Very Large Telescope

The Very Large Telescope (VLT) is a telescope operated by the European Southern Observatory on Cerro Paranal in the Atacama Desert of northern Chile. The VLT consists of four individual telescopes, each with a primary mirror 8.2 m across, which are generally used separately but can be used together to achieve very high angular resolution. The four separate optical telescopes are known as Antu, Kueyen, Melipal and Yepun, which are all words for astronomical objects in the Mapuche language. The telescopes form an array which is complemented by four movable Auxiliary Telescopes (ATs) of 1.8 m aperture...

$Mathematics$ Differential Geometry

Discussions about differential geometry in an informal spirit

I'm sure everyone here is familiar with the book "Elementary Differential Geometry" by Barrett O'Neill. I'm currently taking an introductory course in diff geo, and although I seem to grasp it, I can't seem to replicate anything, especially problems in the textbook. As such, I was wondering if their was a solution manual out there to help out.

@PlasmaHH That was actually a great analogy. Thanks for that piece of wisdom

Jon Snow

Oct 6, 2015 07:43

Or was it just more advanced education? i.e. Master's/PHD

Jon Snow

Oct 6, 2015 07:42

Quick question, all. Do you gain most of your EE knowledge through a bachelor's degree, or through experience? I feel like I'm not going to be learning shit compared to what's going on in this chatbox.

I received it

Sorry I'll be back in a minute

Yes

Give me a moment to check what my username is

Jon Snow

I'm currently in a special relativity course

Jon Snow

Oct 6, 2015 07:12

I do have skype, but I don't use that too often

Jon Snow

Oct 6, 2015 07:12

Yes, it's sad, the more I find out, the more I realize I have to learn :(

Jon Snow

Oct 6, 2015 07:12

Haha, me too

Jon Snow

Oct 6, 2015 07:11

Unfortunately, I'm a complete newbie to this stuff. My knowledge extends only to the fact that general relativity is based on differential geometry, so I decided to begin studying it

Jon Snow

Oct 6, 2015 07:10

Sure, thanks

Is that unnecessary?

Jon Snow

Oct 6, 2015 07:07

My reason for getting the book isn't for a course, though, it's to gain a better understanding before learning differential geometry

Jon Snow

Oct 6, 2015 07:06

Do you still enroll in the classes though?

Jon Snow

Oct 6, 2015 07:05

I'm an engineering/physics major, so I don't have time to enroll in these classes

Oct 6, 2015 07:04

It seems like Mendelson's book would be a better one for self-study in my opnion

Jon Snow

Oct 6, 2015 07:00

How do you keep track so effectively? :O

Jon Snow

Oct 6, 2015 06:58

@AlecTeal, what do they mean by pre, norm, and post?

Jon Snow

Oct 6, 2015 06:57

Have fun

Jon Snow

Oct 6, 2015 06:57

I have the by Farlow "Partial Differential Equations for Scientists and Engineers".

Jon Snow

Oct 6, 2015 06:55

Haha, thanks guys. @Huy you mentioned earlier "Topology for functional analysis and differential geometry". Would it be a big difference if I get a book that doesn't particularly focus on those two topics?
Also, @AlecTeal, My PDE book is by Dover, and it cost $10. It's actually an amazing book for the price.

Jon Snow

Oct 6, 2015 06:49

@AlecTeal, true, but I was wondering if anyone had a personal recommendations

Jon Snow

Oct 6, 2015 06:48

I see, I'll take a look at that. @Ale

Jon Snow

Oct 6, 2015 06:46

Ahh. Do you know any books that are useful for functional analysis?

Jon Snow

Oct 6, 2015 06:44

What I covered in multivariable calc was things like multiple integration and its applications, flux, green's theorem and whatnot. I don't think I actually learned much vector calculus

Jon Snow

Oct 6, 2015 06:41

Hmm, I've taken a course in linear and abstract algebra, but I'm pretty sure we only scratched the surface. Are those related to vector calculus? And no, I don't know any topology

Jon Snow

Oct 6, 2015 06:38

I've heard of functional analysis, but what is that? And what about operator algebra, I've never heard of that?

Jon Snow

Oct 6, 2015 06:35

Thank you. My current goal is to learn differential geometry to begin studying general relativity. I've heard that you need to know differential equations to learn differential geometry, and I have taken a course in ODE. I recently bought a book in PDE to learn, so I can also learn quantum mechanics. I've taken up to multivariable calculus, but I want to know, what else would be required for me to learn differential geometry, other than differential equations

Jon Snow

Oct 6, 2015 06:30

I want to learn differential geometry, and I had a few questions, if you guys have the time :D

Jon Snow

Oct 6, 2015 06:29

Jon Snow

Oct 6, 2015 06:28

None at all

Jon Snow

Oct 6, 2015 06:27

Do you happen to know about differential geometry?

Jon Snow

Oct 6, 2015 06:27

Yay :D

Jon Snow

Oct 6, 2015 06:24

Anyone here?
