This short book of poetry is like a chest that opens up full of mystery...it has a complex symbolism, since its author, Carlos Navarrete Miró, was a professor of Philosophy and had a deep and extensive knowledge of the subject. On the one hand, in this strange setting, there are Harlequin and Columbine, eternal characters of Italian Comedy. It is hopeless love, being mocked to the core, but still insisting on the commitment... Death appears, when the mocked lover knows that this fate is better than falling out of love. A biting and ferocious parallelism is established between the mocked lover and the prisoner who is going to be executed and torn apart by the Holy Inquisition... The irony of seeing oneself in the pillory but accepting one's fate. Finally...the sleeper...who prefers to continue dreaming, not to be awakened from his lie...even knowing that she will abandon him. Life as a dream, and as a cruel game, that leads us to fatality. It's certainly autobiographical. "We wake up from the dream we are in, when deadly wounded, we realise that love is no more...we wake up when we see, that our mask falls off, and all is comedy, drama and fake. Life is just a game of chance. This work is a reflection, as a mirror, of dreams come true" María Rita Navarrete Navarro, Carlos Navarrete Miró's daughter and editor of this book.

Quantum information is an emerging field which has attracted a lot of attention in the last couple of decades. It is a broad subject which extends from the most applied questions (e.g. how to build quantum computers or secure cryptographic systems) to the most theoretical problems concerning the formalism and interpretation of quantum mechanics, its complexity, and its potential to go beyond classical physics. This book is an introduction to quantum information with special emphasis on continuous-variable systems (such as light) which can be described as collections of harmonic oscillators. It covers a selection of basic concepts, focusing on their physical meaning and mathematical treatment. It starts from the very first principles of quantum mechanics, and builds up the concepts and techniques following a logical progression. This is an excellent reference for students with a full semester of standard quantum mechanics and researchers in closely related fields.

This edited volume presents twenty papers from a symposium held at the 40th International Congress of Americanists in Rome in September of 1972, focusing on the communication routes then known for Mesoamerica, as well as aspects of environment, culture, and history that had an impact on interregional interactions.
