Faint Current. Republic's tiny protons, which are the nuclei of hydrogen atoms, act exactly like small bar magnets. When they are placed in a magnetic field, they tend to line up like a bunch of compass needles. If the magnetic field changes direction, it tries to pull the protons around with it. But protons have a mysterious property called "spin" that makes them react like small spinning wheels. When the magnetic field changes direction, they do not follow obediently. Instead, they resist the turning motion, just as if they were gyro wheels...
Strauch has used high energy protons from the Harvard Cyclotron to investigate the structure and properties of nuclei. He has also investigated the properties that have been found in recent years in the world of nuclear physics...
...clever instrument that can tell the difference was the hit of an erudite conference that met at Venice to discuss new methods of archaeology. Called a proton magnetometer, the gadget is based on a principle of nuclear physics discovered only a few years ago. The nuclei of hydrogen atoms (protons) are, in effect, tiny magnets, and they line up like compass needles parallel to the earth's magnetic field. When nudged out of alignment, they oscillate for a few seconds, the speed of their oscillation changing with the local strength of the earth's magnetism. Buried objects that...
...than anybody and have the right to mistreat and humiliate others." He singled out the notorious Revolutionary Defense Committees-spies stationed in every city block, in all factories and farms-for special censure. And then he made his attack categorical: "The revolution has to re-educate all the revolutionary nuclei, and needs to revise the entire political apparatus of the revolution...
Scientists have long used high-energy protons (fundamental particles that form the nuclei of hydrogen atoms) as tools to explore the secret innards of matter. Two enormous accelerators, one at Brookhaven National Laboratory, Long Island, the other near Geneva, Switzerland, spew out protons with 30 billion electron-volts of energy. Yet in some ways protons are clumsy tools for basic research; for many subtle experiments, electrons (much lighter negative particles of electricity) are better. But electrons are so much more difficult to handle that scientists have never been able to give them really high energy. The Cambridge accelerator is designed...
