Marriage is the coupling of two adults; that is, marriage is a relationship of monogamous copulation. That is why marriage is the union of a man and a woman for life. Two men or two women cannot copulate together. More than two adults cannot be monogamous. A marriage begins when it is consummated, which means […]
Although I’m a centrist, not a conservative, I desire to see the political factions balanced in order to have a balanced politics. But for some time the political left has had excessive influence: they dominate the media (both mass and elite), education, the arts and sciences, professional associations, NGOs, the judicial branch, and in many
I recently wrote about spatial rest and time here. This post is about the opposite: immediate motion, arriving at a destination instantly. Immediate motion means an infinite speed. An infinite speed results in an immediate change of place: something moves from one location to another in an instant. It’s here and there at the same
Previous posts on political centrism are here, here, and here. This post further develops what centrism is. There are three principles of what centrism is: (1) Centrism seeks balance in all aspects of the state and its relationship with individuals, society, and other states. (2) Centrism is non-ideological because ideologies are imbalanced: what distinguishes one
Science has no stories. Stories have characters, plots, and narratives. Science has data, hypotheses, postulates, and theories. Science and stories are different. They should be kept separate. Stories can refer to science or be about scientists, but that is not part of science. Science can refer to stories or collect data from stories, but that
Two transformations of inertial reference frames are well-known: the Galilean and the Lorentz transformations. There is a third transformation as well, which will be called the dual Galilean transformation. Below is a derivation of all three transformations, closely following the paper Getting the Lorentz transformations without requiring an invariant speed by Andrea Pelissetto and Massimo
Watches didn’t always exist. Neither did clocks that were transportable or manufactured in large quantities. I mention this because one way to determine the simultaneity of events is to have synchronized clocks transported to multiple locations – even an endless number of locations in theory. How can an observer determine the simultaneous events from their
Rates of motion are almost always expressed as a ratio with respect to time (duration space). For example, the average speed of a body is the travel distance of the body divided by the travel time. This makes the independent variable time and distance the dependent variable. However, there is no physical dependency of motion
Rest means no motion, or at least no motion detected by an observer. We know what rest for space means: staying in the same place. That is, rest means no change of position, no travel distance, no length of motion. So at rest the numerator of the speed is zero. Yet clocks tick on. The
In a paper titled Nothing but Relativity (Eur. J. Phys. 24 (2003) 315-319) Palash B. Pal derived a formula for transformations between observers that is based on the relativity postulate but not a speed of light postulate. In a paper titled Nothing but Relativity, Redux (Eur. J. Phys. 28 (2007) 1145-1150) Joel W. Gannett presented
