Julius Elster

Died 6 Apr 1920 at age 65 (born 24 Dec 1854).Johann Philipp Ludwig Julius Elster was a German physicist who had a very productive collaboration with Hans Geitel, and have been called the “Castor and Pollux” of physics.They constructed the first photelectric cell, and photelectric photometer as part of their study of the photoelectric effect and thermal electron emission. They declined to patent these inventions, preferring to share the benefits. From 1884, they researched electrical phenomena in gases, atmospheric electricity, measured the electrical field of the Earth, and in 1899 were the first to determine the charge on falling raindrops from thunderclouds. When they investigated radioactivity, they regarded it as due to a spontaneous release of energy by the atoms. They showed that lead is not in itself radioactive, and that conductivity of the atmosphere was due to ionization from radioactive substances.«

Outdone

A strong young man at the construction site was bragging that he could outdo anyone in a feat of strength. He made a special case of making fun of Morris, one of the older workers.

After several minutes, Morris had had enough. "Why don't you put your money where your mouth is?" he said: "I will bet a week's wages that I can haul something in a wheelbarrow over to that outbuilding that you won't be able to wheel back."

"You're on, old man," the braggart replied: "It's a bet! Let's see what you got."

Morris reached out and grabbed the wheelbarrow by the handles. Then, nodding to the young man, he said, "All right. Get in."
