I am getting really frustrated with my flaky chemistry professor. I don't want to complain about her mistakes to the Dean because I think she's a nice person and has some life circumstances I wouldn't wish on anyone (illness of her own and single caregiver for extremely ill and challenged child). How do I get over my frustration with her, stop resenting her, and also stop feeling upset and anxious when I study? [more inside]

Help me understand hair care chemistry. When I look at the list of ingredients on bottles of conditioner, what ingredients should I avoid. I can't stand the 'waxy' feeling I get from some conditioners. My old favorite standby conditioner changed formulas recently and it now has the dreaded waxy ickiness. NOT looking for specific product recommendations, only for ingredients to avoid or possibly ingredients to look for. [more inside]

Quick chemistry question - do i need to dilute this or is it already diluted [more inside]
I can't get the phrase "Nonoxyl-1,5-Triethylamine" out of my head. Obviously, it is an IUPAC name for an organic chemical, but AP Chemistry was a long time ago and I can't quite map out if it's valid— my hunch is "no." Is there a notable chemical that has a similar name that I might be half-remembering? More importantly, is there a website where I can look things like this up in the future?

I'm giving a presentation next month need a funny joke about the difference between chemists/scientists and engineers (because I'm an engineer doing chemistry) [more inside]
"Silicon based life" is a perennial sci-fi trope - I guess because silicon and carbon share similar-ish valency properties. Has anyone actually tried to flesh out what a silicon chemistry complex enough to support protein analogues would look like? Or more broadly, has anyone proposed schemata for complex, self-replicating chemistries that differ substantially from those we know?
Looking for a chart or table that broadly summarizes/compares the relative bond energies of the most common intramolecular bonds found in organic molecules (think single and double bonds among C, H, O, N, and maybe S too). [more inside]

There's a hair product my friends and I love that's been discontinued. Do you know of any companies or chemists that can duplicate it using the ingredients list on the back of the container for a reasonable price? Is there a minimum volume? Can I sell the extra on Ebay? Is this possible or just a pipe dream?

I am planning to go get my PhD in chemistry and I am waiting to hear back from schools. I have already been accepted to 3 schools (one in the top 10), however, I really like some of the faculty at one located in the 30s in the rankings. How important are the rankings and will they have a big affect on my career?
