Also got into the NUF, I'll be spending the summer doing a theory project at Princeton.

Two applications, PPPL NUF (top choice) and SULI (PPPL and Los Alamos). Really want to do plasma, and my research group has some collaborators at PPPL, so I could start a project there and continue it during the school year (if necessary). Crossing my fingers! (Haven't heard anything yet >.>)

Ah, well done. Thanks.

I disagree. This would be analogous to a volume of revolution--rather, we are taking a surface area. Each disk has radius r and therefore circumference 2*pi*r; since r varies as a function of h, we can evaluate the integral of 2*pi*r*dh from 0 to 4.

Surface area of a cone--inconsistency? Geometry tells us that the surface area of a cone with a circular base is SA = \pi rs where s is the slant height of the cone, or SA = \pi r \sqrt{r^2 + h^2} Take a cone with a circular base of radius 1 and a height of 4. This formula tells us...
