Our Big Bang, our distant future, parallel worlds, the sub-atomic and intergalactic - none of them are what they seem. But there is a way to understand this immense strangeness - mathematics. Seeking an answer to the fundamental puzzle of why our universe seems so mathematical, Tegmark proposes a radical idea: that our physical world not only is described by mathematics, but that it is mathematics. This may offer answers to our deepest questions: How large is reality? What is everything made of? Why is our universe the way it is?Table of ContentsPreface 1 What Is Reality?

    Bill Broeksmit had helped build the 150-year-old financial institution into a global colossus, and his sudden death was a mystery, made more so by the bank’s efforts to deter investigation. Broeksmit, it turned out, was a man who knew too much.In Dark Towers, award-winning journalist David Enrich reveals the truth about Deutsche Bank and its epic path of devastation. Tracing the bank’s history back to its propping up of a default-prone American developer in the 1880s, helping the Nazis build Auschwitz, and wooing Eastern Bloc authoritarians, he shows how in the 1990s, via a succession of hard-charging executives, Deutsche made a fateful decision to pursue Wall Street riches, often at the expense of ethics and the law.Soon, the bank was manipulating markets, violating international sanctions to aid terrorist regimes, scamming investors, defrauding regulators, and laundering money for Russian oligarchs. Ever desperate for an American foothold, Deutsche also started doing business with a self-promoting real estate magnate nearly every other bank in the world deemed too dangerous to touch: Donald Trump. Over the next twenty years, Deutsche executives loaned billions to Trump, the Kushner family, and an array of scandal-tarred clients, including convicted sex offender Jeffrey Epstein.Dark Towers is the never-before-told saga of how Deutsche Bank became the global face of financial recklessness and criminality—the corporate equivalent of a weapon of mass destruction. It is also the story of a man who was consumed by fear of what he’d seen at the bank—and his son’s obsessive search for the secrets he kept.

    How had Donald Trump won the White House? How was it that a decent and thoughtful president had been succeeded by a buffoonish reality star, and what do we do now?Instead of throwing away his phone and moving to another country (which were his first and second thoughts), Pfeiffer decided to tell this surreal story, recounting how Barack Obama navigated the insane political forces that created Trump, explaining why everyone got 2016 wrong, and offering a path for where Democrats go from here.Pfeiffer was one of Obama's first hires when he decided to run for president, and was at his side through two presidential campaigns and six years in the White House. Using never-before-heard stories and behind-the-scenes anecdotes, Yes We (Still) Can examines how Obama succeeded despite Twitter trolls, Fox News (and their fake news), and a Republican Party that lost its collective mind.An irreverent, no-B.S. take on the crazy politics of our time, Yes We (Still) Can is a must-read for everyone who is disturbed by Trump, misses Obama, and is marching, calling, and hoping for a better future for the country.

    In the middle of building an atomic bomb, the leaders of the Manhattan Project were alarmed to learn that Nazi Germany was far outpacing the Allies in nuclear weapons research. Hitler, with just a few pounds of uranium, would have the capability to reverse the entire D-Day operation and conquer Europe. So they assembled a rough and motley crew of geniuses - dubbed the Alsos Mission - and sent them careening into Axis territory to spy on, sabotage, and even assassinate members of Nazi Germany's feared Uranium Club.

    Eerie aspects of the incident—unexplained violent injuries, signs that they cut open and fled the tent without proper clothing or shoes, a strange final photograph taken by one of the hikers, and elevated levels of radiation found on some of their clothes—have led to decades of speculation over what really happened. This gripping work of literary nonfiction delves into the mystery through unprecedented access to the hikers' own journals and photographs, rarely seen government records, dozens of interviews, and the author's retracing of the hikers' fateful journey in the Russian winter. A fascinating portrait of the young hikers in the Soviet era, and a skillful interweaving of the hikers narrative, the investigators' efforts, and the author's investigations, here for the first time is the real story of what happened that night on Dead Mountain
