A lawyer walks into a bar and sits down next to a drunk who is closely examining something held in his fingers. The lawyer watches the drunk for a while till he finally gets curious enough to ask what it is.

"Well," said the drunk, "it looks like plastic and feels like rubber."

"Let me have it," said the lawyer. Taking it, he began to roll it between his thumb and forefinger, examining it closely. "Yes," he finally said, "it does look like plastic and feel like rubber, but i don't know what it is. Where did you get it?"

"From my nose," the drunk replied.

Eugen Goldstein

Died 25 Dec 1930 at age 80 (born 5 Sep 1850).German physicist who discovered and named canal rays (1886) which emerge through holes in the anodes of low-pressure electrical discharge tubes (later shown to be positively charged particles). Earlier, he coined the term “cathode ray”(1876) emitted from a cathode. He was the first to see that they could cast a shadow, and were emitted at right angles to the surface. He also investigated the wavelengths of light emitted by metals and oxides when canal rays impinge on them. When the Berlin Urania, opened in 1889 it had five scientific departments and a “science theatre,”it was Goldstein who had recommended the “hall of physics in which the visitor could experiment on his own.” Students of his who continued his work included Wilhelm Wien and Johannes Stark.«Image: The tube with which Goldstein discovered canal rays in 1886.
