An Online Circus of Bizarre and Outdated Science

Check out this incredible blog hosted by JF Ptak Science Books LLC. John Ptak (the owner of the store and blog author), describes his blog as:

a history of science blog that related to my bookstore, but within the first two months the content spilled over into all sorts of unexpected areas, and I’ve happily not tried to steer a clear course since then.  The categories bar makes sense of the mass of the posts, I think.  At this point there are some 1340 posts that number about 950,000 words and 5,000 images.  This blog has been referenced or has been re-posted in The New York Times, The Economist, The Wall Street Journal, Boing-Boing, Jezebel, Wired,, the Huffington Post and many other places.

Or this perspective piece by renown physicist, Ernst Mach:


Or this vine stem cross-section sketch by plant physiologist, Stephen Hales:


I’m going to leave you with this Thomas Nast cartoon, featured in the 1871 edition of Harper’s Weekly.
