Correction, no one has used the Williams developed flywheel KERS system in F1. Every car to have run KERS to date has used a battery based system.

In any case, Porsche has demonstrated the flywheel based system and is going to use it in a production vehicle shortly.

Please stop underestimating the capability of engineers to DO THEIR JOBS......all the people on here talking about the safety need to go ahead and say out loud "i don't want to goto the 80th story of this building because, jeebus, I just don't know if they could make buildings that are that tall safe"...and then realize that your common sense is trumped by their engineering ability!

At nearly every stage of perception from the actual impingement of the environment on our perceptual apparatus all the way through to our actual experience of the worlds, there occurs some level of "processing" or rather transformation.

Point is, what you experience is very removed from the 'reality of the world' if you will. The most obvious visual examples relate to color processing or motion processing (i.e. how different shades of gray can appear the same, or how you can look at those spirals and see motion in your peripheral vision)...but this happens for all of the ways that we perceive and experience.

Yay for philosphy :)

but how do we know if the methods of education have improved? currently tests are considered one of the most useful metrics of measuring the success of those methods. Unfortunately, as we all know, this has led to teachers "teaching the test" and little else.

Consequently, the solution, is to reduce the emphasis on the test and place more emphasis on the judgement of teachers.

You're going to have to present a stronger case than "if you read the paper that they publish, they talk about error margins."

Error margins are introduced because they do not have the computing power (nor models of sufficiently good quality) to compute every molecule in the atmosphere. Instead they have to divide the planet into a grid of cells, then model the cells as the smallest unit in the simulation. The processes that occur within these cells are only approximated and not actually computed, therefore there is some margin of error. This is typical practice for simulations and doesn't prevent them from being highly accurate.

Furthermore, scientific theories yield predictions, "which then turn out to be false" ALL THE TIME. In fact it too is standard practice for the field of science. Science never establishes certainty, it just hopes to paint the most accurate picture possible (nevermind the specifics of what accurate means (to save me from writing a philosophy of science essay to inform you some more)).

At the end of the day your argument that the simulations outstrip the predictory power of the data is refuted. Not only don't they exceed the data, but they've been increasing the quality of their data on a daily basis.

PS- you may be interested to note that some climate models have refuted existing data, which initially was taken as evidence against the model, until scientists figured out that the model was more accurate than the data! Turns out the weather balloons they were using were sensitive to atmospheric conditions which influenced the readings they generated. Sometimes models are more accurate than the data!
