Imaginative Cosmology
We review a few off-the-beaten-track ideas in cosmology. They solve a variety of fundamental problems; also they are fun. We

L^2 Cohomology on coverings of a compact Kähler manifold
Andreotti-Vesentini, Ohsawa, Gromov, Kollár, among others, have observed that Hodge theory could be extended to (non compact) Kähler complete manifolds,

Linear and non-linear dielectric spectroscopy on ammonium doped Rochelle salt
In this work we present a thorough investigation of the mixed system of Rochelle salt doped with ammonium, with 0<=x<=1

Look Back Time, the Age of the Universe, and the Case for a Positive Cosmological Constant
We present explicit expressions for the calculation of cosmological look back time, for zero cosmological constant and arbitrary density parameter

Magnetic Phase Diagram of Weakly Pinned Type-II Superconductors
The phenomenon of superconductivity was discovered in 1911, however, the methodology to classify and distinguish type-II superconductivity was established only

New Perspectives on Type Ic Supernovae
The Type Ic supernovae are probably "nearly-nude" core collapse events. They are thus of special interest in terms of their
