Modeling the World

What is reality? It is something we can observe? A symbol is used to represent something or model an object or thing. A symbol is easily manipulated and created into something that is ubiquitous to all. For example, a sign of a kangaroo running and acting as if crossing the road, allows us to know that their could be kangaroo in the area and to be aware or that. Many have observed and explored symbols and how they relate more explicitly to the outside world. Those of who such as Lord Kelvin, Aristotle, Galileo, Hertz and more. They all worked to put the pieces together and theorize the knowledge. Physics was the first science to make precise formal theories of the world. Aristotle studied and observed factors that determine motion in signs. Bringing physics back in, he studied densities and the rate of motion. It was the first time that observable quantities had been expressed in symbolic or numerical form. Now the first form of calculations appears. Galileo studied primary information of such that can be mathematically measured. Things of measurement like sizing and shaping for example. Hertz defines a model as “Physical theory becomes about building relationships among observationally-derived symbols.” The process of modeling involves experiencing, reflecting, formulizing, and experimenting. Fibonacci and his Numbers introduced the first model. The equation or starting point is that B =A, and A= BA. With this pattern many different images and models can be produced. For example a plant or flower can exist with enough branching of A’s and B’s. Modeling is everywhere around us and can be tricky at times so be sure to be up to date with things.

Thats a nice summary of the lecture, but it would be nice to read some of your own ideas on what was discussed in the lecture-maybe you could come up with a simple model of something and describe it here?
