[Vo]:One advantage of Schauberger Doppledrall is that it turns Coriolis stress direction
Hi I found an advantage of Schauberger Doppeldrall - double whirl in English. The idea is that Taylor-Dean vortex creation is prevented by letting the Coriolis stress, that causes the buildup of Taylor-Dean vortices, act in different directions instead of consistently the same direction as is the case in unturned flow. Taylor-Dean vortices are the same as Görtler vortices. They are described in the plane perpendicular to the flow. A more general description is the Coriolis stress caused in bent flows. Dean vortices are mentioned as a lossy type of turbulence or drag in pipes and are mentioned in incompressible flow like water in pipes. Görtler vortices are usually mentioned in air with constraints like a plane wing.

[Vo]:Betz's law and circulation/vorticity
Hi Can someone help me calculate the circulation (or vorticity, ∇×v ) in flows where Betz's law is used? I think I know a way. It would be interesting to see if others find a way. My way involves the following reasoning. Betz's law determines the power taken from the flow and brought into the turbine. This is equal to a force on the turbine equal to F = P / v. Another way to determine the force on the turbine is to use the Kutta–Joukowski theorem. Do these two methods give the same result? Maybe some other meaningful relation can be found by setting the force from the two methods equal. David
[Vo]:Direct flow acceleration
Imagine a flying object, maybe a sphere or cylinder for simplicity, the gas flowing around the object has to flow around it, the gas is forced to move around the object. Such forces need to have a pressure gradient force ( volumetric force = ∇ pressure) , and the pressure change corresponds to a temperature change with an adiabatic relation. Imagine the flying object at two different speeds, v and v + Δv, close to each other. Determine the difference in the temperature field in the surrounding gas between the two situations. My question is: If I artificially apply such a temperature field around an object would it accelerate? (Would the object go from speed v to v + Δv ? ) David

[Vo]:3*20 bit cameras wanted
Hi The camera market is strange and weird. They sell 13 megapixel cameras althoug very few can view more than 2 megapixel and commonly we view far less. What DOES however improve quality is increasing bits per color from 8 to 16 or more. 8 bit is just a bad heritage from a time when memory was expensive and performance slow. So why aren't there any 16 bit cameras available? I found one for $1500. The full dynamic range of the eye is 1:100 which requres encoding of 20 bits per color or 60 bits per pixel, and the static range is 1:1 representable with 14 or 42 bits. Such pixels would be a much better choise compared top increasing the megapixel to absurd levels. With 60 bit colors the true intensity of the light would be recorded in the image. Further increase of features would be an alpha channel for transparency. This cahnnel should not be 8 bit. It should be 60 bits as well because transparency can be different at different colors. One 20 bit alpha-channel per color makes a 60 bit alpha channel. Together with the original color thats 120 bits per pixel. Monitors aren't much better. I just search and only found two monitors with 12 bits per color as maxiumum resolution David

[Vo]:Linear motion Sagnac accelerometer
A linear Sagnac interferometer works in regard to producing fringe shifts when accelerated. This can easily be understood by considering the Doppler effect and the retardation that the light does along the linear path of the light. The Doppler effects do not cancel out since there is a delay in mixing source and destination signals. Redo the experiments with light frequency changing over time, for example as a ramp function, to get an effect on speed and not only acceleration. If there is a linear Sagnac effect even in this case the beat frequency would differ at different speeds. Do this experiment on a rotating frame as well. The common understanding is that the rotating frame would be affected by speed and the linear interferometer would not. Agree? Mail this suggestion to Wang if you have his address.

David David Jonsson, Sweden, phone callto:+46703000370 Simply put when torsion is extreme enough, the vectors of normally perpendicular forces such as electricity and magnetism may become almost parallel;they undergo a kind of distant parallelism brought about by such extreme warping of space. Depending upon the amount of torsion, those vectors may not necessarily be perpendicular any more, but deviate slightly or greatly from such perpendicularity. pg 34/ Top Secret Torsion/Secrets of the Unified Field/ Joseph Farrell http://www.flickr.com/photos/harvich/4138926072/ 2009 Flux Capacitor Model E X B embodiments on separately phased resonances The Flux Capacitor is a spatially interacted electrical resonance. Resonance is the balancing of magnetic and electrical fields to contain equal field energies, where expression of this energy uses a coil for the magnetic flux, and a capacitor for the electric field energy. Normally these two different field energies exist in separate space, and because they oscillate they also exist in separate timings, whereby when one field is full the other is empty. The first premise of the flux capacitor is to Tconstruct a device whereby the vessels containing each energy expression themselves can exist in the same space at right angles, thereby creating a third reaction force to be obtained in the remaining third angle in space, here to be obtained by non-magnetic stainless steel rods protruding from the water capacitor. The aim here is to split the water molecule into oxygen and hydrogen fuel with the minimal amount of energy. Two 90 degree phased flux caps can share timings of field energy which is the goal of these endeavors, where the magnetic field from one resonance can be spatially interacted with a concurrent electric field from another separately phased resonance. http://www.flickr.com/photos/harvich/4138199465/ Axially Insulated Water Capacity in 465 hz Resonance This shows the effect of just the electric field resonating from the right coil at 2700 volts on a hand held grounded neon bulb. Notice that the end connection of the neon need not touch the central electrode of the water capacitor; the electric field energy passes through space itself. The input voltage is obtained from a mere 7 volts obtained from an AC car alternator rotating at a constant rpm to output 465 hz. To achieve the higher voltage output shown here a first stage of resonance is employed which multiplies the initial voltage 15 fold. These comprise two 500 ft wire spools of 14 gauge wire stacked in series; ~ 23 mh@2.6 ohms using 5 uf for 465 hz resonance. This first stage of series resonant rise is necessary to achieve any appreciable amperage through the secondary (interphasal) resonance to be formed into a flux capacitor principle, whereby this then increases the voltage almost another 17 fold. Each of the ending flux capacitor components are 180,000 ohms impedance at this frequency. The coils contain almost 8 miles of 23 gauge wire. An AC alternator is used to obtain the needed higher frequency to enable the resonances to spatially exist inside each other, which then involves special circumstances. Since every changing electric field also appears out of phase as a changing magnetic field according to the derivative of the electric field's rate of change in time, induced currents can be measured when a second coil is employed to surround the axial capacity employed as the first resonance to be engaged, which is shown here without the addition of the second resonance in the three phase triangle. It is found that the induced currents due to induction via spatially enclosed capacity inserted into the coils interior volume: that this value comprises 2/3 the amount of current registered when the interphasing is given its actual separately phased line connections. The second resonance uses an ordinary spatially separate plate plexiglass capacity. Essentially this second large coil in the 60 Henry range @ 840 ohms can be preliminarily tuned to the spatial influence of the initial resonance; however during this tuning where L2C2 has its capacity varied as a shorted loop formation, an amperage meter can be enclosed in this loop to find the point

[Vo]:The efficiency of the Silex isotope separation method
Hi Assume you could get absorption of a laser photon in unranium hexaflouride based on uranium 235 and not in 238. I can not imagine what I read in newspapers since the optical excitation would be almost the same. Rotational and vibrational spectrum however would differ by approximately 1% or less. Even if an optical absorption can have an effect at say 2 µm according to http://jcp.aip.org/resource/1/jcpsa6/v16/i5/p442_s1?isAuthorized=no Makes the speed difference for one photon absorption to become v = 2hf/mc = 2h/m/lambda = 0.0011 m/s which is somewhat more realistic.

Re: [Vo]:Physics depends on choice of coordinates
Hi The Madelung constant is vital for our existence. At least some crystalline matter can not exist if it is divergent. The Madelung constants, there are different ones for different crystals, have by experiment and common experience a finite value. This means that our reality is cubic and not spherical. Any mention of physics being coordinate invariant is thus falsified. Coordinate invariance is just an assumption that some physicists have made based on ideals instead of real experiences. The math behind this is not hard to grasp. Imagine having to divergent series. One is diverging towards positive infinity and the other towards negative infinity. If you add those two together they can become convergent depending on in which order the additions are being made. On the other hand it is imaginable that spherical mass distributions have divergent Madelung constants meaning that their atoms have a diverging electric potential, and that cubic distributions have finite electric potentials for their atoms. I think it would be very interesting to have a convergent Madelung constant for a crystal and then change something so that it becomes divergent. Extreme potentials would then appear in the matter and maybe progress above what is needed for fusion or fission. One thing that strikes me is that Plutonium has a lot of different possible crystalline states. Maybe this is connected with it being radioactive? I ask for an investigation regarding a connection between nuclear activity and Madelung divergence. Why have we been told that electric potentials in matter are too weak to cause nuclear reactions when the Madelung series summation can give a totally different result? I have seen reports being mentioned where it says that the shape of an object can affect the rate at which a radioactive material is decaying. One could assume that spherical mass distributions radiate more than cubic masses. On the other hand I haven't examined at what rate the Madelung constant diverges. If it is diverging at sizes of a black hole then truly it is describing reality. Could someone investigate this further? I just need an argument against anything that is referring to coordinate invariance. I do think alternatives to coordinate invariant theories should and even must be examined. Solvability of equations is sometimes also dependent on coordinate choice. The advance of physical science is said to have originated from changing to an origo at the Sun instead of Earth, and currently there is a problem of having it in a galactic centre. At a more philosophical level there is also support for that the way of viewing gives different experiences.

Second column is the timestamp in seconds since 1970 with microsecond precision. I am trying to keep it at 2 seconds. When the ntp correction is done there can be a big timestep like this 33057 : 1324332734.041153 : 6850633 33058 : 1324332818.342256 : 6850938 Third column is the ticks in the geiger tube. Typically 200 per second. Sometimes the rechargeable battery runs out in the counter and then the counts drop. Sometimes data is missing but counts have to be accumulated over several minutes anyway to get statistical precision so this is not a problem. The counter is 32 bit unsigned and will return to zero after 4 billion something. This is close to 8 months.

[Vo]:Regarding the Michelson-Morley experiment and similar
Hi The Michelson-Morley experiment and similar linear interferometers are actually rotating when they are in use. They are thus similar to Sagnac-interferometers. A rotating Michelson-Morley interferometer looks like in the attached picture. [image: image.png] The black interferometer in this picture rotates and thus has different positions at different times. The light-ray however is moving along a straight line and hits the end of the interferometer at time t0+dt and is reflected back at the origin at t0+2dt. As is seen in the picture the light is moving a somewhat shorter distance than the length of the interferometer. The path length of the light ray can be easily calculated. With angular velocity omega and length L of the interferometer and speed of light c the light ray path l becomes l = L*cos(omega*L/(2*c)) or relative to the interferometer length l/L = cos(omega*L/(2*c)) = sqrt(1-sin(omega*L/(2*c))^2) which for small angles approximates to sqrt(1-(omega*L/(2*c))^2) Compare this with the Lorentz-contraction L/L0 = sqrt(1-v^2/c^2) The expresions are definitely similar. They imply that v = omega*L/2. For an 11 meter long interferometer, the length that Michelson and Morley used in later experiments, v becomes 7.3 *10^-5 *11/2 = 4 * 10^-4 m/s which is a very low speed. Much lower than is detectable with such an interferometer. http://en.wikipedia.org/wiki/Michelson%E2%80%93Morley_experiment#Early_experimentsThe null result of the Michelson-Morley-interferometer is explained by Lorentz contraction: http://en.wikipedia.org/wiki/Michelson%E2%80%93Morley_experiment#Length_contraction So, would you say that the interferometer is shortened as special relativity says or that the light rays are shortened as shown above?

The geometry of this is shown in Fig.1, in OPERA.jpg, attached. Point C is CERN, the neutrino origin. Point S is San Sasso at the time of neutrino departure. Since San Sasso is east of CERN, the earth rotates away, eastward, from CERN during the time of flight of the neutrino. This makes the distance *longer* than would be estimated by distance between geodetic coordinates. The neutrino arrives at the new San Sasso location S', which is eastward from S by distance d. Only the neutrinos initially aimed at point S' arrive there. Assume the distance C to S is 730 km stated in the Adam et al. OPERA article. Assume point B to be 730 km from point C on the line from C to S'. The neutrino thus has to travel the additional distance x from B to S' due to the eastward motion of the earth during its time of flight. Let point A be the point due south of CERN and due wet of San Sasso, i.e. at 42�25'N, 6�3' E. The distance C to A s then about 404 km, and A to S 608 km. The angle of the direction of CERN from due wast as seen from San Sasso is thus roughly ATAN(404/608) = 33.6�. The earth's radius if 6371 km. San Sasso is located at latitude 42.42�N. Its radius of rotations is thus cos(42.4)*(6371 km) = 4720 km. Its speed of rotation is thus 2*Pi*(4720 km)/(24 hr) = 343 m/s. The speed of CERN due to earth's rotation is 2*Pi*cos(46.2�)* (6371 km)/(24 hr) = 321 m/s. The 22 m/s speed difference between CERN and San Sasso is not enough to relativistically affect the measurements, especially given the extreme effort put into clock synchronization and geodetic coordinate location. The relative motion however, is enough. A non-rotating linear motion approximation is sufficient to approximate the expected effect. Light travels 730 km in (730 km)/(3x10^8 m/s) = 2.435x10^-3 s. In that time San Sasso moves d = (2.435x10^-3 s) * (343 m/s) = 0.835 m eastward. The distance x added to the travel can thus be approximated as x = cos(33.6�) * d = 0.833 * (0.853 m) = 0.71 m. The travel time of the neutrinos should be increased by (0.71 m)/(3x10^8 m/s) = 2.36x10^-9 s = 2.36 ns. The neutrinos were observed arriving 60.7 ns early. This extra 0.71 m, 2.36 ns, had it not been taken into account, would have made the neutrino arrival time 60.7 ns + 2.4 ns = 63.1 ns early vs speed of light. Failure to account for earth's rotation thus provides approximately a 2.4/60.7 = 4 % error. However, this error is in a direction which makes the anomaly even greater.

Buy a MSP430 microcontroller board for $4.30 incl. shipping from TI: https://estore.ti.com/Search.aspx?detail=1k=MSP-EXP430G2 and buy a 3-axis sensitive magnetometer at Digikey för $3.79: http://search.digikey.com/scripts/DkSearch/dksus.dll?Detailname=342-1082-1-ND Put them together via I2C with some soldering and maybe some voltage level adaptions and have the MSP430 send the data over USB to a PC that logs everything and send the measured data to some site on Internet. This setup is 10 times cheaper than the Imagesco stuff and better since everything is logged. If you can't detect a UFO with this device, which should be very unlikely, you will likely be able to detect the expected big magnetic storms originating from solar eruptions expected this and next year.

David David Jonsson, Sweden, phone callto:+46703000370 I don't know that a simple model like springs connecting the molecules works for a liquid, but here's a way to connect the concepts: So what would be used then? Thanks for your contribution. What I actually is trying to determine is to find the speed of the molecule in specific directions. If I have the spring constant then it is easy to determine the temperature. And as you can guess from earlier postings I will determine centrifugal effects based on these velocities. A ball park estimate is that it is just a little lower than for gases at the same temperature. Assume that the speed i gases is the same for fluids and solids. When the molecule is in the middle when the spring potential energy is zero all energy has to be in the kinetic energy of the molecule and thus be the same as for gas molecules when they fly freely without collision. And the means speed of something in periodic oscillation is the maximum speed/2^½ ~ 0.7 of the max speed and mean RMS speed is 0.5 of max speed. This means that the variations in vertical acceleration for molecular motion (the Eötvös effect) has the same formula as for gases but with proportionality factors of 0.5 or 0.7. The tangential effect is still under investigation by me and I currently investigate two or three alternatives. The Eötvös effect on atomic and molecular motion is very interesting. It means that water and rock on Earth weighs 0.04 % less than their mass. This should be detectable. The effect is proportional to the temperature. Imagine the effect on hotter places like the interior of planets and stars. Good. The problem appeared to be somewhat simpler than I first thought. It is interesting to see that centrifugal variation is independent of the oscillation frequency of the molecule. I really needed this since I will present the results in less than three weeks:-) I think the model error is less than 2% based on the difference between isothermal and adiabatic bulk modulus, found here: http://physchem.kfunigraz.ac.at/sm/service/water/H2Obetat.htm Greetings from the Bergian Garden in Stockholm, David

You can know with certainty before you start that the effect you're claiming isn't going to show up in your gedanken, unless arithmetic itself is logically inconsistent! If momentum is conserved, then total impulse on the ball due to impacts with the sides of the box, over a period of time, must exactly negate the total impulse delivered by gravity. Otherwise the ball's net momentum will change, and it obviously doesn't (at the end of the experiment, in the middle of a cycle, the ball's moving at the same speed it was, in the middle of a cycle, at the beginning of the experiment). Net weight of the ball is the average force needed to hold it up, which is the total impulse delivered to it divided by the total time.

[Vo]:Another view on superrotation
Superrotation is shear flow on gas planets and stars and it requires an explanation since there appears to be no force or stress to drive them. Recently I came up with the following idea after having tried two others with limited success. Assume that gas or matter flowing along planets' or stars' rotation around its axis is less affected by viscous drag compared to flow going against the. This is because of differences in centrifugal acceleration between these two cases. Matter being less affected by gravity due to centripetal acceleration pushes less on the underlying matter and will have its viscous shear stress reduced. In a gas or other fluid with thermal motion there will be particles moving in any direction and they will be slowed down differently depending on direction of motion relative the rotational direction. How could this be quantitatively determined? If another more practical and smaller size example helps you to better imagine the physical situation you can think of a gas centrifuge for uranium enrichment. There should be high shear flow in that case as well and not as we are erroneously informed on various places on Internet that there is solid body rotation. Does anyone here think it is correct to lie about physics in order to stop understanding of it and thus prevent proliferation of technologies based on the effect? It is both impressive and disgusting that someone has been capable of keeping this kind of physics undeveloped for over a century.

Because, as we said before, the emitted ray is independent of the emitting device's velocity. That way, absolute motion will be detected in the direction at which the time delta is greater. The light ray will take longer, travelling at a fixed velocity, to reach the receiving device, because the travel distance in that direction will be greater. Again, because the receiving device will be moving away while the light ray is travelling towards it. If this is not the case, we must postulate that the movement of the emitting device affects the velocity of the ray of light. And therefore c is not constant. Or, we must postulate that the medium is moving solidary with the experimental setup. And we have detected ether entrainment. Take notice that I'm not talking about relativistic effects, because there are none. The emitting and receiving devices are both solidary. That is, their relative velocity is zero. [/SNIP] Mauro, I have only read the Consoli Constanza abstract so far http://arxiv.org/abs/astro-ph/0311576 and was looking at the pdf when your new thread arrived so I will first reply to you and then delve further into the paper you recommended. I don't agree that measurements from your device would vary with direction other than mechanical limits of perfectly matching multiple light sources and measuring devices but I have to admit that I haven't yet studied these lesser deviations that you mention which were measured in the MM experiment or their significance. You seem to imply a much lower than expected difference was measured but I am not clear on what significance you ascribe to these values. The biggest hurtle with your alternative measurement remains that we are already at the limit of measurement devices using fringe patterns. I can see the merit of your relative measurements to any pattern CHANGES as you rotate the device between the X,Y,Z axis, It could easily mitigate what we saw gravity do to the measurements last year of a vertically designed MM fixture - but I am unsure if the opposite fringe patterns would have any meaningful static relationship to each other -your hope would be a min/max measured beam delay in one orientation that reverses to max/min measured beam delay when you reverse the orientation? Yes. I'm propossing using light detectors and synchronized clocks(very precise clocks) to measure the differences in departure and arrival times in one-way travel, instead of using interferometers in two-way travel. I suggest you to take the time to reflect on the experiment, and to evaluate the possible outcomes and its consequences. Reading about the Sagnac effect is probably also a good idea. The proposed experiment is probably not easy to perform, because of the needed precision and stability of the clocks. Although it must be feasible, given current technology. I would not expect any changes at all since my premise is that any spatial direction is 90 degrees displaced from time so spatial direction becomes unimportant and only changes in velocity if measured relative to another inertial frame would reveal changes in the rate at which the ether intersects with our spatial axis. Perhaps measuring changes in the half lives of radioactive gas caused by a catalyst or the propagation time of a laser through the lower energy density of a Casimir cavity would reveal more about the ether and it's orientation than revealed by the MM technique. I still refer to the ether as having an orientation even though it remains forever in a hidden dimension from within one's own inertial frame because we know that highly accelerated objects shift to a different angle between time and space from our perspective

That leads to an apparent change in electron mass since it increases the magnetic reluctance of the electron. Since the mass and charge relation of an electron is fixed it is impossible to distinguish if an apparent increase in inertia of the electron is due to mass increase or change in its magnetic field.

[Vo]:More change regarding rotating gas: less shear and new normal stress variations
I had to adjust my calculations again because of failures of the previous calculations. It is significantly simplified and the torque effect is now much lower than in previous versions. I can no longer explain the Venusian winds. One thing I still wonder about is how an equilibrium could be established. Since no net rotation acceleration is taking place in the gas some counter shear stress is taking place and I wonder if the shear stress from the observed shear flow could be balancing the effect. This explains why the flow is contrary to derived shear. On the other hand that shear is horizontal and the derived stress is vertical. I ask you to visit http://arxiv.org/abs/1012.1381 and tell me what you think, Critique is appreciated as well as affirmations. I also have some idea on how to calculate on liquid and solid matter and on plasma. The funny thin is that my initial estimate on plasma is that electromagnetic fields can establish due to the effect. I also plan to include normal stress variations that are also due to thermal motion into the same article.

It will be very interesting to see inf the normal stress component significantly alters the scale height ( http://en.wikipedia.org/wiki/Scale_height ) H = kT/Mg of the atmosphere. That would be a real breakthrough. g in that formula is dependent on thermal motion as show in the Physicsforum thread. Another thing is that not very deep down in the atmosphere it will be so hot that there will be ionization with free electrons. Electrons are so lightweight and fast that the thermal effect on their centripetal acceleration makes their g value very much lower than the ions and thus produce an electric field directed inwards. I find it very interesting and I am surprised it hasn't been investigated. I have read something about an electric field on Jupiter or Saturn. On the Earth it is varying over the day between 80-120 V/m. I wonder how much the thermal stress contributes to that.

As I am reading though it, I am hoping to find any suggestions towards the intriguing question posed in the opening – that the winds on Saturn are incredibly fast and blow 500 m/s faster than the planet. Why or how did your original model answer that? Is there an electrical component? Also there is the old problem – does such a fast wind blow only in one direction? That one has possibly been answered – it blows both ways. How could this not create more stress, not less? Obviously you did not set out to answer these questions about the winds on Saturn, but I am left asking – if there is anything new that we know before ? It might be wise to limit the reader’s expectations at the start.

It is significantly simplified and the torque effect is now much lower than in previous versions. I can no longer explain the Venusian winds. One thing I still wonder about is how an equilibrium could be established. Since no net rotation acceleration is taking place in the gas some counter shear stress is taking place and I wonder if the shear stress from the observed shear flow could be balancing the effect. This explains why the flow is contrary to derived shear. On the other hand that shear is horizontal and the derived stress is vertical. I ask you to visit http://arxiv.org/abs/1012.1381 and tell me what you think, Critique is appreciated as well as affirmations. I also have some idea on how to calculate on liquid and solid matter and on plasma. The funny thin is that my initial estimate on plasma is that electromagnetic fields can establish due to the effect. I also plan to include normal stress variations that are also due to thermal motion into the same article.

Classical acceleration ac = vs^2/r compared to a is a/ac=(vs^2 + vp^2/2)/r/(vs^2/r) = (vs^2 + vp^2/2)/r/(vs^2/r) = (220^2 + 500^2/2)/220^2 = 3.6 So in this case the gravitational pull has to be 3.6 times higher than even the dark matter addition.

Don't think so. In Newtonian terms, the acceleration's centripetal, caused by the centripetal force, which is provided by gravity. The fictitious centrifugal force is the outward-pointing acceleration of a uniformly moving non-rotating object (times its mass) which is observed from a rotating frame. However, in the rotating frame, the acceleration you're concerned with -- and the acceleration which leads to the centrifugal force -- is directed inward, and is centripetal. If I didn't understand incorrectly, what David is saying is that when you determine G empirically, by example by using a scale, centrifugal acceleration must be discounted, because it's affecting the scale weights. That is, the scale weights are subjected not only to gravitation, but also to a centrifugal force, because they are inertial masses in rotation. And also translation, by the way. To be extremely precise, you would also need to consider the component of Earth's acceleration around the Sun, and other accelerations. I suppose all those influences must be much smaller than variations in G due to ambiental and geographical factors. The same for the difference between sidereal and solar day, probably.

How big is the anomalous acceleration at our solar system? If you're talking about the anomalous acceleration of the solar system around the milky way, you can calculate it using the centripetal acceleration formula. I've calculated it in the past. If the Sun is rotating around the galaxy at 220 km/s, and the distance to the center of the Milky Way is ~ 26000 light years, and assuming we're orbiting the galaxy in a circle(which sounds like a good approximation) the Sun must be subjected to a centripetal acceleration ac = v^2/r ~= 2 x 10^-10 m/s^2 Right, and how big is the mass of the galaxy inside the orbit of the solar system. I also need that to determine the error. I calculated the anomalous effect from my paper and the acceleration was on the order of 10^-26. Apparently too weak and in the wrong direction, or a mistaken calculation.

[Vo]:A rotating molecule on a rotating planet appears lighter than a non rotating molecule
Hi I was calculating and found a strange thing. It seems like a rotating molecule is less effected by gravity compared to a non rotating molecule. Imagine a diatomic molecule at the equator of a rotating planet. The molecules has its axis of rotation parallel to the planets axis. It seems to me that the centrifugal force on the molecule is different when the molecule rotates and when it is not rotating. Speed of surface of the rotating planet = v Radius of planet = r Speed of the atoms in the rotating molecule = u Mass of molecule = m ,(m/2 for each atom) In the non rotating case the centrifugal force on the gas molecule becomes: f = m v^2 / r If the molecule rotates the centrifugal force is different on the two atoms it consists of. Lets take the case when the molecule is vertical like this O rotation of upper atom I O rotation of lower atom rotation of planet --Planet surface--- The centrifugal force on the upper atom becomes fu = m / 2 * (v+u)^2 / r and on the lower fl = m / 2 * (v-u)^2 / r adding the forces together to find the net effect gives f = fu + fl = m / 2 * (v+u)^2 / r + m / 2 * (v-u)^2 / r = = m / 2r * ((v+u)^2+(v-u)^2) = = m / 2r * (v^2+2uv+u^2+v^2-2uv+u^2) = = m / r * (v^2+u^2) The effect is of course smaller at other positions of the molecule and the mean value over an entire revolution would be somewhat lower but still higher than the case when the molecule is not rotating. It seems that the centrifugal force on the molecule is higher when it rotates. Since the centrifugal force is opposed to gravity it means that the rotating molecule would be less affected by gravity than the rotating one. Can this really be the case? It has to apply to all rotating matter and not only molecules as for example a rotating planet around a star. Have I done something wrong? David David Jonsson, Sweden, phone callto:+46703000370

Maybe some other effect is balancing this effect to make orbits stable? Rotation of the elongation due to tidal effect also complicates things. I can imagine that only certain combinations of tidal elongation and rotation exists. Is the bulge of the elongation always between 0 to pi/2 radians from the direction to the other body?

Are you saying that gravity behaves in the traditional (Newtonian) way inside solid bodies? Do you have links or papers to experiments that support this? As I said, there are reported anomalies inside boreholes. How do you or others explain them? Take into account that although gravity can be related to mass and density, that is, it can have a dependency on mass and density, that does not mean mass and density are the causes of gravity. Indeed, it makes a lot of sense to think just the opposite: that which causes mass (or the effects of mass) has to be massless in itself, to avoid a circular argument. The cause of gravity must be immune to the effects of gravity, by the very definition of cause.

[Vo]:Super rotation, high wind speeds
Hi The higher rotation of outer layers of planets continues to occupy me. They are very common on Earth, Venus, Saturn and Jupiter. Even the Sun has it an even other stars. I have begun to think of an explanation where pressure and viscosity changes due to rotational speed in the upper atmospheres or upper fluid layers. The basics is that fluid flowing along the rotation is less affected by gravity since they have a centrifugal force associated with them. This is also valid for the molecular motion. Any gas on a planet or any liquid on a star has molecular motion in making centrifugal effects different on the molecular level. Fluid flowing faster than the solid body rotation speed cause less pressure on lower gas and hence lower viscosity making motion for the fluid along the solid body rotation direction easier than flow against it. That could be the reason behind all these apparently strange higher rotation speeds found practically everywhere where. It could be present even on galaxies since they use the concept of viscosity even there. The effect could thus maybe lower the need for dark matter. Can someone help me to determine the effect and find out if it is significant on any know astronomical body? David David Jonsson, Sweden, phone callto:+46703000370

[Vo]:Solar internal rotation driven by convection?
Hi I was glancing at the title SOLAR CONVECTION AND INTERNAL ROTATION: http://www.hao.ucar.edu/research/siv/siv_convection.php Convection can not drive rotation. Convection is caused by temperature gradients and gradients can not cause rotation. Am I wrong? The same argument was once used to disprove rotational electromagnetic engines which apparently do exist. And when I think about it the water in water filled heaters does circulate. It could ofcourse be the same apparently but physically not rotational movement as in a vortex.

[Vo]:Weak understanding of forces on molecules
I read of molecule of the month bombykol http://www.chm.bris.ac.uk/motm/bombykol/bombykolh.htm It struck me that the forces between molecules are not well understood. The force is just a distance dependency on a energy potential. Higher orders of electromagnetic energy potentials should be investigated. And I am not sure about the antenna design. It looks like electrodynamic effects of it. I would ask for someone investigate the molecular spectrum of bombykol and see if it coincides with the harmonic frequencies of the moth antenna. Something similar to Casimir forces could be the effect on the molecule. Casimir forces should be understood as something limiting the electrodynamical spectrum making the energy varying and thus act as force on the molecule. Casimir effect is not only active for ZPE but for any radiation. For some other insect they proved that they could detect a chemical even when it was too scarce in concentration to reach the antenna. This could be explained as either a radio detection, or, which is plausible since the receptors are dependent on physical presence of a molecule, that the antenna attracts the molecules. What do you say? David David Jonsson, Sweden, phone callto:+46703000370
[Vo]:High frequency UV radiation = VUV
The special thing about 159 nm is that it is almost entirely absorbed by air and ionizing it. Ionized air can be affected by other radiation to be heated. Heating localized air around a body makes a push on it. I want to elaborate with propulsion of this kind. UV with shorter wavelenght than 159 nm is called VUV, vacuum ultraviolet, since it can only exist in vacuum. It is absorbed by air. Very funny would be to have tunable UV on the border between UV and VUV. The absorption rate would then be adjustable and the radiation could pass arbitrarily far away ffrom the radiation source. I want to heat air around an object as described in my arXiv article on preventing shock waves. I think that the same technique can be used to achieve propulsion as well and it could be the way that flying saucers operate. They fly with apparently no moving parts and UV/VUV in combination with heating could have the same effect. I see that many vacuum UV lights can be bought: http://www.google.se/search?hl=enq=vacuum+uv+lamp David David Jonsson, Sweden, phone callto:+46703000370
