This image, which I made a few years ago, is based on a tiling of the hyperbolic plane with triangles whose angles are π/2, π/3, π/7. Other than the 7, which can be changed to any higher integer, I couldn’t … Continue reading →

I’ve long had an idea to design “outline” typefaces which, at appropriate low resolution, would mimic certain bitmap fonts that have sentimental resonance. The orange discs are the original dots, of course. The blue arcs are least-squares fits (linear, quadratic) … Continue reading →

to save some integrating

Posted on Saturday, 2010 September 04 by Anton

For my own future reference, in case I lose the bit of paper on which I jotted it. In a function of period 2π, a unit step discontinuity in the nth derivative at phase α contributes this to the Fourier … Continue reading →
