Iwonderaboutthings Posted July 13, 2014 Author Share Posted July 13, 2014 (edited) The quality of the force might be the same, but not its magnitude. Hence you find different values for the acceleration constant on different orbital bodies. quality? and magnitude? This strikes some curiosity.. What is quality? Magnitude When I think of magnitude, it reminds me of pointing vectors, manifolds, space time, relativity, the quantum subjects... Is that correct? By the way, this explains why a canonball falls as fast as a pea (ignoring air resistance): the force on the canonball is greater, but it takes exactly that much more force to accelerate it the same as the pea. Mass energy equivalence I think... I never knew all this,, thanks, I guess now it makes sense. What Strange said F = G [m1]*[m2]/r^2 assume [m1] is your object so via F=[m1]a we can state [m1]a = G [m1]*[m2]/r^2 and after dividing by [m1] on both sides... a = G*[m2]/r^2 'g' causes way too much confusion for a lowly acceleration. 'g'. I've found it just confuses people. It certainly does with me.. Edited July 13, 2014 by Iwonderaboutthings Link to comment Share on other sites More sharing options...

Sensei Posted July 14, 2014 Share Posted July 14, 2014 (edited) venus = g 7.5 m/s/s Venus a = 8.87 m/s^{2} mars = g 12.7 m/s/s Mars has a = 3.69 m/s², or a=3.711 m/s² according to Wikipedia.. Is it wrong to question: Who or what calculated 9.8 m /s /s on earth in the first place.. In other words if you can calculate the force of acceleration on other worlds, and have different values. Where did 9.8 m /s/s come from?? How can you even ask such question after reading post #34??? http://www.scienceforums.net/topic/84336-if-pi-ratio-was-squared-and-98-mss-how-would-this-change-the-whole-of-science/?p=815752 Edited July 14, 2014 by Sensei Link to comment Share on other sites More sharing options...

But this now makes no more sense now in relation to speeds faster than c, and how " now " the speed of light is involved as a frequency in that computer animation. Why? Because pi ratio is used a lot in general relativity and other quantum formulas, " IN SIDE" the quantum world... This is not fair! But it makes you think,,, after that post, I have been thinking a-lot about computer simulations. Don't forget about fps,frames per seconds and formats like in 3d animations. Its assumed as visual perception only. Don't forget, an animation can have many other elements within it moving faster than 30 frames per second as well. How would post #34, or that link, account for the discrepancies? That may have not sounded right, I don't normally hear people talking about this.. In other words, if I took a movie of a falling object, then placed it in OpenOffice , but it had objects in it, like " a butterfly flying" in the back ground" or a fly passing by, " yes I know "wait" , or all of a sudden a rock fell through my sealing.. Within the domain of the entire "animation" and all "random objects" moving at different speeds but still at a perceived 30 frames per second. -------->would 9.8 m/s/s still be a valid case for the entire animation and all the "elements in it moving??" I think I would have to scroll back and fourth within the domain of the animation's length, time, and period, in order to derive anything " useful out of it." This is why I am trying to mix frequencies and time, from what I know, I shouldn't. why?????????? Its weird! Its like 9.8 m/s/s " KNOWS" where the bottom of the camera's lens is. Or better yet, it appears g is basically a flat hyper space = 0 A flat reality... Minkowski spac http://en.wikipedia.org/wiki/Minkowski_space I am not a believer in this by the way... I don't read anything about this, I don't know how to explain it any other ways.. However, here is something to consider... They did not have computers back in the days of Issac Newton, nor did they have the space shuttle to test his formula..We just used them and call it a day... I should learn Séances, so I can ask Newton personally! Michio Kaku: What If Einstein Is Wrong? This video concerns this:: Within the domain of the entire "animation" and all "random objects" moving at different speeds but still at a perceived 30 frames per second. would 9.8 still be a valid case??

Sensei Posted July 14, 2014 Share Posted July 14, 2014 (edited) In Newtons time they were interested in predicting position of some planet in advance. If prediction was correct model was correct (more or less precise). It's similar to mine example from #34 post, but instead of observation of failing body at hand, record location of Venus through whole year, record location of Mars whole year, record location of Moon whole year.. Analyze their positions, to get velocity, analyze how they change in time. And basing on previous values, predict where body will be in future.

This is not fair! I'm not sure why your having a problem with pi, its simply the ratio of a circles circumference to its diameter. Take a wheel or any circular object and a ruler. for simplicity sake use a 1 inch diameter object. draw a line on one edge of that object. place that line on a ruler, roll the wheel along the ruler until the line once again returns to its original point. the distance of travel will be approximately 3.14 inches. now as a lab experiment gather various circular objects 1,2,3,4,5,6,7,8,9,10 inch diameters conduct the same steps as above, divide the distance of travel by the objects diameter, you will get the same result of pi pi is used throughout any formulas that involve a circular or semi circular object or interaction. such examples are waveforms, frequencies, orbits, etc. Its fundamental in measuring the distance relations of those frequencies, waveforms and orbits. Much of physics is geometric relations of interactions, as such pi is used extensively as its used in trigonometry. Differential geometry is an extensive subject involved in physics. I would advise spending some time studying trigonometry and differential geometry, it will greatly aid you in understanding many of the physics formulas you will come across. For example it will also help to understand how Pythagoras theorem is used in numerous formulas. here is one example of its usage in the FLRW metric http://cosmology101.wikidot.com/geometry-flrw-metric/ whether its fair or not is irrelevant, it works for the geometric applications that it is describing simple as that this article will also help with how Newton came up with the universal laws of gravity and the gravitational constant http://qinf.fisica.unimi.it/~paris/FisBio/m101.pdf there is naturally better articles however this one shows the steps in how Newton developed his theory here is a site with a good animation of pi at work with waveforms, also correlates sine, cos and tan functions to the waveform as well http://www.mathsisfun.com/algebra/trigonometry.html http://www.mathsisfun.com/algebra/trig-sin-cos-tan-graphs.html graph plots of sine, cos and tan this site I find handy as it includes various calculators and plotter programs, not the greatest to learn from but it will help check your work so to speak http://www.intmath.com/help/interactive-math-applications.php for actual learning I would work from its home page http://www.intmath.com/ Edited July 14, 2014 by Mordred 1 Link to comment Share on other sites More sharing options...

I am confusing now what is constant, not sure if it is the speed of light or varying accelerations on other planets, the whole thing looks to be unclear. What "now " is driving all galaxies away from each other? Is it the same force? "NOW" They say the Universe is Flat???? WHAT?????? A new study confirms that the cosmological constant is the best fit for dark energy, and offers the most precise and accurate estimate yet of its value, researchers said. The finding comes from a measurement of the universe's geometry that suggests our universe is flat, rather than spherical or curved. Link: Einstein's 'Biggest Blunder' Turns Out to Be Right http://www.space.com/9593-einstein-biggest-blunder-turns.html I think I need to hear that " here" universe is flat---------> yes? no? But pi ratio can be used as volume---------> yes? no? I'm sorry to ask this and excuse me for saying, but I cannot help it.. Is the internet a good place to read about science? or is this all propaganda, and marketing scheme? For instance all that Maya 2012, " nonsense " really had people scared for their lives... I really wish, someone would stop this nonsense, and start placing articles that are 100% true.. It confuses people whom want to learn and waste the time of professionals having to re-explain things over and over again, in turn they become frustrated, its true. I get the feeling this is "ALL A BIG JOKE " and feel super awful and sad about that. Thats just my opinion... What do you mean by "inverse of a path"? I think the meaning, or what I should have said was this: mass and energy (two sides of the same coin) bend space-time with their gravitational force. Link: http://www.space.com/9593-einstein-biggest-blunder-turns.html' Einstein's 'Biggest Blunder' Turns Out to Be Right But that link, kinda got me sick to my stomach, flat universe?

Strange Posted July 14, 2014 Share Posted July 14, 2014 I am confusing now what is constant, not sure if it is the speed of light or varying accelerations on other planets, the whole thing looks to be unclear. The speed of light is constant. Acceleration due to gravity on other planets is different from on Earth (i.e. not constant). What "now " is driving all galaxies away from each other? Is it the same force? It is not a force. It is just the expansion of space (i.e. the distance between things). I think I need to hear that " here" universe is flat---------> yes? no? It certainly appears to be. But pi ratio can be used as volume---------> yes? no? No, it can't be used as volume. It is just a number. Although it is used in the calculation of the volume of a cylinder or a sphere (because they are round). Just a note: each of your statements so far appear to have no logical connection whatsoever. You seem to making completely random statements. I don't know why. Is the internet a good place to read about science? It can be. There are some very good resources.

Mordred Posted July 15, 2014 Share Posted July 15, 2014 (edited) no flat universe is an energy-density relation, a flat universe would have a total energy density that = the critical density critical density is a calculated value that the universe would stop expanding and start to collapse. (a perfectly critical dense universe the curvature would be perfectly flat for more info read) http://cosmology101.wikidot.com/universe-geometry page 2 http://cosmology101.wikidot.com/geometry-flrw-metric/ this is not the same as dimensionally flat, its flat in terms of energy density relations only. The main thing to realize is often a geometric relation applies only to the interactions being described. GR spacetime is a good example of this, its the relation of how gravity influences matter. In both these cases it applies only to the mathematical model of influences being described. One of the most common misunderstandings is people tend to think that space has a substance that can be warped, grows, stretches etc. They do not realize that GR is a geometric descriptive of gravity influences on matter, and only applies to the relations of how gravity interacts with matter. Space itself has no substance its simply volume filled with the energy-mass contents of the universe.

Good food for thought. can easily vanish?.............Umm, ok, where does it go?? This is not fair, science does not believe in magic... where does it go?? I hear that light also takes the shortest path to travel, something I heard in Snell's Law: Snell’s law and light traveling along the shortest path http://web.cs.du.edu/~carlara/thesis/CarlosLaraThesis.pdf I just read some articles on the ecliptic plane and celestial planes of planets, and cannot help to ask, if pi ratio describes I guess a perfect circle, then how does the " warping of space and time" apply to the use of pi ratios as per cosmology is concerned? Meaning that not all things are perfect circles, this is why I wonder if pi ratio is merely " time" independent, because it's used as a perfect circle and a precise way in describing time inside cycles. Now as per the meter is concerned......Nature, from what I know is not a perfect circle but is time dependent ? Michio Kaku said that neutrinos traveled faster then c by 60 seconds, or something to that nature, looking at it now, is that the same as 1 second of arc? Or 1 frequency? They did use GPS for the reading, he stated this as well. He did say twice the problem is circular.

Strange Posted July 16, 2014 Share Posted July 16, 2014 (edited) Michio Kaku said that neutrinos traveled faster then c by 60 seconds, There was an experiment that appeared to show this (it was very famous at the time). Eventually they tracked down the error - a faulty cable connecting one of the instruments, I think. The final result was that the neutrinos travel at so close to the speed of light, we can't really tell the difference. (And it wasn't 60 seconds, it was 60 billionths of a second over a distance of about 700 km.) can easily vanish?.............Umm, ok, where does it go?? If you measure g in feet/s/s then there is no connection to the value of pi (the connection has "vanished" or was never there). How can you divide chickens and socks and get a meaningful answer? You can't. And even though chicken and socks was a joke, this is a very important point. One way of checking equations in science is to do "dimensional analysis" - check that the metres, seconds, chickens, etc on one side of the equation are the same on one side of the equation as the other. That is why one of the answers to your initial question was: pi has no units, so it cannot square to a something with units. As such I don't know how to answer your questions scientifically. You were trying to convert between something with no units and something with metres and seconds. This is like trying to convert between chickens and socks: meaningless. I just read some articles on the ecliptic plane and celestial planes of planets, and cannot help to ask, if pi ratio describes I guess a perfect circle, then how does the " warping of space and time" apply to the use of pi ratios as per cosmology is concerned? Pi does not just apply to perfect circles. For example, the equations for an ellipse also involve pi. But you are right, in curved space, the ratio of diameter to circumference is no longer pi. If you draw a circle on the surface of a ball and measure the circumference and diameter, you will find they are not in the ratio pi. In fact, the ratio changes depending on the size of the circle. For a small circle, the value will be close to pi. For the largest circle, it will be 2 (I think). But I bet the formula connecting the size of the circle and this ratio ... involves pi!

Iwonderaboutthings Posted July 18, 2014 Author Share Posted July 18, 2014 (edited) just a side note here is the procedure to calculate a planets mass lets say you just spotted a new planet and would like its basic characteristics http://www4.wittenberg.edu/sgmoa/supplemental/FindExtrasolarPlanetMass.pdf http://www.sfu.ca/colloquium/PDC_Top/astrobiology/discovering-exoplanets/calculating-exoplanet-properties.html In your link here: http://www.sfu.ca/colloquium/PDC_Top/astrobiology/discovering-exoplanets/calculating-exoplanet-properties.html I see Kepler's Third Law law uses pi ratio squared, " looks like I am several centuries too late on this" however, I noticed something peculiar here: Copied and pasted information: As an example, since the Sun is about three hundred thousand times heavier than the Earth, ignoring the mass of the Earth in this calculation would introduce an error of less than 0.001%. The equation can be solved for the only remaining variable which is the orbital radius, 'a'. Or 'a' = x^2 = -1????? Um....Isn't 0.001 used as a frequency? This really now complicates things does it? I never even knew this " really " I did not, thanks for the link! Now, pi ratio " obviously squared " = close to 9.8 m/s/s, would this be referencing earth as the center of the Universe?? It looks like so... Think about it in relation to time. I know I am not the only one whom has thought of the correlation, however I am more intrigued with the statements: As an example, since the Sun is about three hundred thousand times heavier than the Earth, ignoring the mass of the Earth in this calculation would introduce an error of less than 0.001%. The equation can be solved for the only remaining variable which is the orbital radius, 'a'. Or 'a' = x^2 = -1????? Earth is measured in kilograms right? So how could " any metric" system describe "energy" within: 10^3 = kilo = Distance and grams= milla = Time?? GOSH! That is very small! Here is a link on this: Black Holes and Sub-millimeter Dimension http://arxiv.org/abs/hep-th/9808138 We are still in space here so this inquiry should still be a valid case here. So then, wouldn't the " kilogram" have two separate systems of measure that make them both inversely proportional not to the square of the distance but to ----------------------> time! as in E=mc^2??????????? I get this logic from: As an example, since the Sun is about three hundred thousand times heavier than the Earth, ignoring the mass of the Earth in this calculation would introduce an error of less than ------> THERE--------->0.001%. The equation can be solved for the only remaining variable which is the orbital radius, 'a'. Or 'a' = x^2 = -1????? Again shouldn't that be saying this: The equation can be solved for the only remaining variable which is the orbital radius as x^2 = -1????? About 10^3 = kilo = Distance and grams= milla = Time. 1 micron = 1 000 nanometers 1 μm = 1 000 nm TT?1 micron = 1 micrometer 1 μm = 1 μm TT?1 micron = 0.001 millimeter 1 μm = 0.001 mm Link for these units is here: http://www.aqua-calc.com/what-is/length/micron a^3 is only obvious here as volume, acceleration, and time rather the speed of light squared as mass and energy equivalence.. Now wonder space is flat, not necessarily outer space but both spaces inversely..This radius must then describe the straight path of a -1 complex number relation in QM subjects. All exponent "then" are merely arc minutes*.5 = +1. I guess their is more to a static universe than we know ??? I think pi ratio does have units but not units we " recognize" as a metric but maybe static units, or something ......

The equation can be solved for the only remaining variable which is the orbital radius, 'a'. Or 'a' = x^2 = -1????? a is the length of the semi major axis (orbital radius). you need to calculate for "a" depending on the orbital period. (orbital period is the time it takes for an orbiting body to complete of full orbit. the error is the accuracy of the model method. this has no relation with the rest of your post. a better formula relating orbital period, (time) semi major axis and bodies gravity is covered here. (due to the extreme difference in the suns mass and the Earths mass the center of gravity is the Sun itself in Kepler's laws so the sun is stationary) http://en.wikipedia.org/wiki/Elliptical_orbit keep in mind orbiting bodies are elliptical which is where it vis-visa equation comes into play (also on that page). here is what the semi-major axis means http://en.wikipedia.org/wiki/Semi-major_axis "In geometry, the major axis of an ellipse is the longest diameter: a line (line segment) that runs through the center and both foci, with ends at the widest points of the shape" for an ellipse you have two axis the semi-major axis and the semi minor axis. a is the semi major axis b is the semi minor axis Earth is measured in kilograms right?
