There’s an interesting back-and-forth going on for a few months now, panning out in online letters and published articles in Scientific American. Beginning back in February with “Pop Goes the Universe” by Anna Ijjas, Paul J. Steinhardt, Abraham Loeb, essentially arguing against inflation theory. A number of opponents to that article – 33 in fact – responded in kind with their own Scientific American article, here. The original trio of authors (those of the “Pop” article) then offered their own follow-up rebuttal, and further FAQ explanation of their thinking. Fascinating stuff!
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.
