From Tim Morrison
Leslie’s letter on the butterfly effect also implies a question on the efficacy of those butterflies. If one assumes a billion butterflies (that’s just 50,000 per species) flapping their little wings three times a second for a couple of hours a day during a hurricane season of 100 days, and all we see is 100 or so hurricanes and cyclones worth the mention, then that’s 20 trillion wing flaps per achieved hurricane.
