Cosmic balloons.
Cosmic balloons, consisting of relativistic particles trapped inside a spherical domain wall, may be created in the early universe. We calculate the balloon mass M as a function of the radius R and the energy density profile, ρ(r), including the effects of gravity. At the maximum balloon mass 2GM/R ≈ 0.52 for any value of the mass density of the wall. [email protected] Domain walls may fo...
متن کاملSounding Off
Networked communications accord the voice renewed spatial significance. How does the mobile phone influence the use and design of spaces? The conventions for modulating the voice in face-to-face exchanges are well established. But in the case of mobile communications the voice may be raised to abnormal levels. The raised voice overcomes ambient interference, and spatial distance. The voice is a...

متن کاملSounding Objects
virtual environments, and information display applications need dynamic sound models rather than faithful audio reproductions. This implies three levels of research: auditory perception, physicsbased sound modeling, and expressive parametric control. Parallel progress along these three lines leads to effective auditory displays that can complement or substitute visual displays. W hen designing ...
متن کاملMagma balloons or bombs?
To the Editor — Detailed analysis of volcanic materials1 allows the study of eruptions that have not been witnessed directly. Rotella et al.2 undertake the challenge of interpreting submarine volcaniclastic deposits around Macauley Volcano, part of the Kermadec Arc in the southwest Pacific Ocean. They propose a ‘Tangaroan’ eruption style, based on the textural characteristics of dredged pumice ...
