Measurement Determines Possibilities

---

The title might suggest that accuracy in measurement leads to accuracy in results, but there's a deeper truth at work: how you choose to measure fundamentally shapes what you observe.

Physicist Arthur Eddington illustrated this with a story about fishermen who caught fish using a net with specific-sized holes. After examining their catch, they concluded there was a minimum size to fish in the sea—never considering that smaller fish simply slipped through their net undetected. This parable reveals a profound insight about observation itself: the instruments and methods we select don't merely record reality; they actively filter and construct it.

Our tools of measurement don't just quantify the world—they determine which aspects of it become visible to us in the first place.
