Seeing is believing : Illustrations were essential in spreading new scientific and medical ideas and it was often the case that new developments in the sciences were accompanied by corresponding developments in illustrative techniques.

1957 atomic revolution comic book. Quite a find for 1950s atomic memorabilia enthusiasts. Creepy and educational. Has anyone here ever heard of M.Philip Copp?

The Umbrella Sail at Last a Reality! Technofetishists will love this fabulous collection of Popular Mechanics covers going back to 1902. Who'd have thought a weaving machine could be so beautiful? Futuristic cityscapes, bizarre weapons, new-fangled sports and surprisingly delicate and artful scenes are just a few of the pleasures in the year-by-year archive. The mag's male-dominated world can get kind of, um, gay, but it's hard to imagine a better display of the joys and fears (especially the fears) of our monkey fascination with technology.

Buddhist mandalas? Abstract doodles? Alien snow crystals? Nope. Just some amazing scientific art from Art Forms in Nature, published between 1899 and 1904 by zoologist Ernst Haeckel. Lots more early biological art at this scientist's public domain archive. Unfortunately, Haeckel also helped provide the philosophical foundation for Nazism. Hey, no one's perfect.
