Math Professor Invents Non-Reversing Mirror

From techfragments:

When you look in a normal mirror, the image you see of yourself is in reverse. But a mirror invented by Drexel University mathematics professor Dr. R. Andrew Hicks shows you your face without reversing its image. Other trick mirrors can show a non-reversed image to a viewer by locating two mirrors at right angles, such that looking at the glass shows basically a reflection of a reflection. The Hicks non-reversing mirror is different- it is one single, smooth curved piece of glass which shows a non-reversed image.

Hicks’s work with remarkable mirrors gained media attention this past summer when one of his inventions, a driver’s side mirror that eliminates the blind spot with minimal distortion, received a U.S. Patent. The curved driver’s side mirror has a field of view of about 45 degrees, compared with 15 to 17 degrees of view in a regular driver’s side mirror. (“Wide angle substantially non-distorting mirror” United States Patent 8180606)

Now his non-reversing mirror is getting another kind of attention. It is now on display as part of an art exhibition in a New York City gallery by artist Robin Cameron, who was inspired by Hicks’s story after she discovered it through online research. Hicks and Drexel University have loaned her the non-reversing mirror for use in her group of artworks entitled “P-R-O-C-E-S-S-E-S.”

“The mirror specifically relates to this particular grouping of work because it is about process. I wanted to know more about what leads someone to make a non-reversing mirror,” Cameron said.

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.

  1. I think they’re overstating the ‘invention’ part of this, isn’t it a well-known optical technique? As soon as I saw the headline and before I saw the article or the photo I thought “it’s just a curved mirror, isn’t it?” And I’m no physicist/optical engineer/thingo.

    You can see the same effect by looking into a spoon.

  2. @perlun: I suggest you read the entire article, which explains where this ‘invention’ part comes in. This isn’t a simple concave mirror.
