What is the exact meaning of 'Mc~' labeling?
I think it's a take of on McDonalds....generic sorta thing..but I've never seen Grey's Anatomy.
May I ask what is the meaning of E=mc2 its literal meaning too?
E=MC2 means energy equals mass times the speed of light squared. It applies to nuclear reactions because it disproves the Law of Conservation of Matter, which states neither mass nor energy can be destroyed. In nuclear reactions mass can be converted into energy and vis versa, proven by Einstein's equation, thus causing the Law of Conservation of Matter to be re-written as neither mass nor energy can be destroyed in a chemical reaction. This was an amazing breakthrough for the scientific world as we came into the nuclear age.
What exactly is the meaning of E=mc²?
You may have heard it referred to as mass energy equivalence?The E stands for energy, the m for mass, and the c for the speed of light (approximately 300,000 kilometers per second).What it means is that there is a sense in which mass and energy are the same thing. There are ways to convert from one to the other, and vice-versa. It also means that the amount of energy in even a very small amount of mass is enormous. This is why nuclear and thermonuclear weapons are so powerful: they convert a tiny bit of mass into energy, resulting in a massive explosion. (Orders of magnitude greater than any chemical explosions.)This is also how the Sun is able to continue emit so much energy (in the form of heat, light, and particles streaming away from it at high speeds) for so long (maybe 10 billion years or so).(An extreme closeup of a sunspot.)(This is the planet Venus transiting the Sun (assuming the tag is right), Venus is about the size of Earth, and the Sun is still in the distant background, tens of millions of miles behind Venus.)This is also why nuclear power is so much more efficient than coal, solar, wind, hydroelectric, and all other forms of power (uranium has about a million times as much energy in it as coal does). Both fission and fusion (whether bombs or power or the Sun) involve converting a little bit of mass into energy (and actually none of the matter is really converted into energy, just the forces binding the matter together, in fission the nuclei split into smaller nuclei, in fusion small nuclei stick together to form larger nuclei—it is the bonds inside the nucleus that account for the changes in mass).
Who said E=mc2 and what does it mean?
The first part of the question is more obvious; It was Albert Einstein, a great theoretical physicist who derived this relation.Now the second part of the question is something important.What does E=m*c^2 convey to us??Does it mean “Energy is equal to mass multiplied by the speed of light squared” alone?Or does it help us to convert units of mass to units of energy.Or even more???Some facts about this relation: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.Mass–energy equivalence arose originally from special relativity as a paradox described by Henri Poincaré.In simple terms, the equation represents the correlation of energy to matter: essentially, energy and matter are but two different forms of the same thing.Few mind blowing things about this equation areA 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. Rest mass and rest energy are equivalent and remain proportional to each other. Thus, each body of rest mass m possesses m*c^2 of “rest energy.Stars like the Sun shine from the energy released from the rest energy of hydrogen atoms that are fused to form helium.In physical theories prior to that of special relativity, mass and energy were viewed as distinct entities. This equation expresses the fact that mass and energy are the same physical entity and can be changed into each other.It says that “If a body gives out Energy equal to E then it’s mass decreases by E/c^2”.Can we realize this mass-energy equivalence?? Sadly the answer is “NO”.For example, if a 1 kilogram gold bar absorbs enough energy to heat it up by 10 degrees Celsius, the mass of the gold bar would actually increase! But only by a tiny amount: 0.000000000000014 kilograms. Conversely, if the bar radiates heat to cool off by the same amount, its mass will decrease by the same tiny fraction.Reference:How to Understand E=mc2http://www.livescience.com/45714...
Can you Explain what the equation E=mc2 means?
This is Einsteins theory of relativity where he realized Matter can be turned into energy, and energy into matter. In this equation; E = energy (measured in joules, J) m = mass (measured in kilograms, Kg) c = the speed of light (measured in metres per second) It means that mass and energy are basically the same thing, in a around about way, mass can be converted to energy and energy can become mass. they are relative to each other. uou can find more details at http://www.aip.org/history/einstein/voic...
Is Big Bang Theory Explained By E=MC2?
I can't comprehend how a spot tinier then an atom explodes to create all the celestial bodies that we have in the universe. Is it safe to assume that this infinitely small spot had infinite energy (E) which when it exploded created mass (M). Is that kind of how Einstein's formula comes into play with the Big Bang?
E=mc2 in plain English...?
I've heard people say several times that squares mean "per second per second". So in plain English, is E=mc2 saying, "The energy of something equals its mass times the speed of light per second per second"? In other words, if the mass of Uranium-235 is roughly 235 nucleons (according to the periodic table), is E=mc2 saying that "the energy contained in one atom of Uranium-235, is equivalent to 235 X 299,792,458 meters per second per second? If so, what does that final number refer to? Joules? And what would the final number actually be? Per second per second means that something is building up speed, and I'm unclear on what the starting speed would be and for how long that speed would have been building up before it's detonated. I think the reason why this question can be confusing is because, even though it refers to the energy contained within all mass, most people associate E=mc2 with the atom bomb. When physicists had to approximate the energy that would be released by the bomb, they asked "how much uranium are we detonating today?", and then they plugged that amount into the equation and said, "alright, then it will release this many joules." So I'm just really curious as to how they arrived at that final number of "energy", when E=mc2 seems to be talking about speed. If someone could demonstrate by plugging some real-life input numbers into the formula and then coherently explaining what the output numbers represent, I'd hugely appreciate it.
What is the significance of Einstein's equation, [math]E = mc^{2} [/math]?
E here is energy, m is mass, c is the speed of light. So energy = mass times the speed of light squared. This is only true in suitable units, (otherwise you need an extra constant in there), such as joules for energy, kilograms for mass, and metres per second for the speed of light. This equation tells us that a very small amount of mass can be converted to what we'd consider a huge amount of energy. An atomic bomb is an example of the significance of this ... but in an atomic bomb, only a very tiny fraction of its overall mass is actually converted into energy.Einstein derived this formula by carefully considering how we measure distance and time; from this he predicted that an object would gain very slightly in mass as it gets faster and faster. Einstein regarded it only as a theoretical fact, and didn't regard it as being particularly useful (it seems) until sometime later Leó Szilárd realised that an atom undergoing nuclear disintegration and releasing a very tiny amount of its mass in the form of energy, could start a chain reaction under suitable circumstances.Now we know that this is how the Sun generates energy, gradually getting very slightly lighter and throwing out huge amounts of energy in the process.It's also true that a huge amount of energy can create a small amount of matter; enough concentrated energy will generate matter and antimatter. If these two aren't quickly separated, they will turn back into pure energy.
