Ruby: Print Out Multiple Lines
Command:
$ printf "1,name1,address1\n2,name2,address2" | ruby -e "while status = STDIN.gets do = STDIN.gets do
print status
end"
Result:
1,name1,address1
2,name2,address2
$ printf "1,name1,address1\n2,name2,address2" | ruby -e "while status = STDIN.gets do = STDIN.gets do
print status
end"
Result:
1,name1,address1
2,name2,address2

Leonard Susskind: "ER = EPR" or "What's Behind the Horizons of Black Holes?"
- Correlation (相関)
- ER (Einstein, Rosen)
- EPR (Einstein, Podolsky, Rosen)
- ER is about geometry
- EPR is about quantum entanglement
- EPR paradox (アインシュタイン=ポドルスキー=ローゼンのパラドックス)
- Albert Einstein
- Boris Podolsky
- Nathan Rosen
- They are appearantly nothing to do with each other
- They are actually deeply connected
- Computational complexity
- Qubits
- |↑↓> - |↓↑>
- Bell pair
- Correlation
- Entanglement is a form of correlation
- Coin correlation: You didn't really know everything about the system that you could have known, that in principle could be known
- Low energy radio wave with couple of quanta in it, and those quanta might bounce off the objects and record which one was which without making any difference to the experiment. Classical mechanics is like that.
- Quantum mechanics, when you look at something you cause it to change.
- Peculiar thing about entanglement:
- You know everything about the system that can be known, but you know nothing about either of the constituents. That's the notion of entanglement.
- Entangle states are very special, they do characterize what quantum about quantum mechanics. Almost everything strange about quantum mechanics traces back to entanglement.
- So entanglement is not restricted to small objects. Large scale objects can be entangled.
Even just empty space is entangled |
- In fact even just empty space is entangled.
- |0 0> - |1 1>
- This is the form of entanglement that's there in empty space between parts of space.
- Scale invariant
- Conformal invariant
- Space is zip together by entanglement
- Contiguous
- Adjasant
- Entanglement has another nice feature: monogamy.
- Alice, Bob, and Charlie
- Entanglement is monogamous
- AMPS paradox
- Paradox about black hole and entanglement
- Two entangled black hole
- Conflicts of principle when they are unravel often lead to the biggest advances in understanding of physics.
- Violation of principle of equivalence (等価原理)

Oliver Stone (オリバー・ストーン): AFP: スノーデン伝記映画、自主規制で「死に体」
Oliver Stone |
率直に言うと、大手映画会社すべてに断られた。脚本は良かった。予算も十分だった。キャストも良かった。間違いなく……自主規制のせいだ
背後でNSAのような敵が潜んでいるとは考えていない。だが、自主規制がこの業界における大きな問題であり、数多くの真実にふたをしているのは確かだ
『No』と言っているのは映画会社の社員というより、映画会社を経営する取締役会だ
- Self-censorship (自主規制)
ラベル:
People,
Self-censorship,
