Big Data’s Mathematical Mysteries
...than 10 layers in state-of-the-art systems. The Google image-recognition algorithm that won a recent ImageNet Large-Scale Visual Recognition Challenge used 22 layers. Machine learning works spectacularly well, but mathematicians aren’t...

String Theory Meets Loop Quantum Gravity
...the duality. In a recent paper, Verlinde looked at AdS/CFT in a simplified model with only two dimensions of space and one of time, or “2+1” as physicists say. He...
The Quantum Secret to Superconductivity
...have suspected a type of order known as charge density waves — essentially, ripples of overly dense and under-dense regions of electrons. But the new experiment, as well as recent...
Debate Intensifies Over Dark Disk Theory

...field.” In recent years, he said, astronomers have seen hints that large-scale magnetic fields may extend into the voids between galaxies. It’s unknown where a global magnetic field might have...
The Downside to Neanderthal DNA
Interbreeding with Neanderthals was likely a mixed bag for our ancestors. Our recent feature story “How Neanderthal DNA Helps Humanity” detailed how Neanderthals (and Denisovans) supplied early humans with genetic...
Is Infinity Real?
...numbers is notable for its beauty, “a tower of infinities with no connection to physical reality,” as Natalie Wolchover put it in a recent Quanta article on the finite-infinite divide...
New Lizard Shows Evolution’s Predictability
...is related to large lizards from Hispaniola. Scientists still need to figure out why the new anole resembles its Cuban counterpart: Is it because the two share a recent ancestor...
