I see your point and this is what I have more or less been repeatedly told.I think like you told,the best thing to do would be to condense a lot of courses down to their key concepts that can be kept refreshed through spaced repetition.
I think 90% may be an underestimate(you could probably tell me more about it).Like, over the course of your career,you would have used less than 10% of the info you collected through your college(including all the nitty-gritties of various topics-the derivations,the special cases etc..).These contribute immensely to your understanding of the topic,but my question is do the nitty-gritties stay after a long time? This is my main question.... (read more)
Thanks. That's a really nice list.I have not seen a lot of these ideas previously.Especially general purpose tool-idea and stock of problems-idea is very good.These ideas are really nice to ensure in-built spaced repetition.
But can you give me some ideas about the second question I asked.I cant do this because I am still undergrad.So pick a topic that you learned about say 4-5 years ago(or any time-frame for that matter),make sure that you haven't used that particular knowledge for the past 4-5 years,try to get back to the same knowledge-level that you had acquired when you first learned the topic(or some % of it) and measure the amount of effort/time that you took.Then calculate the ratio of (this time or effort)/(time or effort when you first read that particular topic).
Hey,nice to meet a Mechanical engineer here.I have heard this told to me a lot.But I think as John has pointed out,education is mostly used as a signalling device.From what I understand,even if you were to were do a post-grad in Mechanical and work in research field,you would still NOT be using 90% of your education.If you ask that is a huge waste of time.Contrary to John,if you take a Mechanical Engineering degree,you will mostly end up studying/reading a lot of stuff that you surely know that you will not use in the future.We have to finish some specific courses to complete our degree requirements..
I think you are overestimating the time you... (read more)
So a bit of background about me before I go into the question.So I am sophomore studying Mechanical Engineering in India.
I have noticed that I have forgotten about 80-90% of the course-work that I did during the first year.Don't get me wrong,I studied the courses properly and not for the test.Still,if you were to ask me how much of the course I remember now, I would at the very best remember the general idea of the stuff I read.
This is very startling from a long time perspective.College-work in India is generally more overloaded than other countries(from what I have observed),so what this means is people consume a lot of knowledge in... (read 487 more words →)
I dont get it.Any belief could be said to "pay rent" if you can conceive a situation where it will be useful later on.
A general situation that I made up was.
Given any belief X and at least 2 people believe X,I always have utility in believing X(I think it should be knowing) as it helps me predict the actions of the other 2 people that believe in X.
Even in the example where the student regurgitates it onto the upcoming quiz-the belief had utility for him as he could use that to improve his grades(constraining reality in a way he wants it to be).
I believe you should judge your beliefs based on expected utility in the future(extremely hard to calculate).
PS:This is my first comment/post.Forgive me if is a bit rough
Hi guys,been a long time lurker here.Wanted to ask this,have you guys ever done rereads for the Sequences so that new guys can engage with he content better and discuss..Just a thought
