# Thread: he he Simple Solution

1. ## he he Simple Solution

"When NASA first started sending up astronauts, they quickly discovered
that ball-point pens would not work in zero gravity. To combat this
problem, NASA scientists spent a decade and \$12 billion developing a
pen that writes in zero gravity, upside-down, on almost any surface
including glass and at temperatures ranging from below freezing to
over 300 C.

The Russians used a pencil."

PS: there is actuallly a debate going on this whether this is true or not! so dont pounce on me about its validity!

2. yeah even i heard taht ...

but THIS (what am gonna write) is a true story:
US Airforce wanted a device which could write at high altitudes ... as u might be knowing at high altitudes the air pressure is low (even if the cabin air pressure is controlled it is lower tahn atmospheric ... anyway u just need to travel in air force plane to know the diff ) so the low air pressure causes ink leaks in a fountain pen ...

so they damanded a device which wont leak like a fountain pen ...
after much research came out the first ball pen (forgot which compnay made it) ... which doesn't leak due to pressure disturbances ...

obviously in this case also they cuddve used a pencil ...
***wonders***

3. As far as i knew....as we go higher..the pressure increases..!! That is low pressure at the bottom..and hig pressure in the hills......*ok am not sure*
....Now on offences meant..

4. no higher pressure at bottom.....less on top. Simple logic.....if u are on the sea surface u are farther from the sky so more air above u => more pressure......if ur on everest then u are closer to the sky and there is less air above you => less pressure!!!

5. ^^^ yeah guess that pretty much sums up waht i had to say ...

Physiscs 101:
Pressure exerted by fluid column = density of fluid * accl due to gravity * height of the fluid column ... in this case u'll havt ause calculus coz the density itself is changing ... but then the equation kinda sums it up pretty neatly ...

russians..hmmm

maria sharapova is hot.
sometimes commons sense is more imp than scientific solutions.
o well..dunno if this is true..tho..still makes americans look like dweebs.

7. OKies....But i knew atmospheric pressure is related to temperature.......More is the temperature the less will be the pressure as the density decreases...(volume increases)...!!

Anyway, i'll refer to some books b4 making any further comments..

Nevertheless very funny, reps for you.

Pressure is directly proportional to Temperature. Volume is inversely proportional to Pressure.

I got this in an email a few years ago titled:

Right Focus: A case study

10. well nik waht u say is partially true ... but u have added 2 and 2 and made 'em 22 ...

density of air at sea level is higher than at higher altitudes ... nothing to do with temperature ...

11. um so a million miles from earth's surface will be the highest possibleair pressure???? :D !! wont it be almost a vacuum? i know this isnt exact but the correct equation for pressure has alrady been posted...

similarly if you go high in altitude the amount of air putting pressure on your head reduces thats why there is a low presure....and the moment you come down to earth ...the presure increases cuz the air above you is more!!

13. Ther is one more thing like this.

"One of the most memorable case studies on Japanese management was the
case of the empty soap box, which happened in one of Japan's biggest
cosmetics companies. The company received a complaint that a consumer
had bought a soap box that was empty. Immediately the authorities
isolated the problem to the assembly line, which transported all the
packaged boxes of soap to the delivery department. For some reason, one
soap box went through the assembly line empty. Management asked its
engineers to solve the problem.

Post-haste, the engineers worked hard to devise an X-ray machine with
high-resolution monitors manned by two people to watch all the soap
boxes that passed through the line to make sure they were not empty. No
doubt, they worked hard and they worked fast but they spent a whoopee
amount to do so.

But when a rank-and-file employee in a small company was posed with the
same problem, he did not get into complications of X-rays, etc., but
instead came out with another solution. He bought a strong industrial
electric fan and pointed it at the assembly line. He switched the fan
on, and as each soap box passed the fan, it simply blew the empty boxes
out of the line."

14. yup this is the second part of that ........i was looking for it but couldnt find it......thx illusion

15. nice one , well it can be proved if right or wrong unless taken from a proper source !! but nice one !!
