This week marks the 43rd anniversary of the infamous Roe v. Wade decision of the U.S. Supreme Court legalizing abortion on demand. The annual march supporting the right to life will take place in Washington, DC. No doubt some political gestures will be made by supporting politicians. I certainly support the right to life but I […]
If we drop a stone into a calm body of water, it sends out circular waves. As the waves move outward, the clock is ticking and we say the dropped stone caused the waves, which are an irreversible process in time. But we would also say the waves are moving in space, so why isn’t
This is a continuation of the series of posts on the duality of space and time. Consider an isolated system of particles over a period of time. The system covers a specific distance in space and a specific duration in time. Consider only one dimension of space and one dimension of time with an origin point. The second
Christendom was a Christian culture and civilization that, historically speaking, began with Constantine. It started to divide with the Great Schism between East and West in the 11th century. It divided again with the Protestant Reformation beginning in the 16th century. It further divided during the Enlightenment movement beginning in the 18th century. Christendom has so divided
Although specific sciences have their methodological differences, there is a general scientific method that applies to them all. While some aspects of it are well-known, others are not. Here’s a summary: Specify a chunk of reality to focus on. It must be remembered that each science cuts off an aspect of reality. Gather data about the chunk
As (spatial) velocity and acceleration are vectors, so are their temporal analogues. This perspective makes sense because of the multiple dimensions of time. There is an implicit recognition that time has directionality since time is commonly considered as any real number, and not a non-negative real number, which it would be if time were merely
The speed of an object is the ratio of distance (or length) traveled and the duration of travel. It is derived from the distance traveled during a given duration. It is expressed as the measured distance divided by the given duration, that is, distance relative to duration in units of distance over duration, e.g., m/s, km/hr, etc. For example,
The homogeneity and isotropy of space are well-known. The homogeneity of time is partly known but is confused by an “arrow of time” concept that is not applicable to space and time. The isotropy of time is unknown (and usually denied) also because of confusion with an inapplicable “arrow of time” concept. I previously wrote about the
This post is another in a series on the duality of space and time. I have emphasized that the basis for space is length and the basis for time is duration. What, then, about direction? Does direction apply to both space and time? Yes, and in the same manner. If someone says, “The hotel is 10 minutes away by
This post is a continuation on the duality of space and time. The basis of space is distance (or length) and the basis of time is duration. It must be emphasized that both distance and duration are scalars, i.e., they have magnitude but no direction. They are not one-dimensional because that would entail direction, represented by
