Book review – Planetary Accounting: Quantifying How to Live Within Planetary Limits at Different Scales of Human Activity

7-minute read

What I am about to write is probably going to upset many people, but… I am growing frustrated with the narrative of much of the environmental movement. Taking to the streets to protest and demand change, to “do something!”, is all fine and dandy, but it is also a bit hypocritical. It fosters a narrative in which the onus is always on others and it begs the counter-question: “what are you willing to give up?”. That is the hard question.

There, I said it. You have the option to stop reading now.

In all seriousness, if we want to avert dangerous climate change or allow forests to recover from deforestation, how much change is enough? How much are we allowed to consume? Planetary Accounting will not offer you final prescriptive answers, but it is an important first step in quantifying per capita quota for what each of us can consume and pollute without it costing the planet.

Book review – Universe in Creation: A New Understanding of the Big Bang and the Emergence of Life

7-minute read

Did life arise merely by accident? Many scientists feel uncomfortable with talk of goal-directedness and greater plans, as it reeks more of religion and theology than rational explanation. And with creationists lurking, the risk of “smuggling God in through the back door” under scientific pretences (as Richard Dawkins put it) is something to be wary of. Without descending into this territory, Universe in Creation might skirt dangerously close to it for some. In turns lyrical, unsettling, and, yes, speculative, this book argues that life may be written into the most basic laws of nature.

Book review – Something Deeply Hidden: Quantum Worlds and the Emergence of Spacetime

7-minute read

I guess it was inevitable that in my wider reading on subjects such as astronomy and physics I would eventually bump into quantum mechanics. Where I have encountered it so far, I have admitted it went straight over my head. It might thus seem foolhardy for a biologist to try and tackle a book like this. Then again, the hallmark of good communicators is that they make complex topics understandable. And theoretical physicist Sean Carroll’s previous books have been lauded, some even winning prizes. Are you ready to get down and dirty with quantum mechanics?

Book review – Gravity’s Century: From Einstein’s Eclipse to Images of Black Holes

When the movie Interstellar was released in 2014, I thought its depiction of a black hole was one of the most hauntingly beautiful scenes. And with input from prominent astrophysicist Kip Thorne, there was plenty of science to this piece of science fiction (see The Science of Interstellar). Amazingly, we only had to wait five more years for an actual image of a black hole – or really its event horizon – to be published. But these astounding images have been a long time coming. With Gravity’s Century, science writer Ron Cowen traces the story back to Albert Einstein and provides an accessible and compact overview of the century-long quest in physics to better understand gravity.

Book review – Exoplanets: Hidden Worlds and the Quest for Extraterrestrial Life

Humans have been gazing at the stars since times immemorial. Once we understood what stars were, and that our planet together with others circled one such star, it was only a small step to think that there must be other planets outside of our Solar System. But only in the last 25 years have we been able to start finding these so-called exoplanets. Astronomer Donald Goldsmith here promises, and delivers, an introduction that even an astronomy novice such as myself could understand and thoroughly enjoy.
