Observational constraints

Observation constraints are fundamental in shaping our understanding of the universe and how we formulate scientific theories. Here are a few key insights from experts on this topic:

1. Role in Physics:

   • Stephen Wolfram highlights that with just two constraints—being computationally bounded and the belief in persistence through time—our observations can align with major theories in physics like general relativity, quantum mechanics, and statistical mechanics. These constraints significantly shape how we perceive and interpret the world through the "ruliad" of all possible computational processes 1.

2. Interpreting Information:

   • Bert de Vries discusses how variational free energy minimization, subject to constraints, provides an optimal way of processing information. This approach helps in updating probability distributions in the face of new observations, which can be both direct measurements and more abstract constraints (e.g., body temperature ranges) 2.

3. Building Theories from Observational Evidence:

   • Sara Imari Walker emphasizes that groundbreaking scientific ideas often stem from closely working with observational evidence. For instance, Einstein's insistence on the constancy of the speed of light led to the theory of relativity. She argues that working backward from measurements to form theories leads to more radical and foundational shifts in understanding, like those seen in quantum mechanics and potentially in new areas such as assembly theory that aims to redefine life based on observable molecule complexity 3.
