hijack from Matter waves (split from Photon is massless why?)

You still don't understand what energy is?

 

What a bummer? I wrote it down somewhere

But explaining it without specific geometric variables and conditions doesn't really explain it at all

If only somebody knew math that they never wrote down and didn't forget it?

Now I'm thinking about when I should forget it. I'll remember

 

Laughing like a clown might intimidate the interrogator instead of scaring him in this scenario, depends on what he's asking for. If they want important information, like what light is, maybe I should ask.
