"If you can't explain it to a six year old, you don't understand it yourself." - Albert Einstein.
If you read my other posts, you should understand by now how much clear communication means for me. How important it is. If your goal is to be understood, telling exactly what you mean and leaving out all the fluff and fancy words is the way to go.
I'm not saying there is no space for writing to be an art, but that it should only be an art if it is aims for the reader's enjoyment, with conveying a message being something secondary.
The need for simplicity isn't exclusive to written/spoken messages. It should also be a goal for every other form of communication, for example all the formulas, equations and laws used in maths and physics, code for computer programs...
I'll focus on physics now, because it's the subject I'm more comfortable with, but what I'm about to say applies to every other subject. What's the problem with it? It's just a pile of "we know this" that barely anyone understands, inconsistent, full of cheap tricks to make everything work. As long as everything gives the expected results, no one cares about understanding it and improving on it.
This situation is not sustainable. We need outsiders to get into it easily, we need to get young students up to speed a lot faster and we need who's inside to understand what they're doing, so that we don't have rockets randomly exploding every now and then. Basically physics needs a clean up to become Physics: a subject that is easy to understand, in-depth and produces accurate results.
"Simplicity is the ultimate sophistication." - Leonardo da Vinci.
Simplicity is one of the hardest things to archive. It requires people to differentiate accurately what is fundamental and what's not, to understand the topic from inside out. But is also one of the most valuable ones, maybe the most valuable one.
As simple as that. Thanks for reading!
