PBS Space Time: Epic Explanations of the OMG Particle, GZK Limit, Cherenkov Radiation, and More!
Fantastic episode from PBS Space Time that focuses on the Oh My God particle, and in doing so also highlights and explains a bunch of other discoveries and discovery facilities that make cosmic rays such a fascinating avenue of exploration for scientists!
Cosmic rays aren’t actually rays at all, but atomic nuclei traveling at close to the speed of light. Typically they are low in energy and are easily deflected by other particles, but on rare occasions an incredibly powerful atomic nuclei strikes the Earth’s surface. The largest of these was the Oh My God Particle.
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.
