warm holes and did a bunch more super smart stuff

As for us this morning we made a pbj on

lee We got distracted and forgot to put jelly in

it so yeah we're not quite on his level We've

made a peepee If the amount of mass lost during

a nuclear reaction doubles what happens to the energy released

and hear potential answer double Okay we've been waiting for

this moment We finally get to talk about the world's

most famous equation E equals m c squared who And

yes is the kind of stuff that gets us well

equals m c squared describes how energy and mass are

related to each other Energy equals mass times the speed

of light squared speed of light is a really big

number two hundred ninety nine million seven hundred two thousand

forty Fifty eight meters per second to be precise fast

hopefully square that we could spend a few eons counting

that high with our fingers and toes We have to

take our socks off What does that mean Well it

means that if mass is converted to energy we'll have

a whole lot of energy on our hands Like scary

amounts of energy Kaboom Amounts of energy like that in

a nuclear reaction mass is converted to energy The more

mass that's lost in a reaction the more energy that's

produced waken Think of this equation as e equals the

change in mass times the speed of light square Well

if we double the change in mass we just add

to the coefficient and because we're doubling one side of

the equation We know that the other side has to

double to no The correct answer is deep right there

which just makes sense if we double one side of

an equation and the other side has increased proportionally way

can't be quite a smart Is einstein waken look like 00:02:07.945 --> [endTime] hey baby yeah we're dialing
