@AkivaWeinberger I don't understand what you are saying, but that seems like exactly the thing I'd like, some abstract definitions helping one to conceptually grasp the topic
Jul 14, 2017 17:02
@LeakyNun yes thats approach number 1 I outlined
Jul 14, 2017 16:58
one example. why does e^ix go in a circle? approach number 1: split the sum defining e in to halfs sin and cos respectively. approach number 2: take the derivative of e^ix, its ie^ix, i something turns it by 90 degrees, the slope always is the tangent of a circle!
Jul 14, 2017 16:57
its a discussion for me! I dont like formulas, but I think thats a stupid state of mind
Jul 14, 2017 16:52
@Daminark I think you have misunderstood me a little bit, to verify the correctness of a proof is the absolute minimum I would demand from myself. Its about feeling like I could have come up with them myself. to see the intuiton that binds together a group of theorems
Jul 14, 2017 16:49
@s.harp No! sorry
Jul 14, 2017 16:48
I want to understand and work on Information Theory for example
Jul 14, 2017 16:47
I want to do science!
Jul 14, 2017 16:45
But with formulas I'd think it would be enough to just think about them for a long time!
Jul 14, 2017 16:42
I am mostly interested in proving formulas I think
Jul 14, 2017 16:42
What do you mean by using?
Jul 14, 2017 16:41
@Semiclassical ok, a more practical question: how do I build up my skills with formulas the best? Just working through a hard book with lots of formulas in it?
Jul 14, 2017 16:38
do you manipulate formulas in your head or on paper? I do all the thinking in my head and write things down after that. however that doesn't really work with complicated formulas. but looking at them on paper doesnt seem to work for me either
Jul 14, 2017 16:36
@Semiclassical very good point
Jul 14, 2017 16:32
@Secret that answers why one should find them useful and beautiful. however do you actually think about the 'meaning' of every formula you come across or do you just work with them formally?
Jul 14, 2017 16:24
Eh, I have a stupid question. How do you enjoy formulas? I'm finishing my degree in computer science and I really enjoy the theoretical side of it. However with formulas I'm much worse than with worded reasoning and its holding me back.

I'm gonna go, continue writing my thesis
Apr 8, 2017 10:19
haha, no I don't think feynman would have needed such a course and he would have known
Apr 8, 2017 10:17
haha that sounds so weird. wouldn't want to be in such a course
Apr 8, 2017 10:17
but thats probably stupid. there have been people making things better always
Apr 8, 2017 10:16
haha
Apr 8, 2017 10:16
oh, no hope in school either
Apr 8, 2017 10:14
hmm. I never had much hope, some people ask, others dont. always thought it would be a thing of upbringing
Apr 8, 2017 10:10
I don't need experiments to tell me how much stupid stuff people believe. its painfully visible
Apr 8, 2017 10:05
is that a recursive trick
Apr 8, 2017 10:04
I'm surprised every day
Apr 8, 2017 10:02
yes makes more sense that way
Apr 8, 2017 10:01
I probably made it up somehow
Apr 8, 2017 10:00
yeah exactly
Apr 8, 2017 09:59
the situations seems really confusing en.wikipedia.org/wiki/G%C3%B6del%27s_ontological_proof
Apr 8, 2017 09:58
my mind makes up things
Apr 8, 2017 09:58
yeah I was meaning to say that he believed that a formal proof of the existence of god is silly. but I'm probably wrong
Apr 8, 2017 09:57
I'm trying to look it up now too.
Apr 8, 2017 09:55
thats not the opposite
Apr 8, 2017 09:55
@user21820 not 100% sure, better check it!
Apr 8, 2017 09:54
ah.
Apr 8, 2017 09:54
what is CH?
Apr 8, 2017 09:53
wikipedia says he did that for fun, to show how silly it is to do that
Apr 8, 2017 09:53
just didn't meet many people with interests in logic
Apr 8, 2017 09:52
I know
Apr 8, 2017 09:51
because these are the only people, I've met, wo opposed ZFC. these people brought god into it. it does not have anything to do with ZFC itself. just said that, because I wanted to make my emotional standing clear.
Apr 8, 2017 09:50
maybe life's just hard
Apr 8, 2017 09:50
again I know that
Apr 8, 2017 09:49
haha
Apr 8, 2017 09:49
lets wait for the next
Apr 8, 2017 09:48
just saying. ZFC seems ok, works so far. I'm fine
Apr 8, 2017 09:48
yeah sure
Apr 8, 2017 09:48
yeah I know, still thats my only emotional connection to it
Apr 8, 2017 09:46
never understood why one would toss the law of excluded middle
Apr 8, 2017 09:46
yeah and it seems ok to me. the others seem weird
