How does the sunstone work?
If you put a dot on top of the crystal and look at it from below, two dots appear, because the light is "depolarised" and fractured along different axes.
You then rotate the crystal until the two points have exactly the same intensity or darkness.
I like stories about rediscovered ancient technologies but in this case, a youtube video, an image or even an animation of the device would have been helpful.
- kristopolous 13y agoyou can find a number of shaky-cam amateur examples on youtube of them. I'm quite surprised that there isn't some googlable drawing of the thing in a textbook-quality form - you know, like http://outreach.atnf.csiro.au/education/senior/astrophysics/images/spectra/prismdispersion.gif http://outreach.atnf.csiro.au/education/senior/astrophysics/... this - but instead for sunstones.
- johnohara 13y agoThanks kristopolous, I will. Appreciated.

- johnohara 13y agoPleasant surprise. Thank you for showing me how to navigate a professional career path too.
- kapnobatairza 13y agoNot quite sure how I helped you with the latter but I am glad to help!
