Of all the French epigrammatic writers, La Rochefoucauld (1613-1680) is at once the most widely known and the most distinguished. Voltaire said: "One of the works that most largely contributed to form the taste of the French] nation, and to diffuse a spirit of justice and precision, is the collection of maxims by Fran ois, duc de La Rochefoucauld; though there is scarcely more than one truth running through the book-that 'self-love is the motive of everything'-yet, this thought is presented under so many varied aspects that it is nearly always striking." And Lord Chesterfield, in his letters to his son: "Till you come to know mankind by your own experience, I know no thing nor no man that can in the meantime bring you so well acquainted with them as La Rochefoucauld: his little book of Maxims, which I would advise you to look into, for some moments at least, every day of your life, is, I fear, too like and too exact a picture of human nature. I own it seems to degrade it, but yet my experience does not convince me that it degrades it unjustly." The Maxims were first published in 1665, under the title "Reflections or sentences and moral maxims"; and the edition of 1678, the fifth, from which the text has been used for the present translation, was the last revised by the author and published in his lifetime (with maxims numbered 1 to 504). Maxims which appeared in previous editions and were suppressed by La Rochefoucauld can be found in the second part, entitled "Maxims withdrawn by the author", here numbered 505 to 583. The French original of this bilingual edition was reviewed by Philippe Renaud. The English translation, originally by John William Willis-Bund and James Hain Friswell, has been thoroughly revised by Rebecca Hazell and Philippe Renaud.

Optical Microscanners and Microspectrometers using Thermal Bimorph Actuators shows how to design and fabricate optical microsystems using innovative technologies and and original architectures. A barcode scanner, laser projection mirror and a microspectrometer are explained in detail, starting from the system conception, discussing simulations, choice of cleanroom technologies, design, fabrication, device test, packaging all the way to the system assembly. An advanced microscanning device capable of one- and two-dimensional scanning can be integrated in a compact barcode scanning system composed of a laser diode and adapted optics. The original design of the microscanner combines efficiently the miniaturized thermal mechanical actuator and the reflecting mirror, providing a one-dimensional scanning or an unique combination of two movements, depending on the geometry. The simplicity of the device makes it a competitive component. The authors rethink the design of a miniaturized optical device and find a compact solution for a microspectrometer, based on a tunable filter and a single pixel detector. A porous silicon technology combines efficiently the optical filter function with a thermal mechanical actuator on chip. The methodology for design and process calibration are discussed in detail. The device is the core component of an infrared gas spectrometer.
