Boston University science professor T. Ross Kelly has amassed an impressive collection of strange and wonderful scientific instruments and gadgets, from radiometers to thermobiles to MOVA Globes that he and two students have kindly documented online in "A Scientist's Curiosity Cabinet."
Professor Kelly writes:
Over the past 25 years I have accumulated a collection of various gizmos, devices, toys etc. which to me are excellent examples of scientific principles or things that you look at and you say "That's impossible!" except it's staring you in the face…
In the olden days some people assembled what were known as curiosity cabinets. It is our hope that what we have created will be the modern day equivalent of a scientist's curiosity cabinet.
