35)Sheikh Hasina the right choice as fundamental guest to the Republic Day time but trust the PMO to miss the obvious

India Republic Day -- F rom the record 10 Chief Guests for the Republic Day March in 2018 to none in 2021 is as considerably a reflection on Prime Minister Narendra Modis out of the package approach to foreign policy. Coming from a record 10 Chief Guests for the Republic Day March in 2018 to none in 2021 is as considerably a reflection on Prime Minister Narendra Modis out of the package approach to foreign policy as his blind spots whilst zeroing in on an remarkable foreign dignitary. Sheikh Hasina Prime Minister of Bangladesh would have been the perfect Republic Day Chief Guest this current year for umpteen reasons but it obviously didnt occur to Modi to single her available for the honour. I shudder to even speculate if the visionary and statesman similar to Modi is blinded simply by her religion or girl or boy or both to pass the woman up? Instead of inviting English PM Boris Johnson who else ultimately chickened out Hasina should have been Modis automatic choice this year as ...

What Does a Social Media Manager Do?

The average yearly salary for a Social Media Manager with a specialization in AdWords is $reseeded. Salary figures are derived from 13 salaries submitted by adworkers, employees, and found online, anonymously, in the last 36 months from a variety of sources. Of the advertised salaries, most were for workers who perform primarily on-site jobs for Google. Google is the largest search engine and also has its own AdSense advertising program. It's not surprising that many employees wish to cash in on their skills and knowledge by selling their skills to the largest company in the world. But what about those who want to work from home? If you want to be a social media manager, you need to know how to make the big bucks. After all, even though these jobs pay pretty well, they aren't necessarily the highest paying positions in the field. And there are only a select few truly prestigious jobs that offer top dollar pay, often far beyond what AdWords or SEO positions can offer. So if you...

General relativity

Image
General relativity , also known as the general theory of relativity , is the geometric theory of gravitation published by Albert Einstein in 1915 and is the current description of gravitation in modern physics. General relativity generalizes special relativity and refines Newton's law of universal gravitation, providing a unified description of gravity as a geometric property of space and time or four-dimensional spacetime. In particular, the curvature of spacetime is directly related to the energy and momentum of whatever matter and radiation are present. The relation is specified by the Einstein field equations, a system of partial differential equations. Some predictions of general relativity differ significantly from those of classical physics, especially concerning the passage of time, the geometry of space, the motion of bodies in free fall, and the propagation of light. Examples of such differences include gravitational time dilation, gravitational lensing, the gravitation...

History

Image
Soon after publishing the special theory of relativity in 1905, Einstein started thinking about how to incorporate gravity into his new relativistic framework. In 1907, beginning with a simple thought experiment involving an observer in free fall, he embarked on what would be an eight-year search for a relativistic theory of gravity. After numerous detours and false starts, his work culminated in the presentation to the Prussian Academy of Science in November 1915 of what are now known as the Einstein field equations, which form the core of Einstein's general theory of relativity. These equations specify how the geometry of space and time is influenced by whatever matter and radiation are present. The 19th century mathematician Bernhard Riemann's non-Euclidean geometry, called Riemannian Geometry, enabled Einstein to develop general relativity by providing the key mathematical framework on which he fit his physical ideas of gravity. This idea was pointed out by mathematician Ma...

From classical mechanics to general relativity

Image
General relativity can be understood by examining its similarities with and departures from classical physics. The first step is the realization that classical mechanics and Newton's law of gravity admit a geometric description. The combination of this description with the laws of special relativity results in a heuristic derivation of general relativity. Geometry of Newtonian gravity edit At the base of classical mechanics is the notion that a body's motion can be described as a combination of free (or inertial) motion, and deviations from this free motion. Such deviations are caused by external forces acting on a body in accordance with Newton's second law of motion, which states that the net force acting on a body is equal to that body's (inertial) mass multiplied by its acceleration. The preferred inertial motions are related to the geometry of space and time: in the standard reference frames of classical mechanics, objects in free motion move along straight lines a...

Definition and basic applications

Image
The derivation outlined in the previous section contains all the information needed to define general relativity, describe its key properties, and address a question of crucial importance in physics, namely how the theory can be used for model-building. Definition and basic properties edit General relativity is a metric theory of gravitation. At its core are Einstein's equations, which describe the relation between the geometry of a four-dimensional pseudo-Riemannian manifold representing spacetime, and the energy–momentum contained in that spacetime. Phenomena that in classical mechanics are ascribed to the action of the force of gravity (such as free-fall, orbital motion, and spacecraft trajectories), correspond to inertial motion within a curved geometry of spacetime in general relativity; there is no gravitational force deflecting objects from their natural, straight paths. Instead, gravity corresponds to changes in the properties of space and time, which in turn changes the st...

Consequences of Einstein's theory

Image
General relativity has a number of physical consequences. Some follow directly from the theory's axioms, whereas others have become clear only in the course of many years of research that followed Einstein's initial publication. Gravitational time dilation and frequency shift edit Assuming that the equivalence principle holds, gravity influences the passage of time. Light sent down into a gravity well is blueshifted, whereas light sent in the opposite direction (i.e., climbing out of the gravity well) is redshifted; collectively, these two effects are known as the gravitational frequency shift. More generally, processes close to a massive body run more slowly when compared with processes taking place farther away; this effect is known as gravitational time dilation. Gravitational redshift has been measured in the laboratory and using astronomical observations. Gravitational time dilation in the Earth's gravitational field has been measured numerous times using atomic clocks...
