lol so true.

[Chun Liroy]

Oh damn, my bad FB didnt even tell me I had anything.

Also, your wife gave up the goods. I might be spamming you with texts some time.

[Mizango]

Yeah she told me lol

[Woozie]

The other grad students were pissed when they found out I was going to be in their real analysis class back in August. I had already Melvin'd Advanced Calc I and II. I also Melvin'd advanced linear algebra this semester, but the teacher gave them a curve despite my 100%, so I don't think anyone is mad at me. Abstract Algebra II is the first time I ever got Melvin'd by someone else in a math class. These two grad students there live and breathe algebra. Both of them are writing their thesis on Algebra, are taking a special topics class on character theory, and one of them took a topics in group theory class last year too (sylow's theorem and the classification of simple groups). I, on the other hand, hate algebra (analysis ftw), am writing my thesis on analysis, and only took last years Topics in Algebra because Abstract II was canceled and I needed another class, and plus the professor promised there would be an intro to Lie groups and representations if I took the class (he needed another student so that the department would let him run the class, and he knew that Lie groups and representations is the best way to lure a physicists into an algebra class, though we didn't cover them as much as I wanted).

[Mizango]

lol Woozie. You're lucky they didnt petition to keep you out or tie you down to prevent you from showing up lol.

So I have a legitimate question. Why do text books number examples/figures/equations as 10.1 10.2 10.3..... 10.10 10.11. Do they not realize it is essentially, equivalent?

[Woozie]

Why wouldn't they number them like that? It's easier to keep track of theorems and stuff when you can just say "by thm 10.3", etc.

[Eliseos]

Yeah, especially in later chapters its much easier to tell 8.3 and where its located than it is from equation xyz in some random chapter that you have to look up.

[Tekki]

been in one of these for electrical engineering. 75% of the class fail and he was made to rewrite his course work. He made the simplest parts of Digital EE look like rocket science... boring boring rocket science.

Well I'm talking about 10.1 vs 10.10

[Woozie]

Well, those aren't decimal numbers (where 10.1 and 10.10 would be the same number. The numbers after the "decimal point" are natural numbers. So those aren't the same any more than 1 and 10 are the same.

[Chun Liroy]

I know, I'm splitting hairs and being stupid. But I often say them as "ten point two" so logically, "ten point ten" is awkward to me do you at least understand my plight?!

[Cantih]

Not mathy or physicsy, but I am excite that LA will be getting one of the space shuttles.
Having it in Expo Park, with the new light rail line on that street finally opening later this year, will be handy.

That's a good question. Lesser sciences like biology and chemistry could get away with 16 numbers to cover everything in the book, but when you have 100-200 equations per chapters, using two number make it much easier for reference purpose.

Like this:

Spoiler: show

[Chun Liroy]

Holy hell.

[Eliseos]

That isn't even the end of the chapter lol. That chapter goes up to equation 9.204.

Edit: This is also the subject that uses every single fucking letter of the alphabet for some variable/field. Doesn't even include all of the greek letters for variables.

[Shiroikage]

Are you mentally deficient?

That reminds me of a game we played in physics class once to come up with a meaning for every letter of the alphabet. Something that most people will recognize because the symbol is standard or often used. For example, A is the vector potential, B is the magnetic field, C is the speed of light, D is the electric displacement field, e is the identity in group theory, or the standard basis symbols in linear algebra/physics, etc. Miz, you should have taught your daughter her ABC's that way.

That chapter you posted...the horror. It was around that part I started hating EM.

I think fluid dynamics had it worse with variable though. There was just so many. QM is about as bad too, especially when you works in parallel with mathematics (set theories and the like).

lol...

Be careful though, you don't want your kid to end up reading relativity book when they are 4 year old...you don't know how it can end.

[edit]
And going through your alphabet (and greek one!) is really nice memory games...I think anyone in physics should do it occasionally. Or they should if they have memories issue like me
