Note: previous posts on this topic are here and here. Motion flows. That is, there is always motion independent of us. We can also make standard motions that are effectively independent of us. They are called clocks. They can be used as standards of comparison to measure other motions. Clocks are needed for synchronous measurement […]
My previous posts on this topic are here, here, and here. I am indebted to John P. McCaskey’s writings on the subject of induction (see here). In this post I want to make the connection between the principle of the uniformity of nature with naturalism. In the 18th century there was a decline in understanding
Although there are three dimensions of length and three dimensions of duration, I have pointed out before that we measure movement as either 3D length + 1D time (3+1) or 1D stance + 3D duration (1+3) or 1D stance + 1D time (1+1). The (1+3) perspective is the focus of this post. The measurement of
I have a “metric cube” which is a decimeter-sized cube that was used in the 1990s to promote the metric system: It was useful to hold 90mm discs but could also be used as a 3D ruler to measure length in three dimensions at the same time. One could instead use a 1D ruler three
“All truth is God’s truth” is a common paraphrase of Augustine of Hippo’s writings, such as On Christian Doctrine, (II.18): “A person who is a good and true Christian should realize that truth belongs to his Lord, wherever it is found, gathering and acknowledging it even in pagan literature, but rejecting superstitious vanities and deploring
I’m returning to a topic I wrote about here: time in ancient culture and thought. Look at Genesis 1, verse 3: And God said, “Let there be light,” and there was light. And God saw that the light was good. And God separated the light from the darkness. Now a modern person is thinking spatially
2016 presidential candidate Clinton’s remark that half of her opponent’s supporters are “a basket of deplorables”, which means they are “racist, sexist, homophobic, xenophobic, Islamophobic”, triggered strong negative reactions. Calling millions of ordinary citizens such names shows more about the speaker than it does about the apparent referents. There must be a new acronym here;
This is a summary of posts (such as here and here) about the application of relativity theory to transportation. This is different from applying theories of physics to other subjects such as economics since here it is real relativity, not some analogy. However, the application is an approximation, but that is the nature of transportation,
I’ve written about history and science before (here, here, here, and here) because I think it’s important to understand their differences and relationship. History and science are complementary, which means they are in some way opposite but they fit together to make a whole. It also means they cannot be merged into one another, but
What would it mean for space to be one-dimensional? It would be similar to 1D time. Imagine a clock, except that instead of marking durations, it marks distances. It’s like an odometer for a vehicle that moves at a constant speed and never stops. Like this with units of distance (metres, kilometres, miles, etc.):
