Zeno springs to mind, but we digress.Well not so ... I looked closer at the article.
There are "Limits".
Consider a period of time after either midnight or midday and describe that as being AM or PM. Halve that time and there still is a time AM or PM.
Halve the resultant time and continue halving the resultant times and it is still either AM or PM. Eventually that amount of time will approach zero and we have a notional 12am or 12pm being effectively real.
Differential calculus is how we engineer aircraft or build Plaza Premium lounges.
I caught QR914 last week and could only peer through the locked doors of the lounge.
