I hope you got a chance to watch the Falcon Heavy test launch by SpaceX earlier this week either live or afterwards. If you didn’t, grab your popcorn and fire up this video. I watched it live at work and it was quite a thrill to watch the biggest rocket since the Saturn project lift off and then see the two boosters land simultaneously back on earth. Unfortunately the main booster didn’t land successfully back on the floating platform (not in the video), but two out of three isn’t bad. Since this was a simple test flight, Elon loaded his personal Tesla Roadster into the rocket for weight (generally companies just use heavy chunks of metal, etc) and there was a subsequent live stream of the car floating through the solar system.
I love the videos about the science behind games at the fair, but Mark Rober’s video was the first time I’d seen the same formula applied to an arcade. it taught me something about the rainbow circle game that will change my life forever.
And everyone’s favorite woodworking geek, Matthias Wandel, posted a video showing how you can use a free app on your phone or tablet to measure the RPM of your shop tools.
