still not satisfied
Young modulus does not tell about the elasticity of substance >>>
But it states the stiffness which means rigid , inflexible and hard to bend . of matter. & you represented the values of stiffness of rubber and steel such are Rubber = .1 - .01 GPa Steel = 200 GPa so in your point of view diamond is more elastic than both of them ... whose value is Diamond = 1220 GPa |

Elasticity is a measure of how well a material returns to its original shape and size i.e. it is the ratio of stress over strain. It does not mean how 'flexible' a substance is or how much it can be stretched. And the Young's Modulus measures the resistance of a material to elastic (recoverable) deformation under load. So keeping in view the definition of elasticity, we can say that Diamond is more elastic than both of them, i.e. it has more ability to resist the elastic deformation and return to its original shape.

Elasticity = The ability of a solid to return to its original shape or form after being subject to strain.
i do not know its measurement you are only talking about theoretical .. just give me one practical example? well in my mind still gobs of questions arise ... a interesting one :P so why don't we use steel in our trousers or make a world most expensive trouser by using Diamond ? "Elasticity is a measure of responsiveness. The responsiveness of behavior measured by variable Z to a change in environment variable Y is the change in Z observed in response to a change in Y. Specifically, this approximation is common: elasticity = (percentage change in Z) / (percentage change in Y) The smaller the percentage change in Y is practical, the better the measure is and the closer it is to the intended theoretically perfect measure."

that is why you are seeing difference between theory and practice. go through the definition of elasticity again, It's nothing what you think it practically is.

which is not the part of the darwinism.... it is the inhertance of the acquired characters the theory of the inhertance of acquired characters was given by lamarck

Q. 8. v. Why has pasteurized milk more nutrition than ordinary boiled milk?
All milk on the market unless labelled "raw" is pasteurized. I don't believe there is boiled milk on the market. The pasteurization process however, heats the milk up to 161 degrees for about 15 seconds by squeezing it through hot pipes. |

ordinary boild milk boiled at 100 celcius which lose
ordinary boild milk boiled at 100 celcius which lose many vitamins and protein while the pasturise milk at 72 celcius (confirm plz) for 15 seconds so it have much more preserved vit. than the other.
