• General/Interdisciplinary -So, time for something fun... People don't realize just how much energy there is locked up in matter. This is what was so amazing about Einstein's equation, E=mc^2. It is simply the correlation of energy to matter (energy equivalence of any given amount of matter). What is each letter in this equation mean?

E is amount of energy measured in Joules.

m is mass measured in kilograms.

c is the speed of light (3.00 × 10^8 m^2/s^2)

I'm going to play with this equation and show you just how much energy you contain inside of yourself (roughly). Bear in mind these aren't exact amounts, nor is this utilizing the derivatives of this equation. This is simply showing the basic function of what Einstein figured out in the equation's basic form...

Let's use me as an example:

1 Josh = 190lbs

1 lbs = 453.6g

So 190lbs × 453.6g/1 lbs = 86,184g

So 1 Josh = 86,184g

86,184g × 1kg/1000g = 86.18kg.

So now that I'm in the right unit of measurement (kg), let's plug the numbers in:

E= (86.18kg)(3.00 × 10^8)^2

E= 7.76 × 10^18 J

That looks like this- 7,760,000,000,000,000,000, or 7.8 septillion joules of energy.

What does that mean, though? How much is that? Let's put it into terms that you can easily quantify:

1 Joule = 2.39 × 10^-13 kilotons of explosive.

Let's convert the energy equivalent of me into kilotons of tnt.

1 Josh = 7.76 × 10^18 J

7.76 ×10^18 J × 2.39 × 10^-13 kT/1 J =

1,854,640 kilotons of explosives.

Let's put that into perspective: The bomb dropped on Nagasaki in Japan was approximately 21 kilotons of explosive. So that means I have 88,316 × more explosive energy in me than the bomb that destroyed an entire city... and that goes for everyone. Below are links further explaining this equation and how it can be used, as well as why it is so important within the scientific community:
