Claude Shannon, founding brain of the field of information theory, also loved juggling and derived the formula for the maximum number of objects one could juggle in a delightful paper.
B = (F + D) H /(V + D)
F = Flight time - how long a ball is in the air
D = Dwell time - how long a ball is held in a hand
H = number of hands
V = Vacant time - how long a hand is empty
B = number of balls being juggled
