Is water polymer or monomer?
What's the meaning of polymer or monomer?
Does monomer just mean a single molecule of an element?
like O-H-O

And polymer means lots of those "single molecule"? like:
with lots of O-H-O joined together?

Please answer it as simple as possible. THanks :)

Magnetic North pole lies where Geographic South pole does(16 degrees I guess) and vice-versa... Then why is it said that one must not sleep with head pointing towards North? It should be South??????????

Dear All,

How can I calculate how much energy converted from Solar Energy to Electricity? Does it based on the how strong of the sunlight? Does it based on how many solar cell? Any detail equations for this purpose?

Thanks a lot.

Holly

In the Neutralisation experiment, the burette in the experiment is always filled with acid, and the alkali is always filled inthe conical flask below the burette. Why do we want to do so?

Perhaps they partially exist on a nearby plane of deep gravity that does not directly interact with our universe. That would mean that gravity has much longer range than previously assumed. Maybe the force they emit as "dark energy" is not congruous with normal matter.

Such a revelation whould show that we really don't understand gravity...

I heard that perhaps "dark matter does not interact" with normal matter. But couldn't it still come from stars and galaxies? Perhaps it is emanating into another dimension from the stars...

The main idea here is that the star is like the tip of the iceberg with dark matter/energy below in the depths (the rest of the iceberg) beyond the reach of normal space...

I really enjoyed reading wikipedia's articles on M-Theory. Now I want to understand a little more about how the p-branes operate, for example, what happens when p-branes collide? Do p-branes exert forces on other p-branes from a distance, or do they have to collide in order to change their movement? Are there any good internet resources I should look at?
