Interesting to see how strongly nuclear
everyone gets when gas is over $3.00

I wonder if anyone noticed how difficult it
is to mine uranium. There is a pretty
good study about this, which indicates that
if the world went 100% nuclear energy, the
fuel would be exhausted in just a few years.

Interestingly, I can't find much about this
in more recent studies which mostly seem to
written by industry boosters.

Feinman goes into some detail about
his work on mechanical balistic computers
in "Surely you're joking, Mr. Feinman"

It's a height transfer gauge.
Transfer gauges are used to transfer
a measurement from a pattern to a workpiece,
or from an item being measured to a ruler.
