Google has put every issue of Popular Science of the last century on line. I have started reading issues in the 20’s and it is amazing how many things there are still around. From the mundane like a maids cart that looks remarkably like what they still use today, to a huge tank to test hull designs that looks like something out of NASA to a street cleaning machine that has all the basics.
Sometimes we forget how smart our predecessors were. Any dopers have favorites from the series? I plan on reading most of the issues.
