This scientist is the first alphabetical namesake of a dispersion formula that calculates the cross-section for a photon scattering by an atomic electron. With Euler, this scientist is the namesake of a Lagrangian that describes photon-photon scattering in QED. Coherent states that saturate one of this scientist’s namesake statements (-5[1])are “squeezed.” (15[4])State vectors are (15[1])(*) time-independent, (10[1])while operators evolve over time (10[1])in this scientist’s namesake “picture” (10[1])of quantum mechanics. (10[1])Sigma sub p times (10[1])sigma sub x is greater than (10[3])or equal to h-bar over (10[2])2 (10[3])according (10[2])to this scientist’s (10[1])namesake (10[1])statement, (10[1])which states that position and momentum cannot be (10[1])simultaneously (10[1])known. (10[1])For 10 points, name this German scientist, who formulated a namesake uncertainty principle. ■END■ (10[1])
