 The Critical Path

H UMANITY IS MOVING EVER DEEPER into crisis—a crisis without prec¬ edent. av upon completely transforming omnidisintegrated humanity from a complex of around-the-world, remotely-deployed-from-one-another, differently col¬ ored, differently credoed, differently cultured, differently communicating, and differently competing entities into a completely integrated, comprehensively interconsiderate, harmonious whole. Second, we are in an unprecedented crisis because cosmic evolution is also...

 A Naturalist's Code

Of course, naturalists’ activities themselves can go astray or fail to provide their full benefits. Rachel Carson warned that “it is possible to compile extensive lists of creatures seen and identified without ever once having caught a breathtaking glimpse of the wonder of life.”22 A concern to have the newest, fanciest gear has taken many a birdwatcher away from simplicity and frugality! As with hunting’s “sportsman’s code,” a “naturalist’s code” might help prevent these ...

 Dimensions of an Atomic Size Computer

If we somehow manage to make an atomic size computer, it would mean that the dimension, the linear dimension, is a thousand to ten thousand times smaller than those very tiny chips that we have now. It means that the volume of the computer is 100 billionth or 10^-11 of the present volume, because the volume of the "transistor" is smaller by a factor of 10^-11 than the transistors we make today. The energy requirements for a single switch is also about eleven orders of magnitude smaller than t...
