Background: When we ride on a roller coaster, our experience of self-motion is accompanied by salient changes in gravitoinertial force. Here we examined whether a similar relationship exists between visually induced self-motion (vection) and perceived gravitoinertial force. Methods: There were 15 stationary subjects, each wearing a weight jacket, who were exposed to visual displays simulating upward, backward, or no self-motion. At the end of each 30-s display exposure, subjects: 1) rated the strength of their vection experience; and 2) had the experimenter add/remove weights from their weight jackets to recreate their perceived weight during exposure to the stimulus display. Results: We found that upward vection increased and downward vection decreased perceived weight. Importantly, the size of these perceived weight changes depended on the strength of the vection experience. Conclusions: We conclude that the observed strong relationship between vection and perceived weight stems from the brains

Spawning market squid lay embryo capsules on the seafloor of the continental shelf of the California Current System (CCS), where ocean acidification, deoxygenation and intensified upwelling lower the pH and [O2]. Squid statolith geochemistry has been shown to reflect the squids environment (e.g., seawater temperature and elemental concentration). We used real-world environmental levels of pH and [O2] observed on squid-embryo beds to test in the laboratory whether or not squid statolith geochemistry reflects environmental pH and [O2]. We asked whether pH and [O2] levels might affect the incorporation of element ratios (B:Ca, Mg:Ca, Sr:Ca, Ba:Ca, Pb:Ca, U:Ca) into squid embryonic statoliths as (1) individual elements and/or (2) multivariate elemental signatures, and consider future applications as proxies for pH and [O2] exposure. Embryo exposure to high and low pH and [O2] alone and together during development over four weeks only moderately affected elemental concentrations of the statoliths, and
There is far less study of the refining effect of super gravity fields on solidification structures of metals than of the effects of electrical currents, magnetic and ultrasonic fields. Moreover, the refining mechanisms of super gravity are far from clear. This study applied a super gravity field to Al-Cu alloys to investigate its effect on refining their structures and the mechanism of interaction. The experimental results showed that the solidification structure of Al-Cu alloys can be greatly refined by a super gravity field. The major refining effect was mainly achieved when super gravity was applied at the initial solidification stage; only slight refinement could be obtained towards the end of solidification. No refinement was obtained by the super gravity treatment on pure liquid or solid stages. The effectiveness of super gravity results from its promoting the multiplication of crystal nuclei, which we call

The Force of Gravity: Newton vs. Einstein. In Newtonian mechanics gravity is considered to be a real force, despite the fact that it shares the first two properties of fictitious forces listed. This makes Newtonian gravity a bit of a strange force. You cannot determine if a given reference frame is inertial or not simply by using accelerometers, you have to additionally know the distribution of mass nearby in order to correct your accelerometer readings for the presence of gravity.. In GR, this is simplified by considering gravity to be a fictitious force just like any other force which is proportional to the mass and cannot be measured by an accelerometer. This means that in GR an apple in free fall to the ground is considered to be inertial, while in Newtonian gravity the apple is non-inertial. Similarly, the rest frame of the free-falling apple is an inertial frame in GR with no fictitious forces, while in Newtonian mechanics it is a non-inertial frame with a fictitious force that is equal ...

Plants can sense the Earths gravitational field. Geotropism is the term applied to the consequent orientation response of growing plant parts. Roots are positively geotropic, that is, they will bend and grow downwards, towards the center of the Earth. In contrast, shoots are negatively geotropic, that is, they will bend and grow upwards, or away, from the surface.. These geotropisms can be demonstrated easily with seedlings grown entirely in darkness. A seedling with its radicle (or seedling root) and shoot already in the expected orientation can be turned upside down, or placed on its side, while kept in darkness. The root will subsequently bend and grow downwards, and the shoot upwards. Because the plant is still in darkness, phototropism (a growth movement in response to light) can be eliminated as an explanation for these movements.. Several theories about the manner by which plants perceive gravity have been advanced, but none of them is entirely satisfactory. To account for the positive ...

Hi Sabine, Thanks for your insights. I have been interested in the possibility of negative gravitational masses for quite a time now, and it seems that theres still a lot of confusion, be it in my mind or in the scientific community. First, there is something you say that is deeply confusing. How can General Relativity (GR) be compatible with like charge attraction and unlike charge repulsion? This would immediately imply that theres a violation of both (weak and strong) equivalence principles, which are fundamental to the validity of GR. Lets say we bring a negative gravitational mass near Earth gravitational field: because its gravitational mass is negative and its inertial mass positive it will be repeled by it, whereas a positive gravitational mass will be attracted by it. GR equations cant do that, because the space time curvature is imposed by the Earth field, it is thus positive, and every type of mass should thus fall! It seems to me that Bondi type negative masses are more ...

DNA perturbs the gravity field by providing a contiguous non-destructive spin path of phase coherent heterodyning THRU THE SPEED OF LIGHT. Carl Jung once wrote extensively about how intense human awareness cracked a huge tree stump in his room. Any good kundalini afficionadoe like me or Enki could tell you of the gravity effects of intense human glandular electromagnetic fields. Another example is the floating of meditators in seeming zero G so well documented in the photos in the TM schools.. What none of these sources has yet explained is WHY. Why do glands and genes on fire make gravity? Actually what you do when you float, is pay your debt to gravity. Once you understand HOW DNA on fire bends gravity fields - you begin to understand the need of star systems for symbiotic genepools - who becomes self aware enough to steer their gravity fields..

Agree, push gravity does not work assuming gravity is a particle or a wave. Push Gravity only works on a Flat Earth assumption where Earth is enclosed, or contained, and space does not exist. Gravity is a result of atmospheric, electrical, & other pressures. I balanced a raw egg on its sharp end on my kitchen table for about 30 minutes, which means all forces acting on the egg were perfectly balanced with the exception of the vertical downward push. If the table was level and located on the side of a hill, the egg could still be balanced ...

Downloadable! We analyze two main theories of international trade, the Heckscher-Ohlin theory and the Increasing Returns trade theory, by examining whether they can account for the empirical success of the so-called Gravity Equation. Since versions of both models can generate this prediction, we tackle the model identification problem by conditioning bilateral trade relations on factor endownment differences and the share of intra-industry trade, because only for large factor endowment differences does the Heckscher-Ohlin model generate specialization of production and the Gravity Equation, and it predicts inter-, not intra-industry trade. There are three major findings: First, little production is perfectly specialized due to factor endowment differences, making the perfect specialization version of the Heckscher-Ohlin model an unlikely candidate to explain the empirical success of the Gravity Equation. Second, increasing returns are important causes for perfect product specialization and the Gravity
The surge of interest in filters to provide safe drinking water during emergencies has led to a lot of misunderstanding about water purification. One major misconception is that you have to buy a $300 gravity filter or costly miniature hand-pump system to purify water. Siphoning, an eons-old trick, will drive a water filter as well as a pump, and a simple siphon can work much better than an expensive commercial gravity filter. With our simple equipment, you can have a siphon filter that will make plenty of biologically safe drinking and food-preparation water for several people from the grossest puddles of water. A siphon filter works much faster than a canister-type gravity filter, and once you get it going, it keeps on producing water without a lot of huffing and puffing and pumping and complaining on your part. Any of the simple, inexpensive filters described below will outperform a miniature pump filter or an expensive gravity pot. Before you read about the products below, you should ...
Abstract: If gravity is an emergent phenomenon, as suggested by several recent results, then the structure of the action principle for gravity should encode this fact. With this motivation we study several features of the Einstein-Hilbert action and establish direct connections with horizon thermodynamics. We begin by introducing the concept of holographically conjugate variables (HCVs) in terms of which the surface term in the action has a specific relationship with the bulk term. In addition to g_{ab} and its conjugate momentum \sqrt{-g} M^{cab}, this procedure allows us to (re)discover and motivate strongly the use of f^{ab}=\sqrt{-g}g^{ab} and its conjugate momentum N^c_{ab}. The gravitational action can then be interpreted as a momentum space action for these variables. We also show that many expressions in classical gravity simplify considerably in this approach. For example, the field equations can be written in a form analogous to Hamiltons equations for a suitable Hamiltonian if we use ...
To display more clearly the gravity anomalies caused by geologic bodies in the upper parts of the crust, a new colored isostatic residual gravity map of the conterminous United States has been prepared using the gravity data set compiled for the Gravity Anomaly Map of the United States (Society of Exploration Geophysicists, 1982). The new isostatic residual gravity map is based on an Airy-Heiskanen model of local compensation, in which the surface load requiring compensation is defined by 5-min topographic and bathymetric data sets. A colored first-vertical-derivative map of isostatic residual gravity further enhances the short-wavelength anomalies produced by bodies at or near the surface and emphasizes the regional fabrics and trends in the gravity field. For the purpose of displaying gravity anomalies caused by shallow bodies of geologic significance, the nature of the isostatic model and the values of its parameters are of lesser importance than the application of an isostatic correction of ...
Downloadable! Short run gravity is a geometric weighted average of long run gravity and bilateral capacity. The model features (i) joint trade costs endogenous to bilateral volumes, (ii) long run gravity as a limiting case of effcient investment in bilateral capacities, (iii) a structural ratio of short run to long run trade elasticities equal to a microfounded buyers’ incidence elasticity, and (iv) tractable short and long run models of the extensive margin. Application to manufacturing trade of 52 countries during the globalization period 1988-2006 strongly supports the model. Results solve several time invariance and trade elasticity puzzles in the literature.

The explanation of the test is this: If the heavy weight is removed due to a truly random number on the random number generator, it is likely to not have been removed in most AUs, meaning its gravity may still be detectable with a sensitive detector. The weight may need to be in place for at least a month or so, and be removed very quickly, with the detector measuring constantly to detect any variation of what would normally be expected. I propose that gravity is the strong force leaking through from countless AUs where the masses are shifting (diffusing) in physical location due to differing laws of physics. The Earth may even be disintegrating into separate atoms in these AUs. This gradient of mass/strong force would then pull atoms toward this higher concentration that exists in the multiverse ...
Gravity Pulls You In gives voice to whats hard about raising a child with ASD without feeding the stereotype of the devastation of autism. There are stories of discovery and enlightenment, of perseverance and humor that forge a deeper connection among parents by broadening the perspective on autism and attempting to dismantle the fear. The children written about range from toddlers to adults, and from high functioning to severely affected. Despite times of heartache and disappointment, the contributors describe learning things from their children that are transforming, of being awestruck by their kids hearts and minds and the glimpses of their son or daughters personality, humor, or wisdom.

Gravity also acts at a distance, without an apparent energy source. But to get energy out of a gravitational field (for instance, by dropping a heavy object, producing kinetic energy as it falls) you have to put energy in (for instance, by lifting the object up), and some energy is always dissipated in the process. A typical application of gravity in a perpetual motion machine is Bhaskaras wheel in the 12th century, whose key idea is itself a recurring theme, often called the overbalanced wheel: Moving weights are attached to a wheel in such a way that they fall to a position further from the wheels center for one half of the wheels rotation, and closer to the center for the other half. Since weights further from the center apply a greater torque, the result is (or would be, if such a device worked) that the wheel rotates forever. The moving weights may be hammers on pivoted arms, or rolling balls, or mercury in tubes; the principle is the same.. Yet another theoretical machine involves a ...

The most important conclusion of the system design is that all the systems are interrelated. The universe stands on two principle forces - gravity and anti-gravity. Gravity comes from matter and anti- gravity comes from life that is enclosed in it. It notes that gravity has its base in fundamental non-equilibrium or asymmetry in its left and right frame, which acts as centripetal force. The life and its process come from a form of symmetry between its left and right frame and thus produces anti- gravity. Here it notes that human systems [argon based systems plays an important role]. These systems structural configuration separates it from the external environment and its own internal core. Thus it becomes incapable of perceiving universal time and changes in it. It solely depends on information development to survive the stress force acting on it. It wrongly perceives danger as coming from the outside world and thus sets out to conquer and corrupt nature thus stressing the inner core. In one ...
The stream of consciousness came during a restorative yoga. I tried to break down the concept of why gravity is what it is. What causes it? I got down to the smallest thing of the quark. Does gravity affect quarks or do quarks "make" gravity? In this article (which I dont claim accuracy, its still a stream of thought) about Quarks, Wormholes and Gravity it speaks of possible connections of Quantum Entanglement and gravity.. Quantum Entanglement speaks of a quark having an equal and perhaps opposite quark existing. When one moves, the other moves as well, as my basic understanding in the opposite.. Some of us think (some know) that there is this spiritual energy "out there". A higher power, a higher self, God, the Universe, and many other names. Synchronicity happens, some see ghosts, some see angels, mysterious things that cant be explained by our understandings happen, and those "damned facts"..

B.F.L. Ward, Baylor University. Asymptotic Safety and Resummed Quantum Gravity. In Weinbergs asymptotic safety approach to quantum gravity, one has a finite dimensional critical surface for a UV stable fixed point to generate a theory of quantum gravity with a finite number of physical parameters. The task is to demonstrate how this fixed point behavior actually arises. We argue that, in a recently formulated extension of Feynmans original formulation of the theory, which we have called resummed quantum gravity, we recover this fixed-point UV behavior from an exact re-arrangement of the respective perturbative series. We argue that the results we obtain are consistent both with the exact field space Wilsonian renormalization group results of Reuter and Bonanno and with recent Hopf-algebraic Dyson-Schwinger renormalization theory results of Kreimer. We calculate the first "first principles" predictions of the respective dimensionless gravitational and cosmological constants and argue that they ...
