Manasvi Lingam Bridges Gap Between Introductory and Graduate Astrobiology Education with New Textbook
Astrobiologist Manasvi Lingam, assistant professor of aerospace, physics and space sciences at Florida Tech, authored a new astrobiology textbook to serve as a resource for the rapidly growing multidisciplinary field. “From Stars to Life: A Quantitative Approach to Astrobiology,” published by Cambridge University Press, is primarily geared toward upper-level undergraduate and graduate students studying astrobiology, Lingam says. Co-authored by astrophysicist Amedeo Balbi (University of Rome), the book’s 15 chapters cover topics from the Big Bang theory to planetary habitability to the future of humankind. The book also includes practice problems that involve modern developments like GenerativeAI (e.g., ChatGPT). Lingam explained how he came up with the new textbook and why it can help shape astrobiology programs like Florida Tech’s. What inspired this textbook? Manasvi Lingam: [Florida Tech] was the first university in the whole world to start an undergraduate astrobiology major. We have a strong connection to the field. But it turns out, every time I teach the subject, I don’t have a textbook to use. I have my first book, which is “Life in the Cosmos,” but it’s 1,100 pages. It’s for graduate students. It’s not going to work for them. Every time I was trying to cobble together resources from different places. My co-author has the same problem except that he’s been teaching [astrobiology] for even longer, for 20 years. He doesn’t have a textbook either. There’s this old saying in English: if you want something done right, do it yourself. We decided, well, might as well just try to write it ourselves. That’s how it came to be. How does this textbook bridge the gap between introductory readings and graduate-level material? ML: Right now, there’s pretty much only one class of textbooks for astrobiology, and those are written for freshman- or sophomore-level undergraduates. There’s this emphasis on a broad overview but at an extremely qualitative level and sometimes offering somewhat weak explanations for various specific phenomena, such as, “Why did Mars lose its atmosphere? It just got eroded over time.” These kinds of limitations. Graduate literature is very specialized, oriented towards whatever subfield one is studying in astrobiology. You can have a whole book on the origin of life. You can have a whole book on just Mars. You can have a whole book on Titan and so on. The aforementioned introductory textbooks that exist are very broad, but they don’t really offer a tool to actually get started doing research in the more specialized field. There was this vital need to bridge the gap. That’s what this book is meant to do. How did you decide what content to include and what not to include? ML: This field begins almost with the Big Bang – the start of the universe – which is when the first elements were formed, including elements that are widespread in life like hydrogen. This tale begins almost with the beginning of the universe. It is a tale that is still ongoing and is going to unfold for trillions of years into the future. But, there was so much material to include in principle. We had to be quite selective about what topics to include. There are a number of courses that are taught around the world on this topic. We looked at dozens of them to find the common core within all of them, and then expanded on that core. That’s what constitutes our table of contents. While writing the textbook, how did you grow as a researcher and an educator? ML: There’s this implicit understanding in academia that if you can write something down clearly, and if you can articulate something clearly, that’s when you can really say you understand it. Often you can’t articulate what you need to say coherently and succinctly if it’s something very big. That’s what, of course, astrobiology is. In the process of writing the book as an educator, I think I was really able to see how various domains linked to each other. For instance, modulations of, say, the Earth’s climate that were driven not just by changes on Earth (including life itself!), but also by changes in the sun, by changes in the orbits of other solar system planets, but also phenomena that were taking place hundreds of light years away in the galaxy. You really see that everything is connected – there are hidden links to each other. I think that helped me discover the magic of the universe, so to speak, even more. From a research standpoint, there were some areas that I have not worked in a lot, but by writing this book, I’ve gotten a better understanding of those areas, like, say, Mars, and also certain microbiological and astrophysical aspects as well. I think that has provided new ideas that I hope to explore in the future. What do you want readers to learn throughout the book, and what should they walk away with? ML: What we want to do is build a holistic integrated understanding of different phenomena pertaining to life in the universe, but at a quantitative level, and still retain breadth without sacrificing depth in the process. It won’t necessarily make students ready for research because it’s still primarily an undergrad textbook, but it will give them a comprehensive understanding of how various processes are intertwined with each other. We want people to see the big picture without missing out on the detail, and to appreciate the beauty of life, Earth, the solar system, the Milky Way and the universe. Lingam plans to start teaching from this textbook in Spring 2025. The textbook is available for purchase on Amazon.
