Amazing Airport Model

This model airport is totally amazing. The detail is incredible. But the takeoffs and landings are even more impressive!

Exploring the Pythagorean Theorem

Sal Khan from Khan Academy goes through several proofs of the Pythagorean theorem. What I particularly love about all of these is how geometric and visual they are. It might even be possible to do Bhaskara’s proof with a couple of squares of paper and some scissors, making it accessible to little kids with no […]

Curiosity Mission

I watched the landing of the newest Mars rover Curiosity last night. It was fun being a part—if just an observer—of this event, and I was moved not only by the accomplishment (amazing!), but by the emotion in the room. It will be exciting to see how this mission unfolds over the next 2+ years. […]

I’d heard of the Solar Dynamics Observatory (SDO), but it wasn’t until the Transit of Venus in June that I realized just how amazing were the publicly available resources NASA has provided.

Hair Makes Everything More Wonderful

Really not entirely sure how I feel about this. Sure, they’re amazing. But I’m glad I’m not eating anything prepared in this kitchen!! http://people.hws.edu/chin/ChristineChinWebsite/SentientKitchen/index.html

Interesting Educational Sites

The first, which is quickly becoming famous is Salman Khan’s http://khanacademy.org, which extensively uses YouTube to provide what he calls “asynchronous learning”. Over two thousand videos covering a wide array of subjects, with particular strength in math, economics, and science. He also has over 60 videos on astronomy and cosmology. At about ten minutes each, […]
