Motivating Cohomology Bott and Tu's Differential Forms in Algebraic Topology provides a great introduction to de Rham cohomology, which I've always found intuitive and concrete. |

Is there a general formula for solving 4th degree equations? "However, if you allow special theta values (a new operation, not among the standard ones!) then yes, you can actually write down the solutions of arbitrary polynomials this way." Do you know of a reference which expands on this point? |

Examples of advanced results and ideas explained in a down-to-earth way By accurate I mean more or less that false statements aren't made. Some popular treatments attain their accessible level by communicating half-truths. Again, Feynman's QED is a good example of what I mean: it doesn't cover the details, and it won't teach you how to do the calculations yourself, but it does communicate the ideas of the subject, it does explain some of its more striking applications, and it doesn't make false statements. |

Is value of $\pi = 4$? The downvote came from me. I added it soon after you posted your answer when there weren't any other answers to complement yours. My rationale was that, based on how I've seen other people (not here) attempt to answer this question, anything less than a completely rigorous demonstration would not suffice simply because almost any intuitive explanation seems plausible in this instance. I later tried to remove the downvote when I realized there were a variety of answers and that yours complemented the others nicely, but because an hour had elapsed I was not (and am not) able to do so. |

An Introduction to Tensors I think Qiaochu Yuan's answer is probably closer to what you need for mathematical physics. I still think it's worthwhile reading over at least the first few sections of Keith Conrad's notes. They are actually the nicest source I know of describing general tensor products. |
