A very successful businessman...
A very successful businessman had a meeting with his new son-in-law. I welcome you into the family,” said the man. “To show you how much we care for you, I am making you a 50-50 partner in my business. All you have to do is go to the factory everyday and learn the operation.”
The son-in-law interrupted. “I hate factories. I can’t stand the noise.” “I see.” replied the father-in-law, “Well, then you’ll work in the office and take charge of some of the operations.” “I hate office work,” said the son-in-law. “I can’t stand being stuck behind a desk.” “Wait a minute,” said the father-in-law. “I just made you half owner of a money-making industry, but you don’t like factories, and won’t work in an office. What am I going to do with you?” “Easy,” said the son-in-law. “Buy me out.”

Wilhelm WienBorn 13 Jan 1864; died 30 Aug 1928 at age 64. 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. |
