A. I am very nostalgic. I am nostalgic about the present. This is because I live in the future. There isn’t anything futuristic or daydreaming about it. I look forward to the life and times that will follow. So as I write this grammatical ‘tense’ that I use in my sentences it may seem a bit confusing.
B. I am very nostalgic. I live in the past. Hence my present existence, my day-to-day life is a futuristic living. Again, there isn’t anything futuristic or daydreaming about it. I look back at life and times lived, happy ones and right ones I cherish, sad or painful or wrong ones I learn from.
Two situations, two positions I give not to confuse, not to fuse. They are to pose a hypothesis. Then there will be a thesis building upon it and from there, as a reaction or response, will come up an antithesis. The churning of the ideas will finally throw up a synthesis. That will show us some concrete results. Let’s see. Let’s begin… To bother just about the present is very mean. Those who say they are concerned only about the present, who live in it and work for it and thereby take pain to put themselves up as practical persons and realists are in reality hypocrites or are ignorant – more often the latter.
How I see this issue is probably a more broad way of looking at things. Our present – how we are, how we live, what we are doing now – has already become. It is what had to be and what is being. We cannot do anything about it except the fact that only we can control and direct it further in our desired way which is yet to come. It is in this sense that I said “I live in the future.” In actuality, in this sense, everyone lives in the future. So I again clarify we live for the times (yet) to come, we live for the moment that will follow now, and we always live into the next moment that follows. What we are in is already happened. So what is – has been (already).
We are constantly and endlessly losing into the past, what we have right now – say this in any frame or dimension, time and space are objects or thoughts or experiences. Using the terms in our already discussed sense, the past – what has already been, is eternal, and the future – what has to be, is eternally potential. So truth is the past, truth is in the future. ‘Present’ is nothing but a zero-sum total stage of transformation of the past to the future and has in itself (and is) no time duration at all but zero – no time factor at all.
We can visualize this interesting thing in a sort of pictorial illustration. Let’s take a space-time dimensional graph. There is a null point where the axes of the graph pass or meet. In this whole network ‘present’ is when it touches or crosses the zero point but is never stationary at zero. And this present exists only then and there and nowhere else, never otherwise. Thus it exists but has no length or dimension elsewhere on the graph.
That is why there is no reality when one says that one lives only in or for the present, existing at the same time without living in the past and the future in the continuum. Thus in man’s consciousness about this aspect, everyone lives as I do, in the future – and the past lives, always – within me or without me. This is the reality of the present and that is the eternity.
We use calculations as a method to solve mathematical problems, including equations of calculus. Calculus, on the other hand, is a mathematical process for solving problems relating to the rate at which objects change. So calculations are methods while calculus is a process that uses those methods.
Calculus is the mathematics of dynamics, of change and of motion. These are of two types: Differential calculus is about finding the rate of change of a function; and, Integral calculus is finding the function when its rate of change is given.
One can read them in terms of Deductive Logic and Inductive Logic as well..
