...apathy even among the Boston residents, the work was slow. Now, O'Donnell reports, there is more interest in Hynes here, but there is still lots of room for anyone who wants to join the group. At Radcliffe, Linda Cabot '50 and Elaine Tanner '50 are the nuclei for the Hynes forces...
High Hopes. If Radiologist Harvey's estimate is right, every day for the next two to three weeks more & more cancer cells in and around the patient's larynx will have their nuclei killed by the betatron's almost irresistible rays. Patients with deep-seated malignancies in other parts of the body also started treatment this week. Soon Dr. Harvey should be able to tell whether medicine's new weapon, which now costs $85,000, shows promise. If the answer is favorable, high-powered, penetrating X rays may be used in about 10% of cancer cases...
...this point the scientists use the magnetic properties of atomic nuclei. When certain materials (e.g., lithium fluoride) are placed in a strong magnetic field, the nuclei of their atoms also line up. When the magnetism is removed, the lithium fluoride gets colder. This method promises to yield a temperature only one-millionth of a degree above absolute zero...
...quantum" of the quantum theory). Gamow suspects that this missing length may turn out to be about 10 -13 centimeter (one ten-trillionth of a centimeter). A length close to this shows up as the radius of an electron, and as the effective range of forces in the atomic nuclei. "All kinds of physical considerations," says Gamow, "become senseless when we try to apply them to distances smaller than 10 -13 centimeter...
...knows for certain what makes supernovae explode. One theory: when they reach some unstable state their matter "collapses." The electrons circling around the atomic nuclei move inward and combine with the equal number of protons that they find in the nucleus, forming neutrons. These occupy very little space compared with the original atom, and can pass through ordinary matter...
