Neuroscience Weighs in on Physics’ Biggest Questions
A theory of consciousness can help build a theory of everything.
Build Your Own Artificial Neural Network. It’s Easy!
The first artificial neural networks weren’t abstractions inside a computer, but actual physical systems made of whirring motors and big bundles of wire. Here I’ll describe how you can build one for yourself using SnapCircuits, a kid’s electronics kit. I’ll also muse about how to build a network that works optically using a webcam. And […]
The Forest Spirits of Today Are Computers
We’ve made an artificially panpsychic world, where technology and nature are one.
What Happens to Google Maps When Tectonic Plates Move?
Earth’s tremors can tweak your GPS coordinates.
A Hologram Shows How Space Could Pop Into Existence
The holographic principle—with a real hologram.
Yes, Determinists, There Is Free Will
You make choices even if your atoms don’t.
How the Universe Remembers Information
A “memory matrix” might solve Stephen Hawking’s black-hole paradox.
How Japanese Floating Illusions Reverse-Engineer What We See
The Arais do not merely dissect illusions, but can generate them, taking an image that looks boringly normal and making subtle changes, to color and contrast, to fool our brains. If you don’t know how something works, break it. Science is built on creative destruction: Much of what neuroscientists know of the brain, they know […]
A Theory of Consciousness Can Help Build a Theory of Everything
Neuroscience is weighing in on physics’ biggest questions.
The Noise at the Bottom of the Universe
The origin of quantum noise is the modern incarnation of a millennia-old debate.
