We're now entering the winter season of the 80-year four season economic cycle. It's during this season that we'll clear the decks with a devastating crash and debilitating deflation. The economy and markets will shed the excesses created during the preceding fall bubble boom season and prepare the soil for new blossoming in innovation and a spring boom. After the blustering bull market of 2009-2015, we are now preparing for a shakeout more painful than anything we've seen before.

An astonishing technique for recovering and cloning dinosaur DNA has been discovered. Now humankind’s most thrilling fantasies have come true. Creatures extinct for eons roam Jurassic Park with their awesome presence and profound mystery, and all the world can visit them - for a price.

Twitter seems like a perfect start-up success story. In barely six years, a small group of young, ambitious programmers in Silicon Valley built an $11.5 billion business out of the ashes of a failed podcasting company. Today Twitter boasts more than 200 million active users and has affected business, politics, media, and other fields in innumerable ways.

In 2011, a 26-year-old libertarian programmer named Ross Ulbricht launched the ultimate free market: the Silk Road, a clandestine website hosted on the Dark Web where anyone could trade anything - drugs, hacking software, forged passports, counterfeit cash, poisons - free of the government's watchful eye. It wasn't long before the media got wind of the new website where anyone - not just teenagers and weed dealers but terrorists and black hat hackers - could buy and sell contraband detection-free.

Americans as a whole view themselves as reasonably prudent and sober people when it comes to matters of money, reflecting the puritan roots of the earliest European settlers. Yet as a community, we also seem to believe that we are entitled to a lifestyle that is well-beyond our current income, a tendency that goes back to the earliest days of the United States and particularly to get-rich-quick experiences ranging from the Gold Rush of the 1840s to the real estate bubble of the early 21st Century.

In 2006, hedge fund manager John Paulson realized something few others suspected - that the housing market and the value of subprime mortgages were grossly inflated and headed for a major fall. Paulson's background was in mergers and acquisitions, however, and he knew little about real estate or how to wager against housing. He had spent a career as an also-ran on Wall Street. But Paulson was convinced this was his chance to make his mark. He just wasn't sure how to do it. Colleagues at investment banks scoffed at him and investors dismissed him.

When turmoil strikes world monetary and financial markets, leaders invariably call for "a new Bretton Woods" to prevent catastrophic economic disorder and defuse political conflict. The name of the remote New Hampshire town where representatives of 44 nations gathered in July 1944, in the midst of the century's second great war, has become shorthand for enlightened globalization.

Signals is the story of the world economy, told in the language of everyday objects, places and events - from magazine covers and supermarkets to public protests. Pippa Malmgren argues that by being alert to the many signals around us, we can be empowered to deal with the varied troubles and treasures the world economy inevitably brings. Economics is not just maths and data. Perfume and makeup are part of the world economy, too.

In 1971, President Nixon imposed national price controls and took the United States off the gold standard, an extreme measure intended to end an ongoing currency war that had destroyed faith in the U.S. dollar. Today we are engaged in a new currency war, and this time the consequences will be far worse than those that confronted Nixon. Currency wars are one of the most destructive and feared outcomes in international economics.

Wall Street is an unending source of legend - and nightmares. It is a universal symbol of both the highest aspirations of economic prosperity and the basest impulses of greed and deception. Charles R. Geisst's Wall Street is at once a chronicle of the street itself - from the days when the wall was merely a defensive barricade built by Peter Stuyvesant - and an engaging economic history of the United States, a tale of profits and losses, enterprising spirits, and key figures that transformed America into the most powerful economy in the world.
