The River of Time de Igor D. Novikov

Acabo de terminar un libro precioso llamado El elogio de la sombra de Tanizaki (sobre como la sombra y la ausencia de luz y como afectan a la estética japonesa. Además de contener todo un canto de amor al retrete). Y ahora me preparo para leer algo de divulgación: The River of Time, escrito por un ruso que parece ser muy importante en su campo.

Can we change the past?

The surprising answer to this question can be found in the final chapters of this book.

Examining the history of the study of time, from the classical Greeks through to the present day, and presenting in detail the modern state of physical research on the subject, this book is a superb overview of a fascinating subject.

The figures who have helped to shape our views on time are presented as real people, in the context of their own times and struggles: from Socrates’ troubles in Athens, to the experiences of physicists under the former Soviet Union. In addition Novikov details his own experiences with great Russian and Western physicists, such as Sakharov, Zeldovich, Rees and Hawking, and his travels in the West before the fall of the Iron Curtain.

Details of modern theories in fields such as the possibility of time machines, anomalous flows of time (at black or white holes) and the possible source of The River of Time are described with authority and clarity. These are areas in which Novikov is himself a leading researcher.

Accessible to all, the engaging style and wonderful illustrations make this book hugely enjoyable to read.

Esas langostas voladoras

Según la web de telecinco (hace unos minutos), se frena la llegada de langostas a Canarias, a pesar de lo cual los agricultores siguen preocupados. Me sorprende, porque miren:

Porque vamos, si esos son los bichos, yo quiero plagas así todos los días. Saldría a buscar de inmediato recipientes para hervirlos.

Más de cerca:

Yo no sé mucho de biología, pero me atrevo a sugerir que eso es un crustaceo y no un «insecto ortóptero, saltador, de costumbres migratorias, que se reproduce copiosamente, llegando a constituir verdaderas plagas para la agricultura (Pachytylus cinerascens)» (mi diccionario dixit).
