...device is called ElectroCardioAnalyzer. It is a miniaturized computer as well as a simplified electrocardiograph. By comparing a subject's graph with fixed standards that have been programmed into the machine beforehand, it can detect abnormal electrical activity in the heart. When it -does so, warning lights flash on, and the technician knows that this patient must be referred to the cardiologist...
...Rhode Island Auditorium that the Who often end with such a gory finale and that the signal for it to begin is the song "My Generation".

Townshend starts pounding the floor with his guitar--plays a little on it--then crashes it into the nearest amplifier again and again hitting the sides and the delicate loudspeaker fiber...
This joyous fellow feeling does come about, it comes in a flash, a feeling of unity not just with flowers and trees and animals (that's easy to achieve) but with other self-sustaining human egos as well...
...atoms (one for every 5,000 aluminum atoms) that cause the laser action. Excited Atoms. Both ends of the crystal rod are highly polished and silvered to act as mirrors, one highly reflective, the other partially transparent. Wrapped around the rod in the form of a coil is a flash tube similar to the strobe lights used by photographers...
When a pulse of electricity is fired through the tube, it gives off a brief, intense flash of light. Inside the ruby rod, the chromium atoms are highly excited by the light flash; their electrons temporarily absorb excess energy. Then, as the electrons fall back toward their normal energy levels, each emits a photon. Some of the photons pass through the transparent walls of the ruby rod and are lost. But many hit the mirrors at either end of the rod and are reflected back to the opposite mirror. As they bounce back and forth along the rod, they stimulate...
