LaTeX in WordPress
I just found out that WordPress.com supports LaTeX math markup! It’s pretty easy to use. (For lack of any ideas original or even remotely profound!)
Not a Julia set!
Following my previous post, I put together a primitive Mandelbrot explorer. Rambling through the Mandelbrot landscape, I found this:
Fractals
I’ve just updated my blog header to use part of an old fractal wallpaper. It’s a part of the Mandelbrot set, located somewhere between the second and third bulbs. I foolishly forgot to make a note of where, because I … Continue reading
Fire simulation with FDS
Last November I downloaded something called Fire Dynamics Simulator, which is made by NIST (the US government’s National Institute of Standards and Technology). If there’s one thing I admire about the United States government, it’s that it actually does useful … Continue reading
GPU temperature control
Open Hardware Monitor has been running (via a scheduled task) on my machine, since I discovered it in February. It collects data on the 36 sensors in my system, and logs it every 5 seconds. I’m generally pretty happy with … Continue reading
Music synthesis
Music, like genetic information, can be expressed at points along a spectrum of detail, from abstract representations to physical phenomena. In each case, moving an element from one representation to another along the spectrum is a process of translation.
Galaxy animation from 2010
I’ve been rewriting a gravity simulator (see my earlier posts on ephemerides and relativity). This isn’t because I’ve thought of a better design or come upon a better technology for it. It’s because I lost the first version! I’ve recovered … Continue reading
Faking relativity
As you know, the orbit of Mercury about the Sun cannot be explained entirely by Newtonian physics. In an ideal Newtonian system, the orbit of a small body around a larger one is a stationary ellipse. In the case of … Continue reading
Ephemerides from JPL Horizons
Ephemeris is a strange word that evokes both scientific and mystical ideas.
