A Solution to a Famous Feynman Problem, ‘Psychedelic’ Breathwork, and an Odd Stone Sphere is Unearthed

This week in science and technology news we’re covering at The Debrief: For decades, physicists have argued about Richard Feynman’s Sprinkler Problem, involving the question of how a reverse sprinkler would operate. Now we may finally know the answer… elsewhere, new studies reveal how breathwork may trigger psychedelic-like states, emotional breakthroughs, and psychological insights without drugs. Meanwhile, a stone sphere unearthed at an archaeological site in Azerbaijan is reportedly unlike anything previously documented in the South Caucasus.

Also, in an exclusive feature, University of Toronto bioethicist KM Bowman, Ph.D., writes for The Debrief about his firsthand experience with uncontacted indigenous tribes: “Through the haze stood a man.
