Physicists at the National Institute of Standards and Technology (NIST) have built the most precise atomic clock in the world.
In a new study published in Physical Review Letters, the researchers say that their new clock’s uncertainty is 9.4×10-19. That incredibly small uncertainty means that it won’t gain or lose a second in 33 billion years, or two and a half times the estimated age of the universe. This makes it the most accurate atomic clock ever made.
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.
