It doesnt matter how beautiful your theory is, it doesnt matter how smart you
are. If it doesnt agree with experiment, its wrong.
Richard Feynman (1918-1988)
To observe free and driven oscillations of an RLC circuit.
Uncertainty and Significant Figures
"Errors using inadequate data are much less than those using no data at all."
The results of any physical measurement process will be inaccurate to a greater or lesser
degree. We will frequently want to know
Deflection of Electrons
