I guess that means we have nine senses, since humans can vaguely detect the polarization of light. Check: <http://polarization.com/haidinger/haidinger.html> Jim, the cross-eyed

Just think, one more sense and it will be a whole dime. :-)
And there are many more senses in the animal kingdom: sharks, platypuses, snub-nosed moles, narwhals, bats, all can sense the world through electric fields, echolocation and other methods.. We still don't know how the Monarch butterfly finds its way to its summer home in Mexico.

I do not think that magnetic or electric fields are within human senses; sharks and birds only. Detecting the polarization of light is mostly an understanding that vertically polarized light does not reflect from water, so it probably goes under interpretation, and only once you've worn polarized sun glasses or twisted a polarized lens on a camera. You could divide the tongue into sweet, sour, salty, bitter, hot, and (mostly in the nose) flowery if you wanted to count more than seven physical senses. _______ There are no facts; only interpretation. --Friedrich Nietzsche

I think some people who have an unerring sense of direction have a sense of the earth's magnetic field. Is detecting polarization of light though dependent on vision? Then it's not a separate sense. -- David gnome@hawaii.rr.com authenticity, honesty, community
