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.

Honshu Tsunami PropagationTeachable Moment: Great video using the NOAA MOST Model.

The MOST (Method of Splitting Tsunami) model, developed by Titov of PMEL and Synolakis of University of Southern California, is the standard model used at the NCTR. MOST is a suite of numerical simulation codes capable of simulating three processes of tsunami evolution: earthquake, transoceanic propagation, and inundation of dry land.

Teachable Moment: It's fun to see how much his mind wandered and the breadth of his interests.

Go to the Library of Congress for the full sketchbooks

The Atlantic Article has a great selection of images from the sketchbooks.

From the Atlantic Article:

It was on March 10, 1876 that Alexander Graham Bell made the first successful telephone call. "'Mr. Watson--come here--I want to see you," he said to his assistant, who was in the next room. Bell recorded those early telephone experiments in his lab notebooks from the time, as he did with countless other experiments and ideas.

Lego Antikythera MechanismTeachable Moment: It's easy to dismiss this as "I guess some people will try to build anything with Lego" but it highlights how simple building blocks (OK... it uses some differential gears which aren't that "simple") when properly and cleverly combined can make complex computations.
