I'm trying to brush up on my geology, a science that pretty much passed me by, which is frustrating when people I work with casually start talking about Cambrian this, and Triassic that. Where can I find a large poster / chart detailing all the geological epochs and periods? The chart produced by the Geological Society of America is a good start, but it would be more useful if it was, say, annotated with important events ("Angiosperms evolved here! Gondwana separated here!"), and it it had maps of the positions of continents on it at various times. Has anyone seen anything like this? My searches for geology posters have mostly turned up pictures of mountains, or "Geology Rocks!" logos...
I'm an environmental scientist. I just received an email from a group called "Intech Open Access Publisher", referencing one of my papers, and asking me if I'd like to submit a chapter for a book. My first thoughts were "Oh man, I didn't think that paper was that great...". My second thoughts were "Hmm...I bet this is a form email sent out to thousands of researchers based on a keyword search, and it may well be a waste of time to submit an abstract." Has anyone else had experience in this sort of thing? Is it legit?

Do the curved triangular shapes made when cars (or even pedestrians) take "shortcuts" at T-junctions (seen here near my house and here in Western Sahara, although this seems like a deliberate one) have a name? What's the mathematics behind them? The psychology?
