Katharine Burr Blodgett was an American scientific researcher. She was the first woman to be awarded a Ph.D. in physics from the University of Cambridge, in 1926. After receiving her master’s degree, she was hired by General Electric, where she invented low-reflectance “invisible” glass.
1907 – Gordon Kidd Teal, American engineer and inventor, is born.
Gordon Kidd Teal was an American engineer. He invented a method of applying the Czochralski method to produce extremely pure germanium single crystals used in making greatly improved transistors. He, together with Morgan Sparks invented a modification of the process that produced the configuration necessary for the fabrication of bipolar junction transistors. He is most remembered for developing the first silicon transistor while at Texas Instruments.
1927 – Fritz Lang’s futuristic film Metropolis is released in Germany.
Metropolis is a 1927 German expressionist epic science-fiction drama film directed by Fritz Lang. He and his wife, Thea von Harbou, wrote the silent film, which starred Gustav Fröhlich, Brigitte Helm, Alfred Abel and Rudolf Klein-Rogge. Erich Pommer produced it in the Babelsberg Studios for Universum Film A.G.. It is regarded as a pioneering work of the science-fiction genre in movies, being among the first feature-length movies of the genre.
1962 – Kathryn S. McKinley, American computer scientist and academic, is born.
Kathryn S. McKinley is an American computer scientist noted for her research on compilers, runtime systems, and computer architecture. She is also known for her leadership in broadening participation in computing. McKinely was co-chair of CRA-W from 2011 to 2014.
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.
