Where's Waldo? How to Mathematically Prove You Found Him Without Revealing Where He Is     Zero-knowledge proofs allow mathematicians to prove claims without explaining why they’re trueLet’s say that you and I are hovered over a chaotic scene in a Where’s Waldo? book, when I triumphantly announce, “I found Waldo!” You, the good skeptic that you are, say, “Oh yeah? Prove it.” Proving it to you would be easy. I could just point him out on the page. But I’m a Where’s Waldo? purist, and I don’t want to spoil your chance to find him for yourself. Is there a way that I could prove to you that I found Waldo without you learning where he is?    Continued here

Using AI to Adjust Your Marketing and Sales in a Volatile World     Why are some firms better and faster than others at adapting their use of customer data to respond to changing or uncertain marketing conditions? A common thread across faster-acting firms is the use of AI models to predict outcomes at various stages of the customer journey. These firms are using AI to predict which customers are likely to churn, while their competitors react after the customers have already left. And when their predictions go off track because of external changes or market conditions, they use that feedback to quickly reorient and redirect their marketing and sales efforts. Using AI models to predict customer response has translated, in effect, to designing and running a large number of digital experiments that helped these firms respond to market changes faster than firms not using those tools. And while AI tools are far from infallible, they could reshape how we make decisions in functions such as marketing and sales and maintain a competitive advantage. Continued here

How to Give (and Receive) Critical Feedback     New leaders often procrastinate difficult discussions at the expense of themselves and their teams. At the root of this feeling is usually a lack of experience and practice — both of which can be gained with intention and time.

A new life for London's lost rivers     Though most visitors to London think only of the River Thames, the city is a myriad of waterways. Old maps show a skein of rivers and brooks that provided "blue corridors" traversing the city for centuries, providing both sources of food and recreation. But as London boomed, these waterways faded from consciousness – encased by walls, turned into polluted backwaters or simply covered over to run unseen beneath busy streets.But these "secret" rivers are imprinted on London's geography. Marylebone started life as St Mary by the bourne (an old name for a watercourse, in this case the Tyburn); while Bayswater, Knightsbridge, Westbourne and Holborn are all named by waterways that ran through them. Deptford was the site of a deep ford over the Ravensbourne, while Wandsworth is named after the River Wandle. East Ham and West Ham get their names from an old word for an area between rivers (hamm) – in their case, the Lea and the Roding. And while Britain's leading newspapers have left Fleet Street, the River Fleet still runs beneath. Continued here

Yes, Airline Flights Are Getting Bumpier: Here's Why     It’s a perfectly sunny day, with a clear blue sky. The pilot just announced that your flight has reached cruising altitude, so the seat belt sign has been turned off. Passengers are moving about the cabin. Suddenly the plane starts shaking. You instinctively grab the arm of your chair. Passengers who have stood up brace themselves. A baby starts crying.A minute later the alarm passes, your body relaxes, and you exhale deeply. Then the plane drops like a rock. Your stomach leaps into your throat. But there’s no storm outside, not even clouds. What’s going on? Continued here

Readers Respond to the March 2023 Issue     In “Born to Count,” Sam Clarke and Jacob Beck present several experiments that they assert demonstrate that humans are born with an innate “number sense.” But not one of them indicates that the concept of, say, “eightness” is innate. What they instead show is that there is an innate inequality sense, an ability to distinguish which of two quantities is larger, provided that the difference between them is large enough.The various experiments Clarke and Beck describe demonstrate that young children have a concept of order. That is, they can put the elements of a set in order by some criterion. For example, a child may be able to put a golf ball, baseball, softball and soccer ball in order by size. The experiments do not show that these children can count. Continued here

Quantum biology: Your nose and house plant are experts at particle physics     Quantum physics governs the world of the very small and that of the very cold. Your dog cannot quantum-tunnel her way through the fence, nor will you see your cat exhibit wave-like properties. But physics is funny, and it is continually surprising us. Quantum physics is starting to show up in unexpected places. Indeed, it is at work in animals, plants, and our own bodies. We once thought that biological systems are too warm, too wet, and too chaotic for quantum physics to play any part in how they work. But it now seems that life is employing feats of quantum physics every day in messy, real-world systems, including quantum tunneling, wave-particle duality, and even entanglement. To see how it all works, we can start by looking right inside our own noses.  Continued here

This Arctic ichthyosaur should not exist     Australian-born Benjamin Kear is a hunter of the High Arctic. With colleague and friend Jørn Hurum, he chose a quarry, and set off across the treeless expanse of Norway’s Spitsbergen, part of the Svalbard archipelago, where wind and snow roar across the landscape, even at the height of summer. There, the steep sides of barren mountains crumble and slump from erosion, exacerbated by the freeze-thaw cycles of melting permafrost. Soft, almost mud-like pieces of shale slide down their flanks, revealing hints of the creature they pursued.“It’s the hardest field work I’ve ever done,” Kear says, safely back in his Uppsala University office. “You’ve got your rifle on your shoulder and there’s polar bears running around. On our last trip we were stuck in the tents for 36 hours in a blizzard.” Continued here
