"An exact second..."

Say I wanted to make a clock and I have nothing to help me.

How would I go by defining an exact second? What is it? How do I time it?

It's got to be something with the way the Earth is divided into minutes and seconds but I just can't work out how it would be done...

It's doing my head in.

Help!

u forgot to square the baked bean molecule number

The number of grains of sand in the world multiplied by the molecules in a baked bean, divided by the subatomic biomass of spandau ballet.

There is actually a phusics definition for a second involving things falling in a vacuum over a fixed distance... etc..Ill not pretend to remember it so be happy with that

Weird ... I was thinking this just the other day. (I am you ... )

I think some guy just went "Oh, it's about ..... that long." And it was.
Yup.



Nope....

I think a 'second' is the amount of time for a beam of light from a part of the spectrum, say green, to travel through a vacuum which is x in lenth.

Get to it.

Or you may have meant a film like Bruce Almighty.

..mmm..


I meant a GOOD film

Phi11ip....


A cold drink, A slice of cheesecake and a god film.


Stop this nonsense as now i am thinking of it and it is now doing myy head in

How can you be sure that the amount of time is an exact second Niddle?

Count from one to ten.
