Validate the new Bank of Canada polymer bills by shining a laser pointer through the frosted maple leaf window. The window acts as a diffraction grating and will display the face value of the bill:
I’m itching to write a little about my recent trip to Cozumel, but I’m a bit bogged down by homework for the next few days. Even so, the homework in my Principles of Nanotechnology course overlaps with some interesting observations about geckos I made while in Mexico (that they can walk on walls and ceilings in various conditions), so I thought I’d share. Unfortunately, my camera broke, so you’ll have to do with a picture I took at the California Academy of Sciences. Anyway, the homework assignment is all about the nanotechnology of gecko feet, and what makes them stick. Hit the read more link for the rest of the goodies.
Here’s a quick test of Google’s Maps embedding functions. I work almost precisely at the latitude and longitude of: 53.5287626358291,-113.52613806724548, which corresponds to the map below.
