Except that computer people use 2 as a base raised to multiples of powers of 10, instead of 10 raised to multiples of powers of 3 because powers of 2 are handier for them, but they also want to stay somewhat close to the values of 10 most folks are used to.

| "For 2 years the Boeotians had timidly ringed their rich farm-land with an enormous wooden stockade, in a failed effort to keep the Spartans off their grain-fields. But then inexplicably under Epaminondas the army chose to fight, and destroyed, the best of the Spartan troops in 371 [BCE], and within months drove into the heart of Sparta itself. Yet by 362 [BCE] at the battle of Mantinea the Boeotian army collapsed and retreated the moment Epaminondas perished at the front of the phalanx, never to mount a serous invasion southward again. The great democratic militias are by definition armies of a season and of a particular spirit, and it may be that the Boeotians' training, elan, and sheer anger was never quite again what they were during that miraculous year after Leuctra. Just as there was not an army in the world that could have stopped Sherman as he neared Savannah, or Patton as he dashed eastward in 1944 August, so too in the winter of 370 [BCE] no force in Greece could have withstood Epaminondas's descent into Sparta." --- Victor Davis Hanson 1999 _The Soul of Battle: From Ancient Times to the Present Day, How 3 Great Liberators Vanquished Tyranny_ pp50-51 |
