Why are diamonds so expensive?
Diamonds are actually carbon pieces that was subjected to intense pressure and heat far down in Earth’s interior. It takes a lot of time before the carbon is compacted and becomes the incredibly hard diamond.
Diamond are known as the hardest known natural substance on Earth. But before they become into the sparkly gems that we are familiar with, they must be first extracted from the earth, cleaned, cut and polished before they even get to the jewelers.
The ancient Romans are the ones responsible for the names we use for each of the twelve months of the year. During the olden times, March was the first month of the year while February was the last. The Roman calendar underwent several revisions and in 153 B.C., January become the first month of the year.
The fastest runner on earth is the cheetah. No other animal can outrun this feline’s 70-mile per hour speed. This jungle cat is three times faster than humans whose top speed is recorded at 25 miles per hour.
The oldest false teeth discovered was from the skeleton of a 4500 year old man found by archaeologists in Mexico. The scientists found that the ancient dentures were made of animal teeth and that the man’s front teeth appear to have been ground down in order to make room for the fake teeth. These findings provide evidence that false teeth have history much longer than previously suspected.
The tips of fingers and toes are covered by a tough, thick layer of skin (epidermis) with a lot of water-loving keratin. During a long bath or soaking in the pool for a long period of time, the keratin absorbs water making the outer layer of the epidermis swell. However, there is no room for this expansion which leads to “pruning” effect or wrinkles.
