...Ceylon, from the Equator to within 350 miles of the North Magnetic Pole, they have carried a cosmic quest which has cost at least two lives. It has been found that cosmic rays are either particles of matter or units of radiation, or both, with energies of billions of electron volts, energies beyond the power of any man-made device to reproduce. They bombard Earth continually from all directions. The most powerful can penetrate 3,200 ft. of water or 290 ft. of lead. Estimate: 30 cosmic rays pass through every human body every second. And it is suggested that...
...must be. They told of experiments presaging the production of a radio-phosphorus which would emit neutrons (emitted by no natural radioactive substance). And they spoke of work indicating the existence of the neutrino, an ultimate particle lacking electrical charge like the neutron, but small in mass like the electron. Many a physicist has held the neutrino's existence called for on theoretical grounds, has hesitated to sign its birth certificate because it eludes experimental observation...
...Like the electron, the gene has eluded the eye of Science while manifesting itself by its works. "Gene" is the name by which geneticists agreed to call the mysterious heredity-transmitting agents strung along the length of the chromosome. As minute streaks in body cells, the chromosomes were visible under the microscope; their component parts were not. Last week a long step toward visual study of genes seemed to have been taken by Dr. Calvin Blackman Bridges of the Carnegie Institution, working at the Station for Experimental Evolution in Cold Spring Harbor...
...readers in thin, lucid books. Sir James again led his hearers over the trail from the comfortable Victorian universe of jelly-like ethers, billiard-ball particles, gears and levers to the disconcerting, fantastic universe built by Rutherford, Planck. Bohr, Einstein. Heisenberg. Schrodinger, Dirac and others where the electron dances beyond space and time in a field of mathematical formulae...
...attacked the orthodox teaching of physics that electric current is a flow of matter having mass. A current of one ampere is a flow of 6,281 billion billion electrons per second past a given point. An electron is a particle of matter weighing 0.8999 billionths of a billionth of a billionth of a gram. But was electric current tangible...
