WHEN SCIENCE STOOD STILL provides a glimpse into the challenges scientists can face when they propose ideas that fly in the face of current understanding. Detailing the work of Indian-born American astrophysicist Subrahmanyan Chandrasekhar, this beautifully illustrated book takes us through the highs and lows of his work, from his realization that some stars die by disappearing after a massive explosion to the ridicule he faced when he presented his ideas to other astrophysicists and his decision to leave the idea behind for decades until others were ready to accept his work. Not many science nonfiction books tug at the heartstrings, but this one definitely does.

This is such an inspiring, interesting story, sure to capture the imaginations of adults as well as children. A great lesson in not giving up and the importance of having the courage of your convictions. The story makes what might be a difficult topic understandable and interesting. Fascinating back matter goes into detail about Chandrasekhar’s life, the life and death of stars, and other topics.

It’s a revelation how much I learn from picture books! Shruthi Rao’s tale of a brilliant scientist who never gave up shines a light on one of the lesser known aspects of scientific research. Many concepts and ideas now accepted without question took many years to break through the beliefs and understandings of their day. And many of the people who made it most difficult for new ideas to emerge were scientists themselves, some who zealously guarded their own discoveries! Rao’s portrait of the Indian-born American Subrahmanyan Chandrasekhar as a deep thinker and problem-solver even as a child invites young readers to share his sense of wonder and determination. The illustrations do double duty, both portraying Chandra and his world with engaging specificity and presenting the science of black hole research in gorgeous detail. My favorite spread is of Chandra on the beach gazing up at the stars! Rao’s clear text makes even the most complex concepts understandable. This book will entice curious young scientists to follow their dreams, but is also a wonderful read for any child who seeks to rise above prejudice in all its forms.

This book is an excellent choice for the budding astrophysicist. It is a story of perseverance and courage, following scientist S. Chandrasekhar (known as Chandra) as he discovers scientific truths about black holes. In India, his theories are admired, and he publishes some of his work. He then is given a scholarship to England where he speaks to an important astrophysicist, Sir Arthur Eddinton, about his work. At first, Eddington listens, and even suggests Chandra stand for a presentation in front of other scientists. When he presents his theory of how black holes are formed, Eddinton makes fun of him and cuts down his theory. Although Chandra is betrayed and bewildered, he does not drop his theory or his profession. Instead, he goes to America where he becomes a well-respected professor. Eventually, his theory is proved correct, and he receives the Nobel Prize. What a great story, depicting how not giving up is always a good strategy. Illustrations by Srinidhi Srinivasan add to the delight of this book.

An inspiring story of not only an important discovery, but a personal story of a scientist's persistence and perseverance that will engage readers. Rao tells the compelling story of Subrahmanyan Chandrasekhar, popularly known as Chandra, who was an Indian-born American astrophysicist. He was just nineteen when, on the voyage to England, Chandra made a groundbreaking discovery. Chandra thought of applying Einstein's theory of relativity to stars because particles inside stars travel at speeds close to that of light. That is when his calculations suggested that some dying stars behave differently. And the concept of black holes was born! However, Chandra is devastated and humiliated when he presents his ideas to scientists in Europe and his theory is mocked (and a supposed supporter undercuts him). But almost fifty years later (after he's been an inspiring professor in the U.S.), he wins the Nobel Prize for his work. The last line of the story is powerful: "More than the recognition, what mattered to him was that, finally, the world saw the truth."

The book opens when a young boy, popularly known as Chandra, was fascinated by science and by the stars. The boy grew up and became an astrophysicist. He tried to share his ideas with others but at first they wouldn’t listen. “Science stood still” as Chandra’s ideas were largely ignored for decades. Still, he moved and earned recognition bit by bit. Then, with the development of the atomic bomb during WW2, suddenly his ideas about atoms and black holes resurfaced. Scientists worked together to realize that all along, Chandra was right. They studied together and found out more about the behavior of stars. Finally, science moved forward. This is a fascinating book about the incredible life of Chandra, how human resistance can stagnate science, and how working together can achieve great results. With lovely illustrations and a powerful message, this book is a wonderful addition to any shelf!

I don't understand physics. At all. Never have. Sad to say, I probably never will. Ever since i scored 34% on a grade 11 test and then quietly dropped the subject without informing my dad who was hoping for a medical doctor, I have quietly side-stepped the subject at every turn.

Which makes what Shruti has accomplished with WHEN SCIENCE STOOD STILL pretty amazing. I opened a book about physics. I got a basic understanding of how black holes are formed. And most importantly, I learned the history of a scientist who was scorned likely because of his cultural background, only to be proven right decades later. And I enjoyed it.

Not only is this a great story, the illustrations are incredibly captivating. The intro explains the title of the book and immediately draws you in. And the back matter provides additional information to pore over.

This is a great book for any child interested in physics or math. Highly recommended!

This book opened my mind almost as wide as the night sky! I was unaware of the story behind S. Chandrasekhar's brilliance and his remarkable accomplishments. The text within When Science Stood Still is accessible and carefully crafted so readers can understand the significance of the topic as well as S. Chandrasekhar's motivations, background, and personality. Readers will feel his deep disappointments and celebrate with him when his achievements are finally recognized. The illustrations transport us to the setting and grandeur of S. Chandrasekhar's vision. This beautiful STEM picture book offers an important piece of history and scientific achievement that everyone should know and understand.

[Laura Bontje · Rating 4 out of 5]

What a fascinating topic! There's a lot going on in this story, from the science of black holes to the aspirations of Subrahmanyan Chandrasekhar and his attempts to have his discoveries recognized. The illustrations are gorgeous, and I love the way that Srinidhi Srinivasan depicts things like an angry shadow admonishing Chandra, or Eddington ("a brilliant star in his field") shining like an actual star. Shruthi Rao has captured the sense of frustration that Chandra must have felt without losing the hope that all scientists need in order to keep moving forward. The back matter is packed with further information for young readers who'd like to learn more about the history and science behind the story.

[Heather Lang · Rating 5 out of 5]

I have a soft spot for inspiring picture book biographies about lesser-known people, and this story about Indian-born American astrophysicist Subrahmanyan Chandrasekhar (Chandra) did not disappoint! We follow Chandra on his emotional journey as he struggles to be taken seriously, but this passionate scientist doesn’t give up. Eventually he wins the Nobel Prize, fifty years after he first talked about stars disappearing. Now that’s perseverance! And astrophysics is a topic that can be challenging to present to young readers, but Rao makes it accessible and fascinating. Srinivasan’s illustrations are vibrant and expressive, and I loved learning more about Chandra and the life and death of stars in the comprehensive back matter.

[Megan Clendenan · Rating 5 out of 5]

An inspiring and fascinating biography about a brilliant young scientist who made an incredible discovery about stars. This book wonderfully showcases the perseverance that Subrahmanyan Chandrasekhar demonstrated for years, even as his ideas were rejected and ridiculed by other leading scientists. Shruthi Rao does a masterful job crafting the story in a way that’s accessible to young readers (even with so many advanced science concepts!), as well as conveying his emotional journey, fraught with frustration, but also infused with a never-give-up attitude. A wonderful story and so important to share with young readers. The back matter is also fascinating. Highly recommended.

[Elizabeth Tracy · Rating 5 out of 5]

Illustrator Srinidhi Srinivasan and author Shruthi Rao combine forces beautifully to tell the empowering story of Subrahmanyan Chandrasekhar (Chandra), who was before his time when he predicted the existence of black holes – but he was summarily dismissed. Nevertheless, Chandra continued his groundbreaking work in the field of astrophysics until finally, decades later, the next generation of scientists recognized and expanded upon his contributions so that science could leap forward instead of standing still. WHEN TIME STOOD STILL is a brilliant and inspiring story (and a feast for the eyes). I highly recommend adding it to your picture book collection.

[Maria Antonia · Rating 5 out of 5]

A wonderful look at the perseverance of a young scientist, even in the face of other leading scientists rejecting his ideas. He kept on and would eventually be proved correct! This book is perfect for those interested in the history behind the discovery of black holes. I found the story fascinating. The book includes a note from the author.

Love the illustrations, especially the blues depicting space.

It's a good lesson for all of us to be careful not to let science stand still, but also to persevere even when others dismiss us.

[Christine Zandt · Rating 5 out of 5]

A book that truly encourages perseverance as we see the main character come up with a brilliant idea (that turns out to be true) but the lead men in science rejected and ridiculed him. Kids will immediately understand what that feels like and will root for Chandrasekhar to finally be recognized for his amazing discoveries. In classrooms, this story opens the door to many discussions such as how science can "stand still." The art is beautifully done and serves as a perfect complement to the text.

[Sandhya Acharya · Rating 5 out of 5]

A beautiful tribute to a brilliant scientist, this story is packed with information presented in an exciting way, sure to appeal to young readers. The story introduces us to the concept of black holes and the mysteries of space while also highlighting the arduous path Subramaniam Chandrashekhar had to take. They will see how the scientific community thrives by learning from each other - building on years of research from scientists who came before them - and understand what happens when prejudice excludes some.

[Nora Nickum · Rating 5 out of 5]

A fascinating and inspiring tale of innovation and persistence in the face of social pressure, doubt, and discrimination. Subrahmanyan Chandrasekhar, popularly known as Chandra, deduced a new theory of dying stars, but it took decades for others to listen and realize he was right. This book has beautiful art and the author has included rich back matter with additional detail about Chandra's life, the science, and a timeline of other black hole related facts.

[Katie Furze · Rating 5 out of 5]

Wow – this picture book bio about ‘Chandra’ the astrophysicist who predicted black holes packs quite a punch! The story is riveting and heartrending at the same time. The way this young and brilliant scientist born in India was treated by his peers in England brought tears to my eyes. The back matter, which explains more about the background and significance of his discovery, is also excellent. Read it!

[Leslie Barnard Booth · Rating 5 out of 5]

This stunning must-read book tells the absorbing story of scientist Subrahmanyan Chandrasekhar's discovery of black holes.
