Does anyone know anything about this?

I'd love to hear what people who know what they're talking about, physics-wise, have to say about this.

Well, he lost me at Lagrangian, but I did get the feeling that renormalization isn't about cancelling out infinities with simple division. (I know nothing of this higher level math, yet.)
I was impressed, however, that singer Joan Baez is also an expert on Quantum Mechanics.

I was thinking of a matrix like the one above, with rows and columns (x & y vertices) AND some kind of z vertex (depths?) so the matrix formed a cube instead of a square (or a hypercube, etc.). Is this what you mean? (I'm inferring from your post that you're a few textbooks ahead of where I am...
But few means.
I run into the same thing. When I ask a question, often the answer is more descriptive than creative, and I get the impression that many people here do not ask themselves anything really off the wall about their areas of expertise.

I've been learning about 2D matrices in algebra, like the one below, and was wondering if there were matrices in higher maths that used 3 or more dimensions, and if someone would describe or provide an example. Just curious.
\left[\begin{array}{ccc}1&0&0\\0&1&0\\0&0&1\end{array}\right]...
If we could work \phi and \frac{1}{137} in there somehow, we might have the meaning of life. (Wouldn't it be cool if the resulting equation solved to 42?)

When you solve a problem incorrectly, what's the usual culprit? Is it a "stupid mistake" (such as accidentally adding when you should have subtracted, etc.) or is it a misapplication of a skill?
For myself, as I go along in my learning, whenever I get into trouble in an equation, 9 times out...
I'm graphing equations, and I ran into a snag. I assumed that the graph would be the same for both of the following:
y=x^2 and y=-x^2
since any negative number squared is equal to it's absolute value squared.
However, the book showed equation 2 as having an inverted graph of equation...
