Galaxy Girls

I knew about some of these but most were new storeies to me. For example, I knew how the Apollo Guidance Computer worked and that it used core memory ropes as read-only memory.
But this book talks about the women that made those ropes. Some thing for the women that hat made the space suits. Ihad learned some about the construction of the suits, but not the people behind it.
I recommend it and this would be good bed time stories for kids.
