Lecture on Quarkyonic Effective Field Theory

I review the essential features of Quarkyonic Matter. I argue how such features can be included in a field theoretical description. This field theory has nucleons and quarks because close to the Fermi surface, the degrees of freedom of Quarkyonic Matter are nucleons and inside the Fermi sea, they are quarks. Ghost nucleon fields are needed to avoid over-counting degrees of freedom, and to allow the physical nucleon degrees of freedom not to extend within the quark Fermi sea.

Introduction to Nuclear Propulsion: Lecture 15 - Nuclear Test Operations

The test operation of nuclear power plants, specifically nuclear rockets, bears some interesting similarities to the operation of chemical rocket tests as well as, of course, many differences. A significant feature common to both nuclear and chemical rocket tests is that all the fuel for the entire operation is loaded at the start of the test. As a direct consequence of this fact, the operation of nuclear power plants must be surrounded with adequate safety precautions, as is indeed the case in the operation of chemical rockets, A second direct consequence is that in both types of testing a very thorough and complete checkout is made before starting the test.

Lectures in Applied Mathematics. Volume 5 - Space Mathematics, Part 1

The present Proceedings should acquaint the reader with the current state of research on the behavior of nonpropulsive space vehicles, indicate the more pressing unsolved problems, and furnish examples of mathematical techniques which are currently useful. It is hoped that the reader will be stimulated to make contributions of his own, either in the way of developing better mathematical techniques, or finding more ingenious uses of existing ones.
