What is it like to shadow Elon Musk for two years? To sit courtside as he builds a rocket? Or tears apart an engineer? Or couch surfs at the homes of billionaires? And how on earth do you make sense of it all? Walter Isaacson is the biographer of giants: DaVinci, Franklin, Doudna, Jobs...and now Musk, former enfante terrible, rocket launcher, electric car innovator, and Twitter—er, X—disruptor, to put it gently. In this four part series, author Evan Ratliff (Mastermind, Longform Podcast) sits down with Isaacson to draw out the behind-the-scenes stories of this epic biography, and what the writer has learned as an outsider inside Silicon Valley.

When Mangesh Hattikudur (Part-Time Genius, Humans Growing Stuff) set out to do a big, sweeping show on astrology, he didn’t realize the first interview would change the course of his life. But as he tries to put his world back together, he realizes the incredible ways astrology presents itself in modern society: from NASA employees who keep their belief in astrology in the closet, to world leaders who’ve used astrologers to guide foreign policy, to moneyball statisticians who use astrology more than statistics to build baseball teams, to a little shop in India where your fortune was written for you centuries ago, and is waiting for you to come claim it. Over the course of 8 episodes, Mangesh tries to decipher why we keep looking to the stars for answers, and what happens when you don’t believe in astrology, but astrology keeps happening to you.
