I bought shrimp from supermarket, mince it up, add DI water, spin it down, remove the spuernatant and test the supernatant with Schiff reagent. The supernatant turn pink then purple. Is it because there is formaldehyde (or any aldehyde) in shrimp? or it is something else? Does any one know what chemical is used as preservative in seafood industries?

A Scalar (ex: mass) has a magnitude but not a direction.
A Vector (ex: velocity) has both a magnitude and a direction.
Can you give any examples of quantities that have a direction but not a magnitude? Are these still called vectors or is there another term for them?

Some dummies at school say it's 5. Well, 5 times 5 is not 3.1415926....., right?

Well, if pi is irrational, can there be a square root?

I have always been interested in the force of energy within magnets, along with alternative sources of energy. Well I surfed into this addy below. I found the information on free energy to be logical (with little knowledge of electricity). Also the amount of power produced from the size of the unit is hard for me to comprehend. Please view this link and, please reply. I'm interested in supplying my area with energy for less then 1/2 the cost.
Thanks
