I read to the point it's a sin and this is one of, if not the best book on science and the people involved that I've ever read! I wish there was some way to give it more than 5 stars. It points out, but subtly, the problems with NASA and how the bureaucracy has taken over from the scientists and it also shows how hard it is to "go up against the establishment". How things will finally turn out with this "rock", the real hero in this book, isn't clear since there's still a great deal more we need to learn about Mars as well as about life in general but yet again I can't recommend this book too highly. BUY IT!
I have been fascinated with the Mars meteorite that was the subject of so much scientific controversy. So I was delighted to find this book to help shed some light on it for me.This got off to a somewhat slow start, which was necessary to give the background information on how this meteorite was found, and why it subsequently languished, all but forgotten, in a drawer for many years before someone finally thought to more carefully examine it.But what a rock it turned out to be. It turned into such a big deal and subject of intense interest that President Clinton made an announcement about the mind blowing discovery of what "looked like" life forms from another planet.These apparent life forms came to our planet in the form of microbial fossels, about one hundred times smaller in diameter than a human hair.This book becomes more and more fascinating as you go along. If you have an interest in astronomy and fossels this goes into much detail about the hundreds of scientific tests that were carried out on pieces of this meteorite by scientists all over the world as they tried to figure out what exactly was in this rock and if it was, in fact, biological in nature.As one scientist said after viewing a super-thin slice of this under an electron microscope, if this had come from a rock from earth it would automatically be seen as fossils of microbes. The anatomical parts were indeed present, as were egg shaped objects which couldn't be identifed aside from the abundant carbonite elements, which were clustered around the microbial shapes. There was water and carbon dioxide, as well as carbonites, contained within this fist sized rock.Over three hundred scientists worldwide examined and tested minute pieces of this meteorite, all drawing their own varied conclusions about the meaning of their test results. How does a scientist say with absolute certaintly that what his tests are showing are the result of life? It turns out the answer is not that easy. Yes, the tests do indeed indicate that everything is present in this amazing meteorite for an average scientist to conclude that there was life forms of microbes housed inside. But that doesn't mean with 100% certainty that this is evidence of life from Mars.A scientist has to be very very careful to err on the side of caution about such an important discovery. Nasa eagerly proclaimed that this Mars meteorite shows evidence of past life on Mars, but was forced to back away from that pornouncement by the powers that govern it, for unexplained reasons.I listened to this on my Kindle and couldn't wait to find time each day for the next thrilling chapter in this excellent book. If you have scientific curiosity about what may to date be our best clue about life on Mars, you will love this well written book. It is a detective story with hundreds of detectives piecing together clues about something that may be the beginning of one of the greatest discoveries mankind has ever made.
The story is potentially interesting, but the writing is so bad that it's painful. The author tries to use so many inappropriate analogies, metaphors, similes, adjectives, etc. She strives so hard to be poetic that is she disregards the science - which is what the book is supposed to be about. Also, she includes so many irrelevant details that it hampers the storytelling and drags things out. And she tries to make the event and the discoveries more momentous than it really is. Painful to read, but a story I wanted to know.
I highly recommend this excellent, very honest, well documented and balanced book. Everyone interested in the intelligent design controversy should read this book. It gives an accurate picture of both how science works and scientists as people which is quite in contrast to the public's perception of both. Sawyer documents that scientists not uncommonly behave like children arguing whose father is the strongest or can beat someone else's dad up. The book is about the scientific question of whether life once existed on Mars. The focus of the book is on a meteorite that researchers concluded is from Mars. Inside of the meteorite scientists have found evidence of bacterial life. When one figures in the dollar cost of Mars probes and the enormous time, money and resources spent on researching the Mars rocks, the cost is in the billions. Although much has been learned about many things in science from the research, a common concern is that the money could be much better spent elsewhere. One example is, one researcher has estimated that a billion dollars could defeat tuberculosis. Why spend this much money on Mars probes and on rocks to find evidence of life there? The reason is, if life, any kind on life, is proven to have existed, or to exist, on Mars this will demonstrate that, given the right conditions, life will eventually evolve most anywhere, providing strong support for both naturalism and molecules to man evolution. It will also strike a blow to theism and religion in general. In the end, this 394 page book concluded that there does not seem to be much good scientific evidence that the rock contained evidence of life, nor does there exist evidence of life, past or present, on Mars. On another point, it is commonly believed that J. William Schopf has proven the existence of at least 5 microbial life forms dating back to 3.5 billion years. I have been telling this to my students since he published his conclusions back in 1980. Sawyer documents that this claim is mostly speculation and good arguments exist to dispute this "well known fact." For example, see page 249 to 254 for Dr. Brasier's valid well documented scientific concerns about this claim, and page 254-260 for Schopf's attempt to rehabilitate himself. Sawyer reports that a Nature journal summary wrote that in the end "most judges gave a clear points victory to Brasier" and Schopf "had won few converts to his cause" (page 260). From now on after I explain to my students the "long held fact that humans have 100,000 genes has now been shown to be false" I will explain that the "fact" cited in your textbook that at least 5 microbial life forms dating back 3.5 billion years has been confirmed is also now very doubtful.
Wonderful indepth look at science in the raw...real adventure for a science teacher
Yes, the book is in wonderful condition. Looks new to me
