It gives them a picture in their head
Three types of scientific models are conceptual, mathematical, and physical models. ~Ares
computer
Because computer models can show results of experiments - without risking harm to people. For example, a computer can simulate what would happen when combining drugs for specific treatments - without harming patients.
physical,mathemtical,and conceptual are the types of models used by scientist
Some modern computer systems, such as the iMac, incorporate the program system and observe into a single system. In this case, the observe is part of the program system. While notebooks also have built-in shows, they are not called program models, since the term only represents personal computer systems.
Scientist are always testing their models to get new information or results, but other times learning evidence makes scientist have to change their models so scientist can change their models in theory.
They DON'T have to. They use models to save time and money - but the results are always tentative.
no!
computer have helped scientist to store data
They use computer models to show how this new evidence supports formation of a supercontinent long before Pangea.
Scientists collect data, in all sorts of ways using computer models math observing data, it all depends what kind of scientist.
