An elderly lady phoned her telephone company to report that her telephone failed to ring when her friends called -- and that on the few occasions when it did ring, her pet dog always moaned right before the phone rang. The telephone repairman proceeded to the scene, curious to see this psychic dog or senile elderly lady. He climbed a nearby telephone pole, hooked in his test set, and dialed the subscriber's house. The phone didn't ring right away, but then the dog moaned loudly and the telephone began to ring. Climbing down from the pole, the telephone repairman found.....
1. The dog was tied to the telephone system's ground wire via a steel chain and collar.
2. The wire connection to the ground rod was loose.
3. The dog was receiving 90 volts of signaling current when the phone number was called.
4. After a couple of such jolts, the dog would start moaning and then urinate on himself and the ground.
5. The wet ground would complete the circuit, thus causing the phone to ring.
.....Which goes to show that some problems CAN be fixed by pissing and moaning

Wilhelm Wien

Died 30 Aug 1928 at age 64 (born 13 Jan 1864). German physicist who received the Nobel Prize for Physics in 1911 for his displacement law concerning the radiation emitted by the perfectly efficient blackbody (a surface that absorbs all radiant energy falling on it). While studying streams of ionized gas Wien, in 1898, identified a positive particle equal in mass to the hydrogen atom. Wien, with this work, laid the foundation of mass spectroscopy. J. J. Thomson refined Wien's apparatus and conducted further experiments in 1913 then, after work by Ernest Rutherford in 1919, Wien's particle was accepted and named the proton. Wien also made important contributions to the study of cathode rays, X-rays and canal rays.
