    Programs Getting a degree: speed or grades?

    Thanks for the answers. Well to explain and clarify some more, the situation is that what i have time to do, i do quite well. I'm in france, so the system is different, but I'm guessing I'm getting A's or B+'s for that. However, i don't have time to do everything, so I'm guessing i'll finish the...

    Programs Getting a degree: speed or grades?

    Well to give some background info, I'm 25 and currently doing my first undergraduate year in physics. I'm unemployed at the moment, but was working until december and expect to get a new job soon, and that plus me having to relearn lots of high school stuff has led me to expect that...

    Schools What Are the Best Books for Learning Basic Physics with No Prior Knowledge?

    http://www.khanacademy.org/ For me, the best possible ressource for an intro to high school physics and maths. Not a book though, rather a collection of tutorial videos and assorted exercises, but to me this makes it much more interesting.

    Chemistry, physics and math self-teaching

    From my experience, although you can go far by learning everything by yourself if you have great discipline, you'll never get as far and as efficiently as you could by learning and at the same time discussing with other intelligent and passionate people, and it's probably going to be less fun...

    Undergrad What's the difference between complex numbers and vectors?

    Thanks for all the answers! This is quite fascinating, i had the feeling that the linear algebra i did was kinda opening the way for a much more generalized and abstract approach to numbers, that could shed a new light on many other topics, but i haven't gone to that point yet. I am also...

    Undergrad Is Learning Detailed Math Still Necessary in the Age of Computers?

    I think that we are thinking too generally: some things in maths should be learned by hand, some things would immensely benefit from mathematica-like software. The good question is what topic falls in what category, and for whom. People studying maths in uni, for example, need to really learn...

    High School Favorite Equation: Quadratic Formula - Solving for X

    For all of you talking about Euler's formula, i'd recommend looking at: http://betterexplained.com/articles/intuitive-understanding-of-eulers-formula/ Which gives what to me is a very good explanation, kinda breaks the wonder in a way but deepens the understanding. I don't have a...

    Undergrad What's the difference between complex numbers and vectors?

    Well it's all in the title: i don't understand why we define vectors and complex numbers differently, with different properties (eg vector dot product and cross product and complex multiplication). After all, all a complex number is is a 2-uplet of real numbers, but that's exactly the same as a...

    Undergrad Is Learning Detailed Math Still Necessary in the Age of Computers?

    Great video Amanheis, thanks! That's exactly what i was thinking about!

    Undergrad Is Learning Detailed Math Still Necessary in the Age of Computers?

    Well I'm pretty much convinced! Some very good arguments here, thanks for the replies. I think the crux of the problem is that integration is a very complex thing to do, not like, i don't know, calculating the fraction of two real numbers. I was convinced the first time someone said that...

    Undergrad Is Learning Detailed Math Still Necessary in the Age of Computers?

    Humans can harvest grain by hand perfectly well, should we stop having machines do that for us?:-p More seriously, you misunderstand me: i never said one should not learn integration, i explicitly said i fully support learning what an integral is, I'm merely asking why one learns it in such...

    Undergrad Is Learning Detailed Math Still Necessary in the Age of Computers?

    Well I've just installed Mathematica on my laptop, and have been playing with it for a while. And this made me realize one thing: lots and lots of things that we learn in math lectures can be done very easily with a computer! derivation, integration, and probably much much more... This has...

    Asking for Ye ole Guidance and Opinion

    Two words for you: Khan Academy. I know you said you wanted a real book and not an online ressource, but i'd still advise you to look at the website, I've found it great for a not scary introduction to maths.

    How to retain information (long-term)

    My personal approach is to memorize as few things as possible, and to focus on understanding the concepts and being able to rederive most things each time you use them. Basic example for calculus, there's a rule for differentiation of products and one for differentiation of quotients, i just...

    Programs A few questions about PHD in the UK

    Wow, many thanks for the number and quality of the answers. And it's mostly good news too:-).
