I would have to say no. E=mc^2 is a version of einstein's relativity theory. It means that Energy is equal to Mass times the speed of light squared, and that there is an equivalence betwen mass and energy ( it means that no object with mass can go faster than the speed of light). But it has nothing to do with everything being made of nothing in my opinion. (see http://www.drphysics.com/syllabus/energy/energy.html)

The equation was developed by Coulomb:\n"In physics, Coulomb's law is an inverse-square law indicating the magnitude and direction of electrostatic force that one stationary, electrically charged object of small dimensions (ideally, a point source) exerts on another. It is named after Charles-Augustin de Coulomb who used a torsion balance to establish it."\n\nsee Wikikpedia;\nhttp://en.wikipedia.org/wiki/Coloumb%27s_law\n\nF = Kc * (q1*q2)/r^2\n\nwhere,\nF = force magnitude\n\nq1 = charge on one body\n\nq2= charge on the other body\n\nr = distance between charges\n\nKc = coulomb force constant = 1/(4*pi*epsilon_0) ~ \n8.988×10^9 N m^2 C^-2 \n\nepsilon_0  ~8.854×10−12 C2 N-1 m-2 (also F m-1) is the permittivity of free space, also called electric constant\n\nYour question:\nF = 4*10^-5\nr = 3^10^-2\nq1 = q2 = q\n\n4*10^-5 =  8.988×10^9 * q^2/ 3*10^-2\n12*10^-7 = 8.988×10^9 * q^2\nq^2 = 12*10^-7 / 8.988×10^9 \nq^2 = 1.335 * 10^-16 C\nthen,\nq = 1.155 * 10^-4 C\n\nHope I'm correct, and hope this helps!

E is energy.\nm is mass.\nc squared is the speed of light squared.\n\nThey had a TV show on PBS about Albert Einstein yesterday. You just missed it! \nE=mc squared is Einstein's "theory of relativity".

The theoretical physics equation E = mc2 states a relationship between energy (E) and mass (m) first formulated by Albert Einstein in his 1905 paper "Ist die Trägheit eines Körpers von seinem Energieinhalt abhängig?" ("Does the Inertia of a Body Depend Upon Its Energy Content?", published in Annalen der Physik on September 27), one of the articles now known as his Annus Mirabilis Papers. \n\nIn the context of special relativity theory, the implication is that energy and mass are, in some sense, equivalent. In practical terms, it led to the atomic bomb. It is one of the best-known equations of all time. Even those who may not explicitly know what it means may have some idea of its meaning through culture. Background and consequencesThe equation resulted from Albert Einstein's inquiry into the dependence of mass on its energy content. The famous result of this inquiry is that the mass of a body is actually a measure of its energy content. To understand the significance of this relationship, compare the electromagnetic force with the gravitational force. In electromagnetism, energy is contained in the fields (electric and magnetic) associated with the force and not in the charges. In gravitation, the energy is contained in the matter itself. It is not a coincidence that mass bends spacetime, while the charges of the other three fundamental forces do not. \n\nRest energy = mass X (speed of light)2\n\n\nAccording to the equation, the total amount of energy obtainable from an object is equivalent to the mass of the object multiplied by the square of the speed of light. \n\nThis equation was crucial in the development of the atomic bomb. By measuring the mass of different atomic nuclei and comparing that number with the mass of the individual protons and neutrons, one can obtain an estimate of the binding energy available within an atomic nucleus. This not only showed that it was possible to release energy by fusion of light nuclei or fission of heavy nuclei, but also to estimate the amount of energy which can be released. \n\nIt is a little known piece of trivia that Einstein originally wrote the equation in the form m = L/c² (with an "L", instead of an "E", representing energy). \n\nA kilogram of mass completely converts into \n89,875,517,873,681,764 joules or \n24,965,421,632 kilowatt-hours or \n21.48076431 megatons of TNT \napproximately 0.0851900643 Quads (quadrillion British thermal units) \n\n\nIt is important to note that practical conversions of mass to energy are seldom 100 percent efficient. One theoretically perfect conversion would result from a collision of matter and antimatter; for most cases, byproducts are produced instead of energy, and therefore very little mass is actually converted. In the equation, mass is energy, but for the sake of clarity, the word converted is used. \n\nAccording to Umberto Bartocci (University of Perugia historian of mathematics), the equation was first published two years earlier by Olinto De Pretto, an industrialist from Vicenza, Italy, though this is not generally regarded as true or important by mainstream historians. Even if De Pretto introduced the formula, it was Einstein who connected it with the theory of relativity. Applicability of the equation E=mc² applies to all objects with mass, as it is a statement that mass is energy. Its applicability to moving objects depends on the definition of mass used in the equation.

Really basically, E=mc^2 (be sure to always write m and c as lower case) is the relationship between rest mass and energy. The conversion is pretty simple. The constant c is the speed of light defined as 299,792,458 m/s.\n\nWhat is more useful is perhaps an understanding of just how really huge an amount of energy that makes for even a small amount of mass. This is the reason why nuclear reactions (which convert mass into energy) are so energetic by comparison to chemical reactions (in which mass is more or less conserved).

ITS [E=MC^2] - THE CONSERVATION OF MATTER AS ENERGY.. IT MEANS IF WE PUSH AN OBJECTS WITH A SPEED OF SQUARE OF SPEED OF LIGHT THEN THE ENERGY PRODUCED IN THE COVERAGE OF THE DISTANCE WITHOUT RETARDING OF 1 GM OF ANY MATTER OF DENSITY ABOVE 5GM/CM^3 WILL BE EQUAL TO THE ENERGY PRODUCED BY 10000KG OF U235 USED IN NUCLEAR REACTOR...

Curiouscat is way kewl.....good answer on her part.\n\nE = mc^2 has been proven valid over and over again. Altho, in science, everything is theory, because someone may come along and find a flaw or correction.\n\nHowever up the present, this equation is rock solid.

E=MC2 doesn't talk about radiation.  It is about energy.  Nuclear bombs and nuclear reactors work off of the same principle.  Just in nuclear reactors, the reaction is controlled and made safe, and in bombs, the energy is released all at once.  When an atom is "split", the total mass of the origional atom and the neutron that splits it is more than the pieces that it breaks into.  That difference becomes heat energy, and the E=MC2 tells you how much energy.  The radiation that everyone associates with it comes before and after the nuclear reaction, when the nuclear fuel and daughter products (the pieces the atom split into) decay and emit various forms of radiation, depending on what is decaying.  E=MC2 doesn't talk about this part of the process, just about the moment the atom actually splits.  To reverse the process and convert energy into mass is mainly theoretical, though it is possible.  Lab conditions have achieved microscopicly small results.  This is the process that the transporters and replicators use on Star Trek.

The equation E=MC2 is the derivation from Einstein's relativity theory. this is not a case of the classic mechanics. this equation explains the value of energy of an atom. \n\nE-> Energy\nM-> mass of the atom\nC-> speed of the light.\n\nin this only speed of the light is constant. the mass differs by frame to frame in accordance to theory of relativity. so the energy of the atoms also differs with frame to frame. but this equation is not fully correct and Lorentz had made corrections to it. \n\nAnybody who can prove this equation as a total wrong thing with strong evidences will be announced as the greatest of the universe..

"Albert Einstein derived the formula based on his 1905 inquiry into the behavior of objects moving at nearly the speed of light. The famous conclusion he drew from this inquiry is that the mass of a body is actually a measure of its energy content. To understand the significance of this relationship, compare the electromagnetic force with the gravitational force. In electromagnetism, energy is contained in the fields (electric and magnetic) associated with the force and not in the charges. In gravitation, the energy is contained in the matter itself. It is not a coincidence that mass bends spacetime, while the charges of the other three fundamental forces do not.\n\n ENERGY = MASS x (SPEED OF LIGHT)^2\n\nAccording to the equation, the maximum amount of energy obtainable from an object is the same as the mass of the object multiplied by the square of the speed of light.\n\nThis equation was used in the development of the atomic bomb. By measuring the mass of different atomic nuclei and subtracting from that number the total mass of the protons and neutrons as they would weigh separately, one can obtain an estimate of the binding energy available within an atomic nucleus. This can be used in estimating the energy released in the nuclear reaction, by comparing the binding energy of the nuclei that enters and exits the reaction.\n\nIt is a little known piece of trivia that Einstein originally wrote the equation in the form dm = L/c² (with an "L", instead of an "E", representing energy, the E being utilised elsewhere in the demonstration to represent energy too)."

The theoretical physics equation E = mc2 states a relationship between energy (E), in whatever form, and mass (m). In this formula, c², the square of the speed of light in vacuum, is the conversion factor required to formally convert from units of mass to units of energy, i.e. the energy per unit mass. In unit specific terms, E (Joules) = M (kilograms) · (299792458 m/s) 2.\n\nThis formula, which was discovered by Albert Einstein, proposes that when a body has a mass (measured at rest), it has a certain (a very large) amount of energy associated with this mass. This is opposed to the Newtonian mechanics, in which a massive body at rest has no kinetic energy, and may or may not have other (relatively small) amounts of internal stored energy (such as chemical or thermal energy), in addition to any potential energy it may have from its position in a field of force. That is why a body's mass, in Einstein's theory, is often called the rest energy of the body. The E of the formula can be seen as the total energy of the body, which is proportional to the mass when the body is at rest.\n\nConversely, a single photon travelling in empty space cannot be considered to have an effective mass, m, according to the above equation. The reason is that such a photon cannot be measured in any way to be at "rest" and the formula above applies only to single particles when they are at rest. Photons are generally considered to be "massless," (i.e., they have no rest mass or invariant mass) even though they have varying amounts of energy.\n\n\nENERGY=MASS x Speed square \n\n\nbtw  check out my website \n\nhttp://oldman.netfirms.com/

Of all time. There is so much choice, but here are 5 and why:\n\n1. Isaac Newton - introduced mathematical formalism to physics and created calculus (he called it fluxions)\n2. James Clerk Maxwell -  gave the first unified explanation of electromagnetism\n3. Ludwig Boltzmann - gave the first mathematical interpretation of the profoundly important second law of thermodynamics, and derived the Botlzmann distribution for gases\n4. Max Planck - founded quantum mechanics\n5. Richard Feynman - developed the first way to handle the fiendish equations of sub nuclear particle physics,  and thereby made quark theory possible\n\nOf the 5 I would pick Feynman as my number 1 - no other physicist has had such profound intuition as to how the universe works. You can still buy his popular science books.

In its original form, the formula is\n\nE^2 = m^2 * c^4 + p^2 * c^2\n\nwhere E is the energy of the particle, m is its rest mass, p is its momentum and c is the speed of light.  If we're only concerned with how much energy is bound up in a certain mass, we say the mass is not moving and its momentum is zero (p = 0).  If this is the case:\n\nE^2 = m^2 * c^4 + (0)^2 * c^2\n\nE^2 = m^2 * c^4\n\nTake the square root of both sides and we get:\n\nE = mc^2\n\nThe full formula, with the momentum term included, works if we want to find the momentum of a photon.  For photons, m=0, so E = pc, or p = E/c.  \n\nEither way, the full form of the mass/energy equivalence formula is useful if something is at rest, or moving with a certain momentum.  E = mc^2  only works if the object is at rest.

overall i'd say e=mc2-einstein of course. his theory is 100 years+ old & has yet tobe proven because science hasn't caught up yet in the modern era & the internet & computers & science universally. immediately the profound effects of what thomas edison has done by far contributed the most. have you ever lost power for more than two days. i never have until last year. let me tell you it was rather bleak. water got bad. food got bad. no fresh air & no a/c.thomas edison is #1. not to say the alexander graham bells, the polio vaccine, the x-ray inventor who died from the process of discovery, & much more have all been significant factors to our well being and yes the nuclear people are included for better & for worse.
