As of today, the Burj Dubai skyscraper in the Middle East stands at 650 meters. The construction has finally surpassed the current tallest man-made structure, the Warsawa radio mast in Poland, which stands at 646 meters. Only another 169 meters to go before the tip of the aircraft beacon is up! Wow a...lmost 800 meters tall! That's big
Around the sixth week of gestation, six swellings of tissue called the hillocks of Hiss arise around the area that will form the ear canal. These eventually coalesce to form the outer ear. Darwin's point, or tubercle, is a minor malformation of the junction of the fourth and fifth hillocks of Hiss. It is found in a substantial minority of people and takes the form of a cartilaginous node or bump on the rim of their outer ear, which is thought to be the vestige of a joint that allowed the top part of the ancestral ear to swivel or flop down over the opening to the ear.

A simple and beautiful mathematical curve known as a logarithmic spiral, a spiral whose separation grows in a geometric way with increasing distance from the center. Also known as the equiangular spiral, growth spiral, and Bernoulli's spiral or spira mirabilis. Nature and Math can be beautiful.
