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.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
