Mind=Blown

E=mc^2 may be the most famous equation in the world, but you may not know that it doesn't tell the whole story. It just describes objects that have mass and aren't moving. The FULL equation is:

E^2=(mc^2)^2+(pc)^2

Watch the video for full details on how this makes sense with diagrams and visual aids. You're welcome for this mind-blam!-.

Yeah, that's way too much for me to take in.

I really don't understand why I have a signature.

It seemed fine until triangles got involved.

Sometimes, I dream about cheese.

Looks like Alberto Eansteen is gonna 'afta get mathmagical lessons!

Think of it like a right triangle: as your momentum decreases, Energy becomes dependent on how much mass you have. As you lose mass, Energy becomes dependent on how much momentum you have. This explains why massless particles can travel the speed of light, yet particles with mass can only get really close to the speed of light.

Studies show that men think about sex every 7 seconds. I do my best to eat hotdogs in under 6, just so things don't get weird.

Please allow me to introduce Myself
I'm a man of wealth and taste
I've been around for a long, long year
Stole many a man's soul and faith

Sure, why not complicate it more. It's not like I understood it to begin with.

Where my science majors at? Or anyone who has taken a high school physics class?

  • 12.01.2012 4:00 PM PDT

Yea, I learned that a few years ago.

I'm your biggest fan!

Do massless particles actually not have mass? Or is it just that their mass is negligible? I thought particles, by definition, had mass.

Everything is interesting if you go into it deeply enough.

Not so much incomplete as it is a special case.

Yea, they actually don't have mass.

You, I don't like you.

Ugh, my friend watched that and acts like he's a genius, telling everybody and their grandmother about it.

Then how the hell do they have momentum?

Seen that video awhile ago. MinutePhysics is a pretty cool channel.

Of course it's old news; how many average people know about it though?

MinutePhysics is a really cool channel. I would recommend watching more videos of his anytime. It's fun to learn about the quirks and quarks of science.

Without The Flood, I wouldn't know what an opinion is.

Apparently very few people in The Flood have taken high school physics.

Regardless of your mind not being blown, it is very interesting that the extended version of the equation isn't taught in high school. I surprised that people who are much older than college level students don't understand this.
