Fish trap

This fisherman goes to the river to check an illegal fish trap that he owns. He looks around to make sure there are no Fishing Inspectors about and proceeds to pull the fish trap out to check it.

An Inspector steps out of the bushes, “Ahha!” he said and the fisherman spun around and yelled “Shiiiit!”. The Inspector, who wasn’t expecting such a response said “Settle down, I’m the Fishing Inspector”.

“Thank God for that” said the fisherman, “I thought you were the bugger who owned this fish trap”.

Parity conservation disproved

In 1956, the formerly believed “law” of conservation of parity was disproved in the first successful results from an experiment conducted by Madame Chien-Shiung Wu at Columbia University on the beta-decay of cobalt-60. It had been suggested in a paper published by Tsung-Dao Lee and Chen Ning Yang on 1 Oct 1956. There had been problems to overcome working with the cobalt sample and detectors in a vacuum at a working temperature of one-hundredth of a kelvin. Wu's team repeated the experiment, doing maintenance on the apparatus as necessary, until on 9 Jan 1957 further measurements confirmed the initial results. Leon Lederman performed an independent test of parity with Columbia's cyclotron. They held a press conference on 15 Jan 1957.«
