An example of outcome-based journalism, I guess.
"Physicist" has already, and thankfully, spared my from trying to explain what the author really meant. Funny, isn't it, that his "explanations" are invariably more succinct and precise than the original "quote" that he is explaining.
Now, if I only knew what a "Compton wavelength" is, I'd be all set .... I guess looking that up is a reasonable exercise for the student.
How are the Compton and de Broglie wavelengths related?
Day one of quantum class from hell: "The wavefunction contains all knowable information about the system. Extracting it is an exercise left to the student. Good day."
