..."when a critical mass of truly committed sardines is reached - not a huge number like 50 percent or 80 percent of the school, but 15 to 20 percent who are truly committed to a new direction - the rest of the school suddenly turns and goes with them - almost instantaneously!"
Fun background on blue whales:
...a blue whale is the largest mammal on earth. An adult blue whale is the length of 2 1/2 Greyhound buses put end to end, weighs more than a fully loaded 737, has blood vessels large enough for an adult to swim down, a heart the size of a Volkswagon Beetle, and a tongue 8' long that weighs 6000 lbs. A baby blue whale is estimated to gain more than 50 pounds an hour from birth to the end of it's first year (now that's a high fat diet - certainly not Atkins). In addition, the blue whale is not only the biggest but also the loudest animal. At 190 decibels, a blue whale's call is louder than a jet (140 decibels), and much louder than a person can shout (70 decibels)A little known fact is that a blue whale is so large that when it decides to turn around, it can take 2 to 3 minutes to turn 180 degrees so that it can swim in the opposite direction. As a result, some people have drawn a strong parallel between blue whales and our school systems
