دانلود کتاب The Simple Science of Flight, Revised and Expanded Edition: From Insects to Jumbo Jets

This is a very interesting book and I highly recommend it. It explains the science of flight primarily about birds and jet airliners. Don't think that the science of the flight of birds and of jet airliners is related? Yes they are, and this book explains why. Please see the reviews of his earlier book which this is an expansion of. I pretty much agree with those reviews which certainly apply to this expanded book.

There is a certain minimum degree of knowledge about science and mathematics (algebra) that is helpful but not necessary to enjoy this book.

There is perhaps only one negative comment I would make on the book and that is that it could use the help of a good editor. I suspect that the author, a professor of meteorology, probably said - the book is fine, it doesn't need an editor and if people have problems with it, that's their problem not mine. If the book were better edited, it would probably make it more appealing to readers who might be turned off on it after a few pages. My suggestion is - wade through those first few pages and you will be rewarded.

One other comment. His discussion about the units used in the equations is correct but somewhat confusing. He uses the newton as a unit of force, which a causal reader may not be familiar with. The confusion arises from not explaining the common (non-scientific) use of grams, kilograms, etc as units of weight. In science, grams, kilograms etc are units of mass not weight. Mass times gravity (the constant g) is weight (weight is a force, and measured in newtons). This relationship is not clearly explained.
