The National Mag Lab: The World's Strongest Magnet.

The video shows the 21 Tesla Magnet, the highest field magnet in the world. (The ion source seems surprisingly generic, but hey, at that field strength, who cares?)

1. Another cool video. The idea that the lab is open to researchers or engineers who may....

....not have expertise with magnets but have an experiment that they have designed and want to test is also very cool. One odd question, do you know what the tattoo on her back is about?

2. It's a differential equation

Not sure what for, though. Given her enthusiasm, it's probably something to do with Maxwell!

3. It's just a set of symbols indicating a second derivative. In principle, could be anything.

But 'x' is usually taken to be a space coordinate and 't' to represent time, so the second derivative w/respect to time would be acceleration. Not clear to me why she chose that.

5. Probably because she wanted to be thought of as accelerating, or because she was just...

...a kid when she got it, maybe as an undergraduate.

This mass spec is probably set up as an FTICR, and there probably more relevant equations she could have chosen, and if she wanted a second derivative, she could have chosen a wave equation.

4. Also, no vacuum cleaners allowed.

Trust me, it's a good rule.
