RE: Magnetic monopoles in spin ice
You say "This is associated with a divergence of the magnetic field". You measure \grad \cdot B \ne 0, when a spin flip occurs?

RE: mathematics markup in steemit?
Conceptually, the platform is good for this, but without some latex support in the markdown, I'm not going to try using it. I feel forced to stick to existing non-steemit platforms for anything mathematical.

fyi. Your brackets would look better if you put left/right markers on them in the latex: {\left( \frac{x}{y} \right)}^2

RE: At Higher Levels It's Hard To Make Math Fun
Math can definitely be taught in ways that take the fun out of it. However, I would guess that being coerced into studying something that you have no intrinsic interest in is the most common way to kill

RE: Professor Claims Math, Algebra And Geometry Promote 'White Privilege'The DNC Dolts are truly lost.
This prof is out of touch with reality in so many ways. As well as showing no evidence of familiarity with any mathematics, also clearly doesn't attend university math classes. Twenty+ years ago when I

A great introductory book is Geometric Algebra for Computer Science: This book includes a lot of the geometry side of Geometric Algebra. For a more axiomatic treatment, see Doran & Lasenby's

RE: Linear Approximations Part 3 - why sin(x) ≅ x near 0
A nice treatment of limits like sin(x), x-> 0 can be found here: In particular, he illustrates sin(x) vs. the chord for small angles, which makes it obvious geometrically that the limit is the angle

Mathjax ( ) encodes the equations without images, so you can rescale your browser page and the equations will always be readable. As a specific example, take a look at a page that uses mathjax, such as:

RE: Continuous Functions
Why do you call e^{2 \pi x} a unit circle? That would make sense if x was purely imaginary, but not on the [0,1) interval. Also, can you point me to a link that shows how math markup done in steemit?
