the Kuiper belt in the early fifties
While some of the basic concepts of social psychology were mentioned as early as Plato's time, social psychology as a modern discipline began in earnest after World War II. After the scope of the Holocaust was revealed, social scientists began studying the effects of conformity and obedience on social behavior.
