TB for text, but very bad for the presentation.

Text very interesting but extremely painful to read: too little writing with letters 1.5 mm high while a classical writing for letters of 2 mm high. Worse, many texts have letters of 1 mm height (ex. P 37 bottom right, or p 124-125 °, or p 185) This is even worse when the writing is in italics ( ex. p 201).
Moreover, the texts are too tight. It would be better to provide a more grand.pour size make you want to read this book.
