What's All This Femtoampere Stuff, Anyhow?
Why people recommend it
A deep look at measuring femtoampere level op amp bias and leakage currents, which accidentally turned into a cosmic ray detector, cited for ultra low current design.
Watch for: Advanced; suits anyone chasing tiny leakage currents
In their words
Here's a youtube of Bob in action, 27:15 is where he's talking about the cosmic rays.
