Lab Girl

Lab Girl by Hope Jahren (2016)

Hope Jahren is an accomplished award-winning scientist, and her memoir is filled with stories from her professional and personal life. From her rural upbringing with stoic parents, to her many adventures in the field, she talks about what it's like to be a woman working in a male-dominated field and about her longtime friendship with a fellow scientist and outcast named Bill. Her stories alternate with short chapters of scientific content about plants and trees.

Jahren grew up in her father's lab, becoming comfortable at a young age with the equipment and other trappings of scientific life. As much as she loves the work, she doesn't gloss over the challenges - funding is a constant source of anxiety, as is the uphill battle of trying to achieve respect in the field, especially if you're seen as an outsider. From the beginning, there were few women in her field and she had to fight stereotypes and convince her peers that she was serious. I wish she had followed this thread a bit more in the book though - she talks about it a lot at the beginning, but later she didn't discuss how being a woman in science changed, or didn't change, and how it may have affected her later in her career.

Her friendship with Bill was a large part of the story. He was pretty stand-off-ish and others didn't take to him the way Jahren did. He was obviously poor and socially awkward, but brilliant, and they became very close friends. He often lived in a vehicle or in a lab, though eventually he secured more stable housing. It was an unusual relationship; they worked together and when Jahren would move away for another job she would take him with her so they could keep working together. It was unclear how she logistically made this happen, but I get the idea that she was given a certain amount of money that would cover hiring lab assistants and that's how she paid him. At any rate, I love how close they were, how they helped each other, and the fun adventures they had on their field trips. We could use more positive portrayals of relationships.

Interestingly, she came across as a total workaholic early in the book and everything was focused on her career and friendship with Bill, and then suddenly she begins a romantic relationship, gets married very quickly, and has a baby. It was a bit jolting. She had made maybe one mention earlier in the book about dating and somehow I was quite shocked that she chose to have a child. The parts about being a mother were so incongruous with the rest of the book, and I still liked these parts, I just think that maybe the different threads of her story weren't woven together well. It's the same for the sections in which she talks about her bipolar disorder - this was a bit more woven in with the parts about motherhood, but I still have a lot of questions about how it may have affected her work.

I learned a lot about plants and trees from the short chapters that focused on botany. Her descriptions of the process of trees shedding their leaves and how plants are affected by things that happened when they were just seeds made me think about plants as truly being alive in a way I hadn't considered before. We think of plants as being so passive just because they don't move in a way that we can see, but they really aren't passive at all. I've been sort of interested in Peter Wohlleben's popular book The Hidden Life of Trees for a while, and now I'm even more likely to eventually read it.

I've seen this book on a lot of "best of" lists and one of my coworkers personally recommended it as well. I found a lot to like here and generally enjoyed reading it, though I do think it was a bit disjointed and lost some of the thematic threads at various points. But overall, I liked it and it gave me a lot to think about. It's only near the end of the book that she mentions the importance of writing to her, and it's true that her writing is quite beautiful, especially when describing the trees and other plants about which she is so passionate. Hopefully this means we'll see more books from her in the future.

Seven Brief Lessons on Physics

Seven Brief Lessons on Physics by Carlo Rovelli (2016)

As the title suggests, this very short book (81 pages without the index) contains seven lessons on physics. We learn about general relatively, quantum mechanics, particles, gravity, black holes, the architecture of the universe, and the role of humans in all of this. Each chapter is like a simple but beautiful essay on the topic at hand, though later chapters do build on the information that came before.

I am not a science person. Although I was generally a good student in high school, I barely passed my science classes and never felt like I really understood them. In college I took two sciences, one of which I found really interesting (Marine Biology) yet was shocked every time I sat down to take an exam because it seemed like it was for a different class than the one I was experiencing. As for physics, I lasted one quarter in high school - not even a semester - before dropping it to take music. (Despite how upset my guidance counselor was about this decision, it is one I have never regretted. My senior year music teacher was awesome. More than 25 years later we're even friends on Facebook.)

My point is that science is something that interests me in a documentary-about-owls kind of way not an understanding-astrophysics kind of way. This book wasn't at all what I had in mind when I picked science as a category on my 2017 Personal Reading Challenge. But a coworker mentioned hearing positive reviews of this book and considering how short it is I decided it was worth a try. Because the truth is that I want to understand these concepts. I want to understand the universe I live in. I even tried watching Cosmos at one point and managed to get through a handful of episodes before losing interest. Understanding difficult abstract concepts is not something I put a lot of time or effort into.

But Rovelli approaches these topics in a way that geared towards the layperson, and what makes this book truly stand out is just how beautifully he writes. You can't help but by infected by his sense of wonder at the universe as you read these essays, even if you don't grasp every single thing. And I definitely didn't.

I am still thinking about a sentence very early in the book illustrating how time passes more quickly higher up: "If a person who has lived at sea level meets up with his twin who has lived in the mountains, he will find that his sibling is slightly older than he." I understand time passing differently for someone who is in space, but surely these two brothers are not separated by more than a few time zones? But I moved on through the book, getting what I could out of it and not letting myself get stuck on the bits that were, for me, impossible to grasp.

It was easy to get through a book which such lovely passages as this one:

"A handful of types of elementary particles, which vibrate and fluctuate constantly between existence and nonexistence and swarm in space, even when it seems that there is nothing there, combine together to infinity like the letters of a cosmic alphabet to tell the immense history of galaxies; of the innumerable stars; of sunlight; of mountains, woods, and fields of grain; of the smiling faces of the young at parties; and of the night sky studded with stars."

The whole book is like that. It's like a love poem to science.

Now I'm under no illusion that I have actually learned everything in this book. Already I'm forgetting what I've read. But I do feel more confident about reading other books or articles on scientific topics because I know now that it's possible to for me to understand it. I just need to find sources of this information from those who express themselves as simply and beautifully as Carlo Rovelli.
