E=mc2

012 - E=mc2

In this video Paul Andersen explains how the conservation of mass was replaced with the conservation of mass-energy when it was determined that they are equivalent. This famous equation not only show the mass-energy equivalence but can be used to determine the quantitative amount of energy gained or lost in this conversion. Albert Einstein developed this formula in 1905 while working as a patent clerk.

The best explanation I have seen so far.

[frankstevenson]

That was very helpful, thank you for allowing guidance in science for various generations. Keep on keep on and have a merry and a very jolly day.

(I know this is old but) Fantastic video and explanation! Your voice is clear and engaging, and you clarify the meaning of E=mc2 very well. Subscribed

A big thank you for all of your awesome videos

[MatheusSilva-dragon]

Super helpful! This video has infinite energy!

[SSstyles]

in class I didn't quite get how the binding energy accounted for the seemingly lost mass of a complete atom (as opposed to the sum of its parts) but this tied it all together a bit more smoothly. Perfect timing for my physics final. Thanks.

Thanks for the video :) Very helpful :)

Hat's off to your teaching way Man 😀

There is evidence today from literature which states the law of conservation of energy may not really be supported in time where time is a parameter (Time correction or time correction  relativity). Sean Carroll (Energy is not conserved) in a blog discussed such issues concerning the context of gravitational energy.

This is the best explanation I’ve seen by far. Thank you so much!

[flodde]

I have been looking around for a good and simple explanation for a while now.
And here it is! Thanks :) finally I understand!

Hella true player right here, fat shout out to mr. A for hookin up this knowledge connect tighter than a cork!

By far the largest part of the energy on our Earth is in the atomic nuclei. We can only partially convert this into heat by nuclear fission, but it is enough to secure the energy supply for humanity.

thank u
this is one of our topic in midterm
now i got it ;)

Ai posteri l'ardua sentenza

Albert Einstein: massa = E./c2
Olinto De Pretta: Energia = mc2
Lorenzo Marini : Spirito = mc2:

Sono io che ho ragione nello scrivere la Formula:
In modo esatto ed onesto.

It's a conversion formula,  converting Matter mass to Energy mass.    °E  =  °M  x  ( c^2 )
Converting Matter mass units into Energy mass units.    Like a ºC to ℉ formula, and back. 
Matter mass   =    Energy mass  /   ( maximum speed of Energy mass  ^ 2 )
℉ = ( ºC x 9 / 5 ) + 32,  ºC = 5 / 9 x ( ℉ - 32 ),  0ºC = 32 ℉ ,  the temperature is the same.

 °M = °E ÷  ( c^2 )  ,   °M is Matter mass ,   the °E is Energy mass.   The mass is the same.

I'm a little confused on how the units cancel out, can someone explain?

Have you ever watch wood burn, the flame seems to never touch the wood, it floats on a pillow of air, which is the wood's ether that's released from the charring wood

I am a little bit confused about how a proton gains mass. Does that mean the proton becomes more dense or bigger? This question is probably silly but I can't seem to picture this in my mind. Can someone please help me to understand what is happening to the accelerated proton.

[pioneerwoman]

How can we relate this equation to the law of thermodynamics?
