Fantastic resources.

All very cool.

Thank you.

Arrange the lighting near your monitor so that the light source is coming from approximately the same direction as the sun in the image. That may help.

I'm disappointed that they don't have Google Street View for the moon. I guess it is because there are no wireless signals to poach...

OMG I am totally signing up for Old Weather.

Pick a large reference crater. One that's so big that you can't mistake it for anything else, like the one in the upper right of that image. Take note of on which side of the circle the crescent of its shadow falls.

Any concave depression will have the shadow on the same side. Convex bumps will have the shadow on the opposite side.

Also, most craters will have a very slight halo of lighter material around them from where the light falls evenly on the lip of the crater.

Linked in between boxes here, by the bye. Spiffy stuff, Dr. Science!

Incidentally, a while ago I wrote a a comment on one of your first posts, if not your first, post, which resulted in me only belatedly realizing, days later, that it could have been perfectly reasonably interpreted as my implying I thought it was a bad idea for you to post on sf topics; on the chance that you read my sloppy and hasty comment that way, let me assure you that that wasn't in any way what I meant!

I was just, at the time, startled to learn how much of an sf fan you are, and that you had such a fannish history!

So, anyway, I Just Wish To Say clearly that if you do feel like covering any sf topics, I, for one, would be highly interested.

This applies to everything else you think might be interesting, as well. :-)

No worries, Gary! I have something in the works, in fact, which I hope to finish up in between pollworking tomorrow.

I hope one of my fellow bloggers here can get into my posts tomorrow morning and scrape out the spam, because I'll be basically out of the loop -- my shift is from 5:15 am to about 8:30pm.

Only Eric or Slart have the SuperUser password to do that. Or maybe Sebastian does, as well.

I'd be happy to help stamp out spam anywhere and everywhere I could. Of course, since Eric's normal password allows me access to his posts at Newshoggers and Democracy Arsenal, I could always go clean out spam there, if I have spare spam-cleaning time.


As it is, I've been doing plenty of late night and early morning clean up on old threads of Eric's and mine, but that's all I have access to.

Meanwhile, as I wrote a bit ago in Russell's last open thread, I'm not going to have time to post in the next month, save by chance, or in very short and fleeting fashion, at best, so, sorry about that.

So, I can't help but be curious, did you give up on Smallville eventually, or still watch?

I'm still faithfully watching, but can think of many reasons you might have quit caring.

There are humanities projects like this too. The National Library of Australia has a newspaper digitisation project where anyone can help correct the OCR of all the newspapers that have been done. This makes Australia's historic newspapers searchable -- a huge resource for historians that I use all the time in my work. Plus you get to read cool old newspapers.

I find that, in fact, turning my head _does_ help, at least in this instance. Try turning it both ways, until the image seems to invert in your perception. Then try coming slowly back to level, staring at the photo all the while. As a last resort, copy the photo to a program in which you can rotate it 180°.

It's fascinating how stable the illusion is. If I initially see the craters as bumps then no amount of trying dissipates that perception.
