Wow, I like read that exact same page off a Google search.:laugh:

I spent the first 20 minutes poking through Wolfram's mathweb stuff, trying to decide what type of series it was. It wasn't until I stumbled upon the Wikipedia page for series that it listed this series as the harmonic series, along with approximations. I got a solid A on this stuff in CalcIII back in college - now I'm looking at it through what seems to be foggy, frosted glass only a handful of years later :-O -- Russell Morris Morbo: "WINDMILLS DO NOT WORK THAT WAY!"

That works on the vacuum principle too, eh?
a wing will create small pockets of (partial) vacuum as air moves around it. it's under debate as to whether this is the actual source of lift or not. Cleek | Image Toolkits | Thumbnail maker

My Physics teacher would have ranted at you! "Vacuum is a total absence of air. How can you have a partial total absence? You mean 'a pocket of lower air pressure'" Phil

1/2 + 1/3 + 1/4 + 1/5 + 1/6 + 1/7 + 1/8 ...... When will the sum of this series exceed 100 ? Will it EVER ? For the thinkers, Why does a candle extinguishes when we blow on it? (Never paid attention to it, right?) Looks simple but it isn't ! * you are right, this guy has got nothing to do... but if you read this we are in the same boat --- My Unedited article^

Summation applet[^]. 1) Click the [Applet] button, a popup window is seen. 2) Input 1/(n+1), 3) Click [Auto] button. :-D [Edit] Ouch! Overflow ... ;P [/Edit]

Yes, I saw it. It said that the sum goes to infinity as n goes to infinity. But the question was when does the sum reach 100? If ever. You definitely got the "if ever part", but that left the much more difficult problem of what is the value of n when the sum equals 100.

I order of magnituded the eta for 100 here. Unless there's an analytical method getting a precise value is impossible since bruteforce isn't an option. http://www.codeproject.com/script/comments/forums.asp?msg=1480757&forumid=1159#xx1480757xx

We blow the air away creating a small vacuum pocket and a fire cannot burn in a vacuum. That's my guess anyway :-) Regards, Nish

Sorry. You cannot blow into an area and create a vacumm caused by no matter in an area. This is physically impossible through the laws of physics. Carbon Dioxide doesn't put out the flame either because your breath contains a large amount of oxygen in it. If I remember correctly, the flame goes out due to over supplying oxygen to the flame. Similar to why an airplane engine will stall if you make the fuel too rich.
