...Your diagram of tactical nuclear weapons graphically illustrates the steps of escalation each side would inevitably be forced to take once the very smallest A-weapon had been used. As part of the same inexorable process, strategic weapons must follow until the "ultimate" (100-megaton?) bomb would be launched by the side still able to do it. This elementary fact must be brought home to those who still cannot grasp...
Micrometer Precision. About as big as its owner's fist, the human kidney is a biochemical filter with incredibly delicate powers of discrimination. It is also a prodigious worker (see diagram, left). All the water that anyone consumes in food or drink must go into the blood and be extracted by the kidneys before it can be voided as urine-contrary to the beer drinker's cliche "It goes right through you." Kidneys also work fast: the malodorous sulphur compound in asparagus is extracted and begins to be excreted in a couple of hours...
Each kidney contains a million filtration units called nephrons. Each nephron is made up of a tuft of microscopic blood vessels, called a glomerulus, and each of these has a minute tubule at tached (see diagram, right). When blood flows into the glomeruli and around the tubules, one-fifth of its water content is led aside for finer filtration. One hundredth part of this is extracted and passes eventually to the bladder...
...Chicago doctors have stopped bleeding from aneurysms (ballooned-out arteries) in the brain's arterial roundabout, the Circle of Willis, by drilling a hole in the patient's skull under a local anesthetic and inserting a stainless steel needle (see diagram). This has a hairlike electrode tip only 1/250 in. in diameter, which is positioned precisely by a double-grid system of X rays (see photos). The tip is the positive electrode for a minute current. The negative electrode is attached outside the skull. Within half an hour the iron in the electrode is "plated off" (in effect...
William Golding's latest novel is more a diagram than a story. He bases the book on a tension between the spiritual (the spire) and the worldly and instinctual (the foundations...
