Joys of Compounding

Our teacher today is Christian Harrison, the reigning Australian Open and US Open men’s doubles champion.

Christian grew up in a tennis family, learning the game from his father and lifelong coach Pat alongside his older brother Ryan, and by 14 he was one of the top-ranked players in the world for his age. Then a misdiagnosed bone infection started a decade of setbacks that included eight major surgeries. What stands out is that he never lost his joy for the game, and that thread runs through the whole conversation.

Rick and Christian talk about what his parents did to keep him going, why he played his first Grand Slam singles win at Wimbledon on a chipped heel bone, his pivot to doubles and grind back up through the Challenger circuit, the partnerships with Evan King and Neal Skupski that took him to two major titles, and how he handles success after so many years defined by adversity.

Please enjoy class with Christian Harrison.

Our teachers today are Frank Cogliano, Brendan McConville, and Patrick Griffin, three of the world's leading historians of the American Revolution and contributors to The American Revolution at 250, a new collection of essays Frank edited for UVA Press.

Frank, Brendan, and Patrick compare the bicentennial they watched as kids in 1976 with the mood of 2026 and explain why almost nobody saw independence coming in 1774. They make the case that the Revolution succeeded because it paired Enlightenment optimism with a hard-eyed view of human nature, never promising a perfect republic, and they trace how committees built for resistance quietly became a government. They unpack what Dunmore's Proclamation did to the system of slavery, debate whether a country can hold together without its founding myths, and close with Frederick Douglass, a naturalization ceremony at Mount Vernon, and what gives each of them hope for America at 250.

Please enjoy class with Frank, Brendan, and Patrick.

Our teacher today is Nilam Ganenthiran, founder and CEO of Beacon, a centrally managed technology holding company that acquires the vertical software businesses serving the real economy.

Nilam shares the immigrant story that shaped him and why trust becomes the scarce resource as AI turns competence into a commodity. He revisits the hard lessons of his eight years building Instacart, from leading in wartime to the morning Amazon bought Whole Foods. And he lays out the thesis behind Beacon, the bet that distribution and trust hold their value even as the cost of building technology falls, and why he sees a holding company as the right vessel to serve the parts of the economy that technology too often forgets.

Please enjoy class with Nilam Ganenthiran.
