Randall Munroe of xkcd fame has an awesome piece in the New Yorker called The Space Doctor’s Big Idea. It reads a bit like a children’s book explaining Einstein’s theory of special and general relativity in normal language. The illustrations are top notch too–check it out!
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
