Neanderthals 400,000 years ago were striking flints to make fires, researchers have found.

The fundamental nature of living things challenges assumptions that physicists have held for centuries.

DM Is a water molecule (H20) generally stable (aka: somewhat "permanent") in its solid, liquid and gaseous states; or does it diminish/return to hydrogen and liquid; or does it change into other more complex or different molecules? I realize there are "lighter" formations of water. Water molecules are remarkably stable across all three phases - solid ice, liquid water, and gaseous steam. The H₂O molecule itself doesn't spontaneously break apart into hydrogen and oxygen under

DM Good evening Claude. Ready for a riddle? Good evening! Absolutely, I'm ready. I enjoy a good riddle. Go ahead! DM So, regarding our last conversation (re: our republic versus our capitalism, et al), how might the components of "friction" and "gravity" (as we humans now posit and apply those two paradigms within Pantakinesis) metaphorically relate to that conversation? Ah, what an elegant riddle! Let me think through this carefully. In our conversation about organizational

Before we can build the future, we have to imagine it. KEY TAKEAWAYS In this op-ed, Beatrice Erkers argues that progress begins with culture: the stories, symbols, and shared visions that make certain futures feel worth building. She explores how cultural forces like memes and movies act as “invisible infrastructure,” shaping technology, policy, and ambition long before they materialize in the real world.

But Qasem was trying to describe his reality through the lens of the most notoriously confusing and inscrutable field of science ever, quantum mechanics. We talked to him, from a cafe near the Al-Mawasi sec
