1970 3. E. Babichev, C. De ayet, and R. Ziour, The recovery of general relativity in massive gravity ...Unreferenced date January 2010 In theoretical physics , massive gravity is a particular generalization of general relativity studied by Hendrik van Dam , Martinus J. G. Veltman 1 , and Vladimir E. Zakharov . 2 One assumes that physics takes place in Minkowski space and gravity is caused by a massive spin physics spin 2 field h that couples to matter like the graviton , namely by the term math h mu nu T mu nu math where T is the stress energy tensor . The adjective massive means that there are also mass terms in the Lagrangian proportional to math h mu nu h mu nu math . At distances shorter than the corresponding Compton wavelength , one recovers the Newton s gravitational law . In the same limit, however, the bending of light is only three quarters of the result Albert Einstein obtained in general relativity. This is known as the vDVZ discontinuity . More technically stated by E. Babichev, et al 3 , The quadratic Pauli Fierz theory is known to suffer from the van Dam Veltman Zakharov vDVZ discontinuity,i.e. the fact that when one lets the mass m of the graviton vanish, one does not recover predictions of General Relativity. E.g., if one adjusts the parameters namely the Planck scale such that the Newton constant agrees with the one measured by some type of Cavendish experiment, then the light bending as predicted by Pauli Fierz theory and for a vanishingly small graviton mass will be 3 4 of the one obtained by linearizing GR. The fact that it is smaller is easy to understand the essential difference between Pauli Fierz theory and linearized GR comes from an extra propagating scalar mode present in the massive theory. This mode exerts an extra attraction in the massive case compared to the massless case. Hence, if one wants measurements of the force exerted between non relativistic ...

Gravity Probe A GP A was a space based experiment to test the theory of general relativity , performed jointly by the Smithsonian Astrophysical Observatory and the National Aeronautics and Space Administration . It sent a hydrogen maser , a highly accurate frequency standard, into space to measure the rate change of a clock in lower gravity with high precision. The probe was launched on June 18, 1976 on top of a Scout rocket Scout rocket and remained in space for 1 hour and 55 minutes, as intended. It then crashed into the Atlantic Ocean. Experimental setup The 100  kg Gravity Probe A spacecraft housed the hydrogen maser system that ran throughout the mission, and a microwave repeater to measure the Doppler shift of the maser signal. The satellite was launched nearly vertically upward to cause a large change in the local gravity seen by the maser, reaching a height of convert 10,000 km mi abbr on . At this height, general relativity predicted a clock should run 4.5 parts in 10 sup 10 sup faster than one on the Earth. Results Expand section date January 2007 The clock rate was measured from the ground by comparing the microwave signal from the clock to a maser on the ground and subtracting a signal from the spacecraft that measured the Doppler shift. The clock rate was measured for most of the duration of the flight and compared to theoretical predictions. The stability of the maser permitted measurement of changes in the rate of the maser of 1 part in 10 sup 14 sup for a 100 sec measurement. The experiment was thus able to test the equivalence principle . Gravity Probe A confirmed the prediction that gravity slows the flow of time, and the observed effects matched the predicted effects to an accuracy of about 70 parts per million.

inline date July 2009 Recovery is a process by which deformed grains can reduce their stored energy by the removal or rearrangement of defects in their crystal structure. These defects, primarily dislocations , are introduced by plastic deformation of the material and act to increase the yield strength of a material. Since recovery reduces the dislocation density the process is normally accompanied by a reduction in a materials strength and a simultaneous increase in the ductility. As a result recovery may be considered beneficial or detrimental depending on the circumstances. Recovery is related to the similar process of Recrystallization metallurgy recrystallisation and grain growth . Recovery competes with recrystallisation, as both are driven by the stored energy, but is also thought to be a necessary prerequisite for the nucleation of recrystallised grains. It is so called because there is a recovery of the electrical conductivity due to a reduction in dislocations. This creats defect free channels, giving electrons an increased mean free path. Definition The physical processes that fall under the designations of recovery, recrystallisation and grain growth are often difficult to distinguish in a precise manner. Doherty et al. 1998 stated blockquote The authors have agreed that ... recovery can be defined as all annealing processes occurring in deformed materials that occur .... If recovery occurs during deformation a situation that is common in high temperature processing then it is referred to as dynamic while recovery that occurs after processing is termed static .
