1 00:00:05,200 --> 00:00:14,920 (Music) 2 00:00:15,720 --> 00:00:20,080 Scientists use models often times to try to answer questions and they can use 3 00:00:20,080 --> 00:00:24,820 physical models or they can use computer-generated mathematical models. 4 00:00:24,820 --> 00:00:29,380 Both are trying to help us better understand something by adding a lot of 5 00:00:29,380 --> 00:00:34,690 complex information and seeing how it performs so to speak. So a physical model 6 00:00:34,690 --> 00:00:39,010 we imagine as something that we could hold in our hand and if we make changes 7 00:00:39,010 --> 00:00:43,899 to it we would visually see how those changes happen. In a mathematical model 8 00:00:43,899 --> 00:00:48,579 it's actually pretty similar but how we're seeing is through the language of 9 00:00:48,579 --> 00:00:54,219 math instead, and we use that data to then make a picture of what those 10 00:00:54,219 --> 00:00:57,280 changes are. 11 00:00:57,520 --> 00:01:23,960 (Music)
