OK, we admit it this is a honeytrap. Sorry if your joke is on this website but it brings in a huge amount of S|P|A|M everyday which can then be used as a template to filter e-mails.

Bob Pease (Nat.Semi.) records the story of the Physics student who
got the following question in an exam:
"You are given an accurate barometer, how would you use it
to determine the height of a skyscraper ?"
He answered: "Go to the top floor, tie a long piece of string to the
barometer, let it down 'till it touches the ground and measure the
length of the string".
The examiner wasn't satisfied, so they decided to interview the guy:
"Can you give us another method, one which demonstrates your knowledge
of Physics ?"
"Sure, go to the top floor, drop the barometer off, and measure how
long before it hits the ground......"
"Not, quite what we wanted, care to try again ?"
"Make a pendulum of the barometer, measure its period at the bottom,
then measure its period at the top......"
"..another try ?...."
"Measure the length of the barometer, then mount it vertically on the
ground on a sunny day and measure its shadow, measure the shadow of the
skyscraper....."
"....and again ?...."
"walk up the stairs and use the barometer as a ruler to measure the
height of the walls in the stairwells."
"...One more try ?"
"Find where the janitor lives, knock on his door and say 'Please, Mr
Janitor, if I give you this nice Barometer, will you tell me the height
of this building ?"
