Help! I'm more than 1,292,976,000 seconds old!

I feel ancient after visiting GirlsGoTech, an online math, science, and technology outreach program from the Girl Scouts. You can learn about careers in science, html code and the Internet (and find out how many seconds old you are!), try cryptic codes, make your own mandala (and learn about mathematics and symmetry), discover how your brain processes information, and compose digital music.

The GirlsGoTech Mandala Maker reminded me of Make-A-Flake (although it took me a bit longer to learn to use the Mandala Maker). What do you think of my mandala?


With either of these programs, you will create a design with several lines of symmetry. Can you see where the lines of symmetry are on this design? How can you fold this circle in half so that both sides have an identical pattern?

Flying cars

Want your own personal flying car? Get your driver's and pilot's licenses -- and $10,000 deposit -- ready and head on over to Terrafugia. Their "roadable aircraft" is set to roll off the assembly line in 2011. The prototype hit the skies on March 5, 2009 for a test run. The company claims that the wings can fold up in less than 30 seconds! In car mode, the company says the vehicle can get 30 miles per gallon and can go up to 65 miles per hour. The full purchase price is expected to range around $200,000 (US).
