eytelwein.main.constants module

Physical and mathematical constants for the Eytelwein package.

This module provides physical constants with proper units using the Eytelwein unit registry, ensuring dimensional consistency across calculations.

All physical and mathematical constants are sourced from scipy.constants for scientific accuracy and future-proofing.

Note on naming conventions:

We use “STANDARD_GRAVITY” rather than just “GRAVITY” for several reasons: 1. Scientific Precision: It specifically refers to the internationally defined constant

value of 9.80665 m/s², rather than local gravitational acceleration which varies.

  1. Physical Reality: Actual gravity varies across Earth’s surface - it’s stronger at the poles (9.83 m/s²), weaker at the equator (9.78 m/s²), and decreases with altitude.

  2. Engineering Context: For conveyor belt calculations, the standard reference value ensures consistency regardless of location.

  3. Naming Convention: This follows established naming patterns in scientific libraries and engineering standards.
