What appears to be an enormous "metagalactic cloud," containing probably 50,000 galaxies similar to our won Milky Way, has been photographed by Harvard astronomers, according to a report published yesterday by Dr.Harlow Shapley, Director of the Harvard Observatory...
...machine used to trap this elusive iota is known as a cloud chamber. Nothing new, this apparatus has been in use since 1910; it consists of a chamber containing a mixture of liquid and gas and several lead plates, through which the cosmic radiations pass--the gas is cooled, and produces a fog track along the path of ions formed by the charged corpuscles. This track of condensed vapor can be easily seen with the naked eye and also photographed, showing up as a bright streak on the film. Thus electrons, protons and the new particles, although far too infinitesimal...
...Charles Thomson Rees Wilson of Cambridge University invented a "cloud chamber" in which tracks made by sub-atomic particles could be seen. At about the same time Hans Geiger, now of the University of Tubingen, invented a cylindrical "counter" which crackles every time a particle enters it. Physicists use both devices, alone or together, to record the presence of and identify cosmic rays, gamma rays, X-rays, photons, electrons, protons, positrons, neutrons...
...week that they had discovered a brand-new cosmic particle which the heavens rain upon the earth. It has a negative electrical charge like an electron, but seems to weigh ten times as much and have a thousand times as much energy, easily passing through four Geiger counters, two cloud chambers and seven inches of lead...
...modern incidents with which the vast attitude is ending are as self-explanatory as cheeks marked by anguish or a hand that falls exhausted." Spain's last 300 years Ortega calls a "long coma of egotism and idiocy . . . today we are not so much a people as a cloud of dust that was left hovering in the air when a great people went galloping down the high road of history." The sectionalism which has marked modern Spanish history, notably the movements for Basque and Catalan nationalism, have their roots. Ortega thinks, deep in the past. It took a strong...
