Math is all around us. While we all have complained at sometime “when are we going to use this?” (or at least heard it from students) the fact is that math how we are able to understand and define the universe around us. Today’s infographic looks at ten mathematical equations from history that have fundamentally changed how we see the world. [VIA]
When are we going to use this? Why do we learn this? How much math is really out there? This interesting map of mathematics was created to show just how wide reaching and diverse the field of mathematics really can be. From learning to count to simple arithmetic into more advanced areas like calculus and differential geometry to practical applications like statistics, game theory and even economics, this chart has it all. Make sure to check out the wonderful video explaining it all, linked below. [VIA]
From the Numberphile YouTube Channel, this video looks at statistics, probability, and game theory as well as human behavior to provide you an almost(?) unbeatable strategy for winning at Rock-Paper-Scissors. (No mention about Lizard & Spock)

We all love our four (and two) legged furry (and feathered) friends. Some people even love no legged, scaly friends! Have you ever really thought of how much it costs to keep our pets their healthiest and happiest each year, however? Today’s infographic calculates the average annual costs for various household pets including several sizes of dogs, cats, birds, and reptiles. This would be an excellent study in class about budgeting and calculating averages as a compare/contrast activity. [VIA]
“In this print, Escher uses two-dimensional images to depict objects free of the confines of the three-dimensional world. The image is of a rectangular three-story building. The upper two floors are open at the sides with the top floor and roof supported by pillars. From the viewer’s perspective, all the pillars on the middle floor are the same size at both the front and back, but the pillars at the back are set higher. The viewer also sees by the corners of the top floor that it is at a different angle than the rest of the structure. All these elements make it possible for all the pillars on the middle floor to stand at right angles, yet the pillars at the front support the back side of the top floor while the pillars at the back support the front side. This paradox also allows a ladder to extend from the inside of the middle floor to the outside of the top floor.” (Wikipedia)
