I was seeing the edge of the eclipse on the ground. I didn't really understand why that worked."</i><br /><br />Actually, you were seeing a sharp image of the edge of the tree canopy projected onto the ground. Normally you don't see that because the sun is an extended source (it's 1/2 degree wide on the sky). An extended source can not cast a sharp shadow and so intuitively you expect to see a blurry shadow. But during a partial eclipse the sun gets "small". In the limit, (e.g. a 99% partial eclipse) the sun becomes a point source and it casts a sharp shadow of the canopy. <br /><br />If you ever get another chance, go looking for the images of the eclipsed sun on the ground. It's <i>way</i> cool. You'll get that chance Aug 21, 2017.Original Mikehttps://www.blogger.com/profile/01714345479248980398noreply@blogger.comtag:blogger.com,1999:blog-6329595.post-46557946793577050132016-08-14T08:50:47.125-05:002016-08-14T08:50:47.125-05:00For the fencing, the lighting and the visuals over...For the fencing, the lighting and the visuals overall have been excellent. Two Brits have been doing really good commentary for the medal bouts. As a fan of a less popular sport I've been delighted with the high quality of the coverage.

What struck me was how noisy the background was behind the divers. The divers pose perfectly still at the edge of the board and behind them is crowd, equipment, banners, etc.<br /><br />On the other hand, watching the water spray off the divers' pony tails in slo-mo was pretty cool.Henryhttps://www.blogger.com/profile/14520113896946845614noreply@blogger.comtag:blogger.com,1999:blog-6329595.post-48273981049929400722016-08-14T08:26:10.296-05:002016-08-14T08:26:10.296-05:00"During a partial solar eclipse the gaps betw..."During a partial solar eclipse the gaps between the overlapped leaves of a tree can turn into pinhole cameras.

The thing to watch is not the sun but the shadows sharpening as the bright part of the sun gets smaller.<br /><br />Leaf shadows become noticeable.rhhardinhttps://www.blogger.com/profile/06901742898653890646noreply@blogger.com
