How about, instead of begging for what will be probably the most pointless debate on HN this whole week with innuendo, you put in a show of good faith with that question and find a credible source that suggests that a German high school diploma is equivalent to an American college degree?
Perhaps after you do that, it'll be a good idea for anyone to dignify that question.
for the physics degree at Arizona state. It doesn’t seem to have a bachelor thesis or comparable work, it has about 50% stuff which has nothing whatsoever to do with physics (e.g. “Humanities, Fine Arts and Design (HU) AND Historical Awareness (H)”) and its physics courses seem end with things like “PHY 302: Mathematical Methods in Physics II“, which contains “complex variables”, “PHY 311: Classical Particles, Fields, and Matter II“, with “Faraday’s Law” and just a single QM course “PHY 314: Quantum Physics I” which only mentions wave mechanics, but makes no mention of perturbation theory, matrix mechanics or the standard Hilbert space approach with Dirac notation.
Especially the 50%-or-so of liberal arts, historical awareness etc. seem to be more appropriately placed in a high school degree than in a college degree, and things like complex variables shouldn’t require introduction in term five either.
The system in the US is different. You can get credits in various topics despite being enrolled in, say, Physics. In Germany, you're enrolled in one subject and have mostly predefined classes for that subject until you have something like a pre-diploma. This doesn't tell you anything about the depth of a class.
I studied for a year at ASU (computer science) and found there's not much difference between low-level courses and pre-diploma courses in Germany. A master's dregree in the US is more or less comparable to a diploma.
Also: Do you compare the former 13 years of school in Germany or the new 12-year period of school with the American education system?
Perhaps after you do that, it'll be a good idea for anyone to dignify that question.
