Inventions History

The wheel was invented some 5,000 years ago, and the modern suitcase in the mid-nineteenth century, but it wasn’t until the 1970s that someone successfully married the two. What was the hold up? For writer and journalist Katrine Marçal, the answer is both shocking and simple: because "real men" carried their bags, no matter how heavy. There were rolling suitcases before the '70s, but they were marketed as a niche product for (the presumably few) women travelling alone, and the wheeled suitcase wasn't "invented" until it was no longer threatening to masculinity.

In Masters of Death, Richard Rhodes gives full weight, for the first time, to the Einsatzgruppen's role in the Holocaust. These "special task forces", organized by Heinrich Himmler to follow the German army as it advanced into Eastern Poland and Russia, were the agents of the first phase of the Final Solution. They murdered more than one and a half million men, women, and children between 1941 and 1943, often by shooting them into killing pits, as at Babi Yar.

Weaving together over 100 years of history with scenes from the contemporary landscape, Labor of Love offers a fresh feminist perspective on how we came to date the ways we do. This isn't a guide to "getting the guy". There are no ridiculous "rules" to follow. Instead Weigel helps us understand how looking for love shapes who we are and hopefully leads us closer to the happy ending that dating promises.

Mankind has a distinct advantage over other terrestrial species: we talk to one another. But how did we acquire the most advanced form of communication on Earth? Daniel L. Everett, a "bombshell" linguist and "instant folk hero" (Tom Wolfe, Harper's), provides in this sweeping history a comprehensive examination of the evolutionary story of language, from the earliest speaking attempts by hominids to the more than 7,000 languages that exist today.

Western exceptionalism - the idea that European civilizations are freer, wealthier, and less violent - is a widespread and powerful political idea. It has been a source of peace and prosperity in some societies, and of ethnic cleansing and havoc in others. Yet in The Invention of Power, Bruce Bueno de Mesquita draws on his expertise in political maneuvering, deal-making, and game theory to present a revolutionary new theory of Western exceptionalism: that a single, rarely discussed event in the 12th century changed the course of European and world history.

When did we begin to be as self-centered as we are today? At what point did we expect to have the right to determine our own lives? When did we first ask the question, how can I be free? It all began in the 1790s in a quiet university town in Germany when a group of playwrights, poets, and writers put the self at center stage in their thinking, writing, and their lives.

You know his work—Show Boat, Oklahoma!, Carousel, The King and I. But you don't really know Oscar Hammerstein II, the man who, more than anyone else, invented the American musical. Among the most commercially successful artists of his time, he was a fighter for social justice who constantly prodded his audiences to be better than they were.

The story of Donald Trump’s rise to power is the story of a buried American history - buried because people in power liked it that way. It was visible without being seen, influential without being named, ubiquitous without being overt. Sarah Kendzior’s Hiding in Plain Sight pulls back the veil on a history spanning decades, a history of an American autocrat in the making. In doing so, she reveals how our continual loss of freedom, the rise of consolidated corruption, and the secrets behind a burgeoning autocratic United States have been hiding in plain sight for decades.

In December of 1938, a chemist in a German laboratory made a shocking discovery: When placed next to radioactive material, a Uranium atom split in two. That simple discovery launched a scientific race that spanned three continents. In Great Britain and the United States, Soviet spies worked their way into the scientific community; in Norway, a commando force slipped behind enemy lines to attack German heavy-water manufacturing; and deep in the desert, one brilliant group of scientists was hidden away at a remote site at Los Alamos.

Thomas Edison was a famous American inventor in the late 1800s. His work with light bulbs got a lot of attention. Over time, many stories were told about this work, including that he invented the light bulb. But this isn’t true! Discover what’s real and what’s fiction.

We all know that encouraging curiosity and learning is crucial for our children's development, but it isn't always easy. Did you know that children who play while learning are more likely to retain the information they were taught? You don't have to sacrifice fun to encourage learning. That's why we created "Interesting Facts For Curious Kids" filled with challenging questions, fun facts, and interesting stories, your kids (and family!) will be entertained and learning for hours!

On March 29, 1516, the city council of Venice issued a decree forcing Jews to live in il geto - a closed quarter named for the copper foundry that once occupied the area. The term stuck. In this sweeping and original interpretation, Mitchell Duneier traces the idea of the ghetto from its beginnings in the 16th century and its revival by the Nazis to the present. As Duneier shows, we cannot understand the entanglements of race, poverty, and place in America today without recalling the history of the ghetto in Europe, as well as later efforts to understand the problems of the American city.

To solve one of the great mathematical problems of his day, Alan Turing proposed an imaginary computer. Then, attempting to break a Nazi code during World War II, he successfully designed and built one, thus ensuring the Allied victory. Turing became a champion of artificial intelligence, but his work was cut short. As an openly gay man at a time when homosexuality was illegal in England, he was convicted and forced to undergo a humiliating "treatment" that may have led to his suicide.

The end of Communism and breakup of the Soviet Union was a time of euphoria around the world, but Russia today is violently anti-American and dangerously nationalistic. So how did we go from the promise of those days to the autocratic police state of Putin's new Russia? The Invention of Russia reaches back to the darkest days of the Cold War to tell the story of the fight for the soul of a nation.

America is an urban nation. More than two thirds of us live on the three percent of land that contains our cities. Yet cities get a bad rap: they're dirty, poor, unhealthy, crime ridden, expensive, environmentally unfriendly. Or are they? As Edward Glaeser proves in this myth-shattering book, cities are actually the healthiest, greenest, and richest (in cultural and economic terms) places to live.

Little more than a century ago, the southern coast of California - bone-dry, harbor-less, isolated by deserts and mountain ranges - seemed destined to remain scrappy farmland. Then, as if overnight, one of the world’s iconic cities emerged. At the heart of Los Angeles’ meteoric rise were three flawed visionaries: William Mulholland, an immigrant ditch-digger turned self-taught engineer; D.W. Griffith, who transformed the motion picture from a vaudeville-house novelty into a cornerstone of American culture; and Aimee Semple McPherson, a charismatic evangelist.

In this account of Europe’s rise to world leadership in technology, Frances and Joseph Gies make use of recent scholarship to destroy two time-honored myths. Myth One: that Europe’s leap forward occurred suddenly in the “Renaissance,” following centuries of medieval stagnation. Myth Two: that Europe achieved its primacy through “Western” superiority.

What first prompted prehistoric man, sheltering in the shadows of deep caves, to call upon the realm of the spirits?And why has belief thrived ever since, leading us to invent heaven and hell, sin and redemption, and above all, gods?Religion reflects our deepest hopes and fears; whether you are a believer or, like Matthew Kneale, a non-believer who admires mankind's capacity to create and to imagine, it has shaped our world.

With the publication of Essay on the Principle of Population and its projection of food shortages in the face of ballooning populations, British theorist Thomas Robert Malthus secured a leading role in modern political and economic thought. In this startling new interpretation, Deborah Valenze reveals how canonical readings of Malthus fail to acknowledge his narrow understanding of what constitutes food production.

Jeevan Vasagar, former Singapore correspondent for the Financial Times, masterfully takes us through the intricate history, present and future of this unique diamond-shaped island one degree north of the equator, where new and old have remained connected. Lion City is a personal, insightful and essential guide to the city and how its remarkable rise is shaping East Asia and the rest of the world.
