Other sciences … the stars look down
Although most of the journals professing to cover all sciences concentrate their attention on biology, a few still have a fair number of papers in other sciences. Most of the readers of this column probably don't have time to look at these, but I read them, and especially the ones I don't understand too well, in the hope that their very strangeness might shake up my mind to think of something n...
متن کاملWhat other sciences look like 1 Josep
In order to have references for discussing mathematical menus in political science, I review the most common types of mathematical formulae used in physics and chemistry, as well as some mathematical advances in economics. Several issues appear relevant: variables should be well defined and measurable; the relationships between variables may be non-linear; the direction of causality should be c...
متن کاملMigraine: A look down the nose.
BACKGROUND Studies have suggested that contact between opposing mucosal surfaces in the nasal wall and cavity can be a target of the surgical treatment of migraines. Unfortunately, not enough is known about the role of nasal pathology in the pathogenesis of this condition. The co-existence of further rhinological disorders can be an impediment to defining the cause and effect of anatomical vari...
متن کاملOn the spin-down of Be stars
The spin-down of Be stars due to angular momentum transport from star to disc has been considered. This has been prompted by empirical studies of observed optical and IR line profile studies indicating that the disc is rotating in a Keplerian fashion. It is found that substantial spin-down may occur, especially for late B stars throughout their main-sequence lives for the “strongest” discs (mos...
متن کاملA fresh look into pulsating PG1159 stars
To improve the understanding of the pulsational instabilities of some of the PG1159-type pre-white dwarfs we performed detailed stability analyses on helium star evolutionary models. With the canonical chemical compositions, pulsational instabilities were encountered for all stellar masses considered (0.57, 0.63, 0.7 M⊙). The blue boundary agrees satisfactorily with observations. The red edge, ...
