An Irishman, Englishman and Scotsman go into a pub and each order a pint of Guinness. Just as the bartender hands the mover, three flies buzz down and one lands in each of the pints.
Inge LehmannBorn 13 May 1888; died 21 Feb 1993 at age 104.Danish seismologist and geophysicist who was the first person in that field in her home country, and the first true female geophysicist in the world. In a paper published in 1936, she identified the Lehmann Discontinuity in the seismic structure of the earth which marks a previously unknown boundary at the solid inner core of the Earth. Titled simply “P” (for Prime), this paper was based on her interpretation of worldwide shock wave records from a large earthquake near New Zealand in 1929. She continued to add to the knowledge of the earth's internal structure by studying the body-wave amplitudes and travel times of seismic waves in the upper mantle. She once described herself as “the only Danish seismologist” but received awards from around the world.« |
