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.

"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.

"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

“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).

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.
