I suppose college experience is like anything else: It depends on three things: the courses you take, the college you go to, and your attitude. The latter is probably the most important.
What tha &@#$ did I step in?!paphioland said:Thomas,
Typing this sounds rude but it is not my intention.
If you read about Chaos theory and Heisenberg's uncertainty principle you should better understand what I'm saying.
http://www.societyforchaostheory.org/tutorials/#1 said:WHAT IS CHAOS THEORY? Chaos theory is one of a set of approaches to study nonlinear phenomena. Specifically, chaos is a particular nonlinear dynamic wherein seemingly random events are actually predictable from simple deterministic equations. Thus, a phenomenon that appears locally unpredictable may indeed be globally stable, exhibit clear boundaries and display sensitivity to initial conditions. Small differences in initial states eventually compound to produce markedly different end states later on in time. The latter property is also known as The Butterfly Effect. Chaos has a close relationship to other dynamics, however, such as attractors, bifurcations, fractals, and self-organization.
http://en.wikipedia.org/wiki/Uncertainty_principle said:In quantum physics, the Heisenberg uncertainty principle or the Heisenberg indeterminacy principle — the latter name given to it by Niels Bohr — states that one cannot measure values (with arbitrary precision) of certain conjugate quantities, which are pairs of observables of a single elementary particle. The most familiar of these pairs is the position and momentum.
here are some different viewspaphioland said:There is no scientific determinism period. Until the uncertainty principle is dissproven that is the truth.
http://en.wikipedia.org/wiki/Scientific_determinism said:Physicists have sometimes used the term "determinism" in a special way that people such as Karl Popper and Stephen Hawking have called scientific determinism.
Popper insisted that the term "scientific" can only be applied to statements that are falsifiable. Popper's book The Open Universe: An Argument For Indeterminism defines scientific determinism as the claim that ...any event can be rationally predicted, with any desired degree of precision, if we are given a sufficiently precise description of past events, together with all the laws of nature, a notion that Popper asserted was both falsifiable and adequately falsified by modern scientific knowledge.
"These quantum theories are deterministic in the sense that they give laws for the evolution of the wave with time. Thus if one knows the wave at one time, one can calculate it at any other time. The unpredictable, random element comes in only when we try to interpret the wave in terms of the positions and velocities of particles. But maybe this is our mistake: maybe there are no positions and velocities, but only waves. It is just that we try to fit the waves to our preconceived ideas of positions and velocities. The resulting mismatch is the cause of the apparent unpredictability." (conclusions section of A Brief History Of Time)
well . . .paphioland said:. . . You can break down aspects of the environment, but, you can't add them together and figure out causally how they interact. So (while) you can say in a small system that co2 raises the temperature to a certain degree in a vacuum with a certain percentage of certainty, there is usually a very small percentage of uncertainty (built in).
. . . then that's probably why quantum mechanics isn't used to forcast weather. There are apparently differently methods of meteorology other than deterministic. Try this link:paphioland said:At best deterministic meteorlogy is an art/science, like medicine. Actually, it is much more comlicated than medicine. Physics tries to use knowledge to predict how complicated systems act, and, then predict the future, (an art.) If you threw quantum mechanics into the measurements, you are in for a world or uncertainty do to the probalistic nature of how small particles interact.

The methods range from simple traditional statistics and scores, to methods for more detailed diagnostic and scientific verification.

What is "truth" when verifying a forecast?
The "truth" data that we use to verify a forecasts generally comes from observational data. These could be rain gauge measurements, temperature observations, satellite-derived cloud cover, geopotential height analyses, and so on.
In many cases it is difficult to know the exact truth because there are errors in the observations. Sources of uncertainty include random and bias errors in the measurements themselves, sampling error and other errors of representativeness, and analysis error when the observational data are analyzed or otherwise altered to match the scale of the forecast.
Rightly or wrongly, most of the time we ignore the errors in the observational data. We can get away with this if the errors in the observations are much smaller than the expected error in the forecast (high signal to noise ratio). Even skewed or under-sampled verification data can give us a good idea of which forecast products are better than others when intercomparing different forecast methods. Methods to account for errors in the verification data currently being researched.
paphioland said:Just because you can measure these things there is huge error when you add all the measurements up . . . If you start making the system larger and more complicated, requiring trillions of measurements, the error is astounding. . .There is still error in our measurements but they are usually insignificant for what we need them for.

those were a lot of ideas in your post. Let me try to organize by showing some, um, neat things I found on the web (I'm just not smart enough to use my own words)
Chaos theory
Scientific Determinism

i lifted some of your coments so they make sense to me:
Lance Birk said:I will also support Rush Limbaugh, who I heard quote a passage from my Paphiopedilum book last week. Rush speaks continuously about moral and traditional values. I have never heard him speak anything but truth. He, also, is highly intelligent and is undeservedly criticized by people who neither know him nor listen to him.
