The processing of gold: A diary entry
April 5/2018
I am the worlds most precious metal.
I am worth more than any silly diamond, and far more stronger than Iron. No one can come close to being as important as I.
I start as a tiny mineral, found underground where I spend my days perfecting myself. Most might find relatives of mine in water, buried among sand and dirt. Then we are put through the most rigorous of training until we are god.
Well, gold, but you know what I mean.
Once I am perfection, I will be sold among the masses of people. I will be loved my all and crafted into everything. If I wanted, I could take over the world...a world of just gold, wouldn't that be magical?
Today I think I will be made into a ring, I hope I am not squeezed on some fat woman's finger.
I hope this helps a little, Cheers :)
Mechanical mouse has a ball that turns rollers inside. If friction is lost between the ball and the mousing surface, or between the ball and the rollers, the mouse fails to work. In order to assure good contact with the mousing surface, the ball must be fairly heavy. When you change directions with the mouse, you must make the ball change rolling directions--an action that inertia likes to prevent.
An optical mouse makes use of an LED and some optics to detect surface texture and the changes in it as the mouse is moved. There are no moving parts
