Well, the basic idea is that if the most difficult problems are non-scientific and always have been, then I'm not sure that scientists have a right to say their problems are hard - at least not with the implication that other problems are easier.
Regarding college, that seems to be a different thing. I guess you consider the non-science and non-engineering courses easier, because they don't address the what you call the vast majority if the most difficult problems?
As an aside, regarding evidence that science and engineering are hard - couldn't the courses be harder in college because instruction is poorer?
No, I think engineering and science are fundamentally hard because they require that a large amount of knowledge and experience be brought to bear to whatever problem is at hand. I feel like you're wordsmithing a bit here and focusing on word definitions rather than the big picture. What is a hard problem? Solving our economic crises seems impossible. Finding an end to war or a way for the people of the world to be free of hunger are incredibly hard problems that won't be solved by science.
But... that said, when most people say "subject X is hard" they aren't talking about grandiose, pie in the sky problems. They are talking about either: 1. the challenges inherent in making progress in the field, 2. the difficulty in acquiring the knowledge and skills needed to be a competent practitioner of the field, or 3. The difficultly in solving (or even grasping) salient problems before them.
Take, for example, the Apollo moon landing. It was one of the hardest projects ever undertaken and completed successfully. Yet, virtually all the techniques used to get there were techniques that were known and only in a few places (use of integrated circuits, rendevous in space, etc) was there truly something "new". But the devil's in the details and that is what science and engineering are all about: thinking creatively, carefully, and in a disciplined manner in order to meet your objectives. It's really hard to hand-wave and "wing it" in science and engineering.
I think the instruction in engineering vs other courses is roughly similar. I've got a little game for you. Pick an area of history you know little about (for example the social history of medieval Spain). Also pick an area of science or engineering you know little about. For example, if you're an EE, pick something like x-ray diffraction study of crystals and their properties. Now, study each field for a week. Do you think you'll acquire more of the body of knowledge of one field compared to another in a week? Does this say something about if History or Science/Engineering are fundamentally hard?
In college I took a lot of math, science, and engineering classes. I also took lot of music, history, and philosophy classes. The engineering and science classes required virtually constant studying, problem sets, labs, and even going through other books trying to figure out what was going on. In grad school it was worse.
To get the same grades in music or history class, for example, I would only have to cram a paper writing session into a couple of weekends and study 4 to 10 hours for the final. Much easier. Why do you think non-engineering or science students have so much more fun in college?
