Experimentalists: understood, say no more.

Theorists: ok, show me the Hamiltonian...including the noise terms.

Too real

Sources of error: psychosomatic popping noise interfered with measurements when viewing image

Nah... It's just that "usually calculations overestimate the experimental values".

Where was the experiment run? On a battlefield?

Setting up a bird listening device a few meters off an active runway and no filter for engine sounds.

Play back is of course volume tuned for the bird chirps when processing data

  • Hey boss, we have sincere troubles, SNR is off by too much.
  • how much?
  • 20dB
  • ah, then we're good, that's so ridiculous it's def. a gain problem in your measurement setup

The funny thing about RF work is how casually a few orders of magnitudes gets thrown around. 10 dB fudge factors for assorted losses are quite common.
