"I will try to express myself in some mode of life or art as freely as I can and as wholly as I can, using for my defense the only arms I allow myself to use -- silence, exile, and cunning." -- James Joyce
Yep!And while correlation does not imply causation, lack of correlation does not imply lack of causation.
Ehhhh. Burning fuel does not cause P to be any value, and is not claimed to. It is claimed to reduce P - V over a range of values. Adjusting the thermostat is what is claimed to cause P to move to a new value, again over a range of values. As ex hypothesi it is a good thermostat you will see good correlation between the reading and P.So this is not a good example of causation not leading to correlation:it shows good correlation between burning and P -V and on thermostat settings and P.
Ken, Nick was making a joke.
He was making a point with a funny example. I have seen NR repeat the caustion/correlation thing on other sites. But the point doesn't actually follow from the example.
Ah, now I see you misunderstood the analogy rather than failing to get the joke. Just what is "P - V"?
