Principles of Religious Liberty

On October 6, 2017, in response to a Presidential order on religious liberty, the U.S. Justice Department issued twenty principles as guidance to all executive departments and agencies stating federal legal protections for religious liberty. For the full text, see here. Below are the principles. Principles of Religious Liberty The freedom of religion is a […]

Centrists and extremists

There are a variety of centrists, as there are a variety of means (e.g., arithmetic, geometric, harmonic, etc.). But all centrists share certain characteristics, which differ markedly from all extremists. Centrists reside in the center, the middle, from a long-term perspective. Unlike moderates, who go with the flow of current politics and culture, centrists resist

Algebraic relativity

Relativity may be derived as an algebraic relation among differentials. Consider motion in the x spatial dimension, with a differential displacement, dx, differential velocity displacement, dv, and arc (elapsed) time t: dx² = (dx/dt)²dt² = dv²dt² =  d(vt)². Let there be a constant, c: dx² = d(vt)² = d(cvt)²/c² = d(ct)² (v/c)² = d(ct)² (1 –

Amateur and independent science

An independent scientist (or gentleman scientist) is someone who pursues scientific research while being independent of a university or government-run research and development body. “Self-funded scientists practiced more commonly from the Renaissance until the late 19th century … before large-scale government and corporate funding was available.” (Wikipedia) Independent scientists are amateurs in the sense that

Measures of motion

This post follows others such as the one here and here. A background document is here. One-dimensional kinematics is like traveling in a vehicle, and on the dashboard are three instruments: (1) a clock, (2) an odometer, and (3) a speedometer. In principle the speedometer reading can be determined from the other instruments, so let’s

Conservatives and liberals

The terms “conservative” and “liberal” are used in a variety of contexts but what is the distinction? They have come down to us through 19th century politics, but that turns out not to help much since many conservatives today would consider themselves as “classical liberals”. One can use alternate terms such as traditionalist and progressive,

Temporo-spatial polar coordinates

This post follows the material on polar coordinates from MIT Open Courseware, here. Instead of the space position vector r, we’ll use the time position vector w, and replace (arc) time with arc length, s. In polar coordinates, the time position of a tempicle A is determined by the value of the radial duration to
