I'm an unabashed Flickr addict. I'd take it over myfriendsterfacebook any day. It's the ultimate way to feel connected to what my friends and family are up to, it's great for sharing work with my design students as well as for them to share their own work with me, and it allows me to transport myself to places I've been and love with the click of a button (ie: search> Lake District, England—voila—utter peace and relaxation ensue).
Flickr is where I keep myself connected, albeit loosely, to the Smithsonian Institution, where I did a summer internship back in the day. The Smithsonian is relatively new to Flickr, with only 15 sets of photos—but each one is a treasure trove of American history/science/culture. They cover everything from astronomy to industrial design to American history. And what should show up on their page the other day? A fantastic set of photographs called Women in Science. Here's how the Smithsonian describes it:
In honor of International Women's Day 2009 and Women's History Month, the Smithsonian Institution Archives (SIA) is pleased to present a sampling of images documenting women scientists and engineers from around the world, most of whom were pioneers in their respective fields, or were the first women to receive advanced graduate degrees in their discipline.
It's a great way to get your feet wet in these often forgotten histories. While some are well known figures (Rachel Carson, Betty Naomi Friedan), I can honestly say that most of the women were new to me. Have a look for yourself...I guarantee you'll get sucked in.
