Amazing Mathematical Mirrors

If you think you've seen it all, mathematician Andrew Hicks at Drexel University, has something really amazing to show you.

Tired of looking at the distorted image oi its bicycle rearview mirror, he figured he could put his knowledge to good use and engineer a better mirror.

The results... are impressive.
You can see some of his mirrors in the image above. The small square one in the middle is a mirror that reflects an "unmirrored" image!
If you raise you right hand, your reflection will raise its right hand as well - must be really awkward to look at! :)

Of a more pratical, he has designed an enhanced vehicle rearview mirror that eliminates the dreade "blind-spot" effect.

From this:

you get to see this:

Besides seeing a lot more, the image remains undistorted (no "curvy" vehicles or bended straight lines.)

I was surprised to find out that curved mirrors aren't allowed in vehicles in the USA. They say that as it alters the sense of distance to the objects, they're not safe to use while driving. Only exception is using it in the passengers side, with the famous warning: "Objects in Mirror Are Closer Than They Appear."

I'm glad Europe prefers a "broader" image in its vehicles.
Hope these mirrors get here soon.
