I think I discovered that many years ago and forgot. I’ll have to get my polarizing plates out and use them on everything while I take a walk. I have two, so I can rotate them relative to each other.

BTW, Phil, you can turn the sunglasses the other way, so that the arms point away from the camera. That’ll make it easier to get them close up.

[...] heijastunut tai sironnut pilvestä muodostaa erilaisen polarisaatiokuvion taivaalle. Samaan tapaan katsottaessa sateenkaarta polaroivilla aurinkolaseilla, voidaan selvittää minkä suuntainen polarisaatio kaaren kussakin pisteessä on. Tutkijat [...]

Plate O’Shrimp! I just discovered this phenomenon for myself last weekend, looking at a full rainbow through polarized sunglasses. Thanks for the writeup!

Cool. One of those smack yourself on the head things – should have known that. What I really like about it is that it is one of those extremely simple but powerful demonstrations of a physical principle that any kid can do. These are the kind of things that get kids hooked on science and we really need more kids interested in science.

Thanks Ed, I was about to say that. Phil is wrong.

also:
long -> wide (Length is time.)
wide -> broad
travelling -> faring (One travels by foot, stick, or oar.)

The “after the fold” section addressed what I immediately thought of upon reading the first section… Which was this: What about a “circular rainbow” like you see from an airplane if you’re looking out opposite to the sun at a bank of clouds (with the shadow of the airplane in the center)…! Presumably, with polarized glasses, you would see a rotationally matched portion of the circle, but not all of it… Now how about a video of that, Phil!
Ooh, added NB: Airplane may not be needed, if you have a ladder, sprinkler, a low sun on a clear day, polarized lens(es), and perhaps a waterproof camera case … See the bottom of this page for some ideas… Anyone??

And that’s why I can’t use my iMac with my sunglasses on!

Nice pictures of dogs, except that somebody kept putting their sunglasses in the way.

@ Das Boes (#33): I’ve seen that same video used to “prove” that Chemtrails are real not the wacko conspiracy theory that they really are.
