Have you ever wondered what the official SI unit for magnetic field strength is (hint: ampere per metre), or maybe kinematic viscosity (square metre per second), or perhaps the correct abbreviations or symbols for some specific SI unit or value? The Bible of SI Units, The International System of Units, 8th Edition, has all the (very official) answers and can be downloaded in PDF format in English or French from the website of the Bureau International des Poids et Mesures. It’s actually just kind of find reading through one of the most important changes in recent scientific history, but it’s particularly useful in a world where there is still a lot of confusion over which units and scale are appropriate to use and when, and how to properly cite them!
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.
