In everyday life 1D space and 1D time are typically used. We are concerned with how far away something is (travel length), how long will it take to get there (travel time), what the speed is (apart from direction). Unless we are doing something in which size or direction are important, 2D is all we […]
A geometric (or geometrized) unit system is a system of natural units in which the base physical units are chosen so that the speed of light in vacuum, c, and the gravitational constant, G, are set equal to unity. Sometimes Coulomb’s constant, ke, and the electric charge, e, are also set to unity. The General
This is a continuation of what I wrote on this topic here. IV Apart from time zones and daylight savings time, noon means midday, the time that the sun is directly overhead, when the sun crosses the meridian. Is noon the time when the sun is directly overhead or is vertical the direction of the
As I’ve shown, there are three dimensions of time as well as space. That makes six dimensions in all, which I’ve written about before, such as here. There may be reasons to use the full potential six dimensions but usually it is better to contract that to four or two dimensions. We need terms to
It has been thought best to introduce new terms for temporo-spatial physics since although in some respects the concepts are similar to standard terms of physics, in other respects they mean the opposite to those of space-time physics. Here is a compilation (updated 2021): lenticity (len·tic′·i·ty) is the rate of change of dischronment with respect
Note: terminology updated Apr. 2021. See glossary above. Isaac Newton’s three laws of motion and law of gravity apply to space-time, the 3D space (spatiocosm) with 1D time of classical physics. What do these temporo-spatial laws look like, with 3D time and 1D space? Newton’s space-time laws of motion state: Law I: Every body continues
First, you know, a new theory is attacked as absurd; then it is admitted to be true, but obvious and insignificant; finally it is seen to be so important that its adversaries claim that they themselves discovered it. William James in his book Pragmatism These three phases can already be seen in explicating 3D time,
We’ve all seen a vehicle speedometer, scaled in km/h or mph like this: A paceometer is made by adding another scale, as with the outer scale of minutes per 10 miles below (image source here): Fitness apps on smartphones can display distance traveled, travel time, and pace. In the article Pace yourself: Improving time-saving judgments
How practical is the mechanics of time-space? It’s at least as practical as the mechanics of space-time and in some case is easier to understand or more appropriate. This post begins a series to illustrate this based on the website Physics: Problems and Solutions, Kinematics. Problem 3 A car travels up a hill at a
Temporo-spatial physics parallels spatio-temporal physics. Here is a derivation of the corresponding equations of motion, paralleling the exposition at the Physics Hypertextbook. The one-dimensional equations of motion for constant relentation: Let t = time, t0 = initial time, r = displacement, u = lenticity, u0 = initial lenticity, b = relentation. First equation of motion
