Katharine Burr Blodgett #ShapeTheWorld @INWED1919 #INWED20

Today we celebrate Katharine Burr Blodgett,  was an American physicist and chemist known for her invention of “invisible” or nonreflective glass while working at General Electric. She was the first woman to be awarded a Ph.D. in physics from the University of Cambridge.

Here’s more from Edison Tech Center:

Katharine worked with Irving Langmuir who had worked with her father at the GE Research Lab.  They worked on thin films of only a few molecules thick. She developed a way to use single molecule thick coatings of barium to increase the amount of light passing through glass.  She developed non-reflective coatings for eyeglasses and improved lenses used in cinematography. She worked on two patents with Vince Schaefer, another great mind of GE at the time.

She developed a method using a color gauge to measure the thickness of thin monomolecular films in 1933.  Five years later she creates a system to make non-reflecting glass. Normal glass reflects a significant portion of light, however using a coating consisting of 44 layers of liquid soap at one molecule each (four millionths of an inch) she could get 99% of light to pass through the glass.  Later on engineers devised a way to create the same coating which would be durable and not wipe off.


As 2022 starts, let’s take some time to share our goals for CircuitPython in 2022. Just like past years (full summary 2019, 2020, and 2021), we’d like everyone in the CircuitPython community to contribute by posting their thoughts to some public place on the Internet. Here are a few ways to post: a video on YouTub, a post on the CircuitPython forum, a blog post on your site, a series of Tweets, a Gist on GitHub. We want to hear from you. When you post, please add #CircuitPython2022 and email circuitpython2022@adafruit.com to let us know about your post so we can blog it up here.

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.
