Opinions on the use of the expression "Quantum Leap"... It is an oxymoron, right? Quantum leap is the the physical distance moved by an electron when changing energy levels, correct? If you are making "quantum leaps" in technological developments, wouldn't you be going absolutely nowhere? I've even seen this term used in physics papers! For instance, in a paper about Arrayed Waveguide Gratings/DWDM (basically some telecom photonics) that I have in front of me, "This provides a quantum increase in network capacity without the need to laying new lines." I just think it is funny that a term that is so wrong is used even by technical people who probably know that it is incorrect.
