Simplest Explanation of E=MC² for Beginners | E=mc2 explained

if you ask many of us what is the  most popular scientific equation.   In the world the answer that everyone can say  without hesitation as E=mc2  And we knows that inventor  the genius ‘Albert Einstein’.  But what does it really mean!? Some intelligent peoples explain like this!!   And some others!! It's not mc it is m c, m c  cannot be squared because it is not m and c.  But on the most basic level the equation says,  that energy and mass are interchangeable   they are just different forms of the same thing. Einstein didn't find out this famous equation   in old age as we think. He was  just 26 when he discovered it.  Here's an example of this equation: If you could  turn every one of the atoms in a paper clip into   pure energy leaving no mass, Whatsoever the  paper clip would yield 18 kilo tons of TNT. That's roughly the size of the bomb that  destroyed hiroshima in 1945. On earth,   however there is no practical way to convert a  paperclip or any other object entirely to energy,   It would require temperatures and pressures  greater than those at the core of our sun.   Einstein was not the only one  behind this scientific marvel   behind it is a century of history mixed with the  sweat, blood and love of many geniuses.That’s what   we're going to analyze a little bit now. First we  start with ‘E’.The early 1800s the word ‘energy’ is   surprisingly new when energy was not considered  to be the only creative substance in the universe. they thought, that the heat from the fire  and the rays from the sun were different.One   of the men who took a central role in changing  this whiz michael faraday. A very good apprentice   book binder who had no interest, however in  spending his life binding books as an escape hatch   from poverty in the london of the 1810s though,  it was a job that had one singular advantage   there were plenty of books; and he reads them;  When faraday was 20, a shop visitor offered him   tickets to a series of lectures at the royal  institution. Sir Humphrey davy was speaking   on electricity and on the hidden powers that must  exist behind the surface of our visible universe.   Faraday went and realized he had been granted  a lucky glimpse of a better life than he had   working at the shop. But how could he enter  it he had not been to oxford, or to cambridge.   But he could bind an impressive  looking book faraday had always been   in the habit of taking notes when he could and  he brought back to the shop notes He'd taken   at davey's lectures he wrote them out and inserted  a few drawings of davey's demonstration apparatus   and he made a terrific book which he sent to sir  Humphrey davey.Ddavey replied that he wanted to   meet faraday he liked him finally hired him away  from the binder as a lab assistant. Then faraday   and davey found one mystery thing that was if you  switched on the current in an electric wire any   compass needle put on top of the wire would turn  slightly to side, but no one could explain this   after much research he discovered that a  magnetic field was formed around the wire   at right angles to the current similarly with a  magnet he changed the direction of constant flow   this is the world's first electric motor thus he  established that electrical power and magnetic   force are interrelated thus was born the  new scientific branch of electromagnetism   this is where einstein took advantage of the  fact that energy is something that cannot be   created or destroyed but can change from one  state to another okay now time for m the mass   for a long time the concept of mass had been like  the concept of energy if we want to know about   mass we should back in 1770s antoine lewiser was a  chemist who found something about mass in his lab   he injected steam through an hot iron tube and  on the other hand he collected it and cooled it   it means he performed a chemical reaction that  caused the iron pipe to rust the difference   between the mass of water used for heating and the  mass of water eventually cooled was equal to the   sum of the gas mass released during the chemical  reaction and the increased mass of the iron pipe   in his time there was a hope when a wood is  burned the mass of the substance is permanently   expelled by a substance called phylogeny in  it this is why all scientists believed that   the weight of the excess ash was less than  the weight of the original wood it was then   that lav was a with his tireless work with the  help of his intelligent and loving wife proved   that no matter how much change takes place the  mass of an object does not increase or decrease   the two sides of a chemical equation are  always equal everything is okay energy and   mass are interdependent so they are in the  equation but how did this light get inside   to go very fast is called calaridis in latin  language according to man only light can go fast   three lakh kilometers per second here michael  faraday comes again for a long time he firmly   believed that light like electricity and magnetic  field depended on electromagnetism but he did   not have enough arithmetic knowledge to prove it  mathematically yes he was a very uneducated genius   james clark maxwell a young man who is well  versed in mathematics was joined with faraday   together they generated electricity  from a magnetic field at a certain speed   that speed is the speed of light they proved to  the world through arithmetic that it never changes   now everything is clear but where did square  comes from it means the speed of light must be   multiplied by speed of light.but why? the answer  came from a young french lady named emily duchata   this emily was one of the most  innovative women of the 18th century   from the age of 23 she mastered mathematics  and challenged geniuses such as isaac newton   a moving object has energy according to newton  if a ball travels twice as fast as a similar ball   its energy also will be twice but emily says it  has four times as much energy not only saying   she did prove it with a little experiment she  placed small lead shells on the brittle clay from   a certain height and measured how far it would  penetrate inside only then was it proved that the   energy of the balls dropped on the clay was not  twice their speed but four times it means if we   drop a ball from one meter height onto the clay  that ball penetrates one centimeter inside clay   similarly if we drop same ball from two meters  height that ball should be penetrate two   centimeters according to newton's law but emily's  experiment showed ball penetrated 4 centimeters   now period of einstein einstein knew about energy  mass c and c squared although confused merged   those but he was clear on one thing mass and  energy are interrelated they are both the same   energy is mass mass is energy einstein gained  a very important insight while discussing about   time with his close friend michael this is  where einstein came up with maxwell's idea   if c is a variable number what is the mass of  an object reaching the speed of light it will   definitely increase since the value of c squared  is very very high an object filled with a tiny   mass is sure to have unlimited energy the correct  understanding of this equation is to understand   what is going on in the core of the stars that  we are all made up of those star particles and   that all the energy available to us from the sun  is e equals m c squared.It is also clear that   stars are converting their immeasurable mass into  energy. but, unfortunately a single atomic bomb   led to destruction of millions of  lives .This is e equals m c squared
