Museum Pix

Cave Bear Fossil

Cave Bear Skull

I’ve uploaded a full set of pictures from our recent visit to Boston science-oriented museums. Gaze here if you’re interested.

I'm interested. I like Aye Aye in particular. And I saw one of the R2D2 mailboxes in NYC this weekend.

According to Wikipedia, he's the world's largest nocturnal primate.

Aye Aye, not artoo.

For me, it's a toss-up between the Aye-aye and the Jimmy Durante nose on the Saiga antelope.

I was confused by the two pictures of "silver." One of them looked like it might not have been silver. Labeling error or is Ag actually available in crystalline form?

PS: the bug pix were awesome. :)

Cool pix, James!

Well I know there are silver salts (AgCl, AgCN, etc.) and you can generally crystalize salts so I'm guessing that that is crystalized silver chloride. Silver (and gold) salts are how they electroplate silverware and jewelry. Dip uncoated metal into Silver Cyanide solution, add electric current and voila (I'm sure I just oversimplified but hey what do you expect I only worked at Reed and Barton for a summer and in the waste treatment facility).

I don't know the composition of the crystals, but it's probably some sort of silver salt, like B.O.B. suggests. I'm neither a geologist nor a chemist, so I rely on them.

The thing appeared to have wires of silver growing out of it, which was really weird.

Cool! I liked the congenital hand deformaties, but the insects were the best!

If you google images of silver you can find:
"Specimens of Native Silver usually consist of wires that are curved and intertwined together, making an inspiring mineralogical curiosity."

That's from here:
http://www.galleries.com/minerals/elements/silver/silver.htm

But there are also "silver bearing minerals," such as polybasite, which looks more like the other picture of silver.

I know very little about minerals, but the mineral room at HMNH is a gymnasium-sized room full of cases of minerals (apparently about 4,000 displayed, according to the website). Choose a mineral, and there are several samples, possibly whole cases of different varieties.

Okay. I didn't even recognize them as wires. I thought they were twigs or roots (like from a tree)!
