What People Say About 3QD

"I've recommended your site to a number of friends and colleagues who've bemoaned the dearth of sites with any literary/scientific muscularity. Keep up the wonderful work."

—John Allen Paulos, Professor of Mathematics at Temple University, and bestselling author of Innumeracy

"Mighty interesting website! I've added it to my favorites."

—Daniel Dennett, University Professor of Philosophy at Tufts University.

"I look for relevant research, interesting themes and funny stories on sites like 3 Quarks Daily, Crooked Timber, Boing Boing and Slashdot."

—Clay Shirky, prominent thinker on the Internet and its social and economic consequences, and author of Here Comes Everybody, in The Atlantic.

"3 Quarks Daily is a great website which should be supported!"

—Ned Block, Silver Professor of Philosophy, Psychology and Neural Science at NYU; former chair of the philosophy program at MIT.

"The algorithms that curate your social-media timeline do so with indifference and programmed greed. The humans who curate 3QD do so with love and well-aged wisdom. Read 3QD instead! It’s so much better!"

—Justin E. H. Smith, Professor of History and Philosophy of Science, University of Paris.

"I really appreciate your selection of generally sane and mostly stimulating articles. 3 Quarks Daily has been my goto website at the end of the day, and now also during the day!"

—Horst Ludwig Störmer, Nobel laureate in physics and emeritus professor at Columbia University.

"3 Quarks Daily is one of the most interesting aggregator blogs out there. It puts together stuff from art, science, philosophy, politics, literature. It’s a completely international, cosmopolitan place to get information. It’s become my entry point to reading on the Web."

—Mohsin Hamid, author of Moth Smoke, The Reluctant Fundamentalist, and How to Get Filthy Rich in Rising Asia, in the New York Times.

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.
