In response to the most recent and ridiculous attempt at slandering my online presence, I'm not going to make the usual allowances for editing the quoted so as to make him seem more intelligent than in reality. This is, of course, so as not to place undue burden on my time, simply in regard to the massive number of hideous errors in grammar and syntax that the post in question contained. Hereafter, quotes will appear simply as originally written. Plus it just amuses me more to pretend to refute his non-arguments when every single word he writes is misspelled, incorrectly used, or totally invented. Enjoy. This is basically the same preposterous assertion that you rephrase in increasingly annoying, incorrect, and totally irrelevant ways, throughout the remainder of your rambling, incoherent response (everyone in this room is now dumber for having listened to it - Billy Madison is quite fitting here - at any rate, I award you no points, and may god have mercy on your soul). Whatever meaning you intend to be conveyed by your apparently pivotal term 'true weight' completely escapes any reader, as you never enumerate it. I can only imagine that by 'true' you meant to evoke 'constant' or some other equivalent concept. I certainly hope this is not the case, as that type of assertion would make your ignorance of the tenets of physics literally undeniable; weight is, by definition, not a constant, but rather a variable (which, for any particular massive body varies multiplicatively depending on the relative strength of the net gravitational force acting on that body at a time t). If you meant to argue against the common understanding that iron 'has' weight, you may have been able to actually contribute to the discussion. However, you neither advanced that argument nor contributed to the discussion in any other way. No, there is not only mass. The very relation you describe concerning mass under gravitational force is precisely what we mean when we use the word weight, and indeed provides for its conceptualization in the field of theoretical physics. Countless pertinent and indispensible equations in the science depend on the salience of considering weight in relation to other variables and constants which represent characteristics of massive bodies and other relevant forces. This is all, of course, not to mention the preposterous notion that iron could weigh more than air without having more mass. I can't imagine any other readers of my post thought for even an instant that this was the position for which I was arguing. Almost as importantly, weight is a more meaningful part of our collective vocabulary than mass, simply because the realm of social interaction for the most part takes place within the same field of gravity, rendering weight just as descriptive, if not more descriptive, than mass. Consider for a moment the fact that no one on earth knows their mass (in kilograms, generally) in any other way than by being 'weighed' on a scale that outputs its results in kilos rather than the actual property it was measuring - weight. When you thought for a fraction of a second that you might understand what I was saying, you were on the right track. Perhaps you should have forged ahead toward that understanding, rather than slamming your forehead repeatedly against a wall of ignorance. The fact that you resort to ad hominem attacks on my character further undermines the shaky ground on which your non-arguments are precariously balanced. Were I to respond in kind, I would notice that your username has the word 'god' in it, and accuse you of being a religious zealot. Basically, you may as well have made fun of me for having an 'oriental-sounding' username. I find this one even funnier because it's based on a simple misunderstanding of linguistic convention. It would serve you well to remember in future verbal exchanges that in english, the phrase "doesn't just" is used to indicate that what immediately follows is something that is already agreed upon, but that the speaker intends to convey an additional predication of meaning to the subject, beyond that which is already assumed to be agreed upon between the speaker and audience. To be specific, in the case concerned, I used "doesn't just" to indicate that, while I consider it agreed upon that iron has mass, it "doesn't just have mass," it "also" has weight. Note how the use of "doesn't just" was followed shortly by "also." This is something you can look out for, as it will denote the additional predication, which is generally the substance of the utterance. Furthermore, iron "doesn't just" have more mass than the surrounding gases which comprise the earth's atmosphere, it "also" weighs more in earth's gravitational field, which is why iron 'falls' toward the earth's surface when 'dropped.' As you can probably see by now, your entire post was not only arguing (I use the term perhaps so loosely here that it loses all meaning, but only for lack of a better word, as the mood of the post was clearly argumentative, whether it actually made one or not) for something that is both widely accepted and considered within this topic to be agreed upon, but was in the spirit of using me as a 'straw man' against which to argue your moot point. This is not only rude, but ignorant. I advise you to avoid this kind of self-denigrating and audacious behavior in the future. Even more interesting that this was the very next sentence. After just recently denying that objects have weight as well as mass, you immediately and explicitly assert that very fact. Not much needs to be said about the 'logic' (rather, the lack thereof) of this kind of 'argument.' However, it should be noted that size/shape are encapsulated terms in physics, making their independent consideration wholly irrelevant. That is to say, in physics, size and shape come as a package referred to as 'volume.' Keep in mind that in conventional language, two objects can be the same size (that is, in the language of physics, have mathematically identical values representing their respective volumes - reported in m̢̮â¬Å¡Ãâó or some other such unit) without having the same shape, but not vice versa; this gives you an approximate grasp of how size/shape interact in physics. Interestingly, objects that we would, in conventional language, say have the same shape, but not mathematically identical volumes, are not considered in the language of physics to have the same shape. They are, instead, considered to have 'analagous' shapes. This simply means that the two objects in question represent two instantiations of an archetypal possible shape, but at different and mutually exclusive points on the volume ratio gradient for that archetype (a sphere is one example of an archetypal shape). Furthermore, it is possible for such 'analogs' to have the same mass without being the same shape, so long as the object with less volume is appropriately more dense. This is how we make sense of the interaction between mass and volume - density; we take the units from mass (g, or some prefixed form of the unit), the units from volume (again, usually m̢̮â¬Å¡Ãâó), and when dividing the mass by volume to determine how dense the object in question is, we perform the same operation on the units of measurement, and report the object's density in g/m̢̮â¬Å¡Ãâó, for instance. This is, in essense, a meaningless jumble of angry words spilling out of your mind before you have a chance to consider their complete irrelevance to my post, not to mention the fact that these kind of accusations make a better argument against you as a credible source than against me. This is a grammatically misconceived and slightly misleading encapsulation of gravity, but is microcosmically correct in a few ways. However, words like 'pull' and 'down' are not exactly the most widely applicable, and you should point out that the figures you present here are strictly rough estimates of the force of gravity near the surface of our planet. The force of gravity is vastly different depending on what bodies are considered in relation to each other (you've heard of black holes, I'm sure; also known as 'gravity wells,' they produce forces which are quite a bit stronger than our earth's field; of course, due to their incredible density and resultant high mass). Also keep in mind that we most often consider the 'net force' of gravity; that is, the product of all the gravitational forces acting at a locus, reported as a vector. Though this is perhaps an extraneous consideration, it doesn't hurt to keep in mind that it's "not just" the earth which produces the gravitational field around itself. Also, when you mention 'friction,' I imagine you intended to refer to 'air resistance,' which, though undeniably similar to friction, is a wholly independent concept with its own unique properties. If this is what argument destruction looks like, I must admit that I'm seeing it for the first time. I guess I had imagined the idea of 'argument destruction' in a slightly different way. If I had to imagine what got you off on the wrong track, it would probably be shallow reading of my post, which resulted in your lack of comprehension and eventual misguided confusion. I think you made an attribution error common to young people who are just being introduced to the ideas of physics as a science. Often, it seems offensive to refer to the 'weight' of an object, when it is not a constant and universal value. The aspiring physicist thinks to himself, "Why not just use a constant - its mass value - instead?" What you need to remember is that the apparent absurdity lies in, for example, the idea of reporting the 'weight' of the entire earth in terms of the gravitational force it supplies to other massive bodies, because it is itself the massive body which produces the gravity used to determine weight values of bodies within its net field. However, this does not preclude the 'weight' of any component part of the earth itself from being accurately and productively considered. Even the 'potential weight' of the earth in its entirety (were it possible for the earth to 'weigh' within its own field) can be calculated by including values for its known mass and the force of its own gravitational field. Though this sort of calculation is certainly more possible than it is meaningful, it gets to the root of your confusion: on earth, the earth (in toto) does not have weight, since it is itself the source of the gravity which attributes weight to other massive bodies in its field; however, as soon as a front-end loader digs up a load of dirt, the portion of the earth contained in its bucket has a definite, meaningful 'weight' value. Moreover, the earth (in toto) does indeed have weight in relation to other massive bodies which exert gravitational forces on it. Though pounds as a measure of weight are a unit specific to the power of earth's gravitational field, they are still generally used when reporting weight for other systems of gravitational interaction. I assume this is simply because doing so remains the best way to keep discussion of such relations coherent and comprehensible to humans, who in large part spend their lives within earth's gravitational field. To clear up any confusion, I'm 26 years old. I have two university degrees, one of which is a bachelor of science degree. I am a published author and a contributor to several scientific journals. I do believe that bodies have mass. I also believe that massive bodies within gravitational fields have weight. Furthermore, I believe that iron cannonballs are just this type of thing - massive bodies within gravitational fields - and they have weight because of that fact. I like using weight values whenever possible, because they are more informative than mass values; they not only relay mass information, but also information regarding the strength of gravitational force present. They are most certainly a relevant and socially acceptable form of communication regarding the properties of objects we consider in discussions of this type. My advice to you, o young sage: enjoy high school while it lasts. Try to learn some things while you're there. Come back after you've taken some university courses - preferably in physics, metaphysics, epistemology, inorganic chemistry, sociology, rhetoric, semantics, linguistics, and for christ's sake, english - and read my posts again when you're ready to absorb their content. To everyone else: I'm looking for a group of dedicated individuals to critically read the post I've just quoted, with the aim of producing a categorized inventory of the total number of language errors committed within. PM me if you're interested in spending the rest of your life futilely parsing 'sentences' and attempting to determine the intended meaning of invented 'words,' toward an objective which will remain unrealized even long after your death. Good luck to all who apply.
