comment Show quantum entanglement to a classical thinker
This is pretty good answer to the question :) Does that mean there is an experiment which is close to 100% winning? It could be an objection if the required state is not realizable. How can I find that experimental test?

comment Show quantum entanglement to a classical thinker
Thanks! This looks quite promising and I have to study this closer! I read the CHSH inequality, but havent got a deeper grasp on it. When a layman asked me what I'm trying to understand, I knew which way I wanted to answer, but wasn't sure how to frame the CHSH this way.

comment Deriving Statistical Mechanics laws from Quantum Mechanics?
True, that's what I meant by "presuppositions". You can apply the methods of statmech to anything where (micro)states have equal probability. Entropy laws follow from that. You could equally apply statmech to a set of cards or anything abstract.

comment why people choose condense matter physics the most in 2007 and 2008 for their phd? And what are they studying and what is application in this subject?
At university we learned that with logic, proper analysis and error analysis every smart person should arrive at the same conclusions. Why are experiments seem to "proof" completely opposite views at the same time? By "more real world applications" I thought that surely discoveries in more practical sciences like engineering are more often useful?! There were very few usable result in CMP in relation to the amount of papers published? Anyway, I hope this answer provides a complementary view from someone who doesn't regret that he quit the academic path for a reason :)

comment Which new insight did $E=mc^2$ give us?
The moon has simple binding energy to the earth which was way before Einstein. And you could knock out an orbiting object and get energy back. Is binding energy in particular isn't the difference.

comment Which new insight did $E=mc^2$ give us?
You helped me find the answer. In my opinion you just don't get to the point and the "in-depth/fundamental" part was missing. That's as much as I can say. Thanks.

I've found an article to the walking spill problem: pre.aps.org/abstract/PRE/v85/i4/e046117

comment Which new insight did $E=mc^2$ give us?
It's certainly true. Let me try to draw a conclusion which is more the "fundamental insight" part that I was looking for. That splitting nuclei emits energy isn't surprising either due to the known concept of binding energy. But maybe the actual key point is that binding energy can be measure by the gravitational force? The conclusion I see is that kinetic energy can be converted to real particles. Is that the essence?

comment Did they find a new particle with CMP?
Thanks! So it's similar to magnetic monopol discovery. How boring :)

comment Macroscopic laws which haven't been derived from microscopic laws
Very good point! In fact I'm exactly refering to something like "more is different" and asking where such a high level law has been found, which was inaccessible from microscopic ones.
