Back in the 1980s, you could learn how to add memory cards to your PC in a Radio Shack.

In the 1920s and 30s, when Radio Shack was young, a much earlier generation of nerds swarmed into these tiny shops to talk excitedly about building radios and other transmission devices. You might say that Radio Shack helped define gadget culture for four generations, from radio whizzes up to smartphone dorks.

Radio Shack is meeting the fate of many other stores that were wildly popular in the twentieth century, including record stores, comic book stores, bookstores and video stores.

Millions of nerdy kids who grew up in the 1980s could only find the components they needed at local Radio Shacks, and the stores were like a lifeline to a better world where everybody understood computers.

We can celebrate how far we've come from our sexist past when women and men are equally represented in the pages of science fiction anthologies.

Women are being welcomed into science fiction, but it's through the back door.
