### 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."

### Shakuntala Devi

Died 21 Apr 2013 at age 83 (born 4 Nov 1929).Indian computer and astrologer who demonstrated her gift as an arithmetical prodigy in public performances (beginning at age 6 years old), rapidly computing answers to addition of several up to 13-digit numbers. Using her mental skills, she applied shortcuts using mathematical algorithms, though she could not explain that ability. Her calculations included using large numbers in multiplication and division of large numbers. She also quickly gave square and cube roots, and could name the day of the week for any date in the last century. Examples include taking the cube root of 188,132,517 or naming which days of the week the 14th of each month occurred in 1935. Her skill was one of computation, but she did not have a photographic memory for other facts, and could have memory lapses such as recognizing people met in years past.«
