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
In a recent post, I defined levamentum as the lenticity divided by the mass (or times the vass). Here I show that levamentum is conserved, as momentum is. I will do this in 1D with a result that may be generalized to 3D time. Consider the equation of motion for a particle: (1/m) dℓ/dr =
From the day-long Lincoln-Douglas debates in 1858 to the proliferation of newspapers in late 19th century long public arguments took place. That gradually declined as radio came in, then television, and public attention became increasingly divided. Sound bites replaced extended speech in the public mind. The power of images replaced the power of words. Public
A previous post entitled Assertions contains the following “Motivating Example”: According to the Gospels, there was an inscription above Christ on the cross which said (in English translation): Matthew (27.37): “This is Jesus, the King of the Jews. ” (ABD) Mark (15.27): “The King of the Jews.” (D) Luke (23.38): “This is the King of
The kinematics of 3D duration (3D time) have been explored here over the past year. Now let’s look at the dynamics of 3D duration. This will be done in 1D in order to allow generalizations to 3D length or 3D duration. Start with momentum, the mass times velocity: p = mv. According to Newton’s second
My favorite computer game was the old Moon Lander game. It simulated a moon lander firing retro-rockets to safely land on the moon. The player controlled how much fuel was used, and the object of the game was to land safely and quickly, before fuel ran out. In this game the amount of fuel and
Harry Lee Poe, in See No Evil: The Existence of Sin in an Age of Relativism (Kregel, 2004), regarding the third chapter of Genesis writes: “When the woman saw that the fruit of the tree was good for food (the good), and pleasing to the eye (the beautiful), and was also desirable for gaining wisdom
You can measure distance by time. How far away is it? Oh about 20 minutes. But it doesn’t work the other way. When do you get off work? Around 3 miles. – Jerry Seinfeld Actually, you can measure time by distance, as was done above but expressing the time by distance requires that time be
