Every fall we do an experiment in the undergrad lab class where we demonstrate superplasticity. This is done using a lead-tin alloy containing 62% tin. Last year we discovered that our alloy really is only 45% tin.
Doing the math today, the correction requires me to add one pound of new tin for every kilogram of existing alloy.
I'm not going to ask NASA for help, as I don't want to confuse the units issue any more than necessary.
In other news, I'm currently trying to use Ghost v14 to clone teaching lab computers. It's slow, as it's all going through the USB port on my office computer.
