Where can I learn more about synthetic elements?

I'm doing a creative writing project involving the history of synthetic elements. I've exhausted Wikipedia but haven't delved too much into other resources yet. Can someone recommend a website or book or other resource? I don't have a chemistry background, so I prefer information that isn't too technical. Alternately, if anyone here is an expert, feel free to share any info at all--it's all helpful.

Freshly grated parmesan cheese - turns blue in a copper bowl?

My SO and I were having some italian-themed chicken wings, and had some fresh-grated parmesan cheese on the side in a copper bowl. After our meal, we were cleaning up and transferring the leftovers to the fridge for storage, and the cheese on the bottom of the bowl had turned a light blue. Does anyone know why this happened? Given that it happened over only a few hours to just the cheese in contact with the bowl, I'm thinking it was some kind of reaction with the copper.

Silent Science Videos To Entertain Teens?

Looking for videos to create a youtube playlist to entertain a group of science-minded teenagers for about 30 min that are largely visual. Sound is fine but the bulk shouldn't be someone talking to the class like an instructor - visualizations are best - ideally they should look really, really cool. Class is engineering focused, but chemistry, robotics, wobbly bridges, comp-sci, biology, are all welcome. [more inside]

What combination of these materials will create a cool reaction?

Chemistry-buffs, please help! I'm trying to figure out how to create as destructive a chemical reaction as possible (something along the lines of an acid eating through a base) using only limited materials. For story purposes, this reaction has to be created by using some combination of the following materials only: [more inside]

New job selling laboratory equipment, but have no lab/science experience

I recently accepted a sales position within a company that sells laboratory equipment. (i.e. centrifuges, GC's, HPLC's, Thermal Cyclers, etc) I have no previous lab or science experience, so learning about a myriad of highly technical products/methods is a quite challenging. My main challenge comes from the fact that I need to engage in conversations with scientists, chemists, biologists on a daily basis. With no previous lab experience, I've been having a hard time talking to them on technical level. [more inside]

Help me think through Lead in drinking water-- math, chemistry, biology

We're buying a house (still negotiating, hence the anonymity), and we have learned that the level of lead in the water is slightly above the expected range. Not knowing whether this is a big deal, I've tried to do some math to figure out whether being over the threshold is an object of legitimate concern (or whether the range is the fruit of a hyperactive regulatory state) and the process has led me to even more questions.

Smells like SCIENCE

After dropping chemistry post-GCSEs, I find myself reading a couple of books about perfume construction that have made me realise that molecules are interesting, and that if they're written about for a non-scientific audience, I understand and am engaged by them more. How can I learn more without being scared off by Really Hard Science? And are there other books or articles which deal with the construction of scents and smells? [more inside]

Other oils to protect steel

I play an Array Mbira. The tines are made of spring steel. I have sweaty hands, so the tines tend to rust unless I coat them with oil.

Bitter aftertaste in apple butter?

I just made a large batch of apple butter (~8 pecks) in a giant uncoated copper kettle, cooked on top of a wood fire for the better part of the day. The texture is great, but there is a bitter aftertaste (stronger in some parts, like those from the side of the pot, than others) that slightly worries me — what could have caused it, and is it plausibly safe to eat?

How do I stop attracting the wrong guys and start attracting the right ones?

I was just broken up with by a really decent, kind guy because there was no "spark." He seemed like everything I ever wanted in a partner on paper. I knew there was no spark but I was perfectly fine with that, because it seems like the only guys I ever have mutual emotional chemistry with are either rageaholics, substance abusers, or commitmentphobes. I was more than willing to trade the spark for not being yelled at, put down, or inexplicably blown off. [more inside]

Calling all med students, past and present

Thinking back to medical school classes like Biochemistry and Pharmacology, how much foundational knowledge did you actually use from your undergrad courses in related subjects? Was it important to walk in being able to solve all of the kinds of problems you’d see in general chemistry and physics, or were concepts more important? I am trying to understand how much ‘general’ review is required for success before someone who has been admitted actually starts a medical school program.
