I have an amateur interest in combinatorial game theory and rarely update a blog with some basic exposition on the subject (see website).

If you need to contact me, use the e-mail address at this link.

comment LaTeX/TeX Vs. Mathematica for Typesetting
Regarding Scientific Word, it has taken some years, but I would now say that LyX (which is free) is better.

comment Intuition about the Riemann and Ricci tensors
I couldn't quite find an applet that would do what I wanted, although things like torus.math.uiuc.edu/jms/java/dragsphere were close. Basically, I would recommend doing an explicit approximate calculation of the Riemann tensor (and then sectional curvature) for a sphere with the two directions starting out orthogonal. Only from working through the definitions with a toy case like that did I get the sense that "positive Gaussian curvature really should have positive sectional curvature as defined in terms of the Riemann tensor", which really helped me feel better about it.

comment Identification of real functions
Be careful, I think your definition of infective is not what you want. I assume you want $f (\bullet; 0,1)\ne f (\bullet; 0,1) $, but your text says that both coordinates differ.

comment Any interesting properties of Fermat's Last Theorem Surfaces?
Given the mathematics involved in the proof of Fermat's last theorem, I thought from the title that the question might have been about elliptic curves or something.

comment Why do you need to use the chain rule in differentiation of ln?
@Goos Thanks, I'm still not used to just how much MathJaX actually supports in posts.

comment Primes created by “n + digital-root(n)” sequences
@gammatester The pattern is that each starting point for a record number of steps is itself prime.

comment Name/significance of integral of the square of a probability density function
@Did Thank you for your comment. $E(f(X))$ is somewhat satisfying as it is an interpretation that is easy to explain/sounds meaningful in the discrete case, but still applies in the continuous case. Do you want to turn your comment into an answer?
