Physics. I did like physics. I do like physics.
There is a fascinating meta-learning about this field. In physics not all laws our theorems work at every scale. Newton’s equations work very well to explain and model the behavior for most every day phenomena. Trains accelerating, apples falling from trees, water rushing down with pressure from a water tower.
Newtonian physics do break down though at different scales. They don’t work well for very small objects, neither for the very large, or the very fast. That’s why physicists came up with quantum mechanics and with the general theory of relativity.
It is not that Newtonian physics are wrong, and that suddenly we should toss them out the window. It is only that they happen to be a very convenient simplification that works well for many common cases.
This very same scale paradigm applies to doing business. There are general rules and concepts for business, but their implementation will look very different for a small 10-individual startup, than for a 10,000 employee corporation. For example, efficiency, or record keeping, are good for any size of company, we get it. But being efficient in a startup may mean going through your to-dos, and reacting to customer inquiries ASAP, at a larger corporation, you may have to tweak a process, to shave off a few seconds for hundreds of agents. At a large corporation, a Content Management System may be necessary, and even people in-charge of curating it, at a smaller organization, just scrolling back on your WhatsApp may be just enough.
Adjust for scale.
