Beautiful and informative website from the old age: Tables, tiling background pictures, no fancy fonts or colors, even the formulas (equations) are typesetted as low-res bitmaps instead of contemporary MathML/JS/etc. For me, it feels like leafing throught an old vintage book (I have plenty of old math books left from my studies).

I find it quite funny that clicking "the author" brings us to Linkedin, feels like going back to reality.
