I am a software developer who is enthusiastic about many subjects, including algorithms, computer graphics, analog/digital electronics, science, and engineering.
I use this space to organize my thoughts on various subjects, which may be incomplete or inaccurate, but may still have value for those willing to excercise a bit of skepticism.

The following is an interactive visualization of the first three bands of real spherical harmonics.
