...range of effects as he could with different brush strokes on oil, tempera or water color. Like the painter, the photographer produces these results with varied techniques and the Fogg exhibit investigates them. Here we have a chance to see and compare the daguerreotype and the calotype, photogravure and gum-biochromate; platinum, palladium and cyanotype. I don't know the chemistry or history behind all these processes, but in this exhibit ignorance is not a hindrance to understanding. The photographs--with their similarities and contrasts--make all the necessary explanations of style...
...Merritt portrays Nathan with an appropriate and consistent accent, and possesses a good sense of timing. There are several fine comic moments between Nathan and his fiancee of fourteen years, Miss Adelaide (Joann Beckson). Miss Beckson is outstanding, bringing to the role all of the necessary chintziness and gum-cracking, charm, coupled with a comic flair and a powerful voice. Her rendition of "Adelaide's Lament" is delightful, as is her duet with Nathan...
...only known evidence of earlier supernovas in the Milky Way are the pulsars they left behind. One of the closest to be detected is in the Gum nebula, which is in the constellation Vela and only 1,500 light years away. Thus, when the star that formed Gum exploded-some 10,000 to 20,000 years ago (an estimate derived from the current signal rate of the pulsar)-it probably flared up briefly in the sky as bright as a quarter-moon. It also may have showered the earth with enough dangerous radiation to have produced significant mutations in terrestrial...
...great event-markings that could be archaeologically dated to determine more precisely when the Vela supernova occurred-NASA Astronomers John C. Brandt, Stephen P. Maran and Theodore Stecher last year issued an appeal. They asked archaeologists to be on the lookout, especially in the Southern hemisphere-where the Gum nebula can be best observed-for any unidentified ancient symbols that might have been painted or carved to represent the supernova...
Returning to the site of the markings in Bolivia, Michanowsky noted that the region of the sky in which the Gum nebula lies does not look remarkable to the naked eye. Nonetheless, it has long been called Lakha Manta (The Gateway to Hell) by the Indians, for reasons they are unable to explain. More tantalizing still, Michanowsky found that among some lowland tribes this humdrum part of the sky is known as the Region of the Chase of the Celestial Ostrich, a bird revered in Indian mythology. According to Indian lore, the ostrich was driven across...
