"E=MC 2 " is a speculative poem written by American advertising executive and television advertising pioneer Rosser Reeves. It was published in the September, 1961 issue of The Magazine of Fantasy and Science Fiction. The poem describes the end of the Earth (possibly from a nuclear war) as observed by aliens on a distant planet.
The energy and momentum of an object measured in two inertial frames in energy–momentum space – the yellow frame measures E and p while the blue frame measures E ′ and p ′. The green arrow is the four-momentum P of an object with length proportional to its rest mass m 0 .
[70] [71] American physical chemists Gilbert N. Lewis and Richard C. Tolman used two variations of the formula in 1909: m = E / c 2 and m 0 = E 0 / c 2 , with E being the relativistic energy (the energy of an object when the object is moving), E 0 is the rest energy (the energy when not moving), m is the relativistic mass (the ...

A spherical surface like that of the Earth provides a simple example. The location of any point on the surface can be described by two coordinates: the geographic latitude and longitude. Unlike the Cartesian coordinates of the plane, coordinate differences are not the same as distances on the surface, as shown in the diagram on the right: for ...
These include the equivalence of mass and energy (E = mc 2), length contraction (moving objects shorten), [Note 8] and time dilation (moving clocks run more slowly). The factor γ by which lengths contract and times dilate is known as the Lorentz factor and is given by γ = (1 − v 2 /c 2) −1/2, where v is the speed of the object.
The system keeps the user up-to-date about the best route to the destination, and is often updated according to changing factors such as traffic and road conditions. [2] Turn-by-turn systems typically use an electronic voice to inform the user whether to turn left or right, the street name, and the distance to the next turn.
E=MC² is a 1979 studio album by Italian producer Giorgio Moroder. [1] It has been billed as the "first electronic live-to-digital album." [ 2 ] The album's title track peaked at number 4 on Billboard ' s Dance Club/Disco chart.
