The Guardian put out a photo gallery of the hardest of hard core scientists. You know, the ones who experiment on themselves and put themselves in harm’s way for the sake of science.
Sadly, this list is incomplete.
For no list of tough scientists can be complete without the man they call... Doctor Popsicle.
Hat tip to Ewan for the Guardian list.
Additional: I didn’t realize that the photo gallery was separate from another article asking to compile a list of the “hardest” 100 scientists. You can see discussions on Twitter (and yes, I nominated Dr. Geisbrech, a.k.a. Dr. Popsicle, to be on the list!)
