That > qualifies you as a looser; doesn't it? NoEinstein I'm fascinated by this idea you have of winning or losing. We're having a discussion about physics. I'm explaining to you what we know matches experiment, and what the definitions of the words are that are used in physics, what the equations mean, and how that is exemplified in measurements, and the fact that none of what we're talking about is beyond 7th grade science level. You on the other hand seem to be more worried about winning some kind of battle or contest, and to you winning means: - that you talk longer than anyone else, ensuring that you always have the last word - that no one can *force* you to believe what 7th graders have no difficulty understanding - that no one can *force* to you stop talking - that you stick by your guns, no matter what, regardless of how stupid it starts to sound even to you - disparaging your respondents by calling them negativists and other assorted names - that you have offered a retort to every single response to your posts. By that metric, someone who firmly believes that 17+4=32, and who insists on this long after the last person has walked away, and who insists that 2nd grade math teachers are obviously wrong, and who is proud that no one has been able to get him to stop saying 17+4=32, and who calls people who believe otherwise to be ninnies and brainwashed -- well, by golly, in your eyes that person has won something. Of course, 17+4 is not 32, but the IMPORTANT thing, you see, is winning, not being right. Isn't that so? As for attacking you, you'll pardon me if I'd decline to hire you to be the architect for a doghouse. I'm sure you understand my reasons why.

NoEinstein I'm sorry, John, but you're going to have to look at a physics book, not a dictionary of common usage, for the definition of a term as used in physics. For example, a field in physics does not typically contain corn or wildflowers. In physics, the velocity over an interval is del(x)/del(t), where del(x) is the displacement over the interval del(t). So if del(t) is the preceding second, then del(x) is the displacement during that preceding second. You will find this very clear definition boxed and highlighted in just about any high school physics book. Since you claim to have gotten a degree in architecture, you would have had to pass an exam at one point demonstrating your understanding of that definition. You either have forgotten it in the intervening 92 years, or you never learned it. In either case, since you don't even understand the definition of velocity and displacement as used in introductory physics, you'll understand why I'd be very nervous about any structures that you have designed, and I'm glad your city in South Carolina declined your advice on the design of its public structures. > > > > > > On Apr 30, 5:38 am, NoEinstein <noeinst...(a)bellsouth.net> wrote: > > > > On Apr 28, 10:50 pm, PD <thedraperfam...(a)gmail.com> wrote: > > > > > On Apr 28, 9:08 pm, NoEinstein <noeinst...(a)bellsouth.net> wrote: > > > > > > On Apr 27, 10:16 am, PD <thedraperfam...(a)gmail.com> wrote: > > > > > > > On Apr 26, 9:42 pm, NoEinstein <noeinst...(a)bellsouth.net> wrote: > > > > > > > > On Apr 26, 1:30 pm, PD <thedraperfam...(a)gmail.com> wrote: > > > > > > > > Dear PD, the Parasite Dunce: Your denseness makes you incapable of > > > > > > > understanding that NO force is required to cause an object to COAST. > > > > > > > I do understand that.

You simply take the anti-thesis of any science truth, knowing that there are some naive readers who won't know the difference. It may sound 'high-and-mighty' for you to keep referring to... the experimental evidence, and the 'textbook' definitions, but you NEVER paraphrase a possible counterargument. You only claim that there is 'something', somewhere that disagrees with me. And you expect me to go look that up. Folks, PD is the deep thinker (sic) who said that atomic decay is a "chemical reaction". And just today, he said that a car which is COASTING isn't increasing its "displacement". He has just proposed that... "displacement" is only apt to calculating, or measuring, an object's unit velocity. And since the unit velocity of the car doesn't change, he claims that coasting isn't increasing the distance of travel of the car. Can't most of you see how little PD cares about truth and logic? Does he think everyone but him is a fool? *** Tell us this, PD: How many science experiments, of any kind, have YOU designed, built, and successfully tested? I've made two most definitive tests which support the LOGIC that Coriolis's KE equation is not only WRONG, its so obviously in violation of the Law of the Conservation of Energy, that no experiments are needed, at all, to disprove: KE = 1/2mv^2; nor to similarly disprove E = mc^2 / beta. For you, a proof is only valid if it involves experiments which you have never cited, nor paraphrased, and definitions that you claim are in textbooks, but which you never quote. I recently told you that I had suspected that the readers agreed with my correctness our yours by two to one. But in light of your recent statements of utter stupidity, that number is probably closer to ten to one! *** No scientist on Earth has more credibility than yours truly. *** If any think that they do, I would love for them to go head-to-head with me, so that I can kick their asses into solar orbit. Like those purported scientists, you, PD, dont have a leg, nor a stump to stand on.

Yes, indeed, because physics is not something that is settled by puffed-up posturing and debate. It is not something that is determined by force of logic. You may be confusing physics with philosophy. Ultimately, the truth in physics is determined by careful and independently confirmed experimental measurement. That body of experimental evidence is documented and available to you. It is referred to in textbooks, and references to it have been made here to you. So yes, you are expected to look it up. ANYBODY doing physics is expected to look it up. > > Folks, PD is the deep thinker (sic) who said that atomic decay is a > "chemical reaction".

Are you sure you want to ask this question? My professional history is as an experimental physicist, and my record is public. Please don't puff yourself up as a songwriter when talking to a professional musician. It's not smart to put on airs as an expert on law when talking to a judge. > I've made two most > definitive tests which support the LOGIC that Coriolis's KE equation > is not only WRONG, its so obviously in violation of the Law of the > Conservation of Energy, that no experiments are needed, at all, to > disprove: KE = 1/2mv^2; nor to similarly disprove E = mc^2 / beta. > For you, a proof is only valid if it involves experiments which you > have never cited, nor paraphrased, and definitions that you claim are > in textbooks, but which you never quote. Two comments: 1. Your experimental results will be worth something when confirmed by an independent investigator. That is how it is done in science. Until then, you are a self-feeding loop. 2. Yes, I expect you to look up textbooks, as they are easy to find even in your local library. I'm assuming that you are not under house arrest, you aren't bedridden, that you have bus fare to get you downtown, and that you are capable of reading when you get there. I'm also assuming that you are not so pathologically lazy that you refuse to budge your butt from your chair. > > I recently told you that I had suspected that the readers agreed with > my correctness our yours by two to one.

This is just like you, to suspect something is true without a single shred of tangible evidence.
