Abstract
La Astronomía, quizá la ciencia organizada más antigua, presente en todas las culturas, que en este Siglo XXI es fundamentalmente Astrofísica, intenta penetrar en el conocimiento de la naturaleza y evolución del Universo, en su conjunto y en detalle. En tan desmesurada aventura, la clave para avanzar sigue siendo la observación astronómica. Y Canarias ha tenido la suerte de que la atmosfera de sus cumbres posea condiciones excepcionales para la observación astronómica. Por eso los observatorios del Instituto de Astrofísica de Canarias (IAC) reúnen la batería más completa de telescopios. Estos observatorios de Canarias constituyen una reserva astronómica mundial, protegida por ley, donde tienen telescopios e instrumentos más sesenta instituciones de dieciocho países. En el Observatorio del Roque de los Muchachos, además, acaba de entrar en operación el Gran Telescopio Canarias, construido por España. Siendo, con sus 10.4 m. de apertura, el mayor y más avanzado telescopio óptico-infrarrojo del momento. Pronto, esperamos, que a él también venga el Telescopio Europeo Extremadamente Grande (E-ELT) de 42 m., haciendo de en nuestras Islas el centro de gravedad de esta rama de la Ciencia.
La Astrofísica demanda la última tecnología para sus instrumentos en tierra y espacio. Por eso es germen de desarrollo tecnológico e industrial. Lo que supone riqueza económica y social. Sin dejar de ser por ello, como toda ciencia básica, fuente de cultura, al tratar de dar respuestas a las preguntas fundamentales del ser humano, y dotarle de nuevas cosmovisiones.
Abstract
There are many cases in the scientific literature where published results are shown to be "fiascos". Most of them are due to lapses, unconscious mistakes in the analysis or wrong assumptions, but there are other cases where an intentional manipulation/falsification of data was proved. This is one of the multiple misconducts which reflect a lack of ethics in some scientists. Whether prosecution and punishment should be applied to these cases is something discussable.
Abstract
Human beings are born astronomers. Ever since they learned to walk upright they have looked at the sky and wondered. The sky has remained the same but not its meaning. We can distinguish between three phases in the history of humankind’s relationship with its cosmic environment: (i) propitiatory phase; (ii) negotiatory phase; and the current (iii) sky-as-an-object phase. My concern today is to discuss the interplay between astronomy and culture in general in the Indian context. Much of the discussion belongs to the negotiatory phase. More specifically I would discuss how in the formative era, sacred texts influenced astronomy, how these texts themselves were modified under the influence of new scientific developments, and how mythology was upgraded to keep pace with science.
Abstract
Jan Brueghel depicted telescopes in four paintings spanning the period between 1609 and 1621. We have investigated the nature and the origin of these telescopes. An optical "tube" that appears in the painting dated 1608-1612, and probably reproduced also in a painting of the 1621, represents one the earliest documentation of a Dutch spyglass which could even tentatively attributed to Sacharias Janssen or Lipperhey, thus prior to those made by Galileo. Other two instruments made of several draw-tubes which appear in the two paintings of 1617 and 1618 are quite sophisticated for the period and we argue that may represent early examples of Keplerian telescopes.« Newer Older »
