simulation
sim-yuh-LAY-shun
/ˌsɪm.jəˈleɪ.ʃən/
The imitation or computer modeling of the operation of a real-world process or system over time.
Focuses on realistic replication of physical flight conditions for pilot training or scenario analysis.
The story behind the word. Derived from Latin 'simulare' (to copy or make similar), rooted in 'similis' (like). Originally associated with feigning illness or imitating behavior, the 20th century transformed the term into a core scientific discipline of building digital and physical mock-ups of real flight dynamics.
Word relationships
- modeling: Modeling creates mathematical representations, whereas simulation dynamically executes those models in real time.
- emulation: Emulation exactly replicates hardware behavior, while simulation imitates physical system responses.
- reality: Actual real-world conditions rather than replicated ones.
Commonly confused with
- Dissimulation: Dissimulation means hiding your true motives or feelings, whereas simulation means modeling a real-world physical process.
Word family
- simulate (verb): To imitate the appearance or character of something.
- simulator (noun): A machine that simulates environmental conditions.
Collocations
- flight simulation
- computer simulation
- run a simulation
- high-fidelity simulation
Example sentences
- "Flight crews undergo rigorous emergency simulation exercises in full-motion simulators every six months." Pilot Training
- "Computer simulation of aerodynamic forces allowed engineers to predict boundary layer turbulence before building a prototype." Engineering Analysis
Memory hook
SIMILAR -> SIMULATION: making something SIMILAR to the real thing. Similar to reality.
When not to use
Do not confuse with deliberate deception or fraudulent pretense in social settings.
Fun facts
- Modern Level-D flight simulators recreate turbulence and mechanical failures so accurately that pilots can earn full type ratings without flying a real jet first.
