Capillarity and Wetting Phenomena, like every text and paper bearing the name of de Gennes is intuitive, insightful, elegant, beautiful and extremely useful text. The names de Gennes, Brochard and David Quere are well known to the researchers in this area, and this book basically brings together their deep insight about a host of different phenomena in very simple words and equations. The described physics of wetting, surface tension, droplet spreading, instabilities, bubbles, etc. is developed in a style where qualitative arguments, dimensional arguments and experimental observations are used to describe a variety of complex phenomena. The apparent lack of mathematical rigor is a blessing to everyone interested in developing a taste and temperament for this extremely important field. While one can find several related texts in the field, none other is written in this delightfully insightful way. This is one of the rare gems that everyone from a high school student to most advanced researcher in the field can read, enjoy, learn from and be delighted to possess.

I had the original in French, and got the English version trying to understand it faster. I was very dissapointed when I found phrases as:

"The puddle is the seat of a certain internal pressure p_2>0"

A puddle being a seat? I just don't catch the metaphore. The original in french says,

"Il existe une certaine pression interne p_2>0"

Which is, as you can googletranslate, "There is some internal pressure p_2> 0".

This is a great book for anyone interested in capillarity and wetting phenomena. What I like about it is that it gives the reader a grasp of how things work and it goes through a lot of practical examples. The equations are voluntarily simplified (constants often omitted) to only leave the important variables and reveal the "mechanics of how things work". However, although the equations look simple, they do capture the essence of the problem and they are always perfectly sound. This is an approach that de Gennes uses a lot and which I believe makes things easier to understand. Moreover, the 3 authors of the book are, like the previous reviewer said, very well known and respected scientist in their field, which adds to the scientific soundness of their approach. In summary, I highly recommend this book to anyone interested in the physics of wetting.
