| Galton's delta | A more or less well-marked triangle, in a fingerprint, on either side where the straight ridges near the joint of the distal phalanx are succeeded by arches, loops, or whorls. See: Galton's system of classification of fingerprints. Synonym: triradius. (05 Mar 2000) |

| Galton's law | In a population mating at random, the progeny of a parent with an extreme value for a measurable phenotype will tend on average to have values nearer the population mean than in the extreme parent. See: law of regression to mean. Synonym: law of regression to mean. (05 Mar 2000) |
| Galton's system of classification of fingerprints | A system of classification based on the variations in the patterns of the ridges, which are grouped into arches, loops, and whorls (A.L.W. Or arch-loop-whorl system). "Arches are formed when the ridges run from one side to the other of the bulb of the digit, without making any backward turn, but no twist; whorls, when there is a turn through at least one complete circle; they are also considered to include all duplex spirals." The abbreviations used in making a record of fingerprint's are: a, arch; l, loop; w, whorl; i, loop with an inner (thumb side) slope; o, loop with an outer (little-finger side) slope. The ten digits are registered in four groups as follows, distinguished by capital letters: A, the fore, middle, and ring fingers of the right hand; B, the fore, middle, and ring fingers of the left hand; C, the thumb and little finger of the right hand; D, the thumb and little finger of the left hand. See: dermatoglyphics. (05 Mar 2000) |
| Aston, Francis William | <person, radiobiology> Physicist at Cambridge University who invented the mass spectrometer in 1919, a device which could measure the mass of individual atoms. This device led to his discovery that the helium nucleus was less massive than the two hydrogen nuclei which could have formed it (implying that the missing mass could somehow be converted into energy through the process of nuclear fusion).

| Crick, Francis | <person> An English biologist born in 1916 who was one of three people to win the Nobel Prize in 1962 for the category of physiology or medicine. He and James Watson, an American biochemist and alumnus of Indiana University, discovered the double-stranded helix structure of the DNA molecule and built the Watson-Crick model of this structure. Their work was heavily based on the work of Maurice Wilkins (who also won the Nobel Prize in physiology or medicine in 1962) and Rosalind Franklin (who died before the 1962 Nobel Prize winners were selected). The model they postulated is the accepted model used today. Lived: 1916- (13 Nov 1997) |
