The Age of the Universe - A Torah True Perspective
This is a transcript of a lecture given by Rabbi Aryeh Kaplan z'tl on the question of the age of the universe: Is it around 6000 years old or billions?

Azimuthal Modulational Instability of Vortex Solutions to the Two Dimensional Nonlinear Schrödinger Equation
We study the azimuthal modulational instability (MI) of vortices with different
topological charges, in the focusing two-dimensional nonlinear Schrödinger (NLS) equation.
The method of studying the stability relies on freezing the radial direction in the
Lagrangian functional of the NLS in order to form a quasi-one-dimensional azimuthal
equation of motion, and then applying a stability analysis in Fourier space of the azimuthal
modes. We formulate predictions of growth rates of individual modes and find that vortices
are unstable below a critical azimuthal wave number.
Steady state vortex solutions are found by first using a variational approach to obtain
an asymptotic analytical ansatz, and then using it as an initial condition to a nonlinear equation
numerical optimization routine. The stability analysis predictions are corroborated by direct
numerical simulations of the NLS performed on a polar coordinate finite-difference scheme.
