1. The laws of motion: These observable facts describe the behavior of objects in motion and reveal underlying principles about the way that they are affected by forces and the way that they move through space.

2. The laws of thermodynamics: These observable facts describe the behavior of heat and energy and reveal underlying principles about the way that these quantities are conserved and transformed within a system.

3. The principles of quantum mechanics: These observable facts describe the behavior of particles on a very small scale and reveal underlying principles about the wave-like nature of matter and the uncertainty principle.

4. The structure and function of cells: These observable facts describe the way that cells are organized and the processes that they carry out, and reveal underlying principles about the way that cells function as the basic units of life.

5. The mechanisms of evolution: These observable facts describe the way that living organisms change and adapt over time, and reveal underlying principles about the way that evolution occurs and the factors that influence it.

6. The principles of ecology: These observable facts describe the relationships between living organisms and their environment, and reveal underlying principles about the way that ecosystems function and the way that they are affected by external factors.

7. Patterns of behavior: These observable facts describe the way that individuals or groups behave in different situations, and reveal underlying principles about the way that behavior is influenced by external factors or internal states.

8. Trends in social attitudes or beliefs: These observable facts describe the way that attitudes or beliefs change over time, and reveal underlying principles about the way that these attitudes or beliefs are shaped by social, cultural, or political factors.

9. The dynamics of power and influence: These observable facts describe the way that power and influence are distributed within a system, and reveal underlying principles about the way that these dynamics shape the behavior and relationships within the system.
