I'm Dan and this is my blog. I'm a former high school math teacher and current head of teaching at Desmos. He / him. More here.


  1. All you have here is the output from Google Earth split across (as I recall) eight flatscreen monitors in portrait orientation. There was also a sweet multi-axis flight controller at the center.

  2. Wow, that’s slick. I remember way back in the day when MS Flight Simulator was where it was at. With this, though, people are always adding new things and always improving on it. I’m sure someday you will be able to walk into someone’s house and grab a coke. I’m sad I couldn’t see this first hand, thanks for sharing it!

  3. LOL.

    As a stats teacher, using the globe to demonstrate hypothesis testing is useful (maps work too, but with less “pop”).

    H0: Globe is 50% water

    Sample about 20-50 random points on globe with blindfolded spin. More dramatic than a random number generator sampling random spots on globe in google maps/google earth (while it loads in our slow connection) plus you get audience participation. Verify if sample results support hypothesis.

    That said, I wouldn’t mind getting a Holodeck.
