# Thread: don't laugh !!!!!!!!!!!!! :-)

1. a very clever question shsnawada!

in simple physics ... get some wood .. dip that in a beaker full to brim with water ... measure the volume of displaced water .. that would be volume of the wood .. now let it dry and ...put it on scales .. take exact reading! ..
put a glass dome over the wood covering it .. leave a whole for oxygen at the bottom of the sphere .. and yes to determine the volume of the glass dome ..(4/6 pi.r^3)
.. now light the wood .. note down the EXACT reading on teh scale at a particular instant and quickly kill the fire .. now weight theleft over wood with ashes ...

density of fire (approx) should be(in Kg/m^3) = (((mass of wood (unburnt) - (weight of wood +ashes) - reading on scale while wood was burning))/9.8)/ (volume of dome - volume of wood)

i think it should work .. but then again .. i could have missed something ..

Sounds convincing. Reps for this (i couldnt think of anything of this sort).
Basically the whole problem lies in my brain which tends to get a bit strange and starts asking all this wierdo questions like: Is the outer bit of a flame denser than the inner bit? How could chemical reaction take place if the atoms are ionized (fire is plasma)? And do imaginary numbers exist in a 4 dimensional universe??.the list just goes on....

3. Fuk this thing which says i have to spread reps to more people....

4. nevamind the reps ...
that imaginary number thingie ... can complex plane exist in 4d? .. i dun think so ... but does even 4d exist? (not considering the time-space dimension .. i think it ahs no proper mathematical credibility)
and majority of chemical reactions do take place due to ionisation! .. like dissolving salt in water ... etc.
the dual density of fire ... now thats a again a good question . but i dun have any idea how you would determine that ...

I've heard that sqrt of -1 has a fourth co-ordinate.. That means it would work in a 4 d (spatial, not time) world.. I came across this: http://tetraspace.alkaline.org/ . Its about the whole 4 d thing. Interesting read.

You mean, the chemical reaction takes place in the "end" of the flame.

I think another guy is going to say that this is a guitar tab forum but fuk that, a mod is on our side..

8. yes but it can only exist in a complex plane ... the iota (or sq root of -1) can exist in "n" number of dimensions .. but only in complex form ... the hypothetical universe that you are talking about may not be compatible with a 4d+ complex planes ...
by the way very fascinating link .. this should keep me buys for a while thanks

no simply .. the common chemical reactions like dissolving salt in water occurs due to the ionisation ..
i dunno in which context you are talking about the ionisation ..
and yeah .. dun take anything that i say for granted .. i am only an A-level student so i might be wrong

10. Ahhh...now it makes sense. And about the link: If you get the idea of a 4th dimension, you're thinking wont be the same again. It's like lets say looking at tool's (lateralus) lyrics.

11. hehe .... ^ that lateralus thingy made me smile ...

12. Lateralus is just saying: It seems to makes sense but remains obscure....in one word.

Joke was indeed hilarious..and i wonder how dim witted people can be to not get such a simple joke

nice 'un!

ON THEIR RETURN THE TYRE OF THEIR CAR BURST AND THEY HAD TO PUSH THE
CAR ALL THE WAY BACK AND THAT THEY WERE IN NO CONDITION TO APPEAR FOR
THE TEST.

SO THE DEAN SAID THEY CAN HAVE THE RETEST AFTER 3 DAYS.THEY SAID THEY WILL
BE READY BY THAT TIME. ON THE THIRD DAY THEY APPEARED BEFORE THE DEAN.THE
DEAN SAID THAT THIS WAS A SPECIAL CONDITION TE ST. ALL FOUR WERE REQUIRED
TO SIT IN SEPARATE CLASSROOMS FOR THE TEST. THEY ALL AGREED AS THEY HAD
PREPARED WELL IN THE LAST THREE DAYS.

THE TEST CONSISTED OF 2 QUESTIONS WITH TOTAL OF 100 MARKS.

Q .1. WRITE DOWN YOUR NAMES -----( 2 MARKS )
Q.2. WHICH TYRE BURST -------( 98 MARKS ).
