Who is associated with coming up with "back-of-envelope calculation?"?
361336
The phrase is derived from the practice of quickly jotting down calculations on the piece of paper nearest to hand, which in pre-email days often meant the back of an envelope. Another possible origin for the phrase is a widespread myth that Abraham Lincoln wrote the Gettysburg address on the back of an envelope while on the train to Gettysburg.\n\nThe physicist refered to by your professor is Feynman.

There is a good discussion on this on a snopes.com messageboard (see link below). The best guess appears to be Air.

If you mean that the Chinese came to tell him that they found the back doors in XP... then by golly you may be on to something.  I wonder what that conversation was like.  I bet the NSA knows huh!  To be a fly on that wall...  would be so telling.  I bet bill gates himself can't pass gas without them (NSA) hearing it.

From  Word Detective :\n\n""Pushing the envelope" is a good example of how jargon -- the specialized or technical vocabulary of a group or profession -- gradually enters general usage. "Pushing the envelope" comes from the jargon of test pilots, and has actually been around since the end of the Second World War. The "envelope" involved is a sort of visual metaphor for the technical limits of a high-performance aircraft. A graph of such an aircraft's performance would appear as a rising slope as the craft approaches its limits of speed and stress, then fall off rapidly (putting it mildly) when the plane exceeds its capacity and the pilot loses control. Safety, relatively speaking, lies within these limits, or "inside the envelope." A pilot who "pushes the envelope" and tries to exceed the known capabilities of the aircraft risks what engineers delicately term "catastrophic system failure," otherwise known as a crash. \n\nBecause "pushing the envelope" had such a esoteric origin, it took a best-selling book -- Tom Wolfe's "The Right Stuff" in 1979 -- and later the popular movie "Top Gun" to introduce it to the general public. Since then it has begun to crop up in increasingly non-technical contexts, to the point where it is now a currently trendy metaphor for simply "pushing it," or testing the limits of what is permissible in a given situation."

Probably some random person entered that info under the wikipedia entry- i've never heard that before either.

That's a tough one.  Thinking the only way would be to verify source of how/where data got input?\nHow else could this be done, plus this would be time consuming.\nDo you have more specifics?

Although you can design almost anything on the back of an envelope, the word itself stems from envelop, to put a cover about or to surround (like placing a letter within an envelope?).  Let's say your machine is a race car that you design and extensively test at a maximum (red line) speed of 130 MPH and at coolant temperatures not exceeding say 212F with gas (rather than kerosene).  That is all part of your operating envelope.  Anyone exceeding your operating limits (taken collectively as your operating envelope) have no one too blame but themselves if the car fails.  The operating envelope may be complex, e.g., you can take sharper corners but only at reduced speed, etc.  Humans often operate outside their envelopes and achieve great things (or pulled muscles?).

I checked into it a while back.  They usually want money up front for a 'list' of companies that employ, supposedly, people to stuff envelopes.  After you get the list, you are to contact these companies and try to get work from them.  Yes, a scam.

First of all, every one thinks Google algorithm is a secret. By the way, Serge Brin and Larry Page them selves published a research paper informing about the technology in 1998, when Google was a prototype called as Back Rub. Here is the link:\n\nhttp://www-db.stanford.edu/~backrub/google.html

Perhaps you mean the Billback cost recovery system described in the source link.  Good luck.

you can try it here.\nhttp://www.abika.com/Reports/Freebackgroundchecksandverifications.htm\n\nbut why would u need to do this? anyways, the website is not as accurate as systems like FBI or any government related system.

First of all, it seems implausible that Britain would write the Note in a German code that they were just figuring out how to dechiper. And in 1917, Arthur Zimmerman himself confirmed that the Note was genuine, and in October 2005 an original typescript was uncovered.\n\nSo I'm betting heavily on its authenticity.

just work backwards to find out the logic in it. That way you'll get why it works that way it did

EXCELLENT QUESTION.I was wondering about the huge computer  vs paper ballot vote this election.Sounds like another election scam in the making
