...Swedish film Of Love and Lust takes its title from a book by Theodore Roik and comprises adaptations of two short stories by August Strindberg. This juxtaposition is appropriate, because the stories are valuable both as entertainment and as psychological studies. One, the story of dust, is a bitter, sardonic chronicle of a marriage without love, and the other, that of love, is a delightfully pointed satire, of Ibsen's A Doll House...
Yale's Gold Dust Twins, Jim Stack in the 600 and Tommy Carroll in the 1000, both were soundly beaten, in a generally tepid night for the Blue...
Mason's next step was to cool droplets containing microscopic nuclei made of substances that are common in powder-fine dust blown up from the earth's surface. A few kinds proved almost as effective as silver iodide smoke, but most required very low temperatures before they could turn cold clouds into snow...
...Trained Dust. In further experiments, Mason showed that some kinds of common natural dust can be "trained" to collect ice. Particles of kaolinite (common in clays) do not act as ice-forming nuclei above 16° F., which is colder than the tops of many clouds. But when kaolinite particles have once had ice crystals on them, and when this ice has evaporated, they are able to form fresh crystals in clouds no colder than...
...evaporates, but tiny bits remain trapped in crevices. When these ice-seeded particles get mixed with a moderately cold cloud, they make it yield snow or rain. Mason argues that much of the earth's precipitation is wrung out of clouds by just such "trainable" earth-dust particles. Kaolinite and other kinds of clay are extremely cheap, so it may be possible to make sure that the air over thirsty countries always has plenty of just such particles-always ready, willing and able to precipitate clouds...
