A group of researchers has created a clock that, with some tweaks, could be four to five times more precise than the world’s best clocks. To put that into perspective, if today’s most precise clocks started ticking at the birth of the universe, they would be off by only half a second today; with more improvements, this new clock has the potential to be off by only 0.1 second.
“Atomic clocks are by far the most precise instruments mankind has ever made by many orders of magnitude,” said Vladan Vuletić, a professor of physics at MIT and senior author of a recent paper describing the work. Now, “we are pushing this boundary” further, he added.

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.
