It's not the most alluring of titles, I admit, and even though most people have heard of Galileo and many know enough of his achievements to admire him, I suspect few people would consider reading a book by him. However, I urge you very strongly to buy this book and at least give it a try. It's a wonderful work, full of fascinating and brilliant insights and Stillman Drake's superlative translation makes it extremely readable. It gives a fascinating insight into what Galileo *really* did to annoy the Inquisition and shows his often brilliantly witty and occasionally dangerously sarcastic style. Even to dip into, this book is a monumental pleasure.
Try this, the first few lines of the Introduction - To The Discerning Reader:
"Several years ago there was published in Rome a salutary edict which, in order to obviate the dangerous tendencies of our present age, imposed a seasonable silence upon the Pythagorean opinion that the Earth moves. There were those who impudently asserted that this decree had its origin not in judicious inquiry, but in passion none too well informed. Complaints were to be heard that advisers who were totally unskilled in astronomical observations ought not to clip the wings of reflective intellects by means of rash prohibitions. Upon hearing such carping insolence, my zeal could not be contained..."
I first read that while studying History of Science over thirty years ago, laughed out loud, and read the rest of the book with immense pleasure. It is written in the form of dialogues presided over by Sagredo ("wise man") and conducted between Salviati (really Galileo himself) and the person representing the Church's orthodoxy, whom Galileo christened Simplicio. Tactful, he wasn't, but he was a brilliant physicist and a brilliant author, filling the book with witty and amazingly ingenious arguments resulting in poor Simplicio being confounded at every turn.
I cannot say strongly enough what a pleasure this book is. It really isn't just a tome which will sit on your shelf looking impressive, or which you ought to plough through because it will Do You Good. It's wonderfully enjoyable and hugely rewarding, and I recommend it very highly indeed.
