FIRST GLIMPSES OF A NEW WORLD

Dr. George Roemmerts “Microvivarium,” which projects enormously enlarged images of living microscopic plants and animals on a screen, is a prime attraction of the Hall of Science at the Century of Progress. It has given thousands who have never looked through a microscope their first view of the amazing life that can be found in a drop of water.

MOST INTELLIGENT COLLEGE MEN CHOOSE MOST INTELLIGENT MATES

The old idea that men prefer “dumb” women for wives is disproved by a study made by Wesley Carroll, graduate student at Iowa State College, under the direction of Dr. M.F. Fritz.

Intelligence ratings of boys and girls whose engagements were announced in the college newspaper show that the men tended to choose girls of equal of superior intelligence, either intentionally or unintentionally.

Nearly 200 announcements of engagements were collected from the files of the newspaper. For 126 of the couples, the scores that both boy and girl made in the college aptitude tests were available.

The men tended to choose women who were mentally equal or superior, Dr. Fritz said, explaining that when the rating of each boy was compared to that of his intended wife, a slightly positive correlation was discovered.

HIGH-VOLTAGE NEUTRONS MAY BE MOST EFFECTIVE ATOM SPLITTERS

Artificially produced neutrons, made in the Norman Bridge Laboratory of Physics at Pasadena, Calif., by the use of high voltage rather than radium, may prove to be more effective in splitting the hearts of atoms than anything previously known.

In the brief time that neutrons have been known, they have proved particularly useful for atom smashing. It does not seem to matter how much energy they have. They slip into atomic hearts or nuclei and make trouble that gives physicists important information on the composition of matter.

Neutrons are released from atomic hearts by artificially speeded helium ions corresponding to radium-emitted alpha particles but with lower energy.
