Amplitudhedrons.........................

"Artist’s rendering of the amplituhedron, a newly discovered mathematical
object resembling a multifaceted jewel in higher dimensions. Encoded in
its volume are the most basic features of reality that can be calculated -
the probabilities of outcomes of particle interactions."

"Physicists have discovered a jewel-like geometric object that dramatically simplifies calculations of particle interactions and challenges the notion that space and time are fundamental components of reality."

While reading this essay, three thoughts occurred.  The first was, "I'm glad this makes sense to somebody."  The second was, "if Richard Feynman was a pioneer of this stuff, it must be important."  The third was, "large vocabularies are fairly necessary to physicists too."  

As one who gets an unsettled feeling whenever hearing about "settled science," I loved this conclusion:
“The field is still developing very fast, and it is difficult to guess what will happen or what the lessons will turn out to be.”
