 This week’s book review


Title: Mapping the Heavens: The Radical Scientific Ideas That Reveal the Cosmos
Author: Priyamvada Natarajan
Publisher: Yale University Press
Publication Year: 2016
Pages: 336

Priyamvada Natarajan’s Mapping the Heavens is more than just a book about astronomy; it’s an invitation to join a journey that has spanned centuries, driven by humanity’s insatiable curiosity to understand the universe. Natarajan, a theoretical astrophysicist with a deep passion for her field, takes readers on a compelling voyage through the most revolutionary ideas that have reshaped our understanding of the cosmos.


What sets Mapping the Heavens apart is Natarajan’s ability to distill complex scientific concepts into narratives that are both engaging and accessible. She navigates through the intricacies of cosmology, from the mysterious nature of dark matter and dark energy to the mind-bending implications of black holes, with the ease of a seasoned guide who knows how to make even the most abstract ideas feel tangible.

Natarajan’s writing is clear and eloquent, but what truly humanizes her work is the way she intertwines the history of these ideas with the stories of the people behind them. From Galileo’s groundbreaking observations to the pioneering work of contemporary scientists, she highlights how each new discovery was not just a triumph of intellect, but also a testament to human perseverance and the willingness to challenge the status quo.

One of the most striking themes in Mapping the Heavens is the idea that science is not a static collection of facts but an evolving narrative shaped by both successes and failures. Natarajan deftly illustrates how each major breakthrough in cosmology often began with a question that defied conventional wisdom. Whether it was the controversial acceptance of heliocentrism, the debate over the expansion of the universe, or the recent discovery of gravitational waves, Natarajan shows how the history of cosmology is one of continual revision and refinement.

This theme resonates deeply, especially in an era where scientific consensus is sometimes mistaken for absolute truth. Natarajan reminds us that science is, at its core, a process of discovery, one that is inherently uncertain and always subject to change as new evidence comes to light.

Beyond the scientific content, Mapping the Heavens also provokes readers to reflect on the larger philosophical questions that arise from our exploration of the cosmos. Natarajan touches on the profound sense of wonder and humility that comes with realizing just how vast and mysterious the universe truly is. She explores how these discoveries challenge our perceptions of our place in the cosmos, forcing us to confront the possibility that we are just a small part of a much larger, perhaps incomprehensible, whole.

This reflective aspect of the book is particularly poignant. Natarajan doesn’t shy away from addressing the emotional and existential implications of cosmology. She acknowledges that the vastness of the universe can be both awe-inspiring and daunting, but she also celebrates the beauty of human curiosity — the drive that has led us to ask these big questions in the first place.

While Mapping the Heavens is an exemplary work of science communication, it is not without its challenges for the reader. The book assumes a certain level of familiarity with basic astronomical concepts, which might make some sections more challenging for those who are completely new to the field. Natarajan’s clear explanations and the book’s well-organized structure help mitigate this, making it approachable even for those who might initially feel out of their depth.

Some readers might find themselves wanting more depth in certain areas. Given the vast scope of the subject matter, there are moments when the book moves quickly through topics that could each warrant their own detailed exploration. This is a minor critique in the context of Natarajan’s broader goal — to provide a sweeping overview of the radical ideas that have shaped our understanding of the cosmos.

Mapping the Heavens is a remarkable achievement. It’s a book that not only informs but also inspires. Natarajan’s deep knowledge, combined with her passion for the subject and her skill as a storyteller, makes this a must-read for anyone who has ever looked up at the night sky and wondered about the mysteries of the universe.

Mapping the Heavens is as much about the human spirit as it is about the cosmos. It’s a celebration of our collective journey to understand the universe — a journey marked by curiosity, creativity, and a relentless drive to push beyond the boundaries of what we know. For anyone with a curious mind and a love for the stars, Priyamvada Natarajan’s book is an invitation to explore the cosmos in a way that is both deeply educational and profoundly moving.

OCI Object Storage: Copy Objects Across Tenancies Within a Region

This post was developed jointly with Mohamad Charaf, Oracle Enterprise Cloud Architect. If you have two tenancies in the same region, and you want to copy data that is stored in Object Storage from one tenancy to the other without making the buckets public, this action requires some additional types of identity and access management (IAM) policies. This blog post walks you through how to create these policies. For this example, the source tenancy is named ACMEBMCS and the destination tenancy is named ACMEOCISA. In ACMEBMCS, the Object Storage buckets are in the benchmark compartment. In ACMEOCISA, the target compartment is oracleexa . The follow...

Religious Perspectives on Artificial Intelligence: My views

  I am an Atheist. Born in a Hindu family, I have experimented with Christianity and Buddhism. Jokingly, I describe my journey from Many Gods to One and then None. I followed Hinayana Buddhism for a long time. Lately, I have been studying Lokayata/Carvaka school of the Hindu Darsana (philosophy). I like to be identified as a Hindu Atheist. Why Hindu? Because my birthplace is on the east side of the River Indus.

How MSPs Can Deliver IT-as-a-Service with Better Governance

 Sanjay Basu As a solutions architect, I often support partners who deliver managed IT services to their end customers. Similarly, I work with large enterprises who manage IT for multiple business units. One of the most frequent requests I get is for best practices on how to align Oracle Cloud Infrastructure solutions and Identity and Access Management (IAM) policies with business-specific governance use cases. For enterprise customers, this means having better control over usage costs across multiple business units. For managed service providers (MSPs), this involves having better cost governance over the IT environments that they manage for end customers in their Oracle Cloud Infrastructure tenancy. This post is structured like a case study, in which an example enterprise customer, ACME CORP's Central IT team, faces the following business challenge: How do they enable their departmental IT stakeholders, and the operators within those departments, to have the aut...
