Anything but clear. It is well known that panes of stained glass in old European churches are thicker at the bottom because glass is a slow-moving liquid that flows downward over centuries. Well known, yes, but long known to be wrong. Scientists still disagree about the nature of glass, and researchers continue to try to understand its dual personality . [more inside]

Dr. James B. Calvert, professor emeritus of engineering at the University of Denver, has an incredibly rich and deep personal webpage, which includes such gems as Latin for mountain men, the correct corn-hog ratio, travel by brachistochrone, anomalous sound propagation and the guns of Barisal, and about a billion other awesomely nerdy topics.

The Works of natural philosopher Robert Boyle (1627 - 1697) at the Robert Boyle Project, based at Birkbeck College, University of London.
Widely regarded as the first modern chemist (his book The Sceptical Chymist is perhaps the founding text of chemistry as a science), he was also an alchemist and made significant contributions in physics (for example Boyle's law) and physiology.
The Robert Boyle homepage has as its centrepiece a large collection of images of Boyles' papers. Images and transcriptions of his marvellous work diaries are available at the AHRC Centre for Editing Lives and Letters.

Not to be confused with its more-disgusting knockoff, mayonnaise has a lot going for it. A favorite Spelling Bee word, a racial litmus test, a hair conditioner--is there anything mayonnaise can't do? Mefi says you can even win prizes with it! What other condiments have spawned theories? Sunday school kids learn about faith and mustard seeds, but is there anything out there for ketchup?
