“Small World” (or “Nexus”) – Mark Buchanan

It was a mistake to read both Barabási’s “Linked” and this book by science journalist Mark Buchanan. At least in such a short space of time, but I’m tempted to say you’ll really ever only need one or the other. Published within a few months of each other in 2002, not only do these two books cover exactly the same topic (small world, scale-free networks in everday life) but they use the same anecdotes (lame Bill Clinton jokes, Internet hacker stories, the excitement of having an Erdös number – mine is 4!) and even some of the same chapter titles. I can only imagine how mortifying it must have been to find out about each other.

As this review must necessarily be a comparison to the book I read first, let me just say they both have slightly different focal points. Although both authors are physicists by training, Buchanan gives a little more detail about the biological networks found, like the neural connections of C.elegans, while Barabási concentrates more on his own playground – the internet and WWW.

Overall, Buchanan’s style surprisingly is a little less readable than Barabási’s, or maybe I was just not as tolerant the second time round. There is quite an abstract chapter about rivers and the modelling of their meandering course to the sea and Small World is longer without saying much more than Linked.

To be fair, I would still recommend this book as an introduction to network theory. I just felt a little cheated.

“Is Pluto a planet?”, David Weintraub

No, apparently. Or at least there isn’t a meaningful definition in sight that will make Pluto a planet without also including about 15 other objects in our solar system. Although Weintraub eventually comes down on this inclusionist side, the overall taste the book left in my mind was: No, Pluto is just a large Kuiper Belt object.

“Pluto earned its status as a planet by accident”, we learn, because the people who happened to find it were really wanting to find one to explain the supposed differences in Uranus’ and Neptune’s predicted and observed orbits by the new planet’s gravitational tug. They saw Pluto, called it a planet and the name stuck.

This book raised more questions for me than it provided answers, which I really enjoyed. For example: Could you measure the parallax of a train that looks like it is moving when you are on the one pulling away? How come I didn’t know that the Moon does not actually orbit the Earth but they both orbit a point very close to the centre of the Earth? Who named Pluto? Can you observe the change in planets from prograde to retrograde motion or is it theoretic? Why were the moons of Mars called Fear (Phobos) and Panic (Deimos)? Answers, anyone?

Weintraub takes the reader on a tour through astronomy’s history and while he is very thorough I was hoping for a style slightly more awe-inspiring, given the suitable topic. Thinking about Pluto’s moon Chiron and its likely fate of a change in orbit, “perhaps directly into the Sun or onto a collision course with Earth or Jupiter or Saturn” – this is the kind of spine-tingling sense of foreboding you can only really get from astronomy and I love it.

“Madame Curie”, Eve Curie

This is the second biography of a scientist I’ve read, this one written by a family member – Marie Curie’s daughter, who, incidentally, died at the age of 102 while I was reading this book. The close relationship between subject and author had all sorts of implications. Most noticeably, this is probably the most thorough and personal book about the double Nobel laureate anyone was ever likely to write.

Eve Curie, born when her mother was 37 and her father was to live only 16 more months, naturally mentions the scientific achievements of Madame Curie, and goes into great detail on her attitude to work, but the physiochemical ins and outs of the discovery of polonium and radium (or any other of Marie Curie’s works) are largely glossed over. Since I am not well versed in physics or mathematics this suited me fine and from the start I was taken captive by the life of the Polish student who adores her family and her country but is unable to pass the opportunity of studies in France.

I became engrossed as in a novel, waiting excitedly for the chapter entitled “Pierre Curie”, where the serious and hard-working heroine meets the love of her life. The love story between her parents is described tenderly by Curie and if not textbook romantic, it is certainly fulfilling and extraordinary.

It is odd and possibly intentional how the biography progresses when Pierre Curie dies in a traffic accident. Up to this point, Marie’s life was recounted chronologically and in minute detail, while afterwards her years blend into each other. Moods and events in the physicist’s life are described in a seemingly arbitrary order and her sorrow of having lost her husband is palpable.

Coincidentally I was reading this book while in Paris and found myself on an accidental secular pilgrimage: depressed at the street corner where Pierre died, enjoying the view in the street where Marie spent the last years of her life, and even unexpectedly found that their bodies had since been moved to the Panthéon, the resting place of the people France is most proud of.

Eve Curie’s arcane writing style (the book was first published in 1937) throughout evokes the admiration for her famous mother, without euphemising her flaws. Madame Curie is portrayed as a highly intelligent and motivated woman with no great natural skills for housework or personal friendships and no time for leisure. She raised her daughters sometimes controversially (the elder, Irène, also won a Nobel prize later, so her methods can’t have been all wrong) and scorned all publicity and anything that would distract her from science. Her religious views changed from Catholic, raised by a pious mother, to the view expressed in the following excerpt from a letter to her cousin.

“Let everybody keep his own faith, so long as it is sincere. [...] I respect sincere religious feelings when I meet them, even if they go with a limited state of mind.”

In fact, the many examples of Marie’s writing, her direct quotes and letters addressed to her, are among the highlights of the book. As a young woman she writes down the beautiful headstrong motto: “First principle: never to let one’s self be beaten down by persons or by events”. At the height of her undesired fame she points out to a journalist how “In science we must be interested in things, not in persons”, and this seems to sum up her character well.

Unusual events from Marie Curie’s life that I had never heard of include her friendship with the royal Belgian couple and her creation of an X-ray lab on wheels servicing military hospitals during the first World War.

Despite this intimate book, Madame Curie remains alien to me, she is unlike anyone I have met in real life. But maybe therein lay the appeal, for me and all those she inspired during her lifetime.

“A Short History of Nearly Everything”, Bill Bryson

When I read this book it changed my life. Then again, reading this book and my life changing may have been co-incidental but when I had finished “A Short History…” I knew that I was

a) completely in awe of science, nature (not the journals) and chance and

b) a full-blown atheist.

Bryson considers each major area of science at a time and walks the reader through all its major achievements and discoveries. It takes a lovely personal spin on things as he gives the big names personalities and stories, and reminds us how the real thinker behind an idea is often not credited.

Being a non-scientist, Bryson manages to take us to great scientific depths without ever becoming too technical, so this book is ideal for anyone with a respect or a curiosity for science or anyone who just needs a little perspective on human life.

The cover promises a story full of “wonder and delight” – true, but given the frequent reminders of various disasters that, statistically, should soon befall the Earth, one might add “panic” to the feelings this book inspires.

But given the amazing string of coincidences that lead to life being here in the first place, we shouldn’t really complain if this lucky streak were to end.

This book has some brilliant quotes, like calling humans “the living universe’s supreme achievement and its worst nightmare simultaneously”.

Bryson is obviously a very good travel writer, but taking a stroll through the universe with him is undoubtedly my best Bryson-reading experience.
