  • Walter Shawlee, slipstick reseller, has passed.

    Over time, his customers included a weather station in Antarctica, where many electronic gadgets could not take the cold; photo editors responsible for adjusting image sizes (they like slide rules for their clear displays of different values for the same ratio); an archaeologist who found that calculators got too dusty to work properly during digs; the drug company Pfizer, which gave away slide rules as gifts during a trade show; slide rule enthusiasts in Afghanistan and French Polynesia; and “guys from NASA,” Mr. Shawlee told Engineering Times in 2000.

  • Sorry, overwintering turtles don’t breathe through their butts.

    The notion that cloacal gas exchange helps North American turtles survive long winters trapped under the ice is pervasive in pop science, but to date, there is no solid evidence that hidden-necked turtles use cloacal gas exchange. The skin and mouth lining are where gas exchange happens during winter hibernation.

Field trip and workshop resources in the DMV

Here’s a roundup, somewhat Northern Virginia-inflected, of some organizations that run field trips in the mid-Atlantic.

Nature Forward is our standard-bearer. Workshops and camps for kiddos and families, walks focused on birds/geology/botany/etc., CEU-credited courses in lichens/spring wildflowers/conservation history/etc., overseas travel—something for everyone at nearly every level of expertise. NF is also an important advocate for protection of natural areas in the DC metro.

Some outfits mostly interested in birds:

Are you ready for some botany?

Maybe something a little more niche is your interest.

Or you’re looking for something more fast-paced than the naturalist’s shuffle.

The Washington metro is a mosaic of publicly-accessible, natural areas under several different jurisdictions. Check out individual parks and recreational areas for scheduled workshops, camps, and events.

*I know these organizations only by referral/search, not by firsthand field trip experience.
