Why am I passionate about this?

I have been increasingly interested in astrophysics since I was six years old. My mother hooked me on reading at five by stopping novels at critical points and urging me to continue. I’ve ever since read a broad range of books. I stumbled upon Dr. Loren Eiseley in the early 1970s and enjoyed his books immensely. As soon as a book by Dr. Carl Sagan was published, I wanted to read it. As I’ve grown older, I try not to think that ‘peak humanity’ is behind us–and books such as Sagan, Eiseley, and Rovelli offset that potentially depressing thought and provide solid encouragement.

The books I picked & why

Book cover of Pale Blue Dot: A Vision of the Human Future in Space

Eric M. Schlegel Why did I love this book?

For me, this book melded many ideas I had as I grew up on humanity’s place in the Universe. Dr. Sagan’s writing just pulled many of my ideas and understanding into one strong framework.

As with many of the books I recommend, Sagan's writing showed me that I can do science and still remain grounded without my ego expanding faster than the universe!

By Carl Sagan, Ann Druyan,

Why should I read it?

1 author picked Pale Blue Dot as one of their favorite books, and they share why you should read it.

What is this book about?

“Fascinating . . . memorable . . . revealing . . . perhaps the best of Carl Sagan’s books.”—The Washington Post Book World (front page review)

In Cosmos, the late astronomer Carl Sagan cast his gaze over the magnificent mystery of the Universe and made it accessible to millions of people around the world. Now in this stunning sequel, Carl Sagan completes his revolutionary journey through space and time.

Future generations will look back on our epoch as the time when the human race finally broke into a radically new frontier—space. In Pale Blue Dot, Sagan traces the spellbinding history…


Book cover of The Demon-Haunted World: Science as a Candle in the Dark

Eric M. Schlegel Why did I love this book?

As with my first recommendation, this book pulls together many of the ideas about people’s beliefs and thinking that I had growing up.

While I read it in ‘early middle age,’ it again synthesized a good many questions across a very broad range of topics. In the process, the book helped to solidify my own thoughts about the world in which we live and how to learn more about our Universe.

By Carl Sagan, Ann Druyan,

Why should I read it?

7 authors picked The Demon-Haunted World as one of their favorite books, and they share why you should read it.

What is this book about?

A prescient warning of a future we now inhabit, where fake news stories and Internet conspiracy theories play to a disaffected American populace

“A glorious book . . . A spirited defense of science . . . From the first page to the last, this book is a manifesto for clear thought.”—Los Angeles Times

How can we make intelligent decisions about our increasingly technology-driven lives if we don’t understand the difference between the myths of pseudoscience and the testable hypotheses of science? Pulitzer Prize-winning author and distinguished astronomer Carl Sagan argues that scientific thinking is critical not only to the…


Book cover of The Firmament of Time

Eric M. Schlegel Why did I love this book?

I read practically everything anthropologist Dr. Eiseley wrote because he showed me that I did not have to be ‘robotic’ to enjoy science.   

One of the best parts of the book involves a physicist and a turtle. I really enjoyed reading about ideas similar to those of Dr. Sagan but from an anthropologist’s view.

By Loren Eiseley,

Why should I read it?

1 author picked The Firmament of Time as one of their favorite books, and they share why you should read it.

What is this book about?

Loren Eiseley examines what we as a species have become in the late twentieth century. His illuminating and accessible discussion is a characteristically skillful and compelling synthesis of hard scientific theory, factual evidence, personal anecdotes, haunting reflection, and poetic prose.


Book cover of The Unexpected Universe

Eric M. Schlegel Why did I love this book?

Eiseley first became known for his book The Immense Journey. I enjoyed that book, but I enjoyed this one considerably more, perhaps because its context was closer to my interests.

There were paragraphs within this book where my thoughts were right there on the page. I found that to be very exciting.

By Loren Eiseley,

Why should I read it?

2 authors picked The Unexpected Universe as one of their favorite books, and they share why you should read it.

What is this book about?

Drawing from his long experience as a naturalist, the author responds to the unexpected and symbolic aspects of a wide spectrum of phenomena throughout the universe.Scrupulous scholarship and magical prose are brought to bear on such diverse topics as seeds, the hieroglyphs on shells, lost tombs, the goddess Circe, city dumps, and Neanderthal man. AUTHOR: Loren Eiseley's many works include The Night Country, The Invisible Pyramid, The Immense Journey and The Firmament of Time, all available in Bison Books editions. He worked at the University of Pennsylvania until his death.


Book cover of Reality Is Not What It Seems: The Journey to Quantum Gravity

Eric M. Schlegel Why did I love this book?

I enjoyed this book because I’ve had many questions over the past decade or so about quantum physics and the (eventual) redefinition of gravity and spacetime.

Rovelli’s book helped me see connections between articles I’ve read and only partially understood. Those connections helped me communicate more clearly with people attending a science outreach event—'more clear communications' is better for everyone.

By Carlo Rovelli, Simon Carnell (translator), Erica Segre (translator)

Why should I read it?

2 authors picked Reality Is Not What It Seems as one of their favorite books, and they share why you should read it.

What is this book about?

'The physicist transforming how we see the universe' (Financial Times)

'An utter joy' (Adam Rutherford)

'A hugely engaging book... Rovelli is a charming, thought-provoking tour guide' (Manjit Kumar Prospect)

Do space and time truly exist? What is reality made of? Can we understand its deep texture?
Scientist Carlo Rovelli has spent his whole life exploring these questions and pushing the boundaries of what we know. In this mind-expanding book, he shows how our understanding of reality has changed throughout centuries, from Democritus to loop quantum gravity. Taking us on a wondrous journey, he invites us to imagine a whole new…

Elephant Safari

Book cover of Elephant Safari

Peter Riva Author Of Kidnapped on Safari

New book alert!

Why am I passionate about this?

I have been to, and loved, North, Central, and especially East Africa for over fifty years. Only six times have I been to Africa on holiday; more often, perhaps twenty or more times, as a television producer. Working in Africa gains a perspective of reality that the glories of vacation do not. Each has its place, each its pitfalls like stalled plane rides with emergency landings in the bush or attacks by wildlife. But, in the end, the magic of the “otherness,” what an old friend called “primitava” captures one’s soul and changes your life.

Peter's book list on the otherness that few get to experience

What is my book about?

Keen to rekindle their love of East African wildlife adventures after years of filming, extreme dangers, and rescues, producer Pero Baltazar, safari guide Mbuno Waliangulu, and Nancy Breiton, camerawoman, undertake a filming walking adventure north of Lake Rudolf, crossing from Kenya into Ethiopia along the Omo River, following a herd of elephant making their annual migration.

Stumbling onto an elephant poaching, the team become embroiled in true financing of terrorism for al Shabaab –ivory sales–and are determined to stop the slaughter at any cost. Ivory trade financing terrorism involves UN refugee camps with two hundred thousand displaced Somali persons, powerful…
