Add some ice cubes to a pan on the stove. Within minutes, you will have observed the three most common phases of matter: solid, liquid, and gas. But at the extreme of nature’s limits, such as close to absolute zero (−273° C), the same matter enters strange and wonderful new phases.
The 2016 Nobel Prize in physics was awarded to three researchers whose work transformed our understanding of matter in such exotic states. David Thouless of the University of Washington, Duncan Haldane of Princeton University, and Michael Kosterlitz of Brown University took home the prize for, as the Nobel committee put it, “theoretical discoveries of topological phase transitions and topological phases of matter.”
Each Tuesday is EducationTuesday here at Adafruit! Be sure to check out our posts about educators and all things STEM. Adafruit supports our educators and loves to spread the good word about educational STEM innovations!
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, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, 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.
