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]
What readily available materials change state at a constant, predictable rate in an easily observable manner? [more inside]
If you were to combine 1 cup of skim milk and 1 cup of 2% milk, does that essentially give you two cups of 1% milk? [more inside]
What's the best software for prepping for college-level hard sciences? [more inside]
Why does stainless steel have such strange properties? [more inside]
What are the best academic journals in each field? [more inside]
What is the best way to move hot air? Would it be blowing air across the heat source (ex: wood stove) or suck the air away from the heat source? [more inside]
What is the most important scientific question of our time? [more inside]
I don't understand physics. How do atomic orbitals work? [more inside]
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?
why does pernod turn milky when water is added? [more inside]
How has our understanding of Astronomy, Biology, Chemistry, etc. changed in the last five years? [more inside]
Is there a chemical explanation for the density of an element or is it simply an innate physical characteristic? [more inside]
Why do neutrons have more mass than protons? [more inside]
FirstTimeTutorFilter: I'm plan to start tutoring Math, Chemistry, Physics and possibly ESL in January. Only problem is, I have *no idea what I'm doing*. Anyone have any textbooks, general teaching books, online certification courses, etc to recommend? [more inside]
"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? [more inside]
Does household natural gas pool in low places or rise to high places? [more inside]
How could a Coke can leak its contents without any apparent holes? [more inside]
What would happen if you take a cube of ice, at a specific size, and fit it in an airthight glass box with the exact same dimensions, and then let it melt? [more inside]
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?
