...determined that the heredity-transmitting DNA molecule is shaped like a spiral staircase. Al though they had no way of taking a firsthand look at their discovery, they managed to deduce a detailed description of the now famous "double helix" that paved the way for the new science of molecular biology and won them the Nobel Prize. For all the work that has been done in the field since Watson and Crick made their pioneering studies in 1953, no one had been able to display any hard and fast visual evidence to confirm the spiral structure of DNA. Now that...
They don't think that molecular biology is more important than people...
...with Adelaide the maid, then flirts with his brother-in-law's wife and finally consorts with an ex-nun named Lisa. She and a forbearing homosexual nurse called Nigel are the enigmatic characters, familiar in Murdoch fiction, who stir the emotional chemistry of the others into molecular groupings and regroupings...
Polyethylene oxide, the material that eased Highburton's passage, is known to chemists as a long-chain polymer because it consists of lengthy strings of linked molecules. In the water near a ship, the molecular chains act much like an array of thin parallel tubes, allowing water to flow smoothly back along the hull but retarding its movement in any other direction. As a result, the friction-building turbulence that is normally generated by a ship slicing through the water is sharply reduced...
Their most secure foothold is in science. They are telling us things about molecular structure and aero-dynamics. In hard-to-quantify sciences like linguistics or psychology they are partly hamstrung; they can't tell the difference between sentences like "Fruit flies like a banana" and "Time flies like an arrow." But they have created their own languages which people must use to communicate with them, and these computer languages throw light on the mysteries of human speech...
