Has anybody said coffee/Red Bull yet?

http://www.motorcycle-usa.com/2013/03/article/backmarker-breaking-down-the-bubba-scrub/ I know this may be old, but this also looks at some more physics behind the scrubbing. There seems to be a lot of physics going on in SuperCross, next you should look at the physics behind MotoGP Racers...

Yes, my understanding was that it was like a spectrometer but wasn't sure what the advantage was. I thought we were going to be looking at the diffraction grating, but you are correct. It's the Auger electrons we'll be looking at. I was looking more for a deeper understanding than conceptual on...

I'm supposed to be working with a CMA (Cylindrical Mirror Analyzer), but I'm more interested in the physics behind it. This is the instrument in question that we are looking to get: http://www.rbdinstruments.com/products/micro-cma.html We want it to look at different eV levels of different...

Interesting, I've never worked with a Lego Mindstorm, so each different color was able to be given a new function? And how did you account for turning? Did you slow down one of the motors? Or just turn it off? I always wanted to play around with a mindstorm when I was younger, but could never...

Yeah I found a really good one on there that really helped me out thanks! http://www.instructables.com/id/A-Simple-Arduino-Based-Line-Follower/

I'm looking to build an Arduino that is capable of following a line depending on a colored strip on the ground, either black or white. I think I might use a LDR, but not quite sure where to even start to be honest. My office is having an Arduino contest, and I just want the Arduino to carry...

Do you have a recommendation of any other mathematical methods books that would be a bit easier to comprehend? I feel myself getting lost in the jumps boas does from explaining the basic concepts to jumping straight to certain complex ideas with little explanation.

When you say sphere, do you mean a 3D sphere, or a 2D circle that lives on a plane. You can define the sphere itself as a plane, and in calc 3 you learn that you can define shapes and do "pull backs" or "push forwards" in which you can stretch an object/shape/line and make it one to one to a...

Is there any alternative books that teach you how to just do the problems rather than emphasizing why, and is there any books that emphasize why in an easier format? Something like a "mathematical methods for dummies" book? This is the book I'm referring to (...

I believe that with the use of Green's theorem and some other integration techniques, you will need to look at techniques from Calc 3 and at least gone through Calc 1 and Calc 2. I know you posted this long time ago, but perhaps a member reading this will have the same question. Cheers!

I think you are thinking of it in reverse. You need things like linear algebra, planes, lines, etc. to define geometric shapes, not the other way around. Have you taken a multivariable course? Or have you heard of the idea of domains and sets of values living in a "neighborhood" of another...

Oh okay, this clarified it for me, redid the problem and got it correctly, thank you! :woot:

So just take the volume integral with the density formula and that will account for the change in density. But why is there no jacobian if we are changing coordinate systems we must account for this somehow...

so triple integral from the bounds being the same as if i was finding half a sphere (obviously) times the Jacobian integrated with the density function in terms of spherical coordinates. That would be this equations ∫∫FoΦ(u,v)||Tu,Tv||dudv as this part ∫∫FoΦ(u,v)(((((||Tu,Tv||)))))dudv is the...
