The word "second" refers to the ordinal number two: second-rate, second-string, second period, second child, etc. Why was the word "second" used to name the smallest standard unit of time????

OK, I know that salt water boıls at a higher temperature than fresh water, so therefore fresh water boils quicker. What I want to know is, do they both increase in temperature at the same rate? If given the same heat and conditions, do they both increase in temperature at the same rate but then salt water raches its boiling point later? Or does one of them heat up faster before boiling? and why? why are the solutes changing the properties of the water? thanks

NO TIME WASTERS PLEASE
i am on my quest to create a perpetual motion machine
the critic says it cannot work but no one ever built a statue of a critic.

ive been thinking about this idea for a while now trying many various things and i feel i have invented a solution to do with pressure and electricity, perhaps you could think about this if your designing one

but has anyone else been or is trying to invent this system aswell?
do you have any tried and tested ideas?
do u have any ideas that might wor?

So, how do we do it? I was thinking I could stuff blankets or foam rubber around it's intake of air valve and this would over-heat it..
Is this possible, or is there a better way?

Hey,

Does anyone know how the compass in Google Earth is oriented? I assume it points to true north, and not to magnetic north for any given location--but I just wanted to double check. Thanks,

i thought people were enough smart for math, but they are not. i am just shock. But i just taught with students how to solve to math problems and they got it. that is weird. for example, some people do not like math. that does not make sense.

Is it just me or are Satellites getting bigger, or in a lower orbit?

Twice this week now, i have seen satellites that appear as a bright star, not quite as bright as the North Star though. They certainly were not planes, or meteors.

Has anyone else noticed this?
