At his Forbes blog, Chad Orzel wrote the essay
Orzel starts by saying that there are people who find it natural to bring the undergraduate freshmen as quickly as they can near the cutting edge of physics – to modern physics that includes relativity and quantum mechanics – once they get into the college. People don't want the well-known 19th century stuff and the nontrivial new things that the laymen usually don't know make the university a cooler place.
In the past, some of us were defending some exposure of students of high schools if not basic schools to quantum mechanics, too.
However, when this strategy is applied, he argues, one usually ends up with lots of students who just don't understand why some idea – like the wave-particle duality – was introduced at all. Like other instructors, Orzel often answers "Because I say so" when he is asked some "Why" questions. The pedagogic procedures often rely on references to the authorities which is counterproductive and unscientific in spirit.
