E=mc2 

This guy is a great teacher.. He has very depictive visual aids in his power point.

Great enthusiasm, energy, charisma, and ability to make hard stuff easier to understand. Thank you.

Thanks you very much Mr.m Hitoshi! Absolutely loved it"

Well done Prof. Hitoshi Murayama!!! BRAVO!!!

Thanks for the great in-depth explanation.

Thanks you very much Mr.m Hitoshi! Absolutely loved it" You are great!

This is as enjoyable a scientific lecture as I've ever seen. Very well done and informative.

What an enthusiastic bloke. I like this lecture.

This was the best explanation of theories in physics from classical to present.

Thanks for taking us behind the scenes on such an important topic

A great teacher I find myself speculating the building blocks of mass now :) peace

How could one dislike this? A great presentation!

Good review of mass-energy and some cosmology...A question: What happens to all the light and energy that the stars and galaxies have been pouring into space since the big bang? Do they hit a brick wall at the edge of the universe or they just go on and on and on?

We need more teachers like Hitoshi Thubs up. great vid.

Great detail

I have lots of surprises for our human kind, how life formed start from scratch, how energy turned into life form.

Great leacture....

Thank you for the informative lecture. You are an excellent teacher.

I hope you had chance to see my last video clips, I try to slow down as much as possible to explain things clearly. Atoms will grow size wise only if they pick up more mass particles other wise they will stay the same size or decay. Mass supplies the energy to a atom, atoms consume the energy within certain rate, if supply exceeds demand another electron will formed. We know well molecules don't move in higher speed, their movement wont exceed more than 10 mile an hours within atmosphere.

You will never yawn when attending vivid classes like this one

wonderful man ...!

Mass is formed within E2 forming inward spherical wave fronts multiplying time dilation at right+angles compressing energy resonance input+0/1-output interference or compressing+4-0-4+-decompressing expanding wave fronts repels like charged time dilating inertial ref-frames absorbing and emitting the density of two previous levels spiralling outward Fibonacci sequence of broken symmetry seen everywhere in nature continuously the outward momentum of light C2 forms the inward force called gravity.

You sir explain things very well!

i think i got lot of knowledge by this video thanks...

good speech..thanx

The actual equation is m=E/c^2. E is constant with a particle unless accelerated by an outside force so it's a given. c is a given. Your perception of c is determined by the energy/mass density of the medium it travels through. The higher the density, the slower your perception of c is, but it's still c since all velocities are actually in terms of c. Energy isn't determined by the mass, mass is determined by the energy. People keep looking for dark matter not realizing that photons have mass. If you realize this, you will understand mass very well. The fact that you can't measure it doesn't mean it's not there. Oh BTW neutrinos are actually very high energy gravitons. They travel at c with 0 rest mass. The only reason you don't think it's moving at c is because detectors are built underground so they seem to be going slower than c because of the density of the matter they are travelling through. Neutrinos are created by accelerating a massive particle just as photons are created by accelerating a charged particle. The "area of effect" of a neutrino is determined the same way as a photon meaning the higher the energy, the smaller it is. Only accelerating an electron into or out of a proton or a neutron will produce a graviton with enough energy to be detected.

That make's more sense because all objects have their own time line of broken symmetry relative to their own energy or mass at the centre of their own ref-frame's. The apple composes itself from photosynthesis from the light and low potential gases, into high potential liquids and solids and after the work has been done radiation is the normal death principle as the apple decomposes itself back into gases and vapours from the inward absorption and outward emission of electromagnetic wave front's

@emilynmanaig you can add speed on top of speed, but there is a limit. its the cosmic speed "C" this speed limit happens to be the speed of light. if we try and add speed on to the speed of light it wont work, the speed of light is constant. your question is a valid one though, its hard to know absolute motion or absolute speed, im i dont think we are close to speed "C" at all. all we know is what is relevant to us.

Vibrating wave centres of matter are opposed motion simulating rest and balance now through violent motion compressing E=mc2 decompressing expanding spheres dissipating gravity. Everything is two opposing vortices compressing+4-0-4+-decompressing expanding spheres. Only difference between solids, liquids, gases and plasma E2 is Volume. Outward expansion of EMR repels like charged wave centres absorbing and emitting the density from two previous levels spiralling outward mass dividing gravity C2.

When is not windy calm weather molecules move slowly, things change when is windy. Well my explanations goes how the nature is functioning in the darkness of the space, not the factory flour. For that we have to get even deeper into it see how certain level of energy combine becomes something different.

Worth watching.

Yes I believe the Lorentz symbol for gamma, and Euler's identity is very important for understanding what's going on here. Could we have the inverse cube law because the uncertainty principle is always higher than the Planck's constant?

DharmaxWay, good point well made. I am new to RU-vid as well and I seems all the comments on every video posted degenerate into a nasty slanging match. I think RU-vid is a wonderful idea for sharing information with others and it would be nice to see more amiability amongst its fellow users. Especially to our American friends( I'm English) who seem to get a right old bashing at every turn. Which seems jolly unfair as all the Americans I have met are lovely.

I'm glad to see Long Duk Dong went on to a successful career!

Best speed lesson in physics you can find.

"Even a small explosion is a myriad of many." Our universe is a wave-chain reaction between an infinite amount a three-dimensional +/- charges. These ref-frame's are "wave-front's" concentrially layered like onion's, forming wave-center's, the positron input +0/1- output electron wave-front's compressing+4-0-4+decompressing eXpanding sphere's dissipating gravity, dividing time symmetry, at the same ratio information is being multiplied oscillating +/-mass at expense of gravitational potential.

22:00 what things in a proton or electron are moving so fast ? what thing make them to move the proton or electron n what make them to stay or does those things inside them stop moving when a proton don't move n they move when it move ? if it is like that then what is the thing which is controlling them ? if mass is that how much proton is moving inside the atom and that produce energy what make a living thing to use that energy on right time when they need it ?

@Michel0555 A good example of converting energy into mass is the creation of the universe. Every solid thing you see in the universe is the "residue" of the energy created by the big bang. Stars, planets, galaxies, etc...

E=mc^2 seems to be missing something that E^2=m^2c^4 still has. I guess Dirac saw this. Maybe part of what is missing is found in E=sqrt(m^2)c^2 observing two possible solutions +m and -m for the same value of E, implying gravitational mass and inertial mass are not necessarily sign-equivalent and that GR has no explanation for antimatter, supposed a complete lack of it, and probably gives an excuse to miss seeing antimatter and to go off on matter-based snipe hunts where it's dimly glimpsed..

Have we been mesmerized by the formula "E=mc2"? The only explanation of the c2 (c-squared) part given in this one hour lecture is "just think of c as a very big number." Ok, so really the formula is "E=M times a very big number". Why not restate it like that once and for all and get rid of the confusing concept that somehow the amount of energy produced from mass is directly related to the speed of light squared (which is simply a constant, and may be expressed in any arbitrary units)?

As in (E=ˠM˳C²)∞ the Lorentz contraction of space and time is between the energy and mass. The greater the energy the greater the contraction of space and the slower time will run. Mass will increase relative to this and each ref-frame can be seen as a vortex in space formed by the rate that time flows. C² is light radiating out in all directions forming a sphere that can be squared to form the future probability. The brackets represent the boundary condition of the ref-frame within infinity!

great lecture. pure science but very understandable for nonphysicist like me and no admixture of silly comments like hawking's 'god is not needed or does not exist' conclusion.

yeh ive thought that ever since learning about E=mc2 and i think it pretty much proves things like Hinduism. and the bit he says "and Visa Versa" meaning ENERGY into MASS rather than mass into energy i think you get the awnser to CREATION :). people always say about the big bang in the start there was mass and then people say but where did it come from. thats where!

Excellent!! Great lecture. Just one thing: check your pie charts. They seem to be under wrong numbers!!

Yes very true!!! Only Two Spherical Wave's . .a wave-chain reaction between an infinite amount of three-dimensional ref-frames, or wave-center's concentrially layered like onion's producing the coupling resonances positron input+0/1-output electron wave-front's compressing+4-0-4+decompressing eXpanding sphere's dissipating gravity dividing time symmetry, at the same ratio information is being multiplied by the electrical potential oscillating volume +/-mass at expense of graviational potential.

energy? what do you think happens when you burn something? some is converted into ash some into gas and the rest into ENERGY.

Shouldn't the equal's symbol be two way arrow's?

How much temprature will it take to convert energy in the mass?

Nice guy.

The higgs field interacts with the particles moving through it giving them mass and the higgs boson is also apart of this field.

I imagine all forces formed by E2 a locational spherical inward absorption density 4pi and outward emission density 2pi of electro magnetic wave front's forming antimatter matter annihilation, + and -electric charge and EM-field's, or resonance and now interference as time unfolds from an atom or group of atom's contracting E2 reacting and expanding C2 together forming inward force called gravity. Like rain multiplying volume of a lake increasing exponentially as gravity spills over the edge's.

Suppose the radius of Hoag's galactic ring is largely set by constant quantum gravitational flux from the galactic core at ~60K ly, i.e. close to proton radius times near-limit electrostatic/gravity force between protons, each quantum expressing a quantum-based sinusoidal multiplier, and that all gravity follows the same quantum rule. If one can do that, one can suppose the gravitational quantum is spin 1, exchange of two quanta is a spin 2 effect, and easily kiss curved space-time goodbye.

@cartossin The mass of the supermassive black hole is no where near enough to account for the missing mass.

I'd've thought the E=mc² belonged to M. Curie because of her precision work with radium and polonium and, uranium and thorium-measuring their radioactivity energies-ca late 1890"s... certainly it could have inspired Einstein to formulate it, in-fact it would explain why his Special Theory of Relativity was diagnosed as D-arithmetic, because he'd skipped a proper derivation from Newton for linear dependence and landed on the square-law dependency energy, which Minkowski then worked backward to a familiar mistake we learn in college today.... (Newton was so far ahead of his colleagues that he got lazy and never calculated the mathematical implications of finite light-speed on the perception of space-time, though he recognized Roemer's discovery.)

@CreativiTTTTy actually , he could still be right. The experiment could have a procedure error. It already happened. The experiment is so precise, that any tiny error can causa a big difference. sorry for the bad english

Wonderful presentation. Cdr M Gerald

nice vid

thats soooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooo cool

the man can teach.

Very interesting, but I was lost........although i now kind of understand the formula e=mc2.

I think part of this is a little outdated. (around 31 minutes) As of recently, we now know that the missing mass in a galaxy is the supermassive black hole in the center. This has been proven (at least in our galaxy) by observing the orbit of stars very close to the center of the galaxy with the new corrective optics in the telescope in Hawaii.

@locomotifx Thx ! i am also not pro but i am doing Ph.D on biological clocks and chronobiology but i also have much interest in physics too .

accoring to the equation if u fussion the oxygen(at the un immaginable speed becaus its mass is low u need to increase the velocity much greater than c^2) with silicon then it is possible to get new atoms which is practically not possible ...

me too!!!! i've never learned so much in only 1 hour in my life.... I guess we can call ourselves smart motherfuckers now huh ;)

Could human mathematics be based on the dynamic geometry of the Universe? If we take E=MC² we can see that energy is linked to light. Light will radiate out in every direction at a constant speed forming a sphere therefore we have π in human mathematics. This is a continuous process with the future coming into existence light photon by light photon therefore we can only ever have an approximation of π. This is an invitation to see an artist theory of the physics of ‘time’ as a physical process!

What does a fish know of the water in which it swims

@rajamuttu Unlike fish, most humans only know what they are told.

In regards to the expanding universe, i dont believe in 'infinite source of energy' so i wonder and assume theyve considered that dark energy is converted from dark matter maybe? :s and eventually the acceleration of expansion will stop if this is true

E=mc². E=m=c=∆t.

Particles were never meant to be confused as things, they are nothing more than points of reference for wave phenomenon & dynamics. People can say the colors: red, blue green etc. & use them to refer to very specific frequencies, the same with this nomenclature of particles that has become a science to itself with limited range, scope & understanding inventing new words for previous words & meanings better described by Quantum Theory & Wave Mechanics. Scientists ignore Science.

it does not take a phd to know that the world is full of wimps... nice video anyway, and the guy is amazing. explaining this complex matter in an easy funny way. thank you

हिन्दी में मिल सकती है क्या

@topbluffa1 got me there! ;) not a native english speaker so cut me some slack will ya ">*

@ubercoolist That means Albert E equals MC Squared!!!!!

11:51

Isn't potential energy technicly kinetic energy?'' Same effect...Speed

I kinda like the presentor but the subject matter is exactly why I became a shrink. :)

funny cus im learning this in eight grade, this is just on a larger scale/ concept i guess

Such a simple minded retort.

Explaniton: Albert E, equals MC squared.

[25:40] 'Turning Off the mass of the electron' would have no such effect, as its charge would suck it down into the nucleus, and the Earth too would shrink down to a neutron 'planet', and there'd be no general escaping as he claims.... Nevertheless, if these 'imagination' electrons were to retain their mass-energy 511 keV, converting their rest mass to photonic rather than lose it, they'd shrink their orbits according to their wavelengths to about 2/137th their usual. [48:39] No explanation for why galaxies are not expanding with cosmic space, expansion....

@checthisshitout when you are butning it you use chemistry and also without nerds there wouldn`t be any scientists and no computers and no technology so be greatfull (sorry if I have bad english)

@JarJar88forever nothing can help you understand it.

Where does E= Mc^2 come from? In 1905 Einstein asked: Does the inertia of a body depend upon its energy content? The answer was: Yes, it depends on its energy E= Mc^2 So, Einstein said - E= Mc^2 comes from inertia 2 In 1928 Dirac said - E= Mc^2 comes from vacuum and can be as positive as negative too 3 Sometimes E= Mc^2 can be ‘rest’ particle and sometimes can be ‘active’ and can destroy cities like Hiroshima and Nagasaki Why E= Mc^2 is so strange ? Nobody gives answer

E=mc2 BIG AUDIO DYNAMITE

Why do many people, writing comments after video clips on here, have to be make such nasty comments? I am new to You Tube, I come on to study, and like to look at comments from others, who have also looked at the clip. But, no matter what the subject matter, of the clip, therd are always some really nasty comments, directed at other people, who have left comments. This, seems to be the state of the world now. It isn't cool, to be nice and polite any more.

In sun who store energy which energy keeps earth moving $ planets moves arond sun perfecty

If m=1kg then E is about 9.0×10`´16 J. If mass is zero then E is...

we live in a fucked up world.

good question... idk

thats what she said.....

All mass is NOT created equal therefore it is absolutely certain the equation E+MC^2 is false as stated. That said there is a relationship between mass and energy but it is not that simple. If it was we would be doing fusion with silicon and oxygen...now you tell me...

E=MC2 = 0.111 x 300,000,000 x 300,000,000 = 10,000,000,000,000,000 Joules This is an incredible amount of energy! A Joule is not a large unit of energy ... one Joule is about the energy released when you drop a textbook to the floor. But the amount of energy in 30 grams of hydrogen atoms is equivalent to burning hundreds of thousands of gallons of gasoline!

NIRVANA FOR EVER best band ever

i know. i said MASS = ENERGY. ?

this is the guy who invented nintendo!!

@topbluffa1 i think it pretty much proves things like Hinduism

E=MC2 is more likely E=M2C4+P2C2 ... The equation is wrong. It tells the rest mass, when the mass is still. Not the mass you can get out of it.

a hundred ears (':

cant hear einstein
