The two previous books were intentionally easy reads as I was prepping to tackle this big boy and stick to my 1/week average. It is after all a summation of all important scientific knowledge known to mankind. Tectonic plates, astronomy, evolution, bacteria, the atom. All that and more.
I admit that when it comes to science I am an ignoramus. I consume a ton of politics, history and even psychology, but scientifically I’m the equivalent of the 11% of Americans that can’t even place their own country on the map.
Why don’t I care about science? I find people interesting, for one. I also don’t much care how scientists came to know something to be true, which is to say all of the computations required to arrive at a conclusion. I don’t know enough to value this work or have an opinion, so it is basically gibberish. Whether it is carbon dating or the theory of relativity, the end result is fascinating, the process less so. The other reason is pure vanity – thinking about the natural world makes me feel small. I am but one organism among trillions that have existed on Earth over 4 billion years and our planet is potentially just one of 1,000,000,000,000,000,000,000,000 in the universe. My body is an assemblage of atoms that will disperse and take other forms. The light I view from a star is actually 800 years old and my most important star, the sun, will eventually burn out entirely. It’s enough to make anyone feel insignificant, which is probably why most religions imagine a world centered around the Earth and humans.
Still, when learning more it appears we are extraordinarily lucky. It is totally possible the big bang might not have produced matter or that gravity could have collapsed the universe. The Earth could be a few degrees further from the Sun, rendering it a frozen wasteland. The atmosphere might not have arisen and cosmic rays would enter Earth, burning my flesh (or whatever little bit of algae or mollusk that might become me). Bacteria, asteroids, cooling or heating of the Earth, massive volcanic eruptions, neanderthals bashing homo sapiens to death with clubs. All would mean no me. If a piece of Earth hadn’t chunked off and reassembled as the moon the sun would be setting on me as I type this as a day would only be about 8 hours long. It isn’t fate that I’m here, just luck. I’m extremely fortunate for that and I’m grateful. That extreme fortuity makes me feel less small in the scheme of things.
This book is fantastic if you mostly want a history of scientific thought, with just a bare bones explanation as to how scientists arrived at their conclusions. Bryson sprinkles in the stories of the scientists themselves, which are often hilarious, bizarre, sad (those who pursued theories for their entire life that were wrong or those who were never recognized in their time) and often inspiring. Nearly every new discovery was viciously opposed as status quo scientists dug their heels into existing paradigms for reasons of inertia, power, money or lack of imagination. This book is great as it is as much a story of the humans who have uncovered some of the universe’s secrets as it is a list of what they found. We owe them all, even those who failed, a tremendous debt.
