If you buy a new light fitting.............

[craft1948]

which needs 5 light bulbs, and you put in 5 light bulbs from the same box......................why don't all the light bulbs stop working at the same time?

[pericat]

are you afraid to go to science with this craft - I would be

[Postdog]

Dunno, but next time this happens, get all your mates round and all wave your hands at the light. Many hands make light work appaerently.

groan ^

I can always bring science to CB!

For the same reason that if you set two cigarettes burning the smoke doesn't form exactly the same pattern.

Tiny variations in something can produce large scale differences in their effects. It's called Chaos theory or non-linear dynamics to the mathematicians that think "chaos theory" sounds a bit too popularist

[pericat]

That sounds much better than my 'because it does' theory jake

''It's called Chaos theory or non-linear dynamics to the mathematicians that think "chaos theory" sounds a bit too popularist''

Damn... j-t-p just beat me to it...

[craft1948]

thanks guys I knew I could rely on you............so you're saying 3 of them were okay and the other 2 were shit......

[snags]

In layman's terms... yes...

[craft1948]

so is this non-linear dynamics something that just can't be explained?

[snags]

Just go and buy two more bulbs and forget the non-linear dynamics...

[AndThenSome]

Or take out a loan so that she can go college and then university so we can all be involved for this Quest for the mysterious scientific truth....

[craft1948]

I just asked if some things ie chaos was unexplainable..............I don't think I'll bother with uni ATS.....my proper job was.................engineering pmsl......

[AndThenSome]

Craft i actually had you down as a brain surgeon moonlighting as a rocket scientist!

[craft1948]

gee thanks ATS :-)

[logic]

why the groan PERI i thought that was witty.

[ummmm]

It made me laugh :-)

[dothawkes31]

it also depends on whether someone in the room above jumps on the floor directly above the light fitting or just to one side, the vibration might not reach all the bulbs with the same impact
