3QD Design History and Credits

The original site was designed by S. Abbas Raza in 2004 but soon completely redesigned by Mikko Hyppönen and deployed by Henrik Rydberg. It was later upgraded extensively by Dan Balis in 2006. The next major revision was designed by S. Abbas Raza, building upon the earlier look, and coded by Dumky de Wilde in 2013. And this current version 5.0 has been designed and deployed by Dumky de Wilde in collaboration with S. Abbas Raza.

3 Quarks Daily

3 Quarks Daily started in 2004 with the idea of creating a curated retreat for everything intellectual on the web. No clickbait, no fake news, not just entertainment, but depth and breadth —something increasingly hard to find on the internet today. If you like what we do, please consider making a donation.
