Rigorous Proof Based College Math - How to tackle?

I usually don't like to participate in these 'my-ego-so-big' version of 'yo-mama-so-fat' conversations but this one is too juicy to pass.

First, commando, yes writing proofs is very different than doing computational mathematics. Most people think they are good in Math because they can find answers to numerical problems. I thought that too, until I took a theoretical math class. I like to think of writing proofs as more closer to writing an argumentative essay. It's about being logical. Sometimes you might think you've proved something but it might be totally off.
Couple of things:
1. Know your basic proof techniques (i.e proof by contradiction, induction etc). Believe me they are used from the basic to some of the most advanced proofs.

2. You have to study other proofs in order to write ones on your own. See how your classmates write them. Ask your prof to help you reword or rewrite ones you think you've solved.

3. Remember that if you get stuck in the middle somewhere, sleep through the problem. Believe me when I say, I've had times when I got stuck in figuring out a proof and I would just stop. Then next day, it would just hit me, and walla. That means start your problem sets early!


Second, pire, you struck a chord there and I just had to bitch-slap back.
" I didn't want to waste my time writing code for
others, so moved to finance in which I learnt the maths including Ito
calculus, dynamic optimization, Game Theory, advance econometrics and
many more stuffs. While I took convex optimization class with
electrical engineering PhDs, I was ranked among top five in the class.
Compare the salary of PhDs in elec engineers/comp engineers, and those
of economics/finance, and you will see the difference. But more than
that, engineering only produces stupids like you (and perhaps Babu
Ram Bhattarai who claims he knows economics, eventhough he doesn't know jackshit."

I will dissect a sentence at a time. 'Many more stuffs?' Stuff is stuff. Why don't you take a language lesson before correcting someone else? So you think you are better than electrical engineers eh? Did you compare the salary of someone with a bachelors in EE vs. economics? Also, why is that all my engineer friends are employed and my econ friends had to go to grad school because they didn't get an offer?   And if you think salary is the only way to compare jobs, think again freakonomist. Did you take a look at cnnmoney's list of best jobs in America? Guess who got the number one spot? Oh Shit, it's Systems Engineers. How about that now?

Pire, let me quote your grandaddy as well.
"It seems to me what our nation needs is more civil engineers and electrical engineers and fewer financial engineers." That was Paul Volcker on PBS.

Now if you had stopped at that, I would probably not be writing this tirade but then you had to go on and say that engineering produces stupids. Damn, why did you have to do that? That's asking for trouble. Engineering produces stupids? So you are calling the people who built the empire state building, the automobile, the airplane, the computer, the internet, and also the software that you fu(king economists use to churn out numbers, stupid? It's true as they say, economists will never agree on anything. All they do is fu(king babble, and piss off engineers. :)
