A Little Book about the Big Bang


Tony Rothman - 2022
    In A Little Book about the Big Bang, physicist and writer Tony Rothman guides expert and uninitiated readers alike through the most compelling mysteries surrounding the nature and origin of the universe.Cosmologists are busy these days, actively researching dark energy, dark matter, and quantum gravity, all at the foundation of our understanding of space, time, and the laws governing the universe. Enlisting thoughtful analogies and a step-by-step approach, Rothman breaks down what is known and what isn't and details the pioneering experimental techniques scientists are bringing to bear on riddles of nature at once utterly basic and stunningly complex. In Rothman's telling, modern cosmology proves to be an intricate web of theoretical predictions confirmed by exquisitely precise observations, all of which make the theory of the big bang one of the most solid edifices ever constructed in the history of science. At the same time, Rothman is careful to distinguish established physics from speculation, and in doing so highlights current controversies and avenues of future exploration.The idea of the big bang is now almost a century old, yet with each new year comes a fresh enigma. That is scientific progress in a nutshell: every groundbreaking discovery, every creative explanation, provokes new and more fundamental questions. Rothman takes stock of what we have learned and encourages readers to ponder the mysteries to come.

The First Astronomers: How Indigenous Elders read the stars


Duane Hamacher - 2022
    We no longer look to the stars to forecast the weather, predict the seasons or plant our gardens. Most of us cannot even see the Milky Way. But First Nations Elders around the world still maintain this knowledge, and there is much we can learn from them.These Elders are expert observers of the stars. They teach that everything on the land is reflected in the sky, and everything in the sky is reflected on the land. How does this work, and how can we better understand our place in the universe?Guided by six First Nations Elders, Duane Hamacher takes us on a journey across space and time to reveal the wisdom of the first astronomers. These living systems of knowledge challenge conventional ideas about the nature of science and the longevity of oral tradition. Indigenous science is dynamic, adapting to changes in the skies and on Earth, pointing the way for a world facing the profound disruptions of climate change.

Astroquizzical: Solving the Cosmic Puzzles of Our Planets, Stars, and Galaxies: The Illustrated Edition


Jillian Scudder - 2022
    We are here on Earth because billions of years ago the Big Bang created the atoms that, over unimaginable periods of time, formed the stars and galaxies. Generations of stars that burned, exploded, or collided long before our planet was formed created the carbon of our bodies and the iron in our blood. In Astroquizzical, astrophysicist Jillian Scudder takes readers on a curiosity-driven journey through outer space, traveling back in time from Earth to the stars and galaxies to the cosmic explosions of the Big Bang.Scudder proceeds--astroquizzically--question by question, answering and explaining such queries as "What color is the universe?," "Do all planets spin the same way?," and "How many galaxies are there?" Along the way, she proposes a series of thought experiments, including "What would happen if we split the sun in half?" and "What happens to time dilation at the speed of light?" She covers meteors, the aurora, and the Moon (Earth's cosmic companion); Jupiter's stripes and Pluto's mountains; red dwarfs, brown dwarfs, and white dwarfs; the deaths of stars and the abundance of galaxies; and much more. Striking color images illustrate astrophysical marvels.
