In the desert of Peru, hundreds of enormous ancient drawings are carved into the dirt. They’re called the Nazca Lines, and archeologists are still arguing over what they mean.

“The first three of these “division algebras” would soon lay the mathematical foundation for 20th-century physics, with real numbers appearing ubiquitously, complex numbers providing the math of quantum mechanics, and quaternions underlying Albert Einstein’s special theory of relativity.”

Four-Dimensional Numbers: The Quaternions

“But would such numbers ever have practical applications? As it happens, these are exactly the numbers used to describe the orbits of the motion of pairs of pendulums. And quaternions have been recognized in recent years as one of the most effective means of communicating information about rotations to a graphics computer. Thus some of the most abstract algebraic constructions in four-space can be visualized as geometric phenomena.”

President Donald Trump has authorised a 90-day pause on reciprocal tariffs for all countries except for one, China. The president slapped a bespoke 145% tariff on Beijing, effectively ending trade between the world’s two largest economies.

What does this new world order mean for the rest of us? Where will this tit-for-tat trade war end? Will there be any winners? Or could it escalate into something much worse?
On this episode of The Fourcast, Matt Frei is joined by Fiona Hill, who was senior director for European and Russian affairs on the US National Security Council during the first Trump presidency and is now a senior fellow in the Centre on the United States and Europe at the Brookings Institution.
