is this how you describe with the use of diagrams how nuclear energy is used to generate electricty?

So my interested was piqued recently by the idea of web crawlers. I've done some research, and read a dissertation published in 2000 by the creator of webcrawler.com, which is now a bit outdated.

I am looking for some modern dissertations or examples of crawlers I should read, preferentially something not too laden with jargon. I'm not a CS major, but a biochemist with some interests outside the field.

Also, I definitely know that Python is an easier language and NOT efficient in comparison...but is it efficient enough to start out with?

I'm contemplating asking my boss (who owns a local restaurant) for access to all his data since he opened, including sales, profits, order information, unique customer counts, etc. I'd like to create a part time position for myself in which I comb over the data and find ways to make the business more efficient.

I've been trying to think of what I could look at, and I came up with a few ideas like testing which menu items sell significantly more/less than others (assuming they should all sell approximately the same), which promotion methods have a significant increase on customer business over their run time, etc. I was even considering comparing what items return customers are more likely to buy (based on stored credit card numbers), and creating a predictive model for how much food to order for certain days (based on combined sales info for past decade).

I was wondering if these ideas seem statistically sound, and if you think I'd be likely to have any sort of success - and what else I could look at, of course. I know I'm missing some important methods.

Make x the subject of the following equation:

y = (x-7)/(x+3)

So now, friends. I'm in need of good science, and space wallpapers. Please help out a fellow anon.
