    Going Pro!

    I’m sure that you’ve all seen those crazy videos on YouTube of dogs being left alone in their homes with a GoPro camera attached to them. They invariably end up getting into all kinds of mischief while their owners are away. And of course, the dog gives a, “I didn’t do it…” look that always melts their humans’ hearts.

So was borne the idea of a high resolution, incredibly compact, and easy‐to‐use camera that could go anywhere and take any kind of action shot—and eventually action video. Not only have GoPro’s have been put on mischievous dogs but they’ve been everywhere from attached to flying drones getting impossible aerial shots (now used in motion picture productions), to spelunking and sky diving, and even into space—as one little girl did a few years ago onboard a Hello Kitty‐crewed rocket (see the Best of them All vid to the right)! This company has grown incredibly fast since 2002 and sports a huge line of products that have literally transformed the digital photography and videography landscapes!

    Two Geometry Brainteasers!

    When writing fun stuff for my company’s global communications site, sometimes I like to throw in a brainteaser every now and again—especially given that a lot of PTC’s employees and customers are engineers. So here are two geometry puzzles to get those old mental juices flowing! 64 = 65 Geometry Paradox Where does the hole in second triangle come from (the partitions are the same)? Write Numbers Write the numbers from 1 to 8 into the squares, so that the squares with consecutive numbers do not touch (neither edges nor corners). These and other amazing geometry puzzles can be found here on BrianDen.com.
