The last one sounds pretty hokey. All the others, without exception, sound to me like they're probably worth while, or at least courses matching those descriptions could well be.
Oh, and guess what? #7, the one that they quote as talking about "the natural numbers 1, 2, [and] 3", actually says this: "This course will explore the beauty and mystery of mathematics through a study of the patterns and properties of the natural numbers 1, 2, 3, ...." Apparently the author of the idiotic NYMag article is unable to distinguish between "1, 2, 3, and so on" and "1, 2, 3, and no others", even in a context where it's perfectly obvious which is meant. Obviously this is someone I should trust to tell me what mathematics courses are silly and "why Asia is winning".
