The physics of flotation in Manta birostriswas analysed and the swimming of this species was compared with the flight cycle of the common pigeon Columba livia, in order to find similarities and differences in their locomotion patterns and the laws of physics driving them. It was showed that the cycleof M. birostris has three of the main four stages of pigeon’s flying cycle. A “Parachute effect” was also demonstrated, which give an advantage on ray´s locomotion. Moreover, it was described how torque concept is applied to turn of this species.

In this paper, the plesiosaur records for Peru are reviewed and material referring to plesiosauria deposited in the Natural History Museum of the UNMSM is described. The plesiosaur records of Peru are extended since the Valanginian-Hauterivian (Lower Cretaceous) to the Maastrictian (Upper Cretaceous). In relation to the taxonomic position, the material is attributable to Plesiosauria indet., Elasmosauridae indet., while the new material studied is possibly Pliosauroidea indet., and will be the first records of this group in Peru. Likewise, the Morro Solar plesiosaur is the only one from the Lower Cretaceous and the oldest in Peru.

Se realiza un recuento de los registros de plesiosaurios de Perú y se describe material referido a plesiosauria depositado en el Museo de Historia Natural de la UNMSM.El registro de plesiosaurios de Perú se extiende entre el Valanginiano-Hauteriviano (Cretácico Inferior) hasta el Maastrictiano (Cretácico Superior). En relación con la posición taxonómica, el material es referible a Plesiosauria indet., Elasmosauridae indet., mientras que el nuevo material estudiado es posiblemente referible a Pliosauroidea indet., constituyendo el primer registro de este grupo en el Perú. Asimismo, el plesiosaurio del Morro Solar es el único del Cretácico Inferior y el más antiguo de Perú.

Science-fiction film Interstellar (2014) explores the possibilities offered by Einstein’s general relativity theory through wormholes, black holes and time dilation with great realism. This work studies all the sequences related to physics, especially the astronauts’ journey through a blackhole. Then, considering modern physics, the plausibility of the physical phenomena presented in the film is analyzed. As the central axis of the study, physics and cinematographic art are intertwined through the film image. It is also demonstrated that the last scenes move away from physical concepts, but as symbolic language they approach Borges’s The Aleph, with which a parallel is drawn. Science and art, realism and fiction are characteristics related to the film that are developed in the present work.

Las aves fósiles de la familia Pelagornithidae fueron grandes aves marinas planeadoras que habitaron desde el Paleoceno tardío hasta el Plioceno. En este trabajo se estudia la capacidad de vuelo de una especie de esa familia, Pelagornis chilensis (MNHN SGO.PV 1061). Utilizando la fórmula de sustentación y fórmulas alométricas, se demostró que diferentes tipos de velocidades del ave fósil son significativamente mayores a las mismas de Thalassarche chrysostoma, el albatros de cabeza gris, el ave marina actual que más se asemeja morfológicamente al ave extinta. Además, en coherencia con los resultados anteriores, se determinó que la potencia parásita, la potencia inducida, la fuerza muscular y el número de Reynolds de P. chilensis son significativamente mayores que las mismas variables de T. chrysostoma. El método fue utilizado en el albatros Diomedea exulans, para comprobar ...
