Why This Stuff Costs $2700 Trillion Per Gram - Antimatter at CERN

A friend of mine is an operator at FNAL. He loaded the wrong file once, and lost/destroyed several days worth of antiprotons they'd been creating/saving for a run. (measured as beam current, he watched the antiproton ring's beam current graph plummeting.) He had a lot of angry scientists to apologize to that morning.
