• cricket:

• ping-pong [1] "managed to get 75% of the balls, on average, into the target area. Because the target had a diameter of 55 cm and was located some 2.5 m away from the point of contact (near the leading edge of the table), this implies that at least 75% of the balls have been contacted with the direction of travel of the bat not varying more than 6° around the line through the center of the target. Assuming a normal distribution, the standard deviation of the direction of travel of the bat at the moment of contact must have been therefore 5.2°. As seen later, angular bat velocities at contact of 800°/s are quite common, which means that the players have to time their moment of contact with a precision of, at maximum, 5.2/0.800 = 6.5 ms"

• ball falling from ceiling McLeod:

• 2 ms temporal resolution! [2] Where can we get this?? not in Usyd lib?

• [3] need this one
