"The most stimulating English-language reading to be had from anywhere in the world.
— The Canberra Times

"A profound question a treasure trove of ideas...each one is a beautiful and instructive reflection, which encourages thinking and reading."
—de Volkskrant (Netherlands)

"Probably the most useful space at the moment for anyone who wants to peer into the flowering of the most advanced human thought...A surprising territory where one finds, in rigorous disarray, the vanguard of scientific knowledge, at this technological and humanistic moment... Go and read it daily, to have intellectual food for a few months because each of these reflections is a micro-essay on a specific topic that opens doors to reflection and study in all fields of human knowledge."
Vozpopuli (Italy)


"The World's Smartest Website; a salon for the world’s finest minds."
The Guardian




We worry because we are built to anticipate the future. Nothing can stop us from worrying, but science can teach us how to worry better, and when to stop worrying.


Tell us something that worries you (for scientific reasons), but doesn't seem to be on the popular radar yet—and why it should be. Or tell us something that you have stopped worrying about, even if others do, and why it should be taken off the radar.
