This interactive info-graphic is very well done!
 
In 2014, in the states of Colorado, Utah, Virginia and Washington, the most common job was software programmer. 
The jobs picture has changed profoundly since the 1970s. This map shows how those changes played out across the country.

Can you believe the cost of these books?  
College textbook publishers charge so much because they can get away with it.

It's that time of year when some trigonometry help might be in order.  Here is my free trig website... any suggestions or comments are always welcome and appreciated. 

NEW: Printable calculus fact sheets in the Calculus section.  And always fun trig memes: http://www.trigcheatsheet.com/2014/05/trigonometry-memes.html

This is really nice... I had to share it out.
 
Catenary

A rope is supported at its ends. What shape do you think it assumes?
Galileo, some 400 years ago, thought a parabola (red, thin line). He was wrong: the right answer is a so-called catenary (black), which, however, resembles a parabola quite well!

The curve a hanging flexible wire or chain assumes when supported at its ends and acted upon by a uniform gravitational force. The word catenary is derived from the Latin word for "chain". In 1669, Jungius disproved Galileo's claim that the curve of a chain hanging under gravity would be a parabola.
The curve is also called the alysoid and chainette. The equation was obtained by Leibniz, Huygens, and Johann Bernoulli in 1691 in response to a challenge by Jakob Bernoulli.

Huygens was the first to use the term catenary in a letter to Leibniz in 1690, and David Gregory wrote a treatise on the catenary in 1690. If you roll a parabola along a straight line, its focus traces out a catenary.
As proved by Euler in 1744, the catenary is also the curve which, when rotated, gives the surface of minimum surface area (the catenoid) for the given bounding circle.
