Let the Great World Spin by Colum McCann

In the dawning light of a late-summer morning, the people of lower Manhattan stand hushed, staring up in disbelief at the Twin Towers. It is August 1974, and a mysterious tightrope walker is running, dancing, leaping between the towers, suspended a quarter mile above the ground. In the streets below, a slew of ordinary lives become extraordinary in bestselling novelist Colum McCann’s stunningly intricate portrait of a city and its people.

Let the Great World Spin
is the critically acclaimed author’s most ambitious novel yet: a dazzlingly rich vision of the pain, loveliness, mystery, and promise of New York City in the 1970s.

Corrigan, a radical young Irish monk, struggles with his own demons as he lives among the prostitutes in the middle of the burning Bronx. A group of mothers gather in a Park Avenue apartment to mourn their sons who died in Vietnam, only to discover just how much divides them even in grief. A young artist finds herself at the scene of a hit-and-run that sends her own life careening sideways. Tillie, a thirty-eight-year-old grandmother, turns tricks alongside her teenage daughter, determined not only to take care of her family but to prove her own worth.

Elegantly weaving together these and other seemingly disparate lives, McCann’s powerful allegory comes alive in the unforgettable voices of the city’s people, unexpectedly drawn together by hope, beauty, and the “artistic crime of the century.” A sweeping and radical social novel, Let the Great World Spin captures the spirit of America in a time of transition, extraordinary promise, and, in hindsight, heartbreaking innocence. Hailed as a “fiercely original talent” (San Francisco Chronicle), award-winning novelist McCann has delivered a triumphantly American masterpiece that awakens in us a sense of what the novel can achieve, confront, and even heal.

Why Does Everything In The Universe Spin?

Why Does the Earth Rotate?

Every day, the Earth spins once around its axis, making sunrises and sunsets a daily feature of life on the planet. It has done so since it formed 4. But why does it rotate at all? The Earth formed out of a disk of gas and dust that swirled around the newborn sun. In this spinning disk, bits of dust and rock stuck together to form the Earth, according to Space.

We spend our lives on a spinning globe -- it takes only 24 hours to notice that, as night follows day and the cycle repeats. But what causes Earth to rotate on its axis? The answer starts with the forces that formed our solar system. A fledgling star gathers a disk of dust and gas around itself, said Kevin Luhman, an assistant professor of astronomy at Penn State. As things coalesce, the star's gravitational orbit sets that dust and gas to spinning. As the clump collapses on itself it starts spinning faster and faster because of something called conservation of angular momentum. Figure skaters exploit this law when they bring their arms closer to their bodies to speed up their rate of spin, Luhman explained.

Earth's rotation is the rotation of Planet Earth around its own axis. Earth rotates eastward , in prograde motion. As viewed from the north pole star Polaris , Earth turns counterclockwise. This point is distinct from Earth's North Magnetic Pole. The South Pole is the other point where Earth's axis of rotation intersects its surface, in Antarctica.

Why the spin continues

In a classic episode of this video series, I did the calculations for how fast the Earth is spinning. Why is everything in the Solar System spinning? And why is it mostly all spinning in the same direction? Same with the Sun, Mars and most of the planets. Then, it took some kick, like from the shockwave from a nearby supernova, and this set a region of the cold gas falling inward through its mutual gravity. As it collapsed, the cloud began to spin.

This is an article from Curious Kids , a series for children. All questions are welcome — serious, weird or wacky! To answer this tricky question, we have to look back in time to when the Earth was born, 4. We have to ask: why did the Earth start spinning in the first place? When our solar system formed out of a gas cloud, called a nebula, there was lots of dust and gas coming together due to the force of gravity. The dust and gas was already moving around in a circle.

As a father and a science lover I was dumbfounded when my 7yr old son asked me "What makes our earth turn rotate? He then asked "Did it start a long time ago and it just keeps turning or is something pushing it to turn"? How does the Earth continue to rotate around its axis? Where does the energy to keep it moving come from? Our everyday experience teaches us that an object must be "pushed" by a force in order to keep it moving. Otherwise, it will slow down and eventually stop.
