Calling all chem- physics- and math-philes!

For the grad-level education I want, I need an understanding of chemistry, physics, and calculus at a minimum. I have a BA in a tangentially related field (or will in a couple months). What are the best resources for learning these subjects without spending even more time/money on tuition? [more inside]

You've got something on your head there

I've just poured myself a Dark Horse Brewery Tres Blueberry Stout. A slow, steady pour that left a modest head on top. And then a droplet or two skidded around over the foam like a water droplet on a hot frypan for maybe five seconds before disappearing. Darndest thing I've ever seen. Beer geniuses, how did this happen? How can I make it happen again?

A Problem of Scale: Halfway in size between an atom and the universe

"A human is halfway in size between an atom and the known universe"... This is a paraphrased quote I have come across several times. I like it. Who said it first? How true is it in the most literal sense? And, finally, what errors arrive in postulating a universe, or an atom, which can be measured AT ALL from our singular, relativistic, perspective?

Why do porous objects appear darker when wet?

Why do porous objects (wood, textile, hair, etc) appear darker when wet then when dry? A googling gave me this ("surface reflection and refraction"), but that doesn't sound entirely reasonable, as it merely talks of light being scattered, but the light in question is already diffuse. This also gives some suggestions, but nothing conclusive. Any chem/physics MeFiers know this?
