Inacurate Measurements?

The usefulness of a mathematical model for predicting may be limited by uncertainties in measurements, or by neglect of some important influences. A very in history or English, there are many acceptable answers. However, this may not be true. As there are many systems of measurement and not all are exact, there may be multiple answers for the same mathematical question. Also, due to all the different systems of measurement like the metric system, the International System of Units, or the system America uses, it is difficult to completely convert each number, as one system may measure it in another way. Plus, within the one system of measurement, there may be different ways of describing the same thing. For example, in the American system, one person may say twelve inches, but another may say one foot. This can also cause some discrepancies.

For example, I recall being a young child and trying to convert centimeters into inches and my teacher told me that that was virtually impossible, as there would be so many decimal points to consider. Therefore, I rounded my answer. Many numbers are rounded or estimated, which makes other numbers inaccurate. Also, due to repeating decimals or decimals that do not end, it is virtually impossible not to round the number, thus making it that more difficult for the number to be completely accurate. Although the numbers may be close to exact, it is virtually impossible for them to be perfectly exact.

Questions to consider:
1. If a system were put in place so that every country had the same measurement system, would this end certain discrepancies?
2. Do rounded or estimated numbers make inaccurate measurements?
3. Is it possible to have a measurement that is always the same, no matter what system is used?

QUESTIONS to CONSIDER about GAS

1. If gases did not act predictably, would there be a periodic table?
2. If gases are predictable, are solids and liquids also predictable?
3. Do gases always act in the same manner in a given volume or place, regardless of other factors?
4. If a gas acted unpredictably, would that lead to all new discoveries?

GASES Part 1

Gases respond in predictable ways to pressure, temperature, volume, and changes in number of particles. If gases were not predictable, there would be no periodic table. Scientists can normally predict, correctly, when a gas will react to certain changes, but so can people who are scientists. For example, almost everyone I know knows what will happen when you boil water; it will turn to vapor.
It is also well known that gas always turns to the form of its container. This means that is the container gas is in is round, the gas will fill up the entire round space. My father was telling me about an episode of “David Letterman” that he saw where a biker fueled his bike with soda cans. The soda was shaken up and the man blasted off. This was due to the pressure of the carbon in the cans.

CYCLES

In many physical, biological and social systems, changes in one direction tend to produce opposing, leading to repetitive cycles of behavior. This relates to how there are repetitive cycles to everything in the world. When there is a change in one cycle it will lead to an opposite cycle. This is true in really any cycle. In the physical world, this is similar to the process of precipitation. The precipitate or rain falls to the ground and is evaporated up into the air, where it is stored in a cloud. The cycle continues.
This also relates to positive and negative feedback loops, as learned in principle of biomedical sciences class. Feedback loops are cycles of behavior. They can be anything from cycles of electricity to cycles of blood in the body. Positive feedback loops change in a favorable way, meaning it is more of an expected result. Whereas in a negative feedback loop, the results are inverted.
Even life cycles are repetitive. Everything from human’s daily routine (we wake up, brush our teeth, eat breakfast go to work) to our histories (history repeats itself) are repetitive cycles. Therefore, everything is subject to the “domino effect.” One change causes an opposing behavior, restarting the cycle.

Questions to consider:
1. Does the change always produce an opposite; can there be a change with no repercussions?
2. Do all cycles break after some time?
3. Can a cycle be broken without using an opposing force?
