La historia del hombre que llevó la física a sus límites... y a los suyos propios. Una vida de descubrimiento, genialidad y aislamiento.Roger Penrose, uno de los grandes genios que nos ha dado el siglo XX, revoluciono nuestra comprension del espacio, el tiempo y los agujeros negros. Premio Nobel de Fisica, colaborador de Stephen Hawking y creador de algunas de las teorias mas audaces y controvertidas sobre el universo, Penrose ha sido una figura clave en la ciencia contemporanea. Sin embargo, su genialidad vino acompañada de una gran dificultad para conectar con otras personas.El hombre imposible es la primera biografia completa y profundamente humana de Penrose. A lo largo de estas paginas, el periodista cientifico Patchen Barss narra, con precision y empatia, los grandes hitos cientificos y las multiples paradojas personales de un hombre que vivio a caballo entre la matematica trascendente y el desconcierto emocional. Desde su infancia marcada por la frialdad paterna hasta sus ideas visionarias sobre el universo y la conciencia, este retrato revela el precio a menudo muy alto de una vida dedicada por entero al pensamiento.

Santiago Ramón y Cajal, premio Nobel de Medicina y el mayor genio científico español de todos los tiempos, es retratado por fin en toda su complejidad en esta emocionante biografía.Cajal, padre de la neurociencia, es, junto a Darwin y Pasteur, uno de los cientificos mas brillantes en el ambito de la biologia. Sus descubrimientos han transformado nuestra comprension del cerebro de manera similar a como lo hicieron los de Copernico, Galileo y Newton con el Universo. Recibio el Premio Nobel en 1906 por sus investigaciones sobre la estructura de las neuronas, esas misteriosas mariposas del alma, cuyo batir de alas quien sabe si esclarecera algun dia el secreto de la vida mental.La apasionante y bien escrita biografia de Ehrlich, documentada con el rigor de la escuela anglosajona y rebosante de admiracion, relata la epopeya de un niño nacido en las montañas del Alto Aragon que alcanza, sin contar con el apoyo de ninguna tradicion cientifica, el mayor reconocimiento mundial. En una España convulsa y llena de claroscuros, Cajal sobresale como un autodidacta incansable que solo consigue la ayuda de las instituciones tras ser considerado una eminencia en el extranjero. Ehrlich resalta su tenacidad, su pensamiento visionario, sus extraordinarias habilidades, entre las que destaca la de dibujante, y las disputas con sus rivales, siendo el mas notorio Camillo Golgi, con el que compartio el Nobel. La sencillez con la que explica sus increibles hallazgos y los de aquellos que le precedieron permite que cualquier lector pueda comprenderlos y valorarlos.El libro cuenta con fotografias en blanco y negro para ilustrar el texto y 16 de los dibujos mas emblematicos de Cajal a color.HAN DICHO:Benjamin Ehrlich ha escrito una biografia apasionante de Santiago Ramon y Cajal. La ha titulado El cerebro en busca de si mismo. Ehrlich ha montado la vida de Cajal como un pequeño gran puzle de piezas cortas. Hasta las cuestiones mas tecnicas y cientificas parecen sencillas y en su relato la doma de los seres infinitamente pequeños forma parte a menudo de un relato policiaco. Y de mano maestra esta contado el ambiente de aquella España provinciana de siglo XIX en el que un ser excepcional, llamado a ser un medico de pueblo, como su padre y su hermano, alcanza las cotas mas altas de la ciencia de su tiempo. Andres Trapiello, La Lectura, 27-06-2025El cerebro en busca de si mismo: la biografia definitiva de Santiago Ramon y Cajal. Pocos autores se atreven a contar la ciencia como una gran narracion humana, llena de pasiones, desafios y derrotas. Benjamin Ehrlich ha logrado con El cerebro en busca de si mismo un raro equilibrio entre el rigor biografico y la vibracion literaria. El cerebro en busca de si mismo no es solo la mejor biografia de Ramon y Cajal publicada hasta la fecha; es un testimonio de como un solo individuo, armado de conviccion y asombro, puede cambiar el rumbo de la historia intelectual de su tiempo. Un libro que se lee con gratitud y que, con seguridad, inspirara a nuevas generaciones de lectores y cientificos. Marcelo Brito, Fanfan, 27-06-2025

Nueva edición por el 100 aniversario del nacimiento del Dr. Favaloro. Uno de los médicos más reconocidos del país rememora sus experiencias como médico en un pueblo del oeste pampeano y reflexiona sobre las condiciones en las que se ejerce su profesion en la Argentina.Entre comienzos de la decada del 50 y 1962, Rene Favaloro se desempeño como medico rural en el pueblo pampeano de Jacinto Arauz. Estos doce años fueron los que lo definieron, tanto en su vida profesional como en la personal. El mismo doctor que se volvera una eminencia años despues en Cleveland, trabajando con los profesionales mas destacados de la medicina internacional, inicio su carrera en el interior de la Argentina, y fue esa labor lo que mas marco su vocacion. En 1980 publico esta obra, su primer libro autobiografico. En el reflexiono acerca de su propia experiencia y del ejercicio de la medicina en algunas zonas postergadas del pais, a la vez que advirtio sobre el devenir de la practica publica de la salud y cierta decadencia en la formacion de nuevos medicos. Recuerdos de un medico rural tuvo un gran recibimiento. "Mi objetivo -decia en el prologo a la segunda edicion, que escribio emocionado por las cartas que le habian enviado cole - gas y maestros rurales que se sintieron representados en sus escritos- no es presentar la simple descripcion de hechos anecdoticos sino, a traves de ellos, mostrar las condiciones socioeconomicas del interior". Y se preguntaba: "¿Tendremos capacidad de reaccionar? ¿Seremos capaces de realizar la verdadera reconstruccion?".
