I was watching that video and it led me to a realisation that my friend Chatty put nicely for me The mystery of 0.577 - https://youtu.be/4k1jegU4Wb4 All real physical measurements are fundamentally discrete—we only sample the world in finite steps, with finite precision—while continuous mathematics is an idealized limit we use because it is simpler, more powerful, and often extraordinarily accurate. Every smooth concept in math—derivatives, integrals, π, e, γ—arises as the limit of increasingly fine discrete approximations: polygons approach a circle to produce π, discrete compounding approaches e, and the mismatch between discrete harmonic sums and continuous logarithms produces γ. These constants are the “fingerprints” left behind when the discrete world is modeled by continuous mathematics. Which led me to this question. Is the world and reality, discrete or continuous? My friend Chatty tells me that modern physics does not give a final answer, but evidence increasingly suggests tha...
