Time Travel Tuesday #timetravel a look back at the Adafruit, maker, science, technology and engineering world
1790 – Patrick Matthew, Scottish originator of the first full and complete hypothesis of natural selection in 1831, is born.
Patrick Matthew was a Scottish landowner and fruit farmer, who contributed to understanding of horticulture, silviculture, and agriculture in general, with a focus on maintaining the British navy and feeding new colonies. He published the basic concept of natural selection as a mechanism of evolution in an obscure appendix to his 1831 book On Naval Timber and Arboriculture.
Matthew failed to develop or publicise his ideas concerning natural selection; Charles Darwin and Alfred Russel Wallace were credited with publishing the theory of evolution by natural selection in 1858; and historical analysis shows no firm evidence that either Darwin or Wallace encountered Matthew’s earlier work before he contacted them in 1860. Darwin then publicly acknowledged that Matthew’s brief statement in the appendix had anticipated by many years the principle of natural selection in On the Origin of Species.
1891 – James Chadwick, English physicist and academic, Nobel Prize laureate, is born.
Sir James Chadwick, CH, FRS was an English physicist who was awarded the 1935 Nobel Prize in Physics for his discovery of the neutron in 1932. In 1941, he wrote the final draft of the MAUD Report, which inspired the U.S. government to begin serious atomic bomb research efforts. He was the head of the British team that worked on the Manhattan Project during the Second World War. He was knighted in England in 1945 for his achievements in physics.
Christiane Nüsslein-Volhard is a German biologist. She won the Albert Lasker Award for Basic Medical Research in 1991 and the Nobel Prize in Physiology or Medicine in 1995, together with Eric Wieschaus and Edward B. Lewis, for their research on the genetic control of embryonic development. Today she lives in Bebenhausen, Germany.
Adafruit now has WISH LISTS! For your shopping pleasure! This means you can add things to a “wish list” and then send it to someone else (or yourself) and that person, or you can add ALL the items to cart and buy them!
Over the last year or so many customers, students, hacker spaces and more told us what type of features they’ve wanted in a wish list and we’re please to launch this before the holiday season!
Adafruit publishes a wide range of writing and video content, including interviews and reporting on the maker market and the wider technology world. Our standards page is intended as a guide to best practices that Adafruit uses, as well as an outline of the ethical standards Adafruit aspires to. While Adafruit is not an independent journalistic institution, Adafruit strives to be a fair, informative, and positive voice within the community – check it out here: adafruit.com/editorialstandards
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.
Have an amazing project to share? The Electronics Show and Tell is every Wednesday at 7pm ET! To join, head over to YouTube and check out the show’s live chat – we’ll post the link there.
