Two Degrees of Freedom
Normal Modes of Vibration
A pendulum’s operation’s chaotic. A body hangs from a fixed point, pendant; her earrings as she steps back, following, following during the dance as she spins, draws out, pulls; the necklace pendant between her breasts, not freely under combined forces regulating movement. See oscillation, swing. See electricity, current, spark. See the motion of the moon so like the sun’s shaking formerly. In the Museum of Science and Industry, the giant pendulum ticks ivory dominoes, ebony dominos encircling its path over the floor: forget butterflies, forget stocks. We’ve astrology. The clock underestimates time: bob, wheel, pearl, river. her Forced Modes Alternating voltage, turning movement or gait; she moves sideways about the center or lead, leaps, avoids a thrust. See electromotive, charge, action, rolling, roiling, turning about; she rolls, tests and turns, and changes, changes her mind, clothes, approach, changeable, winsome, fetching, twined, her rings, bracelets, bangles, baubles, belts like vines. Warm up band width. Unless initial conditions interest, complex impudence substitutes, substituting harmonic forms. Don’t hold back. |  |
