"The Daily Overview project was inspired, and derives its name, from an idea known as the Overview Effect. This term refers to the sensation astronauts have when given the opportunity to look down and view the Earth as a whole. They have the chance to appreciate our home in its entirety, to reflect on its beauty and its fragility all at once. That’s the cognitive shift that we hope to inspire."

In mathematics, a Fourier series (English pronunciation: /ˈfɔərieɪ/) is a way to represent a wave-like function as a combination of simple sine waves. More formally, it decomposes any periodic function or periodic signal into the sum of a (possibly infinite) set of simple oscillating functions, namely sines and cosines (or complex exponentials)

The brothers and sisters of the innocuous ants found roaming in most of our backyards host a plethora of strange and wacky characteristics.

Here are some interesting facts about the coolest ants in the animal kingdom (paired with corroborating images): http://goo.gl/dnkAoZ
