Okay that makes sense. Am I correct in my assumption that in the second frame of reference the observer is moving at u_{xB} but not u_{yB}?

You will have to bear with me since I am just a high school student attempting to learn some of this on my own. When they say: u'_{yR}=-u'_{yB} What do they mean and how do they reach this conclusion? I am not seeing it from the diagram. Later in the explanation it states that...

Hi. I was wondering if anyone has a simple derivation of relativistic momentum from lorentz transformation or the relativistic velocity addition formulas. I have attempted to understand this example: http://en.wikibooks.org/wiki/Special_Relativity/Dynamics#Momentum but I have been having...

Hi I was wondering if anyone could help me with this equation. Fdx &= dm c^2 First of all, excuse me for my limited knowledge of calculus, but how exactly can you just use the numerator of a derivative? What do Fdx and dm mean if they are not in respect to anything? Do they simply mean a...
