Adafruit is celebrating Lunar New Year🐍 Wednesday 1/29/2025. In combination with MLKDay, shipping could be delayed. Please allow extra time for your order to ship!
According to the study, published in Anthropocene on Monday, the particles could only have been forged in extreme heats above 3,300 degrees Fahrenheit. “Little Boy”—the Bomb America dropped on Hiroshima on August 6, 1945—vaporized the city, unleashed a fireball that reached 17 million degrees Fahrenheit.
Retired geologist Mario Wannier was sifting through the sand on a beach on Japan’s Motoujina Peninsula when he noticed the strange glass. Wannier’s trained eye can identify various minerals in a bucket of sand at sight—but the small glass beads he found puzzled him. “They are generally aerodynamic, glassy, rounded—these particles immediately reminded me of some [rounded] particles I had seen in sediment samples from the Cretaceous-Tertiary boundary,” Wannier said in an interview with UC Berkeley.
Adafruit publishes a wide range of writing and video content, including interviews and reporting on the maker market and the wider technology world. Our standards page is intended as a guide to best practices that Adafruit uses, as well as an outline of the ethical standards Adafruit aspires to. While Adafruit is not an independent journalistic institution, Adafruit strives to be a fair, informative, and positive voice within the community – check it out here: adafruit.com/editorialstandards
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.
