Paradigms is a pilot for a new show about how we know what we know, produced in collaboration with MinuteEarth (http://youtube.com/minuteearth), Veritasium (http://youtube.com/veritasium), and Aatish Bhatia. The first episode is about the science of seeing, from the extramission theories of the ancient Greeks (like Plato and Euclid and Galen) to the Islamic scientist Ibn al-Haytham (Alhazen) who studied the optics of pinhole chambers and images, to Johannes Kepler who understood the role lenses play in vision, to the modern era where we now know that the brain plays a huge role in seeing & processing images from the eyes, too!
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.
