Simple Relativity - Understanding Einstein's Special Theory of Relativity
Simple Relativity is a 2D short educational animation film. The film is an attempt to explain Albert Einstein’s Special Theory of Relativity with a simpler visual representation and exciting animation. In a time when our day-to-day life is surrounded by technology, most people find it daunting to understand the science and its application. Simple Relativity is an attempt to excite the viewer about this complex phenomenon of Relativity so that they can approach this, and science in general, with a lot more curiosity rather than inhibition.
n physics, mass–energy equivalence states that anything having mass has an equivalent amount of energy and vice versa, with these fundamental quantities directly relating to one another by Albert Einstein's famous formula:
{\displaystyle E=mc^{2}} {\displaystyle E=mc^{2}}
This formula states that the equivalent energy (E) can be calculated as the mass (m) multiplied by the speed of light (c = about 3×108 m/s) squared. Similarly, anything having energy exhibits a corresponding mass m given by its energy E divided by the speed of light squared c². Because the speed of light is a very large number in everyday units, the formula implies that even an everyday object at rest with a modest amount of mass has a very large amount of energy intrinsically. Chemical, nuclear, and other energy transformations may cause a system to lose some of its energy content (and thus some corresponding mass), releasing it as light (radiant) or thermal energy for example.
Mass–energy equivalence arose originally from special relativity as a paradox described by Henri Poincaré.[1] Einstein proposed it in 1905, in the paper Does the inertia of a body depend upon its energy-content?, one of his Annus Mirabilis (Miraculous Year) papers.[2] Einstein was the first to propose that the equivalence of mass and energy is a general principle and a consequence of the symmetries of space and time.
A consequence of the mass–energy equivalence is that if a body is stationary, it still has some internal or intrinsic energy, called its rest energy, corresponding to its rest mass. When the body is in motion, its total energy is greater than its rest energy, and, equivalently, its total mass (also called relativistic mass in this context) is greater than its rest mass. This rest mass is also called the intrinsic or invariant mass because it remains the same regardless of this motion, even for the extreme speeds or gravity considered in special and general relativity.
The mass-energy formula also serves to convert units of mass to units of energy (and vice versa), no matter what system of measurement units is used.

How to burn a candle underwater. Simple science trick. Watch the flame continue to burn beneath the water level as the wax holds back the water.
It is known from the Earth that it traverses a distance of one meter in 2.15*10-3 seconds; or a second is the time that it takes to move 465 meters. Thus the photon moves 3*108 meters in a second. And if we define the unit of measure on the basis of the photon’s motion, in fact a meter is the distance that the photon travels in 33.33*10-10 seconds. It can, therefore, advance thousands of meters in a hundredth of a second.Let us say that the photon is an object or a physical person who performs his tasks at such an incredible speed; how can he perceive, this fast and cunning photon, the rest of the world?
Know that the photon has a short life but also a long life you’d think that it has seen the whole Universe. If you look at the corners of the Universe, you see flashing lights that come to you and carry the secrets of 13 billion years ago. The photon, as a messenger, revive the past moments; as a little angel illustrates the whole universe; without it, the darkness would dominate the universe… darkness, grief, one over another ... This courageous minuscule has brought us with him the lighting of life, the existence, the heat ..The domain of electromagnetic spectrum is very large and a small region of it is called the Visible Region. It contains packets of elemental energy, from red to violet. Apart from this, there is also the partially visible region that is clearly perceptible for two observer groups. The lower region called Infrared and the upper one called Ultraviolet
n SALEH THEORY, we believe on the helical motion of photon, of which r is the gyroradius around an imaginary axis. This means that the photon has two simultaneous motions: rectilinear motion at constant speed and rotary motion at constant angular velocity.The visible spectrum is one of the concepts that have attracted much comment. In SALEH THEORY the distinction of spectrums is due to the gyroradius; and its changes induce the colorfulness. In fact, the increase of the gyroradius means reciprocally the widening of the wavelength. For example, the long wavelength of the red spectrum is a result of the high value of its gyroradius r, while for the blue spectrum, it’s the opposite.
By focusing laser light to a brightness one billion times greater than the surface of the sun -- the brightest light ever produced on Earth -- the physicists have observed changes in a vision-enabling interaction between light and matter.
What makes the sun shine? How does the sun produce the vast amount of energy necessary to support life on earth? These questions challenged scientists for a hundred and fifty years, beginning in the middle of the nineteenth century. Theoretical physicists battled geologists and evolutionary biologists in a heated controversy over who had the correct answer. Why was there so much fuss about this scientific puzzle? The nineteenth-century astronomer John Herschel described eloquently the fundamental role of sunshine in all of human life in his 1833 Treatise on Astronomy:
I’m going to talk about two of the first science experiments in recorded history. One was allegedly performed by the Prophet Elijah in Israel in the 800s BC [1], the other by the Pharaoh Psammetichus in Egypt in the 600s BC.
