dude Peak Oil definitely is not superstition. There is a mountain of empirical evidence. The United States formerly the worlds biggest producer of oil hit oil peak in the 60s (or the 70s?). There is evidence to suggest that we will reach Global peak in the next ten years if we arent already in peak right now. Saudie Arabias reserves of oil are becoming increasingly deeper in the earth, they have to flush millions of litres of water into these great caverns to bring the oil and water further up to the surface. All the machinery needs oil to run, (and we need oil to make the machinery) Soon it will take the equivalent of one barrel of oils worth of energy to remove one barrel of oil out of the ground. |

something i came across whilst researching 911 nonsense.
------
You've been told that "evolution is just a theory", a guess, a hunch, and not a fact, not proven. You've been misled. Keep reading, and in less than two minutes from now you'll know that you've been misinformed. We're not going to try and change your mind about evolution. We just want to point out that "it's just a theory" is not a valid argument.
The Theory of Evolution is a theory, but guess what? When scientists use the word theory, it has a different meaning to normal everyday use.1 That's right, it all comes down to the multiple meanings of the word theory. If you said to a scientist that you didn't believe in evolution because it was "just a theory", they'd probably be a bit puzzled.
In everyday use, theory means a guess or a hunch, something that maybe needs proof. In science, a theory is not a guess, not a hunch. It's a well-substantiated, well-supported, well-documented explanation for our observations.2 It ties together all the facts about something, providing an explanation that fits all the observations and can be used to make predictions. In science, theory is the ultimate goal, the explanation. It's as close to proven as anything in science can be.
Some people think that in science, you have a theory, and once it's proven, it becomes a law. That's not how it works. In science, we collect facts, or observations, we use laws to describe them, and a theory to explain them. You don't promote a theory to a law by proving it. A theory never becomes a law.
This bears repeating. A theory never becomes a law. In fact, if there was a hierarchy of science, theories would be higher than laws. There is nothing higher, or better, than a theory. Laws describe things, theories explain them. An example will help you to understand this. There's a law of gravity, which is the description of gravity. It basically says that if you let go of something it'll fall. It doesn't say why. Then there's the theory of gravity, which is an attempt to explain why. Actually, Newton's Theory of Gravity did a pretty good job, but Einstein's Theory of Relativity does a better job of explaining it. These explanations are called theories, and will always be theories. They can't be changed into laws, because laws are different things. Laws describe, and theories explain.
Just because it's called a theory of gravity, doesn't mean that it's just a guess. It's been tested. All our observations are supported by it, as well as its predictions that we've tested. Also, gravity is real! You can observe it for yourself. Just because it's real doesn't mean that the explanation is a law. The explanation, in scientific terms, is called a theory.
Evolution is the same. There's the fact of evolution. Evolution (genetic change over generations)3 happens, just like gravity does. Don't take my word for it.4 Ask your science teacher, or google it. But that's not the issue we are addressing here. The Theory of Evolution by Natural Selection is our best explanation for the fact of evolution. It has been tested and scrutinised for over 150 years, and is supported by all the relevant observations.
Next time someone tries to tell you that evolution is just a theory, as a way of dismissing it, as if it's just something someone guessed at, remember that they're using the non-scientific meaning of the word. If that person is a teacher, or minister, or some other figure of authority, they should know better. In fact, they probably do, and are trying to mislead you.5
Evolution is not just a theory, it's triumphantly a theory!

1 Theory: A set of statements or principles devised to explain a group of facts or phenomena, especially one that has been repeatedly tested or is widely accepted and can be used to make predictions about natural phenomena. American Heritage Dictionary
2 Scientific theories are explanations of natural phenomena built up logically from testable observations and hypotheses. Teaching About Evolution and the Nature of Science - National Academy Press
3 A standard, scientific definition of evolution is: In fact, evolution can be precisely defined as any change in the frequency of alleles within a gene pool from one generation to the next. Biology - Helena Curtis and N. Sue Barnes, W H Freeman
4 Evolutionists have been clear about this distinction between fact and theory from the very beginning, if only because we have always acknowledged how far we are from completely understanding the mechanisms (theory) by which evolution (fact) occurred. Darwin continually emphasized the difference between his two great and separate accomplishments: establishing the fact of evolution, and proposing a theory - natural selection - to explain the mechanism of evolution. Evolution as Fact and Theory - Stephen Jay Gould
5 The Cobb County School Board required a sticker with the following text to be placed on all biology textbooks: This textbook contains material on evolution. Evolution is a theory, not a fact, regarding the origin of living things. This material should be approached with an open mind, studied carefully, and critically considered.

Idiot's guide to calculating pi/2 for ancient civilizations.
Tyrone has a bunch of crack rocks to build a pyramid.
He knows how tall he wants his crack rock pyramid to be (He got lucky and all the rocks are the same size and he wants his pyramid to be ten crack rocks high...).
1) He stacks up 10 rocks on top of each other. Drops a rope from the top, and cuts the rope at the bottom. This rope is now equal to the height.
2) Cut rope in half. (No need to measure, just join the 2 ends of the rope, and cut the loop.) This is so height = diameter, radius is half of that.
3) Put a stick in ground. One end of the rope attached to stick. With other end, use this to draw a circle in the sand/dirt/whatever.
4) Get another rope, and cut it to the size of your awesome circle. Amazing, he has the circumference! (pi x diameter!)
5) Cut this new rope in half. Rope should now be equal to PI/2 of the original height. Use this for length of base. Same ratio as used by khufu. Except, this is Sparta
Nothing but.. rope. Not even pi.
I never want to hear again in my life that pi is over the head of the ancients. |

ofcourse it was terrorists.. just maybe not the terrorists we're thinking.. ;) |

not sure if someone else has already mentioned this
but if you want to get all excited, google nibiru and 2012. |

| lol @ the "scientists" of this thread, so quick to bash the hell out of people who talk of a higher being. its like scientists are more defensive about religion, than religious people are about science. |

haha, its funny you should mention that!
9/11 conspiracy theories act is the same way as creationist theories - not by providing proper evidence, but attempting to poke holes in accepted facts.
scotty, i can honestly tell you that there is no doubt at all concerning the larger story - it went down more or less how represented by the various levels of government and private enterprise say it did.
sure- there could be questions of responsibility concerning foreknowledge or certain agencies really dropping the ball either before or during the attacks. certainly the bush admin's hawks capitalised on it to go on their nation-building escapades.
but the idea that the US government planted explosives in the towers is just ridiculous, and violates any and all levels of common sense. but let's not discuss it further, ive spent hundreds of hours typing about that in the PDD :( |

the difference being that scientists will never ever stop you from believing whatever the hell you want ;)
i have no problem with people that believe in a deity of one kind or another. i get a problem when they say things like "evolution is only a theory" as if there is an equal amount of doubt concerning evolution when compared to the existence of god. |
