great-tree-of-lifeTeachable Moment: Wonderful visual representation of evolution and tree of life and how we're all related, way, way, way, back.

This Great Tree of Life diagram is based primarily on the evolutionary relationships so wonderfully related in Dr. Richard Dawkins'The Ancestor's Tale. Some secondary branching relationships and ages of common ancestors were gleaned from university and other scholarly websites as well as scientific journals. The smallest branches are purely illustrative; they are intended to suggest the effect of mass extinctions on diversity, and, on a few of the branches, changes in diversity through time. This tree of life diagram is NOT intended to be used as a scholarly reference tool or as a complete picture of life history (only a very few extinct main branches are shown, for example). Instead, it tries mainly to illustrate a great lesson of evolution; that we are related not only to every living thing, but also to every thing that ever lived.

Teachable Moment: Elegant visual illustrates counting by 10s and provides a great comparison of the life spans of mammals, reptiles and birds.

Taken from the book The Transformer: Principles of Making Isotype Charts this simple clean graphic illustrates average life spans of various animals.

Teachable Moment: This map really drives home the point that our consumption exceeds our capacity.

Today humanity uses the equivalent of 1.51 planets to provide the resources we use and absorb our waste. This means it now takes the Earth one year and five months to regenerate what we use in a year (Global Footprint Network 2010).

What is Biocapacity?

Biocapacity is shorthand for biological capacity, which is the ability of an ecosystem to produce useful biological materials and to absorb wastes generated by humans.

mathematical-impressionsSince the 1970s, Fomenko has produced more than 280 illustrations, 84 of which — 61 black-and-white and 23 color — are collected in this remarkable anthology. Alongside the images are Fomenko’s original captions, illuminating both the inspiration for the artwork and the historical subtexts for it.

Thanks to the people at Good Morning Silicon Valley for pointing this one out.

Teachable Moment: Lets face it, turning a piece of two sided paper into an object with only one side really is magic... and this is a great cartoon to drive home that point.  And the cutting the strip to end up with two linked rings is a pretty cook trick as well.
