I know know how colour gets into colour, becuase of the light reflection, but how do things know what frequency to reflect so we can see the colour?

Yes, Howard Stern talked about this before so I give him full credit. Sharks are useless and kill us. Why not kill all of them, at least the really bad ones: Great Whites, Bull Sharks, Tiger sharks. At least start with those. The liberal tree huggers will say "IT UPSETS NATURE'S BALANCE!!!" Screw nature's balance. I don't want my damned weenie bit off when I go swimming.

What i mean by this question is black and whites are shades of colours, but for an example, the colour blue, how does it turn blue, are there chemicals or something that react to make the colour.

Like peoples eye colour, the information is in our genes, but how does the colour get there, are their hormones that make the colour etc?

equation: f(x) = x^2 + 4 x >= 0
Domain: (0, oo)
Range: (4,oo)

equation: f^-1(x) = ( x - 4) ^ (1/2)
Domain: (4, oo)
Range: (0, oo)

Is this correct? Thanks for your help.

I've been trying to find information regarding the history of the equality symbol (=). The most I've been able to find after several days of searching is
"The equal symbol (=) was first used by Robert Recorde (c. 1510-1558) in 1557 in The Whetstone of Witte. He wrote, "I will sette as I doe often in woorke use, a paire of parralles, or Gemowe lines of one lengthe, thus : ==, bicause noe 2, thynges, can be moare equalle." Recorde used an elongated form of the present symbol."
Does anyone know something more informative (for example, how people showed equality before "=" was the equality symbol) or know of a web page where I could find such information?
