Lest We Forget: Why We Had A Financial Crisis. When a true genius appears in the world you may know him by this infallible sign, that the dunces are all in confederacy against him. It is clear to anyone who has studied the financial crisis of 2008 that the private sectorâs drive for short-term profit was behind it.
Diamonds are made out of carbon â highly organized carbon, that is. Geologists are still guessing how diamonds formed in the Earth from 1 billion to 3 billion years ago, according to a recent study in the journal Nature, but they think the recipe follows something like this: 1. Bury carbon dioxide 100 miles into Earth. 2.
Technically, a diamond is an allotrope, or a form, of the element carbon (a diamond is actually carbon in its most concentrated form). Within a diamond, the carbon atoms are arranged in a variation of the face-centered cubic crystal structure called a diamond lattice. This arrangement of carbon atoms essentially means that the diamond expands outward at the same rate in all directions during its initial growth. Because of its structure, which is extremely rigid, a diamond can be contaminated by very few impurities, such as the elements boron or nitrogen. Combined with its tendency to be transparent, this results in the colorless, clear appearance of most diamonds.
