Depth is a topic that is too deep for some folks. When information is collected for measure, the depth of measure indicated how far we can trust our analysis. In the weigh - the deeper you go down the depths of the rabbit hole, the more support is required from the background of your current beliefs. When i talk about knowledge, there is a difference between relative knowledge and absolute knowledge that requires address - science pretends to address only absolute knowledge and sometimes sees things through aquamarine colored glasses.
The depth that you know a topic is dependent on the amount of time spent gaining expertise in the area. We all have different learning curves and different means of getting learning across. By continually plugging at a topic and looking at it through many visual, auditory and ambiance based perspectives, we can determine our reality to the depth necessary to explain most phenomena. Conflict occurs when concepts cannot be transferred fractally; the incongruence toward as above, so below becomes readily apparent after a few iterations.
To know something well is to study it in depth for a significant number of hours. There are also mechanisms where people can get complete downloads in a novel area in a very short period of time through alternative means. What you believe should be internally consistent with your weigh of thought. If you come to a point where something is no longer making sense - the time has come to design an experiment that evaluates the alternatives. You set up a test and measure the results.
In science, results are probability distributions. In chemistry, the yield is based on a theoretical 100% yield being the perfect use of all the molecules of the limiting agent - a highly improbable event under any circumstance. Sometimes, 15% is a very good yield, especially for multi-step processes. By learning how to coordinate your hands with your skills, you get a feel for how to do chemistry and small changes in technique can significantly improve yields. To get there though, you have to be doing the labwork and spending the hours that it takes to get the skill sets right.
Seems to me that it would be this weigh in any profession. There is a basis set of information that has to be learned and then the rest can be derived from the weigh the pieces are reformed into parts. The skills reach a level where you just know - you no longer need to refer to the books on the shelf, because you already know your topic well enough to know what the books say. There is confidence in knowing a topic in more depth than anyone - there may also be a tendency to make it up at the edges.
Einstein once said that imagination is more important than knowledge. The time has come to reevaluate the imagination base from a variety of perspectives in great depth. There are things that we fully believe that just are not true. There are also things that we fully disbelieve that are true, nonetheless. There are borders on our depths, such that the physical integrity of the whole does not add up the pieces of the whole in any weigh that fits the 'real' pattern - in today's amerika it is the reel pattern that the media wants us to believe. What do we know? How do we know?
If i no longer think that something is right, i slide it off into my flux box and try not to use the concept again until i have rectified the challenge that had me disturbed. I sometimes get beyond my depth and have to clarify some instances in other fields - often, i misinterpret what somebody means with a term that they chose to imply something that was not in my vocabulary. I have a miniscule vocabulary and know word derivation, so a misused specific term can be misinterpreted to mean what i think it means, rather than the speaker's proper definition. Often - the multiple meaning are also double entendres.
Too deep for me to go much further now. What we know, in depth, will be what sustains us, no matter the cause. Enjoy being - the journey is a important as the destination.
