A google search is sufficient verification of that. Plus I do believe I just mentioned that d = 1/2 at^2 + vt is a useful consequence of F = ma and you chose to ignore that and instead rant about jewish book publishers.

I haven't claimed to have disproved the WORD version of Newton's 2nd Law of Motion. *I've proved that his supposed equation, F = ma, isn't even an equation! I'll give you credit - that is a fascinating assertion. That is because "forces" (in pounds) can NEVER be equated to accelerations (in feet/second^2, [sic!])!! So John, did you _really_ just make that mistake? Force has units of [mass] * [length] / [time^2]. Just like F = ma says. Now, is the pound a unit of mass or a unit of force in imperial units? Were you not taught the metric system, or are you just so old that you don't give a ****? There's a reason the entire world minus the US has dropped imperial. I'm sure its' coincidence that it is next to impossible to find a system of units in use by a scientific paper that isn't a variation of metric. *You are from a class of psychos having the notion that you can increase your miniscule stature by trying to belittle others WITH statue in science. Who would that be, John? You are a psedononymous airmchair physicist who thinks he has 'disproved' F = ma. So you can not possibly expect me to believe that you have 'statue' [sic] in science. *Show the readers your status, Eric, by correctly answering this question: "Is it ever possible to get out 4 lbs. of hamburger after grinding up only 2 lbs. of steak?” *After you answer, or decline to answer, that question, no elementary school student will be holding YOU in high intellectual esteem. *— NoEinstein — That kind of question certainly does tell everyone the level at which you operate, doesn't it? |

It took quite a long time to disentangle Newton's strain of empiricism from the astronomical insights which make up planetary dynamics yet I discovered early on that empiricists just don't want to know,even when some prescient physicists attempted to introduce the geometric language of astronomy into the arena for discussion - " I challenge anyone to quote a single, solitary place where Newton in the Principia or elsewhere said F=ma. He was much too careful a man to assume the constancy of mass and never, but never, went beyond F = d(mv)/dt and never took the m out of the parenthesis as constant. That was done by the guesswork-loving intuitive physicists who lived after him. Of course, the Principia are not written in the language of algebra, but of geometry." Petr Beckmann http://groups.google.com/group/sci.p...776a56b861cd02 Newton's catastrophe is written in the language of geometry and most of it is found in a single page - http://gravitee.tripod.com/phaenomena.htm There is that much to discuss from a physicist's perspective that I hardly know where to begin and while the issue of using experimental analogies is not in doubt,if that community wishes to continue and be productive in astronomical affairs it must become familiar with the actual geometric arguments which produced planetary dynamics instead of following what is effectively a series of loose tales strung together and especially mentioning the motion of satellites around planets in the same breath as the motions of planets around the Sun. Behind the apparent civility of the Usenet back in 1992,the conceptual cracks were turning into canyons so despite the apparent descent of civility and participation on the forums,we are in better shape now as the whole thing has returned into a molten state with everything on the table.I have the insights of the astronomers on my side,not the phony magnification guys who play along with physicists, but genuine astronomical insights that were lost to Newton's strain of empiricism so while you discuss things within the confines of your indoctrination,a more substantial work is happening on a much wider stage. |

That thread was fascinating when I read through it - http://groups.google.com/group/sci.p...3995f62d7b4d26 The actual story which leads us to where we are now is truly an intellectual adventure,it doesn't set limitations but gets rid of the shortcuts which overreached into astronomical methods and insights. If you excuse me Sam,I am not an empiricist but can look at how these things are arranged to suit Newton's strain of empiricism so,unfortunately,it almost means having a one way discussion in the absence of any interested individual using terms that are both familiar to them but out of astronomical context.People don't have to read it or even make sense of it but I can see clearly where Newton was going even though empiricists once openly admitted that they couldn't work out how he arrived at his conclusions. The foundation of Newton's approach to planetary dynamics is relying on the fixed stars which is scalar in nature as it represents a celestial sphere and stellar circumpolar motion,because he uses or rather misuses the equatorial coordinate system in mapping the motions of celestial objects using this framework,these motions appear to come under vector analysis but as everything is moving in stellar circumpolar motion,this geometry infects vector analysis which is closer to the original astronomical methods and insights which used the motion of celestial objects such as the planets against the stellar background.I wish I could just say that dumping everything into stellar circumpolar motion or right ascension is the core problem,for that is exactly what happened,but the problem is more with human nature and the lack of accountability among empiricists as why bother changing when there is nobody around to object in a meaningful way. The idea is that the AU derived through 'sidereal time' reasoning offers a baseline for gauging variations in individual planetary orbits,Newton doesn't bother with such things as the main arguments for resolving retrogrades through orbital comparisons but acts like observations of the Earth are geocentric which are to be transformed by observations from the Sun as be heliocentric,he even goes so far as to equate the motions of the satellites around planets with planetary orbital dynamics - 'PHÆNOMENON V.' "Then the primary planets, by radii drawn to the earth, describe areas no wise proportional to the times; but that the areas which they describe by radii drawn to the sun are proportional to the times of description. For to the earth they appear sometimes direct, sometimes stationary, nay, and sometimes retrograde. But from the sun they are always seen direct.. " http://gravitee.tripod.com/phaenomena.htm Even in principle,it is better to sort through the problems and resolutions than stumble on pretending that experimental analogies apply willy nilly to all observations.The core issues are right there in that webpage and not in prefacing everything with 'empirical' which is common among those who wish to continue with Newton's toxic strain of empiricism,even Albert ended up doing that - http://books.google.ie/books?id=oiED...ge&q&f= false |

It was only later that Euler rephrased it as F = ma.. When you believe in 366 1/4 rotations of the Earth in an orbital cycle,you may say just about anything as it comes up against the known fact and experience that one 24 hour rotation corresponds to a day/ night cycle.The reason you are coming up with something as mindnumbingly bad as a complete disassociation between rotational cycles and one orbital cycle is due to the misuse of the equatorial coordinate system by dumping daily and orbital motions into right ascension. and that was the framework Isaac used to make it appear that there is such a thing as geocentric observations rendered into heliocentric modeling or absolute/relative space and motion as he called it. Your own system is being explained to you and one they once readily admitted they could not understand it - "The demonstrations throughout the book [Principia] are geometrical, but to readers of ordinary ability are rendered unnecessarily difficult by the absence of illustrations and explanations, and by the fact that no clue is given to the method by which Newton arrived at his results." Rouse Ball 1908 You can drop all the names you like since Newton's toxic strain of empiricism emerged but it still comes down to the fact that you cannot accept the proportion between 1461 rotations of the Earth to 4 orbital cycles or in its raw form of 365 1/4 rotations for 1 orbital circuit.Because daily and orbital motions can be separated the 1461 day/night cycles and 1461 X 24 hour rotations can be formatted into full rotations in blocks of 365 and 366 rotations allowing a 6 hour orbital drift omitted in non-leap years to be picked up by the 24 hour rotation and day/night cycle but as you imagine 366 1/4 rotations in an orbital cycle,you can't even comprehend any orbital characteristics which arise from 365 1/4 rotations per circuit. I have done everything to avoid condescension yet it comes back to accountability,the opportunity to bluff is fully subscribed to in the absence of actually knowing what Newton did to achieve the ends that you now follow.It is the lack of anger in coming to terms that Newton's agenda literally can't associate one rotation of the Earth with one day/night cycle and that is certainly an intellectual point beyond which it is not possible to go,the very fact that the empirical agenda before Newton was productive to a point and did not distort astronomical insights would normally give readers here hope that a resolution can be found but if it is there,I haven't seen it yet,not even a hint of it. * *Following Isaac Newton, who began his Principia with a definition * *of mass, and whose second law of motion, in Euler's formulation * *F = ma, defines the force F as the product of the mass m and the * *acceleration a (acceleration being, of course, a kinematical * *concept), the concept of mass, or more exactly the concept of * *inertial mass, is usually chosen. * *http://www.real-world-physics-proble...equations.html Sounds wonderful until I ask you does one 24 hour rotation correspond to a day/night cycle and you give the incorrect answer |

Gerald, 366.242199 rotations of the earth every astronomical year is not a matter of "belief" but an observable fact! Anybody can make the measurement. |
