Models

Computer Modeling

Computer Modeling (or simulation) is using a computer to model or simulate a system. Using computers to model complex concepts in math or physics is particularly helpful. Due to the great power of creating and simulating models, many people put a lot of weight in the statistics that computers can generate. Because of this, it is easier to skew the accuracy of the results of modeling systems on computers to mislead the general population.

Modeling in Science and Engineering

Modeling is extremely helpful in science and engineering. Using computer models, scientists can help stop disease through massive computations distributed over millions of computers, improve transportation by making it easier to test [1] , or predicting global warming. By using the computer, scientists can accomplish massive amounts of computation in a much shorter time and more accurately than they could without computers. However, the results of computer modeling are not always as accurate.

Modeling how global warming will affect the future has fueled a lot of worry about the future of the planet, but the model might not be entirely accurate. [2] Because global warming is such a hot political topic, the inaccuracies of a model for it come to light. A model's accuracy and precision is heavily dependent on the accuracy and precision of the input feeding it. Scientists and laypeople should be aware that computer models are not inherently accurate.
