Saved the point at the last second and used D.Va's ult to kill three, punched Mercy dead.

Finished the game with a D.Va/Zarya ult combo on Gibraltar.

Game winning ult by Mercy.

Just a fun moment when I managed to catch the enemy team unaware and really rip them apart.

One super, four kills.

Pendula coupled together with springs and damped by friction can exhibit interesting behavior together. A series of such pendula strung together can create a transmission line. Here the pendulum on the far left is given a kick. The rest of the pendula follow suit, flipping over just once and then slowly returning to equilibrium. Too much friction and the pendula won't flip over, too little and they undergo multiple revolutions. When the "flip" reaches the end of the line it reflects back and travels right to left again, leaving the pendula of the system in a disordered state. Proper friction on the last pendulum would prevent this. This is entirely analogous to electromagnetic waves propagating in a wire with improper termination.

The underdamped pendulum presents an interesting case of dynamics. When provided sufficient torque of T > m g l it will begin doing full revolutions around the center. Because the amount of friction is insufficient to stop it immediately, an amount of torque T < m g l will keep the pendulum undergoing the same basic behavior, though at a reduced speed. This video shows a pendulum on the top and the torque applied as a function of time in the bottom. Units of the x-axis are normalized time -- units of 2*pi*sqrt(l/g). Units on the y-axis are units of torque -- normalized by m g l.
