NASA Mars Mission

NASA was interviewing professionals they were planning on sending to Mars. The touchy part was that only one guy could go and it would be a one way trip, the guy would never return to Earth.

The interviewer asked the first applicant, an engineer, how much he wanted to be paid for going.

"One million dollars," the engineer answered. "And I want to donate it all to my alma mater -- Rice University."

The next applicant was a doctor, and the interviewer asked him the same question.

"Two millions dollars," the doctor said. "I want to give a million to my family and leave the other million for the advancement of medical research."

The last applicant was a lawyer. When asked how much money he wanted, he whispered in the interviewer's ear, "Three million dollars."

"Why so much more than the others?" the interviewer asked.

The lawyer replied, "You give me three million, I'll give you one million, I'll keep a million, and we'll send the engineer."

Screw-blank feeder mechanism

In 1856, Cullen Whipple, of Providence, RI, patented a screw-blank feeder mechanism (U.S. No. 15,052). In Oct 1840, he was one of ten incorporators of The New England Screw Co. He invented a machine for the company to use cutting the threads of screws (patented 18 Aug 1842) which he later improved by adding more cutters to also point the screws in the same machine (patent No. 9,477, 14 Dec 1852). He patented various other devices for improving the manufacture of screws. He has been credited* as the inventor of the first practical machine for pointing screws. Early screws had no point and required that a starter hole be drilled before use.«[Note: Famous First Facts by Joseph Nathan Kane incorrectly cites this screw-blank feeder mechanism's 3 Jun 1856 date and patent number as the first practical screw-pointing machine patent. In fact, Whipple invented his screw pointing machine four years earlier - in 1852.]
