If this could be done fairly cheaply, diamond would become a hugely important engineering material. Diamond would be an immensely strong structural material, for example, enabling the construction of much higher skyscrapers and longer bridges than current ones. Diamond might also be used for applications such as turbine blades, although the low toughness of diamond would need to be overcome. As the toughness of a diamond sample varies depending on the orientation of the sample, it may be possible to make high-toughness components from a diamond-based material (perhaps by having many thin layers of diamond, with each layer having a different crystal orientation to adjacent layers).

And become Zero Visibilty for Fishes and Sharks thereafter given that it is a bright sunny afternoon or it is a full-moon day apart from it being a clear sky.
And what do they do for light after that point? Do they stay put weherever they are ?
Or try to move and swim in the dark too, and in the process, accidentally collide head-on each other and 'injure' themselves?
Or do they have some natural mechanism in their eyes (like Cats have: I think so about cats)to see in dark too (Zero visibilty to noramal human eyes) and manage to wander as freely as they 'like'?

I do a experiment of shampoo dilution.I test the pure shampoo pH,then record the value. after that,I diluted the shampoo with distill water then i test the pH,I continue the step with adding more distill water.

What is the result i can get? the pH of shampoo ll increase or decrease.
Why you choose the answer ,explain.

Plz help me slove the question.Do anyone do the experiment before?

String theory predicted ten dimensions, but as it got more and more complicated (five theories instead of one), it became clear that what was really need to unify them was eleven dimensions, which had been predicted by another theory, quantum gravity. However, now that both have evolved into M-Theory, that brings me to a basic unanswered question. Is M-Theory really a "unified field theory?" Does it bring gravity into the equation by invoking that extra dimension? If so, how does it unify the electroweak, strong and electromagnetic forces with gravity? I've never heard a simple explanation that didn't require a Ph.D. in Physics.

The Soviet/Russian academic S. Vavilov suggested an
interesting idea. In his book 'Isaac Newton' he wrote.
The force, according to the Newton,s Second Law,
is equal to : F= ma.
This force is possible to consider as absolute independent
quantity - impulse. When in case with light quanta
the impulse is equal to: mc.
He continued.
Let us now imagine that light quanta falls on a black body,
and it absolutely absorbs this light quanta
( it means light quanta stops).
Then, according to the Lebedev,s law, light quanta
renders pressure on the black body: E/c.
Therefore it is possible to write: mc=E/c.
It means that according to Classic physics the stopping
light quanta has rest mass: M=E/c^2. (E=Mc^2).
=========================
What is your opinion?
