A mysterious new shape seems to say something fundamental about the nature of the universe. Can we understand its message?

Plato set out to explain everything with five perfect shapes. His theory died centuries ago. But in 2013 a shape called the amplituhedron burst upon the science scene. Physicists find it performs a miracle. But they don’t know how. The answer may hold a deep truth physics can sense but can’t quite find. Understanding the […]

Twist and Shout: Topology In Action

As Chubby Checker sang and showed a 1960s generation, “Let’s do the twist.” Twist is not only an important thing. It is the only thing. Look around; all that you can see is made of twist. How so? The explanation starts with atoms and takes us through topology and Solitaire to the final fate of […]

The Massive Question The Higgs Boson Has No Answer

What is mass? An apple has it. Put one on a supermarket scale: Earth’s gravity guarantees you pay in precise proportion. In 1684 Isaac Newton does the math for mass and gravity. In 1915 Albert Einstein cleans it up. But a deep problem remains untouched: Up close and personal, neither Isaac nor Albert nor anyone […]

What’s Wrong with Relativity?

There is no absolute frame of reference. It’s called the Principle of Relativity. Problem is: The principle is wrong. How so? Let’s take a closer look at what it is. Italian physicist Galileo Galilei had an idea. He said an experiment that’s done inside a smoothly moving ship can’t tell you that it’s moving. In […]

What’s In a Metric? More Than You Might Think

For more than a hundred years a metric has been seen as a good thing. Turns out it’s not; indeed it’s definitely bad.  First, what’s a metric? That gets complicated; it’s an assumed property of space. It’s like a ruler science uses to make measurements of many kinds, like lengths of lines (both straight and […]
