1 " To grasp the reality of life as it has been revealed by molecular biology, we must magnify a cell a thousand million times until it is twenty kilometers in diameter and resembles a giant airship large enough to cover a great city like London or New York. What we would then see would be an object of unparalleled complexity and adaptive design. On the surface of the cell we would see millions of openings, like the port holes of a vast space ship, opening and closing to allow a continual stream of materials to flow in and out. If we were to enter one of these openings we would find ourselves in a world of supreme technology and bewildering complexity. "

2 " For the briefest of instants, a miles-wide hole appeared from the middle of the Earth to the top of the sky. The Moho rang like a tuning fork in harmonic response to the billion megaton impact. Seismic waves propagated in all directions, some dampening as normal, others amplified harmonically as Earth’s interior quivered like a bowl of pudding. Seismometers spiked wildly, their needles bouncing back and forth like pin-balls.A billion megatons exploded outward from the depths of the quivering Moho blasting a crater eighty-five miles in diameter and spewing billions of tons of superheated rock twelve hundred miles into space. In the blink of an eye the Earth grew a tail, as a mushroom cloud visible from Mars formed and spread, black as the Devil's eye. "

4 " This afternoon, being on Fair Haven Hill, I heard the sound of a saw, and soon after from the Cliff saw two men sawing down a noble pine beneath, about forty rods off. I resolved to watch it till it fell, the last of a dozen or more which were left when the forest was cut and for fifteen years have waved in solitary majesty over the sprout-land. I saw them like beavers or insects gnawing at the trunk of this noble tree, the diminutive manikins with their cross-cut saw which could scarcely span it. It towered up a hundred feet as I afterward found by measurement, one of the tallest probably in the township and straight as an arrow, but slanting a little toward the hillside, its top seen against the frozen river and the hills of Conantum. I watch closely to see when it begins to move. Now the sawers stop, and with an axe open it a little on the side toward which it leans, that it may break the faster. And now their saw goes again. Now surely it is going; it is inclined one quarter of the quadrant, and, breathless, I expect its crashing fall. But no, I was mistaken; it has not moved an inch; it stands at the same angle as at first. It is fifteen minutes yet to its fall. Still its branches wave in the wind, as it were destined to stand for a century, and the wind soughs through its needles as of yore; it is still a forest tree, the most majestic tree that waves over Musketaquid. The silvery sheen of the sunlight is reflected from its needles; it still affords an inaccessible crotch for the squirrel’s nest; not a lichen has forsaken its mast-like stem, its raking mast,—the hill is the hulk. Now, now’s the moment! The manikins at its base are fleeing from their crime. They have dropped the guilty saw and axe. How slowly and majestic it starts! as it were only swayed by a summer breeze, and would return without a sigh to its location in the air. And now it fans the hillside with its fall, and it lies down to its bed in the valley, from which it is never to rise, as softly as a feather, folding its green mantle about it like a warrior, as if, tired of standing, it embraced the earth with silent joy, returning its elements to the dust again. But hark! there you only saw, but did not hear. There now comes up a deafening crash to these rocks , advertising you that even trees do not die without a groan. It rushes to embrace the earth, and mingle its elements with the dust. And now all is still once more and forever, both to eye and ear.I went down and measured it. It was about four feet in diameter where it was sawed, about one hundred feet long. Before I had reached it the axemen had already divested it of its branches. Its gracefully spreading top was a perfect wreck on the hillside as if it had been made of glass, and the tender cones of one year’s growth upon its summit appealed in vain and too late to the mercy of the chopper. Already he has measured it with his axe, and marked off the mill-logs it will make. And the space it occupied in upper air is vacant for the next two centuries. It is lumber. He has laid waste the air. When the fish hawk in the spring revisits the banks of the Musketaquid, he will circle in vain to find his accustomed perch, and the hen-hawk will mourn for the pines lofty enough to protect her brood. A plant which it has taken two centuries to perfect, rising by slow stages into the heavens, has this afternoon ceased to exist. Its sapling top had expanded to this January thaw as the forerunner of summers to come. Why does not the village bell sound a knell? I hear no knell tolled. I see no procession of mourners in the streets, or the woodland aisles. The squirrel has leaped to another tree; the hawk has circled further off, and has now settled upon a new eyrie, but the woodman is preparing [to] lay his axe at the root of that also. "

5 " Snow cleaning of the world's largest telescope mirrors was an impressive sight. The optics technicians would climb into a huge telescopic boom lift and spray immense clouds of cold carbon dioxide snow and gas onto the ten meter diameter mirrors high above the floor indoors. It would cause some of the accumulated dirt to magically fall off, leaving it less dirty. "

6 " But it is the bane of psychology to suppose that where results are similar, processes must be the same. Psychologists are too apt to reason as geometers would, if the latter were to say that the diameter of a circle is the same thing as its semi-circumference, because, forsooth, they terminate in the same two points. "

8 " A physicist, an engineer and a psychologist are called in as consultants to a dairy farm whose production has been below par. Each is given time to inspect the details of the operation before making a report.The first to be called is the engineer, who states: " The size of the stalls for the cattle should be decreased. Efficiency could be improved if the cows were more closely packed, with a net allotment of 275 cubic feet per cow. Also, the diameter of the milking tubes should be increased by 4 percent to allow for a greater average flow rate during the milking periods." The next to report is the psychologist, who proposes:" The inside of the barn should be painted green. This is a more mellow color than brown and should help induce greater milk flow. Also, more trees should be planted in the fields to add diversity to the scenery for the cattle during grazing, to reduce boredom." Finally, the physicist is called upon. He asks for a blackboard and then draws a circle. He begins: " Assume the cow is a sphere.... "
9 " The Ludolphian number is fixed in eternity— not a digit out of place, all characters in their proper order, an endless sentence written to the end of the world by the division of the circle’s diameter into its circumference. "
