Gravitational Waves in G4v

Gravitational coupling of the propagation four-vectors of matter wave functions is formulated in flat space-time. Coupling at the momentum level rather than at the "force-law" level greatly simplifies many calculations. This locally Lorentz-invariant approach (G4v) treats electromagnetic and gravitational coupling on an equal footing. Classical mechanics emerges from the incoherent aggregation of matter wave functions. The theory reproduces, to first order beyond Newton, the standard GR results for Gravity-Probe B, deflection of light by massive bodies, precession of orbits, gravitational red shift, and total gravitational-wave energy radiated by a circular binary system. Its predictions of total radiated energy from highly eccentric Kepler systems are slightly larger than those of similar GR treatments. G4v predictions differ markedly from those of GR for the gravitational-wave radiation patterns from rotating massive systems, and for the LIGO antenna pattern. The predicted antenna patterns have been shown to be highly distinguishable in the case of continuous gravitational-wave sources, and should therefore be testable as data from Advanced LIGO becomes available over the next few years.Comment: 37 pages, 14 figure

You\u27re Asleep

I think On automatic pilot In a commuter plane. Flying at night is the most peaceful thing. These lights are our own Tivoli, A cathedral of sky. Going so deep While floating as if through glass As it forms, is to apprehend How significant smallness can be, Meaning us in this vast cavern, Meaning those spires, Those good window faces—Look—down there in the dark.https://digitalcommons.butler.edu/onearth/1029/thumbnail.jp

Maintenance Required: Charter Schooling in Michigan

Michigan's charter sector has tremendous potential, but achieving that potential requires significant improvements

The Truth About Boys and Girls

On many measures American boys are achieving more than ever, but girls have improved their performance even faster. A careful look at the evidence shows the boy crisis hype is overblown and benefits neither boys nor girls

Million Dollar Babies: Why Infants Can't be Hardwired for Success

Conventional wisdom that the ages from zero to three are the most important for children's development is based on misinterpretations and misapplications of brain research. The result: negative consequences for parents and public policy

Information Underload: Florida's Flawed Special-Ed Voucher Program

Despite its growing popularity, and the attention paid both by state and national education reformers, Florida's McKay voucher program has yet to prove that it works as either an adequate school-choice or special-education reform measure

Collective electrodynamics I

Standard results of electromagnetic theory are derived from the direct interaction of macroscopic quantum systems; the only assumptions used are the Einstein-deBroglie relations, the discrete nature of charge, the Green's function for the vector potential, and the continuity of the wave function. No reference is needed to Maxwell's equations or to traditional quantum formalism. Correspondence limits based on classical mechanics are shown to be inappropriate

How Legislation and Litigation Shape School Choice

Since its appearance on the educational landscape, school choice has engendered considerable controversy. Those controversies are captured in two forms of "law" -- legislation and litigation. Government legislation at all levels codifies the results of political struggles around school choice and defines choices available to parents. Those unhappy with the results have brought litigation to determine whether the policies are consistent with constitutional provisions and other existing laws. This policy brief examines the relationships between various forms of school choice and the legal authority that both binds and bounds them. As the discussion will show, both the development of and legal challenges to school choice in its various forms can be traced to a tension between the legal principle that parents should be able to direct the upbringing of their children and the legal principle of parens patriae (the government is the ultimate guardian), which forms the foundation for compulsory education in the United States. As such, school choice legislation and litigation go to the very heart of public education and the societal values it reflect
