ORIGIN OF PLANETS

SIR JAMES JEAN'S THEORY £ Sir James Jeans contributes an S eresting but necessarily incomplete g ;, icle on the origin of the planets to iscovery," says the "Manchester ardian." It is Interesting because, gely thanks to the efforts of Sir nes Jeans himself and other lucid dern writers who explain science the amateur, the origins of the verse, the solar system, and our i earth are fascinating subjects of jecture for the general public, and jmplete because certain objections Sir James's theory remain to be lained. This theory in outline is i .the planets were broken oil the , not, as Laplace thought, as a re- , of the increasing speed at which sun revolved as it shrank, but owto the tides formed on the sun by near approach of some other star. »n the second star was at its rest to the sun its power of attion would be greatest and the itest amount of matter would be ten off the sun—hence the fact that largest planets, Jupiter and Saturn, e in the middle of the sequence of ets. One difficulty still to be cleared s that if the second star's gravitaal pull was great enough to do e than cause unusually large tides ;he sun it must have passed ai a ince within the present orbit of And cury. Yet, if this was so, wny is o, the most distant-known planet, hundred times as far away as Mer's orbit, and why does Jupiter, :h according to this theory was h eal i part of the sun's mass, rotate once a en hours and the sun once In ity-six days? It can perhaps be q s ained by a grazing collision be- \vn n the two stars—but. as Sir James s says, "grazing collisions must be , very rare events in star-land." =========== ng food queues formed in CleveOhio, where nearly one-third of nhabitants are on relief, owing to ./qj emporary stoppage of relief funds.
