I have this <1% label of one certain liquid in a solution. Does it mean there is more or less than 1% of that liquid? This is a simple question, but I just am not sure about the meaning...

My guess is that there is more than 1% of that liquid.

I'm looking for some sites on these things, preferably aimed at older high school kids, as well as new comers into scientific theory. All I could find was definitions of the terms, not the study themselves. So I pulled up a lot of "What is scientific theory" and not a lot of "The scientific theory of this or that is currently...."
Please help!!

Hi, Im doing my IGCSE design project ( electronics ) and im trying to make a mat which can be placed behind a radiator and will turn that heat into electricity, a) to reduce heat loss through the wall, and b) to save electricity and create some at the same time.

Unfortunatly I have no idea what to use in the mat to turn the heat into electricity. I've been researching Thermocouples ( http://www.rvmobile.com/TECH/TROUBLE/Tcouple.htm ) but i've no idea how much they are and how how small. Does anyone have any idea about what I could use in the mat. ( plaese dont make it a expensive idea, this is just a project. )
Thanks

We have all read about evolution, but how does something that is not living pop into existence having a fairly complex strand of DNA or RNA in it for no other purpose but being a transport device to infect another individual? Is it possible that they were created by someone?

I asked this in the CORRECT catorgory, but no answers. I know we've got some eager minds here that can answer my question.

I'm looking for the smallest FM receiver I can plug into my car and speakers deep into the smallest spot I can get to in order to hide it so it won't get stolen again.

I plan on using an Ipod only to play my music through an FM transmitter.

so, any idea on the small radio for my car?
products? suggestions?

The rocket ship can leave fuel at stations 1, 2, and 3. What is the minimum number of days required to reach Planet X from Earth?
