about newtons gravitation theory
A person from yawatmal(maharshtra/India) has claimed that wt. of body
do not depend on graviattion but the density of space. He expalined on experiment in which he had kept one one kg material supended to spring balance. and this is kept in one bottle and that bottle is kept in pther bottele. He claims that on heating density of material changes so spring balance shows different wt. than previous. .Is it possible if so How? |

Many experiments have shown inertial mass to be equal to gravitatonal mass. |

But I doubt very much that's the explanation for what he observed. In fact, gravity has been measured with exquisitely sensitive scales- the sort of thing that you don't just build in your garage), and nobody has seen a dependence on density. Our understanding of gravity has been tested far beyond what a "spring balance" can resolve. Assuming this guy isn't just a nut, and that he actually attempted a serious experiment, it's far more likely that the method he used to heat his sample affected the balance. A typical spring balance will show more variation in its measurement from a temperature shift of a few millidegrees than it will from gravitational effects. There are many other systematic errors in this type of experiment that are orders of magnitude larger than the effect being measured. Our ability to measure mass has become so good that labs need to compensate for lunar and solar tidal effects and gravitational noise from mass motion in the Earth's interior. It seems really unlikely that the experimenter in question took these things into account (or that his scale was even sensitive enough for them to matter). _________________________________________________ Chris L Peterson Cloudbait Observatoryhttp://www.cloudbait.com Care to explain how the viscous composition of the Earth is moving. Didn't think so !. The Earth's interior is not exempt from generalised rules governing the rotation of a viscous composition,basically the Earth' interior below the fractured crust does not rotate as a single unit but displays the traits of differential rotation.I know this by way of the Mid-Atlantic ridge and the generation of crust off that ridge - http://www.dkimages.com/discover/pre...2/60018786.JPG The energy required to cause the 40 km deviation from a perfect sphere also drives the motion of the relatively thin surface crust and were dynamicists not tied to Isaac's coat tails,we would be discussing elements of rotational dynamics effects on crustal dynamics such as the motion of the fractured crust across the less than perfectly spherical planet and its geological consequences. As for Isaac,he built his terrestrial ballistics agenda on an astrological framework,in short,his agenda never worked unless you consider fitting the orbital motion of the Earth into the calendar system to be some sort of achievement.Time to grow up guys !. |

The energy required to cause the 40 km deviation from a perfect sphere also drives the motion of the relatively thin surface crust No energy is required to cause a spinning Earth to continue to spin. It is the fact that the Earth is spinning that creates an (apparent) force contrary to gravitation that is strongest at the Equator. Thus, no energy expenditure is involved in maintaining the oblateness of the Earth. But the Earth's surface is of cool, solid rock. Yet, we have volcanoes. So it is hotter inside the Earth than at the surface. So, underground, where the rock is still liquid, the part of it closes to the cool surface cools off... and then, being denser, it falls down, while hotter magma rises. This means convection currents, like we see every day around us, and *that* is where the energy for continental drift comes from. We follow Newton because he is right; calculations done according to Newton correspond to the things that actually happen. John Savard |

Of course, his position here (like most everywhere) represents, shall we say, a _minority_ opinion. A minority of one in point of fact,however,the precise rotational details of what causes the Earth to deviate from a perfect sphere are already there via stellar dynamics and the correlation between maximum Equatorial speed,differential rotation and spherical deviation.To put this another way,it is almost impossible to resolve the 40 km planetary deviation without apply differential rotation to the moving viscous composition and thereby replacing the stationary Earth pseudo- dynamic of 'convection cells' (which requires no reference to planetary shape or motion). I do not accuse anyone of missing points,there are multiple ones in this thread ,for instance, it shows that dynamicists are excellent at isolating processes while being oblivious to physical considerations of structural and timekeeping astronomy.This is an inherited thing from the 17th century when they organised the experiment-fest known as the Royal Society using Newton's treatise as a platform for introducing the lab into the celestial arena,it sounds great until it is demonstrated the price of tampering with known astronomical principles to suit conclusions such as terrestrial ballistics and planetary motion or the sidereal time justification for the motions of the Earth. I have nothing to gain by unduly criticising dynamicists who can actually apply generalised rules for rotating viscous compositions to the Earth's interior via fluid dynamics however the entire community seems to be engaged in some silly attempt to create a 'trekkie' environment where matters of faith are treated like ignorance and superstition,in fact,that ideology may now constitute a religion on its own.Again,I am a Christian astronomer who is deeply involved in the Western astronomical tradition which means that in astronomical matters I am dragged back into discussing matters of faith in order to counter those who oppose the intuitive intelligence required to appreciate both Christ/Christianity and astronomical methods and insights.In short,if you are anti-religious or approach matters of faith at the lowest level (such as literal interpretation of Genesis),you are unlikely to be capable of appreciating the intricate web which is structural astronomy,again,St Augustine concisely states the obvious - "If anyone shall set the authority of Holy Writ against clear and manifest reason, he who does this knows not what he has undertaken; for he opposes to the truth not the meaning of the Bible, which is beyond his comprehension, but rather his own interpretation, not what is in the Bible, but what he has found in himself and imagines to be there." Augustine This is the most balanced view that I know of and if genuine people wish to extract themselves from this quagmire of science vs religion then they can at least see that our ancestors were not fools when the need to keep Spiritual and other matters aside for practical purposes. But regardless of what mechanism he wants to hold responsible for the motions in the Earth's interior, the only thing relevant to my points was that motion is taking place, and it produces noise in the gravitational field that we actually have the capability to detect with our instrumentation. Right now Chris,there are many people curious as to know whether our dramatically changing climate is due to human influences or if there is some natural mechanism involved,they do not want to know about 'gravitational fields ,inertial masses or all the other vocabulary surrounding astronomy at the moment,they simply want a clear response from responsible people and perhaps some day they will have it. I am absolutely bewildered at the response to the imaging taken of Uranus which would ease the interpretation of the orbital component as separate to diurnal rotation,not because the older explanation for seasonal variations is unsatisfactory but more than the orbital component is fascinating in its own right.Although I am hesitant to graft this motion immediately into the problem of climate change,it exposes a definite and clear answer to the question of whether climate change is due to human or natural mechanisms.The answer is an important statement - if it is not possible to assign the correct relationship to daily rotational and orbital motions,their relationship and their seasonal effects,it is incontrovertible that more complicated issues like long term climate will suffer the same fate. _________________________________________________ Chris L Peterson Cloudbait Observatoryhttp://www.cloudbait.com |

I would not even want to hear how thermal convection cells mesh in with the paleomagnetic data yet the entire interior of the Earth's composition and motion is designed around that pseudo-dynamic.The telescopic instruments already pick up differential rotation in stars,there are probably instruments picking up differential rotation of the viscous interior of the Earth but misinterpret it as differential rotation between 'cores'. I don't get this,with stellar dynamicists already working with variations in stellar shape due to different maximum Equatorial speeds and with differential rotation as a given,how are they managing to ignore that 40 km giant clue in respect to the fluid dynamics of the Earth's interior.It may not be much to go on but that maximum Equatorial speed along with the 40 km deviation must surely appeal as a tantalising clue as to the composition and motion of the interior. I am not a dynamicist,I am an astronomer who takes physical considerations into account that dynamicists do not have to or do not want to yet even I can see the possibilities of apply rotational geodynamics to crustal dynamics and evolution.I do not have the restraints of self-moderation that you guys impose on yourselves but what is the point if you cannot even discuss basic rotational consequences short of denying that they exist and especially geological and climatological consequences ?. |
