Evolution posts

Evolution for everyone The word evolution is related to the terms evolve and evolute, and originally meant an unrolling. It acquired a sense of development in the 19th century and was associated with progress, especially as promoted by Herbert Spencer. Charles Darwin used it in print only once since his theory was not a theory […]

Basic Gospel

Basic Gospel Message Vic Scaravilli is a Catholic who put the following on his website here. I’m reposting it (with permission) and note that Evangelicals would agree that this is the gospel, with some nuances about baptism. The Basic Gospel Message By Vic Scaravilli God loves each one of us. He loves me and He

Design and evolution

I last wrote about design here. What is the essential element of a design? Dictionaries define design in terms of a plan but that concerns how a design is recorded or communicated rather than the design itself. I suggest that the essential element of a design is the necessity of a trade-off. To define a

Generic units of measure

Customary units of measure such as the foot and the pound are suitable for everyday purposes such as measuring the dimensions of a person or a room. Metric (SI) units of measure such as the Kelvin and the kilogram are suitable for scientific purposes. Some metric units are suitable for everyday use, and they are

New fallacies

There are several online lists of fallacious arguments: Fallacies, Full alphabetic list of fallacies, Logical Fallacies Handlist, List of fallacies, List of Fallacious Arguments, and especially Master List of Logical Fallacies, A list of Latin names is here. Aristotle categorized rhetorical strategies under ethos, logos, and pathos. Ethos is an appeal to credibility or authority.

Motion and axes

This post continues from the previous post here. All motion is axial. It is a principle of kinematics that every motion is composed of the simple motions of translation and rotation. These simple motions are either along an axis (translation) or around an axis (rotation). Here is a table of these two simple motions: Motion:

Motion measurements

As described in the previous post here, the three dimensions of motion are axes for traveling along (length) or revolving around (time). A measure of motion may be either (1) dependent on the the target motion, or (2) independent of the target motion. A measure that is independent is either available prior to or separately

In the beginning is reality

In the beginning is reality. That is, reality precedes us. We discover reality. We don’t invent reality. “Wonder is the only beginning of philosophy.” (Socrates in Plato’s Theaetetus 155d) “For it is owing to their wonder that men both now begin and at first began to philosophize.” (Aristotle, Met. 982b12). We wonder about reality. That

Motion coordinates

As a thought experiment, consider a rifle bullet, conceived of as an inertial projectile, fired at a target. Let the bullet itself be a source of measurement units: there is the length of the bullet and the rotation of the bullet. The extent of the motion of the bullet to the target could then in

Dual Lorentz Transformation

Victor Yakovenko has a derivation (see here) of the Lorentz Transformation (LT) in which he uses “only the equivalence of all inertial reference frames and the symmetries of space and time.” Because of the use of (length) reference frames and velocity, this is not completely symmetric. As we have seen, there is a dual Lorentz
