‘Remarkable’ Mathematical Proof Describes How to Solve Seemingly Impossible Computing Problem

You enter a cave. At the end of a dark corridor, you encounter a pair of sealed chambers. Inside each chamber is an all-knowing wizard. The prophecy says that with these oracles’ help, you can learn the answers to unanswerable problems. But there’s a catch: the oracles don’t always tell the truth. And though they cannot communicate with each other, their seemingly random responses to your questions are actually connected by the very fabric of the universe. To get the answer you seek, you must first devise... the questions. Read More >>

What’s the Most Monogamous Animal?

Animals, we know, typically lack the hang-ups that make human mating so difficult. You won’t find a bonobo moping around, stewing in jealousy. Nor will you find a bonobo contentedly fucking his or her bonobo-spouse to the exclusion of all other viable bonobos for months or decades at a time. And though that particular species may take it to an extreme – mother-on-son action is not uncommon – their non-monogamous nature inheres in most of the rest of the animal kingdom. Only a minority of species operate on the one-partner model, and of these even fewer practice it on something like a human level. For this week’s Giz Asks, we reached out to a number of experts for their take on the latter group’s most monogamous member. Read More >>
