Have a very happy, 71st birthday, Stephen W. Hawkings.
On January 7th 1930, the last naturally discovered element and heaviest alkali element, Fr (francium), was discovered by Marguerite Catherine Perey, a French chemist working in Marie Curie’s lab at the Institut du Radium in Paris. She later went on to become the first woman to be admitted to the French Academy of Sciences and head nuclear chemistry research at the University of Strasbourg.
The “father of standard time” Sir Sandford Fleming, the man who first divided the world into time zones, was born 186 years ago yesterday. Fleming was the leading train engineer of his day and first created a time zone map to solve the problem of train scheduling. How’s that for a paradigm shift to fix your logistics problems? On the side, he also designed Canada’s first postage stamp, featuring a beaver. What can’t this man do?
Here in New York City in 1790, in his State of the Union address, President George Washington urged Congress to support the passage of patent law, arguing that patents contribute to a free society and government by promoting free discourse of ideas and enquiry and inadvertently created the DIY movement 200-odd years later.

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.
