It really has been quite some time since I last posted. So far, I have spent two of four weeks this semester without a computer. 19 units/15 technical units is hell. It’ll be slow going on the blog. Instead of working on chem hw (which I really should be doing), I’ll post on this blog.
One thing to know about this world is that it is in a constant state of flux. Even the concept of change itself. Back in the day when things were easier, we used delta to denote a difference between one state at one time and another state at another time. Then we learned that we could make the interval on which we take that difference very small, and we replaced delta with d. After that we learned many different things could be changing at one time, and we could simplify things by holding all things steady but one, whose change was denoted with lowercase del. Finally, we realized that we could do that for each thing and superpose them all in a vector, defined as the gradient or uppercase del.
But really this says something about change. To summarize, there are multiple types of change (and we’re not talking about coins here):
-A specific difference between then and now. Delta. Potentially path independent; comparison-like.
Example: Great Britain was the eminent economic powerhouse in the 1800’s, the U.S. is now.
-A tendency of change at a moment of a particular thing. d/low del. Analytical.
Example: China is rapidly rising up from Third World status to become an eminent world power.
-Trends, gradients, the Big Picture. Upper del.
Example: Globalization and spread of information, technology, and ideas is rapidly transforming the global economy and the balance of power on the world stage.
So think about the concept of change, and delve into it a little more. What has happened in your life? Perhaps for some of you, college provides opportunities to examine each level of change more deeply.
