What People Say About 3QD




"I couldn't tear myself away from 3 Quarks Daily, to the point of neglecting my work. Congratulations on this superb site."

—Steven Pinker, Johnstone Professor of Psychology, Harvard University.




"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.




"3 Quarks Daily is smart and highclass."

—Robert Pinsky, only three-term U.S. Poet Laureate.




"3 Quarks is a daily must-read for intellectuals of all stripes. It is perhaps even smarter and better and more comprehensive than Arts & Letters Daily, the de facto gold standard of the smart set on the internet."

—Laura Claridge, former Professor of English at the U.S. Naval Academy, and author of Romantic Potency: The Paradox of Desire, Tamara de Lempicka: A Life of Deco and Decadence, and Norman Rockwell: A Life.

"Thanks for 3 Quarks Daily which has been very high on my reading list for several years now!"

—Huw Price, Bertrand Russell Professor of Philosophy and Fellow of Trinity College at the University of Cambridge. He is also co-founder, with Martin Rees and Jaan Tallinn, of a project to establish a Centre for the Study of Existential Risk.




“I’m a longtime fan of 3 Quarks Daily!”

—Ben Orlin, author of four best-selling mathematics books: Math with Bad Drawings (2018), Change is the Only Constant (2019), Math Games with Bad Drawings (2022), and Math for English Majors (2024).




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

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




"3 Quarks Daily is a warm and often amusing home for intellectuals and other wags."

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.
