I meant worst as in "why would that be an indeterminate form?"

The answer, obviously is because the log is indeterminate. ln(1^inf)=inf*ln(1)=inf*0.

I think he has a very large misunderstanding of virtual particles.

### Re: Travling the Speed of light with a light

And to keep that statement from unravelling the laws of relativity, you can never travel through that material at the new speed of light, c n . No. See http://en.wikipedia.org/wiki/Cherenkov_radiation for a start. Interesting fact: In the early days of particle accelerators, physicists would put th...

### Re: Help me think up crazy hard SF technology ideas

The methods we'll have used however, are complete speculation. If we are still using chemical (or nuclear) rockets, we cannot do interstellar travel. Things are just too far away, espically habitable planets. For those ships traveling at significant percentages of c (even as low as 1%), a tiny bit ...

### Re: Tricky Multivariable Limits

try approaching on the line y=x*parameter. This will let you see if it converges in all directions. It must converge for all values of the paramter.

### Re: Help me think up crazy hard SF technology ideas

Hmm. -Zero-time communication and travel. We know now that it's theoretically possible for quantum particles to transfer information to each other instantly, but we can't use it for any feasible application. However, extrapolating this knowledge provides instant-transport and communication devices ...

When I was in calc, the worst indeterminate form was 1^infinity.

Quintopia my Galois theory prof told us a wonderful story. He named the student too, but I couldn't remember. Student walks into class late, sees a few problems on the board, takes them down as homework. Shows up at the prof's office the next week and says, sorry sir, but I could only solve one of ...

I use the 3 dots in a triangle. Does nobody else use it? That generally (and by "generally", I mean, "it does") means 'Therefore'. Yeah but maybe he uses it just before the final line. We're not talking about what you use before the final line. We're talking about the symbold at...
