America’s 250th birthday calls for a history as sprawling and contradictory as the country itself. 

A History of the United States in 100 Objects — hosted by Roman Mars and produced by BBC Studios and 99% Invisible — tells that history one thing at a time. A gold coin from an 1857 shipwreck that triggered a financial panic. An antebellum schoolbook that became an instrument of Black liberation. A ceramic dalmatian from the set of Wheel of Fortune. Or a tiny screw that shows how the US created a hidden industrial empire.

Each week, an object opens the door into an extraordinary, often shocking story — about who we’ve been, what we’ve built, and what we’ve allowed ourselves to forget. Some of these objects are well-known. Many are not. But all of them carry the story of how we got to this moment. This is not one narrative. It’s a hundred of them — forming a kaleidoscope that reveals a country stranger and more fascinating than any single telling could capture.

This is the ninth episode of our ongoing series breaking down the U.S. Constitution.

This month, Roman and Elizabeth discuss Article VI and VII, which include some odds and ends like the Debts Clause, the No Religious Test Clause, and the process for ratification. But tucked into Article VI is the all-important Supremacy Clause, which states that the Constitution is the “supreme Law of the Land,” and is probably the most frequently used constitutional law in practice.

Roman and Elizabeth are also joined by Dr. Alondra Nelson, a leading expert on AI. She discusses why AI is a challenge to regulate, what to think of the tug of war between the states and the federal government on the topic, and whether she’s optimistic governments will figure this out.

One study from 2018 found that Major League Baseball umpires blow about 14 calls every game. That’s 34,000 bad calls every year. And it makes a difference. A blown strike call can decide a win or a loss, a championship or six months at home, wondering what could have been. And while umpires are about 97% accurate in calling balls and strikes, Major League Baseball has been considering something drastic. Something to take us up to 100% accuracy. They have a plan to replace human umpires with robots. Now, with an update!

This is the eighth episode of our ongoing series breaking down the U.S. Constitution.

This month, Roman and Elizabeth discuss Article V, which lays out the process to amend the Constitution.

Then, Jill Lepore lays out her thesis that the Constitution is truly meant to be amended, explains why Article V amendments have become functionally impossible, and tells some fascinating stories about the people who have championed amendments.
