yes as for the cp violations, if there is an answer there must be something at the fundamental level that denotes left/right, I was thinking a somewhat higher level "experiment" they could run to show it :)

I think an analogy of the interwebs would suffice. This can make things even more confusing for some though as they start using pictures and such, but how would you tell the aliens how to assemble the picture on the other side?

how we communicate? if you ignore anti-matter there is a solution to defining left/right (chirality) and its very much based in physics. The question was issued in a quantum physics lecture from richard feynman. But, your forums, your choice

I thought the same thing, and ended up buying a couple papers on what makes life left handed. Pretty cool papers. I figured if we always have a spleen on the left side, SOMETHING is causing that, if you trace it back far enough, you will have it! but as mgb_phys said, it was a choice made...

no, I am saying quantities are not necessary. things exist whether they are labeled or not. stating how many, or how much is just as arbitrary as stating a name I think. We have rules for all of these things, but they are still made up. There is no need for 2 electrons sitting near each...

Im asking do quantities actually exist though? is there anything that denotes 2 electrons? or 3? there are plenty of correlations we don't have a nice little symbol for just because we picked correlations in life to denote functions doesn't mean that the correlations are special in any way...

where does x^4 exist? the americas exist sure, but x^4 is simply a correlation we made up. a pattern our pattern finding brains found. we like to find patterns even when there are none, its what we are built to do. what about 2 electrons make them 2 being close to each other? referancing...

im not sure how one goes about discovering math, you said "roots of an x^4" but that implys that x^4 is something that actually exists. there are much more complicated relations that exist in nature, that we just use more and more math to describe, why couldn't we have made one of those...

this was always a fun question I've had with myself. would math exist without humans? sure the core concepts behind math would exist, but those concepts are made up by us. I don't think math would exist. I think we use it as a way of conveying, interpriting and modifying "quantities" we...

right, but even what we call logic has a rule set we defined to it. Does addition actually exist, or is it a convenient construct we use to keep track of things? but that's neither here nor there :) </hijack>

are you expecting Ma=Ma ? the whole purpose of the equation is to show the relation between things so in this situation the force of something can be calculated based on its mass and acceleration, and it just so happens that the interaction between mass and acceleration works out to be best...

you sound as if you already know/knew the answer? :) I don't know if these forums have a way of hiding info (spoiler tags or something) but in case this has not been posted here, and people have no seen it, Itd be cool to let this sit for a bit for people to think about. I know I had a...

Not sure if this has been asked here (searched but couldn't find anything), but I thought this was an awesome question (heard in a feynman lecture) If you were communicating with an alien race, with no visual lines of communication (only audio) how would you explain left and right, so that it...

Ok, I am definatly going to do some more reading. Some quick questions though, as we got a bit side-tracked with my lack of knowledge and excitement that someone would sit down and explain this stuff to me :) as of now, am I correct in chalking a particles lack of position and velocity to...

dang lol I guess I am wondering if there is a difference between finding something out, and knowing something. Im having a hard time understanding how you cannot know a particles position and velocity. I understand how it could be impossible/impracticle to find this out. In reading...
