Shame on physics and astronomy textbook writers for they failed miserably in explaining various different types of rotations, the solid body rotation in particular. I doubt a single physics or astronomy student after a 1 year course in the subject is able to talk about solid body rotation.
Now I have about 27 pages remaining before I stop writing New Physics and so I have plenty of space to start doing Solid Body Rotation in some detail.
Chapt15.47 detailed analysis of Solid Body Rotation and Solid Ring Rotation
Now, what I am going to do is give a picture analogy so even nonscientists can learn and participate. In science education we seldom try to teach a subject for all readers, but seem to be unable to step down the teaching so that all can learn and participate. For example, Feynman's Lectures on Physics was not really meant for classroom teaching but meant for a text for other physicists who already have a Phd in physics, and those three volume set should never have been a classroom textbook. In our classrooms, teachers are more often to err on being "over the heads of students" than to get it just right "on the same plane of learning so that the students can understand what is said."
In my books, in my writings, I always go for teaching everyone, even nonscientists, rather than the education system of the USA where they cater to only the scientist in training. And that is one of the reasons why physics is so backwards in theory and so filled up with fakeries rather than true physics.
So let me give a simple analogy model of a car racetrack and imagine it as big a track as Saturn's Ring. Where Saturn is, is a fan grand- stand of crowds of people watching. Now the Ring is circular tracks around the grand-stand and let us say there are 3 tracks to keep the picture simple. In the track 1 are 100 cars and all of them are going at the very same speed of 5 km/hour, and in track 2 which is further out there are 200 cars going at 5 km/hour, and in track 3 further out there are 300 cars going 5 km/hour.
Now let us analyze those three tracks, for in track 1 of 100 cars all going at 5km/hour, that they are evenly spaced and all having the same velocity so that they will not crash into one another. Same thing for track 2 with its 200 cars going all the same velocity of 5 km/hour.
Now in each track we can call that track a Solid Ring Rotation around the grand-stand or Saturn because the ring will stay there permanently since the cars are at the same speed and same distance apart from one another so they never crash into one another.
So that is Solid Ring Rotation, but what is Solid Body Rotation?
Well, if a person in the grand-stand were to picture a line drawn out intersecting the track 1 at a perpendicular and track 2 and track 3 at a perpendicular of the same line drawn out such that the same cars in track 1 line up with the same car in track 2 and track 3, would mean we have Solid Body Rotation, and not just Solid Ring Rotation. Now in order for there to be Solid Body Rotation, the speed or velocity in track 2 has to be very much larger than in track 1 of its 5 km/hour and likewise the speed in track 3 has to be larger so that when this person looks at that line, those cars in track 1, 2, 3 are all keeping up with the line.
Alright, now, so we have a distinction between Solid Ring Rotation and Solid Body Rotation. Now we ask, in the Rings of Saturn, are those ice crystals of the Ring, are they only Solid Ring Rotation, or are they Solid Body Rotation?
And also, in barred spiral galaxies, we already have an answer as to whether they display Solid Ring Rotation or Solid Body Rotation. Because they have a Bar in their Barred Spiral Galaxy, means they are Solid Body Rotation.
Now we ask whether there is some distinctive feature of Saturn's Rings so that we can claim it is more than Solid Ring Rotation or whether it is Solid Body Rotation? Well, if we can pick out several larger entities within the Rings we could use that as a "line or bar line" to determine if Saturn's Ring is Solid Body Rotation.
However, we can determine that the Red Spot of Jupiter and most of the sunspots or flares of the Sun are Solid Body Rotation because the entire feature stays in tact over numerous rotations. If they were just Solid Ring Rotations, the Red Spot of Jupiter or the flares and sunspots of the sun would not have survived as long as they did. The Red Spot has been on Jupiter since Galileo saw it some hundreds of years ago.
Google's (and Bing's) searches and archives are top-heavy in hate-spew generated by search-engine-bombing. And the Google archive stopped functioning properly by about May 2012 to accomodate Google's New- Newsgroups. And recently Niuz.biz (Docendi.org) threatens to harm your computer if opening a post of mine.
The solution to the sci. newsgroups is to have the sciences hosted by colleges and universities such as Drexel University doing sci.math, not by corporations like Google out to make money. Science belongs in education, not in money motivated corporations. Do I hear a?University doing sci.physics, sci.chem, sci.biology, sci.geology, etc ?etc
Only Drexel's Math Forum has done a excellent, simple and fair archiving of AP posts for the past 15 years as seen here:
