I have a website and a blog.

I have, over the years, contributed a number of images to the Wikipedia.

My preferred gender pronouns are he/him/his.

The Fine-structure constant:

$$\alpha = \frac{e^2}{2 \varepsilon_0 h c} \approx \frac{1}{137}$$

where


 * $e$ is the elementary charge ;
 * $h$ is the Planck constant ;
 * $c$ is the speed of light ;
 * $ε$$0$ is the electric constant.
