Valentine Bargmann studied the central extension of an algebra named for this physicist that characterizes symmetries of the Schrödinger equation. Taking the limit as c tends to infinity in the Poincaré group produces a 10-dimensional (15[1])group named for this physicist (-5[2])containing namesake “transformations” mapping “x” to “x minus v t.” It’s not Einstein, (15[1])but this physicist (15[1])deduced a principle of equivalence of inertial (-5[1])reference frames in (15[1])(*) relativity with a thought experiment involving the detection of motion on a smoothly sailing ship. (10[2])This physicist reportedly demonstrated the invariance of gravitational acceleration by dropping balls of differing masses from the Leaning (10[1])Tower of Pisa. (10[1])For 10 (10[1])points, name this early physicist and astronomer whose espousal of Copernicanism led to his censure by the Catholic church. ■END■
