Daniel Tosh: Blaming the Amish

Am I the only person who blames global warming entirely on the Amish? Are they not a constant reminder of how awful life would be without all this great technology? Every time I want to cut back and conserve on natural resources, I just look at the Amish and I'm like, 'F**k that.'

William Ferrel

Died 18 Sep 1891 at age 74 (born 29 Jan 1817).American meteorologist who was an important contributor to the understanding of oceanic and atmospheric circulation. He was able to show the interrelation of the various forces upon the Earth's surface, such as gravity, rotation and friction. Ferrel was first to mathematically demonstrate the influence of the Earth's rotation on the presence of high and low pressure belts encircling the Earth, and on the deflection of air and water currents. The latter was a derivative of the effect theorized by Gustave de Coriolis in 1835, and became known as Ferrel's law. Ferrel also considered the effect that the gravitational pull of the Sun and Moon might have on the Earth's rotation and concluded (without proof, but correctly) that the Earth's axis wobbles a bit.
