Cosmic Map of Ultrahigh-Energy Particles Points to Long-Hidden Treasures

By NATALIE WOLCHOVER

Ultrahigh-energy cosmic rays twist and turn on their way to Earth, which has made it nearly impossible to identify the colossal monsters that create them.

Hands On

Patricia S. Churchland

During my first neuroanatomy lecture, the patient presented to us was a former dean of the medical school who had suffered a small brainstem stroke. As he started to identify the stroke location, the former dean suddenly began to sob piteously. Deeply concerned, we waited in utter stillness a long minute until, abruptly, his sobbing stopped. Unbothered by the interlude, he calmly went on to explain that the episode was caused by the stroke—damage to a tiny region of the brainstem which released reflexive crying when triggered by high levels of adrenalin. Conscious control was futile. A not uncommon sequel of a brainstem stroke, the condition is known as pseudobulbar affect. Adding to our bewilderment, he commented, almost as an aside, that throughout the crying episode he had felt no sadness whatever, though he did admit to finding pseudobulbar affect a nuisance. This was the first result in my new neurophilosophical world: The disconnect between despondent behavior and despondent emotions was the sort of event that many philosophers, trusting entirely in their own imagination, said was inconceivable and could not happen. But it did happen, right before our wondering eyes. This was the first of a host of “philosophically impossible” revelations from brain-damaged patients.

PATRICIA S. CHURCHLAND is professor emeritus of philosophy at the University of California, San Diego, and adjunct professor at the Salk Institute. Her research has centered on the interface between neuroscience and philosophy, with a current focus on the association of morality and the social brain. She is the author of Conscience: The Origins of Moral Intuition

Há tempos que os físicos não conseguem decifrar o mistério do que aconteceu nos momentos em que uma pequena semente explodiu como o universo. Agora, um cientista acha que sabe por que eles não poderão chegar a uma descrição física deste fenômeno chamado inflação: o universo não permite.

Especificamente, o cientista descreve uma nova conjectura em relação ao universo jovem, “o observador deve ser protegido” de observar diretamente as menores estruturas do cosmos.

Em outras palavras, por definição, os físicos talvez nunca possam construir um modelo de inflação usando as ferramentas usuais, terão que descobrir uma nova maneira./../
No momento, a TCC não está provado, é apenas uma conjectura. Ela se alinha com outras idéias da Teoria das Cordas, mas a teoria das cordas também não é comprovada (na verdade, a teoria ainda não está completa e nem sequer é capaz de fazer previsões). Mas ainda assim, ideias como esta são úteis, porque os físicos fundamentalmente não entendem a inflação, e qualquer coisa que possa ajudar a aguçar esse pensamento é bem-vinda.

#De: Prof. Luiz Eduardo Robinson Achutti (nosso filho)

Entrevista para Jornalista Cubana Maribel Acosta Damas

El desgarramiento de Achutti, fotógrafo viajero de las muchas pieles

Por Maribel Acosta Damas(*) / Colaboración Especial para Resumen Latinoamericano Cuba. 

 / Fotos: Cortesía del entrevistado.

Luiz Eduardo Robinson Achutti es hijo de una generación de intelectuales y artistas brasileños que apostó a la utopía de un mundo mejor. Es Profesor titular del Departamento de Artes Visuales del Instituto de Artes de la Universidad Federal de Río Grande del Sur (UFRGS. En su recorrido por la fotografía de prensa primero y luego por la fotoetnografía, fue incorporando pieles al recorrer su país y muchos otros. La mirada antropológica pasó a ser parte de una obra que tiene anclada su raíz en la vida humana. Medio siglo es mucho tempo para mirar y narrar. Ahí ha estado Achutti. Contando. Visitó Cuba por primera vez en 1986 y se metió en la piel de la isla, sin divagaciones, dejándose llevar entre la gente en un camino preciso y extraordinario. Igual su lente relató los viajes por los países del antiguo Campo Socialista./.../
