In order to provide realistic output, scientific models
Vilhelm Bjerknes saw "no intractable mathematical difficulties" with predicting the weather, and many numerical models have been built since he wrote those words in 1904. Even with the best of those models, our weather predictions are still frequently incorrect. Why?
Why is climate particularly well suited to research using modeling rather than other methods like experimentation?
Hydrologists have developed a computer-based model to simulate flow of a contaminant through a groundwater reservoir. In order to develop their model, the hydrologists most likely
Physical "ball-and-stick" models are often used to represent molecules, even though scientists agree that atoms are not like billiard balls and bonds are not like sticks holding them together. Why do you think these are still used?
The first step a scientist takes in developing a model – conceptual, numerical, or physical – is to define the system that the model is meant to represent. Which of the following statements best describes a system?
Computer models are superior to physical models because they are more quantitative.
