The National Museum of Natural History – Smithsonian Institution
I visited this museum in the 80s and didn’t have time to fully explore it – it’s somewhere I’d like to re-visit someday.
This website doesn’t have a very promising front page and I think if I hadn’t known the place I might have just hit the stumble button without looking further. It is worth exploring though.
I particularly like these SEM images (ant and snail teeth):
I bought my first Gary Larson Far Side book here 🙂
