The phrase "it's so easy my grandmother could understand it" might sound okay. It's a common expression, right?
But think about it: does that phrase mean that all grandmothers are technologically inept? Or that older women can't understand or contribute to conversations about technology, math, engineering or science?
There are a huge number of grandmas out there who have made great contributions in STEM (science, technology, engineering and mathematics) disciplines. Grandma Got STEM gathers some of their stories, and it's great reading.
The blog was started by Rachel Levy, an associate professor of mathematics at Harvey Mudd College in Claremont, California. She got the idea after overhearing someone say "just explain it to me like you would to your grandmother."
Stories on the blog include first-hand accounts of studying chemistry in Germany after World War II, facing discrimination against women in the laboratory in 1957 (and overcoming it to enjoy a long career at a pharmaceutical company), and starting out as an arts major in the early '60s, only to end up at the forefront of computer and software technology.
There are also some great pieces from family members writing about the huge influence of STEM grannies in their lives, and some stories of historical women who pushed the STEM disciplines forward.
If you've got a few minutes, the blog is really worth a look. And if you have a STEM grandmother whose story you'd like to share (or if you're a STEM grandmother yourself), you can write to Levy on the Submissions page.
