20 To Watch

Today I'm being honored by the good folks at the National School Boards Association at their annual Technology + Learning conference. They've named me as one of their '20 To Watch' for 2007. The 20 To Watch list started last year and is intended to identify 'emerging voices that will shape the future of education technology.' Other recipients this year include Karl Fisch, Gary Stager, and Erin Reilly (who I met earlier this year at the Leaders in Learning awards).


Unfortunately I won't be able to attend the awards ceremony in Nashville, but I appreciate the recognition of the work I'm doing here at CASTLE. Thanks, NSBA!

Why are so many objects in space shaped like discs?

It's one of the most consistent patterns in the unviverse. What causes it?

  • Spinning discs are everywhere – just look at our solar system, the rings of Saturn, and all the spiral galaxies in the universe.
  • Spinning discs are the result of two things: The force of gravity and a phenomenon in physics called the conservation of angular momentum.
  • Gravity brings matter together; the closer the matter gets, the more it accelerates – much like an ice skater who spins faster and faster the closer their arms get to their body. Then, this spinning cloud collapses due to up and down and diagonal collisions that cancel each other out until the only motion they have in common is the spin – and voila: A flat disc.

This is the best (and simplest) world map of religions

Both panoramic and detailed, this infographic manages to show both the size and distribution of world religions.
