Here is Bernard H. Porter’s 1939 map of Physics as a continent. via The Quantum Pontiff:
Thomas B. Greenslade, emeritus physics professor at Kenyon College in Gambier, Ohio, USA, has amassed (both physically and virtually) a fascinating and expertly curated collection of old physics teaching equipment. Among my favorite items are Bernard H. Porter’s 1939 map depicting Physics as a continent, with rivers corresponding to its principal branches.
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.
