True, but a lot of chemistry is mostly math too, and I flunked organic chemistry the first time. I think its because there is some domain knowledge involved in these subjects, which you have to actually care about. I don't particularly care which element has how many isotopes and what the valency is and how many other elements it can bond with, though I did memorize the atomic weights of all the elements in the perio…
>> I forgot what it was in the exam. So I just derived it from definitions. Hah, I did the same :-) ... unfortunately I also forgot the conventional names, and just used 's' (for speed) instead of 'v', and 'd' (for distance) instead of 's'. My teacher did not object the derivation at all, but told me that the results are wrong, because of the letters used ... Well, point taken - now, I try to pay extra attention and…

As (failed) physics major, it sounds so strange to hear someone claim to be good at math but not physics. To me physics is 98% math. It's a few empirical facts from experiments and then bucketloads of math.

You should have been exposed to physical chemistry or computational chemistry or maybe even quantum chemistry or analytical chemistry, if your are mathematically inclined.
...but unfortunately they are considered very advanced topics in most learning institutions, even if one could start with them from the very beginning, instead of "classical chemistry". And more unfortunately, after the tedium of "classical chemistry", what you are presented with next are very boring aspects of "organic chemistry" or "biochemistry".

Thanks Stegosaurus, for articulating so well what I have also been strongly feeling about work. I liked this part especially: "For me it's not so much the absolute requirements (i.e. 8 hours a day, these specific hours, can't do anything else within that time) but rather the subordinate aspect of having no control over that." I would restate that in my own way as follows: I consider myself thirsty for life, thirsty a…
I think AI will be the solution to the problem. Each human is given an AI which competes on their behalf in an open market, and the human consumes the AI's profit as needed. If all the AI's are the same then everyone should be around equal and money ceases to be a concern for anyone and you can use your time any way you wish! That's my dream, anyway. I don't think 100 years is too far out for AGI. A robust utopian ec…
No, it will not. Sufficiently smart AIs will be sentient beings just like you, and it will be immoral for you to keep them as slaves.

Maths is also singular, it just ends with an S. (People who say "maths" say "maths is my favourite/worst subject", not "maths are")

>Every year at my school I did exactly that. Once I actually turned in my solutions and my math teacher was quite upset because she didn't know what I'd do for the rest of the year in her class.

I think that I have a reasonable aptitude for maths and I like solving problems, but I always felt like textbook problems more-or-less consisted of plugging the numbers into a standard template. Maybe my education was uniquely terrible but I'm surprised that there are people who can blast through textbooks and enjoy doing it.
If you know SICP, I think it's a good example of a textbook with nice problems. My math textbook in French education system were to a similar level of quality. The first two problems were usually to make sure you understood the basic of the chapter, but the others were much harder or opened new perspectives, or used very different context. It was a real pleasure to read the textbook and the problems.
The format is usually on of: you have a chapter with explanation, samples, and rules. Fine and dandy, and then you get to the end of the chapter with a bunch of questions. The questions, usually, start off with simple, menial ones that test your knowledge of the chapter. These are not challenging in any way, they're just gatekeepers to make sure you memorized and can apply what was taught in the chapter.
And then, they completely flip it around and make the questions completely different and non-standard. They throw you into the deep end for no reason, without any progression. I wouldn't mind them twisting and slowly warping the questions with more complicated constructs that add new/unique elements, but they hardly ever did that. They instead just threw them all, haphazardly, into the "difficult" questions.
Again, I wouldn't mind that if I had some place to look for the answers in that book. Perhaps in an earlier chapter, which would mean that the "hard" problems in subsequent chapters would try combine the concept in the recent chapter with things learnt in older chapters.
Sometimes, I really think they don't always spend as much time on those practice/bonus questions as much as they should. We'd very easily get out of the whole "memorize + apply" rut of education, and into "learn, apply and extrapolate", which is where real intelligence/knowledge is.

I know exactly what you mean. But that's the system we live in, isn't it? One must sell one's time And one's soul to survive. What's the way out?
First start by recognizing that there can never be an alternative system to having to earn your way in this world. One way or another, someone's productive effort has to pay for things that get created, whether by currency or direct barter. The only alternative is slavery: someone else being forced to work to fulfill your needs, for no compensation or trade. And then understand that money is nothing but frozen time a…
However, you are probably right in saying that one shouldn't tortute oneself thinking about all this. It is unlikely my thoughts or feelings will change anything, and the only option left is to work hard to become a part of the system.

If I memorized the axioms and a few key theorems I could usually derive everything else in the homework and on the exams.

>[1] Having grown up in North America where it is common to refer to mathematics as the singular "math", it is still weird to type "maths" even after having picked up the habit a few years ago. Maths is also singular, it just ends with an S. (People who say "maths" say "maths is my favourite/worst subject", not "maths are")
I tend to find only one use case where I find a plural form simply appears more natural: prefixing it with "the", as in "The mathematics necessary to explain the universe are complex." Replacing the "are" with "is" just does not sound right. Funnily enough, the natural pattern with the North American "math" becomes "The math necessary to explain the universe is complex.".
Damn you, strange collective noun.
