Computer simulations

Definition

Computer simulations are digital models that use algorithms and mathematical representations to replicate real-world processes and systems. They allow scientists to analyze complex phenomena, such as planet formation and evolution, by modeling various scenarios based on different variables and initial conditions. This technology is crucial for testing hypotheses and visualizing outcomes that would be difficult or impossible to observe directly.
