Inside the List - NYTimes.com Carol J. Loomis's "Tap Dancing to Work," an anthology of Fortune magazine articles by and about the cuddly billionaire Warren Buffett, is new on the hardcover nonfiction list at No. It's hardly the first time Buffett (inset, top) has turned up on this page: "The Warren Buffett Way," an investment primer by Robert G. Hagstrom, spent five months on the list in 1994 and 1995, and two biographies, Roger Lowenstein's "Buffett" (1995) and Alice Schroe­der's "Snowball" (2008), were also best sellers. Warren Buffett, top, and Jimmy Buffett. But Loomis, an editor at large for Fortune, trumps them all by including Tyler Maroney's brilliantly loopy (and mostly sincere) investigation, "Are Jimmy and Warren Buffett Related?" Here's how it starts: "We'll begin to answer the question of blood ties between the Oracle of Omaha and the Minstrel of Margaritaville by pointing out their similarities, which are haunting. Both play stringed instruments: Jimmy a tropical guitar, Warren a mean ukulele. . . . They've both cashed in on unlikely investments: Warren bet on furniture, insurance and vacuum cleaners and is now worth $35 billion; Jimmy bet on the illusion of a colada-drenched beach bum and forged a multimillion-dollar brand with over 30 albums, eight movies, a clothing line, nightclubs, a custom record label, three best-selling novels and hundreds of gift-shop gimmicks. Jimmy's a Capricorn, adept at accumulating money; Warren's a Virgo, with a creative musical mind. Zodiac aside, the premise isn't as far-fetched as it sounds - how many Buffetts can there be? But alas. As Loomis reveals in a coda, DNA testing (yes, seriously) has ruled out the possibility of a blood relationship. DEEP THOUGHTS: After the 2008 crash seemed to vindicate some of the gloomier ideas in Nassim Nicholas Taleb's best seller "The Black Swan," my financial-world friends occasionally cited Taleb as a sort of mystical guru figure. It's an image he cultivates, to judge from the author photos that show him clutching himself soulfully in a dark blazer and Steve Jobs turtleneck. ("I want you to write down that I started wearing them before he did," the famously pugnacious Taleb told one journalist recently. "I want that to be known.") But though Taleb's eclectic new book, "Antifragile," is selling well - it enters the hardcover nonfiction list this week at No. 8 - there are signs the spell is wearing thin. At The Financial Times's Alphaville blog, a former fan complained that the new book reads like an extended version of the mock-­ponderous "Deep Thoughts" that Jack Handey used to write for "Saturday Night Live," and reviews elsewhere have ranged from tepid to scathing. Here's a taste of John Crace's summary from his Digested Read column in The Guardian: Wind extinguishes a candle and energizes fire. How deep is that? The answer, counterintuitively, is not quite as deep as me. For I, Nassim Nicholas Taleb, alone have discovered the secret of the universe. It is the antifragile. What in God's name is that? Wittgenstein asked me over lunch in a three-starred Michelin restaurant in Paris. You know how some things are quite fragile, and we're really scared of them breaking? Well, my brilliant new idea is that sometimes it's good that things get broken, because that's when important changes like evolution can happen. And because I'm the only person who has ever thought this, I'm going to call it antifragile.
