Rhubarb: the wondrous drug
CLIFFORD M. FOUST, Rhubarb: the wondrous drug, Princeton University Press, 1992, pp. xxii, 371, illus., £27.50 (0-691-08747-4) Children in Russia during the 1960s were fully aware of the existence of rhubarb which, together with castor oil, was one of the staple home medicines. Attitudes varied according to the method of administration. The lucky ones consumed it as compotes and kissels, others...
متن کاملMacho: Programming with Man Pages
Despite years of work on programming languages, programming is still slow and error-prone. In this paper we describe Macho, a system which combines a natural language parser, a database of code, and an automated debugger to write simple programs from natural language and examples of their correct execution. Adding examples to natural language makes it easier for Macho to actually generate a cor...
متن کاملA New Macho Search Strategy
I propose a radical revision in the search strategy for Massive Compact Objects (Machos) toward the Galactic bulge: monitor the entire 300 square deg of the bulge and tune the search primarily to microlensing events of bright M V < 2 stars. By employing a small second telescope to follow up the events detected with low dimensionless impact parameter < 0:2, one could measure the proper motion of...
متن کاملGravitational Microlensing Results from Macho
The MACHO project is searching for dark matter in the form of massive compact halo objects (Machos), by monitoring the brightness of millions of stars in the Magellanic Clouds to search for gravitational microlensing events. Analysis of our first 2.3 years of data for 8.5 million stars in the LMC yields 8 candidate microlensing events, well in excess of the ≈ 1 event expected from lensing by kn...
متن کاملThe Meaning of Eros/macho
Most of the mass density in the Universe—and in the halo of our own galaxy—exists in the form of dark matter. Overall, the contribution of luminous matter (in stars) to the mass density of the Universe is less than 1%; primordial nucleosynthesis indicates that baryons contribute between 1% and 10% of the critical density (0.01h <∼ ΩB <∼ 0.02h; h = the Hubble constant in units of 100 km sMpc); a...
