The presentation, divided into 30 slides (though only the first 10 are summarized here), begins by posing the question: \"What is modeling?\" It then delves into a specific problem: \"How do bike gears work?\" and tackles the related question of why climbing hills is easier in a lower gear. The solution, according to the presentation, lies in \"COGS\" (likely referring to cogs or gears). The document explains that this principle is \"precisely how clocks work!\" However, it highlights a limitation of this qualitative explanation: its inability to be measured, tested, or used for predictions. The presentation concludes by asking \"What do scientists do?\" and answering, \"What do scientists sell? Ideas!\" The core message revolves around the transition from qualitative understanding to quantitative modeling, emphasizing the scientific process of developing testable and predictive ideas.","Jambor􀀓e Meetup 2015  \n@ IFSC-USP-Brazil July 18th 2015  \nModeliGEM 1 / 30  \nWhat is modeling...?
