Temperature tends to be relative — the air is below freezing, her fever is above normal. But scientists probe the extreme ends of the spectrum of what’s called absolute temperature: At the upper limit, absolute hot is a theoretical furnace where the laws of physics melt away. On the flip side, absolute zero — cold so cold there’s nowhere to go but up — is almost within scientists’ grasp.
To understand it, you first need some Physics 101. The atoms that make up matter are always moving. Temperature measures those atoms’ kinetic energy, or energy of motion. The faster they move, the higher their temperature. Absolute zero, though, is almost perfect stillness.
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.
