1. The first class incorporates aspects of fundamental physics. These are properties
that are well known in the physical world, which include principles of energy, mass,
and earth's orbit. The second category includes theoretical physics that is well
known, but hard to measure and fully understand. This includes calculations of
particle movement through the atmosphere, incoming radiation, and ocean currents
and particle movement. Small factors like wind and clouds affect scientist's accuracy
in these measurements. The third class includes empirical physics, which is only
described through observation. This is very vague because it only incorporates
observable principles that cannot be explained prior to observation. These factors
definitely contribute the greatest uncertainty to models because they are not well
understood, and their driving factors are usually even less understood.
3. The Greenland Norse and the Inuit never developed a beneficial relationship.
They were mostly hostile toward each other, and the Norse were afraid of the Inuit,
considering them inhuman in some ways. Archaeological evidence of their
relationship shows that there was little trade between the two peoples. The Norse
used no harpoons, spears, or kayaks. Some Norse items were found in Inuit areas,
most likely as a result from fighting, kidnapped Norse, or stolen items. The Norse
never took the time to learn from the Inuit, a group of people who knew how to
survive in Greenland. They did not hunt the same food or use the same tools. This
was the main contributing factor to the Norse downfall. Had they taken the time to
trade with the Inuit, they may have learned valuable hunting techniques which were
critical in a place where crops were scarce.
