Vikings use Sunstone for Navigation by Polarized Skylight

Many historians, archeologists and physicists still continue to question how Vikings navigated from Norway to America. Recent developments shed light towards Vikings using Polarimetric methods for their navigation. Using a common iceland spar as a depolarizer could have given Vikings an approximate location of the sun.

I have always found Vikings to be a very interesting topic. I think it is fascinating that if recent developments are true, Vikings were able to use such advanced methods of navigation. This just goes to show how early on the study of astronomy began to be explored.

This strongly confirms how Vikings navigated with such an advanced guidance system. This is how they were dominating seas between Norway to America.

That is pretty cool, since it shows that the Vikings were more advanced than historians initially assumed. We all generally assumed (before this article) that the Vikings had used the 'popular' method of star navigation but this is pretty impressive. Kind of like a significant advance in astronomy in the very beginning.
