Then the old hypothesis is rejected and a new is formed. For instance: "all swans are white or blue." This hypothesis will probably in time be rejected as well. ect, ect. This all means that one can never be sure if a hypothesis is fully true, for we do not know if it will ever be proven wrong. A hypothesis can only be proven wrong.

In other words, if you freed yourself from the church, the next step is to get free from the "science" bla bla. - I know you wanted to explain how scientist work, I wanted to explain how scientist think, and that they are still only human beings, emotional and 99percent of the time irrational.

Scientist Posted April 4, 2002 fodders said:With the hypothesis all swans are white, upon being confronted with a blue swan, a true scientist would not reach hypothesis "All swans are white or blue" but "Swans are not always white"© The hypothesis "Swans are not always white" would not be a good scientific hypothesis. The reason for it is that this statemant cannot be proven wrong. It is simply always correct. A hypothesis should be able to be tested and falsified. There's no point in running experiments on the hypothesis "Swans are not always white". The hypothesis would always be maintained, it's not specific enough. I can hear you wondering: Why do Scientists say things like "All swans are white or blue (or black)" while they know this could be proven wrong in the future? Why wouldn't they say "Swans are not always white"? A statement with is always 100% correct. Doesn't science seek 100% truth? The answers to these questions: Yes, Science seeks 100% truth. The thing is HOW they claim to find it: Science admits that you cannot trully know something is CORRECT (like all swans being white). But you can know if something is INCORRECT (a blue swan proofs not all swans are white). If we know all that is incorrect, what remains is all that is correct. So by increasing the quantity of all the things we know are incorrect, we're getting closer to pure correct statements. This is the way science works. I admit it's a complicated way to get to true knowledge. And even if Science would bring us real true knowledge this way Science could not proof it to be real true knowledge. This is because Science cannot proof things to be right only wrong. It would never accept true knowledge as real true knowledge, but just as a hypothesis that has not (yet) been proven wrong. I can't think of a better path the true knowledge, pretty depressing actually, but it's the best way man has come up with, with his limited intellect. 0 Share this post Link to post
IMJack Posted April 4, 2002 A better way to put fod's stateent (logic-wise) is "There exists at least one swan that is not white. "True knowledge" is an oxymoron. It's true that the Scientific Method is the process of methodically seeking contradictions to existing theories, and applying the results of experiments to revise theories. That Has Been Established (TM). But it's not the search for true knowledge so much as it is the search for explainations for the natural world. I mean, all the scientific knowledge in the world is no good if you don't know how to do anything with it.

fodders Posted April 4, 2002 Problem: To Catch a Lion in the Sahara Desert. 1. Mathematical Methods 1.1 The Hilbert (axiomatic) method We place a locked cage onto a given point in the desert. After that we introduce the following logical system: Axiom 1: The set of lions in the Sahara is not empty. Axiom 2: If there exists a lion in the Sahara, then there exists a lion in the cage. Procedure: If P is a theorem, and if the following is holds: "P implies Q", then Q is a theorem. Theorem 1: There exists a lion in the cage. 1.2 The geometrical inversion method We place a spherical cage in the desert, enter it and lock it from inside. Case 1: The lion is inside the cage. This case is trivial. Case 2: The lion is outside the cage. We then perform an inversion with respect to the cage. Then the lion is inside the cage, and we are outside. Warning: With this method, it is important not to stand in the middle of the cage, as one will disappear in the infinite. 1.3 The projective geometry method Without loss of generality, we can view the desert as a plane surface. We project the surface onto a line and afterwards the line onto an interior point of the cage. Thereby the lion is mapped onto that same point. 1.4 The Bolzano-Weierstrass method Divide the desert by a line running from north to south. The lion is then either in the eastern or in the western part. Let's assume it is in the eastern part. Divide this part by a line running from east to west. The lion is either in the northern or in the southern part. Let's assume it is in the northern part. We can continue this process arbitrarily and thereby constructing with each step an increasingly narrow fence around the selected area. The diameter of the chosen partitions converges to zero so that the lion is caged into a fence of arbitrarily small diameter. Warning: With this method take care that the beautifull skin of the lion is not damaged. 1.5 The set theoretical method We observe that the desert is a separable space. It therefore contains an enumerable dense set of points which constitutes a sequence with the lion as its limit. With a cage on our backs, we jump from point to point of this sequence an so approach the lion as near as we like. 1.6 The Peano method In the usual way construct a curve containing every point in the desert. It has been proven [1] that such a curve can be traversed in arbitrarily short time. Now we traverse the curve, carrying a spear, in a time less than what it takes the lion to move a distance equal to its own length. 1.7 A topological method We observe that the lion possesses the topological gender of a torus. We embed the desert in a four dimensional space. Then it is possible to apply a deformation [2] of such a kind that the lion when returning to the three dimensional space is all tied up in itself. It is then completely helpless. 1.8 The Cauchy method We examine a lion-valued function f(z). Be \zeta the cage. Consider the integral 1 [ f(z) ------- I --------- dz 2 \pi i ] z - \zeta C where C represents the boundary of the desert. Its value is f(zeta), i.e. there is a lion in the cage [3]. 1.9 The Wiener-Tauber method We obtain a tame lion, L_0, from the class L(-\infinity,\infinity), whose fourier transform vanishes nowhere. We put this lion somewhere in the desert. L_0 then converges toward our cage. According to the general Wiener-Tauner theorem [4] every other lion L will converge toward the same cage. (Alternatively we can approximate L arbitrarily close by translating L_0 through the desert [5].) 1.10 The Mathematical Induction method Consider, for each n, the following statement: P(n) : 'It is possible to catch n lions in the desert.' Of course, P(n) is true for large enough n, because the lions are then so tightly packed together that it is easy to catch them. But now, P(n) implies P(n-1) ('cause if you catch some lions, you can always release one of them). Hence, P(1) is true. 1.11 The Banachsche or iterative method Let f be a contraction of the Sahara in it with contraction point x_0. On this point we put the cage. By successive iteration W(n+1)= f(W(n)), n=,1,2,..... (W(0)=Sahara) the Sahara will be contracted to X_0. In this way the lion will get in the cage. 1.12 The Kalra Method Make a list of the lion's whereabouts. Classify them into different fuzzy sets. The lion will get confused and fall into your trap. 1.13 The Cartesian method Take the origin as close as possible to the lion. Then perform rotation operation again and again. Initially, the lion will feel dizzy. Finally it will fall down. 1.14 The Inductive Method Initial Condition: If you center a large cage on any one grain of sand, and a lion is on or close to the grain of sand. then he will be trapped by the cage. By close we mean within epsilon grains of sand. Given a cage the size of 2 * (size of lion * epsilon) it works. First Hypothesis: Given the first grain of sand in the desert, if the lion is standing on it you will trap him. Proof: Given by the initial condition. Induction Hypothesis: Assume that a lion is on a grain of sand n, and is trappable. Now, for grain n+1 (assume all grains of sand are ordered, inorder) n+1 is close to n, hence n is close to n+1. If the lion is on grain n, and is trappable; then he is close to n+1, and by the above condition, trappable. Hence, no matter where the lions are if you drop a cage centered on a piece of sand you will catch a lion. 1.15 The Integro-Differential Method Integrate the Sahara over its entire surface. The lion is now somewhere in the result. Differentiate the result w.r.t the earth's rotation. The resulting value is zero, and the lion is no more. 1.16 Group theory method Note that "dog in lace" is an anagram of "caged lion". Therefore, apply the appropriate permutation from S9 on a dog in lace to obtain a caged lion. The matter of obtaining a dog in lace is left to the reader. 2 Theoretical Physics Methods 2.1 The Dirac method We assert that wild lions can ipso facto not be observed in the Sahara desert. Therefore, if there are any lions at all in the desert, they are tame. We leave catching a tame lion as an exercise to the reader. 2.2 The Schroedinger method At every instant there is a non-zero probability of the lion being in the cage. Sit and wait. 2.3 The Quantum Measurement Method We assume that the sex of the lion is _ab initio_ indeterminate. The wave function for the lion is hence a superposition of the gender eigenstate for a lion and that for a lioness. We lay these eigenstates out flat on the ground and orthogonal to each other. Since the (male) lion has a distinctive mane, the measurement of sex can safely be made from a distance, using binoculars. The lion then collapses into one of the eigenstates, which is rolled up and placed inside the cage. 2.4 The nuclear physics method Insert a tame lion into the cage and apply a Majorana exchange operator [6] on it and a wild lion. As a variant let us assume that we would like to catch (for argument's sake) a male lion. We insert a tame female lion into the cage and apply the Heisenberg exchange operator [7], exchanging spins. 2.5 The Newton gravitation method Cage and lion attract each other with the gravitation force. We neglect the friction. This way the lion will arive sooner or later in the cage. 2.6 The Newton third law method Let the lion catch you (let's assume you remain alive here). For every action there is an equal and opposite reaction. Therefore, you will have captured the lion. 2.7 The Special relativistic method One moves over the desert with light velocity. The relativistic length contraction makes the lion flat as paper. One takes it, rolls it up and puts a rubber band around the lion. 2.8 The Special relativistic method (method 2) Run in the direction opposite to that of the lion. The relative velocity makes the lion run faster and hence he feels heavier and gets tired. 2.9 The general relativistic method All over the desert we distribute lion bait containing large amounts of the companion star of Sirius. After enough of the bait has been eaten we send a beam of light through the desert. This will curl around the lion so it gets all confused and can be approached without danger. 2.10 The Heisenberg method Position and Velocity from a moving lion can not be measure at the same time. As moving lions have no physical meaningfull position in the desert, one can not catch them. The lion hunt can therefore be limited to resting lions. The catching of a resting, not moving lion is left as an exercise for the reader. 2.11 The Schroedinger cat method 1) Note that a lion is nothing else than some big cat. 2) Pour some contact poison that's lethal to lions over the Sahara. 3) Thereafter, either the lion is dead, or it isn't. So look at the Sahara to reduce the lion's state to either dead or alive. If he's dead, you will have no problems picking him and putting him in the cage. If it is not, proceed back to step 2. 4) Since the probability (P) of this trick working is not 0, and since [limit, on n going to infinite, of 1 minus P to the nth, is O] you've got 1OO% probability of some iteration of the process bringing up the result you wanted. There could just be a snag about the method : if the lion is dead, obvioulsy he's not moving anymore, and his momentum is known to be nought, so how are you going to measure where he is lying ? 2.appendix The Heisenberg constriction You will disturb the lion when you observe it before capturing. So keep your eyes closed. 3 Experimental Physics Methods 3.1 The thermodynamics method We construct a semi-permeable membrane which lets everything but lions pass through. This we drag across the desert. 3.2 The atomic fission method We irradiate the desert with slow neutrons. The lion becomes radioactive and starts to disintegrate. Once the disintegration process is progressed far enough the lion will be unable to resist. 3.3 The magneto-optical method We plant a large, lense shaped field with cat mint (nepeta cataria) such that its axis is parallel to the direction of the horizontal component of the earth's magnetic field. We put the cage in one of the field's foci . Throughout the desert we distribute large amounts of magnetized spinach (spinacia oleracea) which has, as everybody knows, a high iron content. The spinach is eaten by vegetarian desert inhabitants which in turn are eaten by the lions. Afterwards the lions are oriented parallel to the earth's magnetic field and the resulting lion beam is focussed on the cage by the cat mint lense. [3] According to the Picard theorem (W. F. Osgood, Lehrbuch der Funktionentheorie, vol 1 (1928), p 178) it is possible to catch every lion except for at most one. 4.1 The search method We assume that the lion is most likely to be found in the direction to the north of the point where we are standing. Therefore the REAL problem we have is that of speed, since we are only using a PC to solve the problem. 4.2 The parallel search method. By using parallelism we will be able to search in the direction to the north much faster than earlier. 4.3 The Monte-Carlo method. We pick a random number indexing the space we search. By excluding neighboring points in the search, we can drastically reduce the number of points we need to consider. The lion will according to probability appear sooner or later. 4.4 The practical approach. We see a rabbit very close to us. Since it is already dead, it is particularly easy to catch. We therefore catch it and call it a lion. 4.5 The common language approach. If only everyone used ADA/Common Lisp/Prolog, this problem would be trivial to solve. 4.6 The standard approach. We know what a Lion is from ISO 4711/X.123. Since CCITT have specified a Lion to be a particular option of a cat we will have to wait for a harmonized standard to appear. $20,000,000 have been funded for initial investigations into this standard development. 4.7 Linear search. Stand in the top left hand corner of the Sahara Desert. Take one step east. Repeat until you have found the lion, or you reach the right hand edge. If you reach the right hand edge, take one step southwards, and proceed towards the left hand edge. When you finally reach the lion, put it the cage. If the lion should happen to eat you before you manage to get it in the cage, press the reset button, and try again. 4.8 The Dijkstra approach: The way the problem reached me was: catch a wild lion in the Sahara Desert. Another way of stating the problem is: Axiom 1: Sahara elem deserts Axiom 2: Lion elem Sahara Axiom 3: NOT(Lion elem cage) We observe the following invariant: P1: C(L) v not(C(L)) where C(L) means: the value of "L" is in the cage. Establishing C initially is trivially accomplished with the statement ;cage := {} Note 0: This is easily implemented by opening the door to the cage and shaking out any lions that happen to be there initially. (End of note 0.) The obvious program structure is then: ;cage:={} ;do NOT (C(L)) -> ;"approach lion under invariance of P1" ;if P(L) -> ;"insert lion in cage" [] not P(L) -> ;skip ;fi ;od where P(L) means: the value of L is within arm's reach. Note 1: Axiom 2 ensures that the loop terminates. (End of note 1.) Exercise 0: Refine the step "Approach lion under invariance of P1". (End of exercise 0.) Note 2: The program is robust in the sense that it will lead to abortion if the value of L is "lioness". (End of note 2.) Remark 0: This may be a new sense of the word "robust" for you. (End of remark 0.) Note 3: From observation we can see that the above program leads to the desired goal. It goes without saying that we therefore do not have to run it. (End of note 3.) (End of approach.) 4.9 The Linked List Method Make a linked list of all objects in the desert. Then delete the pointers on either side of the lion.(Make sure you are not AFTER the lion.) 4.10 The Automata Method Use a Non-Deterministic Finite Automaton with epsilon moves from all states to the final state, and no moves from the final state. The lion will soon enter the final state and be trapped. 4.11 The Divide And Conqure Method (by recursion) Divide the desert in half. Repeat the process until you have the lion, a grain of sand, or some other object that cannot be divided without blood shed. You have the lion. The order of this method = O(insane). (Where sanity is anything reasonable.) 5 Other Methods 5.1 The Time-Cop Method Use a time-machine and take the entire Sahara back a few years in time. The lion is just a cub now, and all you need is a mouse-trap. 5.2 The Shakespeare Method Hold the lion still for a moment (I don't care how you do it), and recite Shakespeare`s Hamlet to it. The lion will change from 'To be' to 'Not-to-be'. 5.3 The Pentagon method. Construct a safe, secure cage and leave the door open. Alternate massive B-52 strikes across the Sahara desert with subtle propaganda campaigns emphasizing the safety and security of your cage. When a lion enters the cage, close and lock the door. 5.4 The supply-side method. Distribute vast quantities of lion food and eliminate all threats to the lion population. Put a cage in the desert and wait for the explosive growth of the lion population to force a lion into the cage. 5.5 The Marxist-Leninist method. Indoctrinate the gazelle population of the Sahara desert in dialectical materialism. Disguise your cage as a re-education camp for capitalist lions, and the gazelles will bring you all the lions you need. 0 Share this post Link to post

Executor667 Posted May 16, 2002 fodders said:Such is the concept of anarchy, only it is a hundred times more trusting that Communism. Anarchy places all faith in people, without the benefit of a police force. Let us take an example: Mr. and Mrs. Farmer lead a bucolic life. They live in harmony with the land, growing and storing food in the warm months and living off their stash in the winter. One winter, their neighbors, the Sapiens family, finds out that it does not have any food. Seeing no other chance at survival, they kill the Farmers. Since there is no police force, there was no fear of punishment for the Sapiens. Someone had what they wanted, and they took it. It would only become worse from this point. Once the entire population learned that there wold be nobody to punish them for wrongdoings, the world would go to hell. Chaos, yes. And it is almost certainly a chaos in which those high-school vandals would not survive. It would be a Darwinian system all over again. Survival of the fittest. Or, put more bluntly, survival of the meanest. Those kids who promote anarchy would be dead within a month, with no cars, no TV, no microwaves. The power would certainly not work. What would keep people working at a power station when they could just take what they wanted?... EXACTLY! Humans are selfish, cutthroat, greedy arseholes if there is no government to keep them in line. This basic tendency of humans is why Cardinal Bernard Law is covering up the church pedophilia that is occurring in his archdiocese. He is a greedy pig who loves his red hat so much that his obsession with power (the cardinals elect a new pope when the old pontiff dies, and they have a huge amount of power over the church members in there archdioceses) has overwhelmed his conscience. If you are a cardinal, you don't want bad publicity. And even though Cardinal Law has plenty, he won't resign. He refuses to give up the funny red hat that sits atop his head. What about the Pope? Can't he just excommunicate him? Yes, but the Pope doesn't care, and it would cause even more bad publicity for the Catholic Church because the press would try to uncover more dirty little secrets and spew out whistle-blowing scandal stories like there's no tomorrow. It's much safer to mumble a few lines of rhetoric and forget about the pedophilia. 0 Share this post Link to post
