    Einstein’s theory of General Relativity offers a remarkable description of gravity as curved space and time.  Many of the consequences of this theory have been confirmed and some are used daily, such as the gravitational redshift effect on GPS satellite atomic clocks.  In 2015, the first observation of a gravitational wave from two inspiraling black holes occurred using the gravitational wave observatories as part of the worldwide LIGO-VIRGO collaboration.  This discovery won the nobel prize and the observations of these events has continued including a multimessenger event of two colliding neutron stars.

    This study proposes to test and collect data on the effectiveness of commonly used physical security systems in delaying intruders. The purpose of this study is to support the design of better physical security systems for schools. The study will also gather data on parent and teacher perceptions of the quality of security in schools.

  • Matrix Analysis and Operator Theory

    PI Edward Poon

    Matrices and operators are ubiquitous throughout science, engineering, and mathematics; they are the transformations that arise whenever one studies a linear system (or approximates a nonlinear system by a linear one). Examples include rotations and reflections (rigid motions of space), spin operators (quantum mechanics and quantum computing), stress tensors (mechanics), regression and curve fitting (statistics and data analysis), derivatives and linear differential operators (dynamical systems), to name just a few.  By studying various properties, relations, and transformations of matrices and operators one may obtain insight into a wide range of phenomena.

  • Astroparticle Physics

    PI Darrel Smith

    CO-I Brennan Hughey

    In the 1950's and 1960's, high-energy and cosmic-ray physics developed into two different fields of research. However, in the last twenty years they have come together in a most peculiar way. As space physicists explored the sources and mechanisms for producing cosmic rays, they also realized that it was impossible to measure the dynamics of the early universe (i.e., the first 400,000 years).

  • Exotic Propulsion

    PI Darrel Smith

    Exotic propulsion has captured the interest of many Embry-Riddle students. As NASA plans its manned mission to Mars, we come face-to-face with a fundamental dilemma -- a round trip to Mars will take almost three years with traditional chemical rockets!

  • Analyticity and kernel stabilization of unbounded derivations on C*-algebras

    We first show that a derivation studied recently by E. Christensen has a set of analytic elements which is strong operator topology-dense in the algebra of bounded operators on a Hilbert space, which strengthens a result of Christensen. Our second main result shows that this derivation has kernel stabilization, that is, no elements have derivative eventually equal to 0 unless their first derivative is 0. As applications, we (1) show that a family of derivations on C*-algebras studied by Bratteli and Robinson has kernel stabilization, and (2) we provide sufficient conditions for when two operators which satisfy the Heisenberg Commutation Relation must both be unbounded.
