CORE DEFINITION

In contrast to the Heisenbug, this refers to stable, reproducible bugs. Just like Bohr's atomic model, the position is determined; whether you observe it or not, it is there.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

Prioritize deterministic issues. When solving complex crises, first address those 'certain' and 'obvious' Bohrbugs. Don't go after the elusive Heisenbugs right away, as that will drain your energy.

Anchor fast decisions

Bohrbugs are stable and reproducible; their trigger conditions are deterministic, and debugging is not disturbed by observation. In contrast, Heisenbugs change or disappear with debugging intervention (e.g., adding logs). Fixing deterministic bugs first yields quick returns and reduces system uncertainty.

Second Law of Thermodynamics

The second law of thermodynamics is one of the four fundamental laws of thermodynamics, stating the irreversibility of thermodynamic processes—isolated systems spontaneously evolve toward thermodynamic equilibrium, the state of maximum entropy. Similarly, a perpetual motion machine of the second kind is impossible. The history of this law can be traced back to Nicolas Carnot's research on the efficiency of heat engines and his Carnot theorem proposed in 1824.

Coherence

In physics, coherence (also called phase coherence) states the possibility of interference between two waves. Two monochromatic beams from the same single light source always interfere with each other. If two wave sources have the same frequency and waveform, they are coherent. The physical sources of coherent waves are not strictly monochromatic; they may be partially coherent. However, beams from different physical sources are mutually incoherent.
