《量子力学揭密》观后感(一)：Quantum effects
（双缝实验）
根据量子力学，我们不能把穿越过狭缝的物体形容为一个实体对象。我们唯一能说的是，这些电子可能具有概率，这种概率波以某种方式穿越两条狭缝，并形成干涉，就如同水波那样，当其达到屏幕时，刚才那具有灵魂般概率的电子，又神秘地变回实体。
Quantum mechanics says this ,we can't describe what's travelling as a physical object.All we can talk about are the chances of where the electron might be.This wave of chance somehow travels through both slits producing interference just like the water wave.Then when it hits the screen,what was just the ghostly possibility of an electron mysterious becomes real.
在某种意义上，当硬币旋转时，它可以同时处于正和反的状态。同样的，电子以概率波的形式，同时穿过两个狭缝。硬币停在了正的状态，只有在幽灵般的概率波到达屏幕之时，才变成了粒子。量子的世界与我们所见到的一切都不相同。
In a sense,as it spins,the coin is both heads and tails.Similarly,the electron's wave of chance passes through both slits,two paths at the same time.Our coin then stops at heads.The ethereal wave of probability hits the screen and only then becomes a particle.The quantum world was unlike anything ever seen before.
玻尔声称，在测量之前，我们无法得知电子的确切位置，还不仅仅只是无法得知电子位置，更奇怪的是电子本身同时处于各处。
ohr was effectively claiming that one can never know where the electron actually is at all until you measure it and it's not just that you don't know where the electron is,it's weirdly as though the electron itself is everywhere at once.
请记住电子是现实世界最普遍，最根本的基石，然而玻尔却说只有通过观测，我们才能使它们的位置变成真实存在。
ear in mind that electrons are among the commonest and most basic building blocks of reality and yet here's Bohr saying that only by looking,do we actually conjure their position into existence.
我们与量子世界之间似乎隔着一道帷幕，而在帷幕的后面，没有确定的实在，只有可能的实在。事情只有在我们拉开帷幕观察时，才变得真实。
It‘s like there's a curtain between us and the quantum world and behind it there is no solid reality...Just the potential for reality.Things only become real when we pull back the curtain and look.
在最基本的量子领域，实在性是不可知的。
At the fundamental quantum level,reality is truly unknown.
两个纠缠光子的特性，不可能在一开始就被决定了(Einstein决定论)，而是在我们测量时才真实存在。
The two entangled photon's properties couldn't have been set from the beginning,but are summoned into existence only when we measure them.
Everything we call real is made of things we cannot call real. —— Niels Bohr
John Bell——
ohr was inconsistent,unclear,wilfully obscure and right.
Einstein was consistent,clear,down-to-earth and wrong.
在这奇妙的量子生物学世界，生命只是一场概率游戏，而规则油量子力学所掌控。
In the fantastic world of quantum biology,life is a game of chance，played by quantum rules.
近些年来，一些极其精准的实验显示，亚原子粒子确实存在纠缠。这就意味着，两者即使在宇宙两端也能瞬间影响着彼此。（阴阳太极）
In recent years,extremely delicate experiments have shown that subatomic particles really are entangled.It means they can subtly and instantaneously influence each other across space.
一对所谓的纠缠电子，每个电子都具有两种可能的状态。除非我测量它们，否则二者不分彼此，但却又能同时区分开来。（硬币/转盘）
An entangled pair of electrons.Here's how it works.Each electron has two possible states.Until I measure it,it's neither one nor the other,but both at the same time.
要打破化学键，需要足够多的能量达到阈值。物理学家们有个有趣的说法“不断努力才能办到事”，即必须达到一个能量阈值。
To break a bond apart,it needs enough energy to get over the barrier.Physicists have a fancy wey of saying"Put in effort to get something done”.They say you have to overcome an energy barrier.
在量子世界中，质子无须达到能量阈值。它们能直接 穿越过去。隧穿效应直击量子世界的奇妙核心。量子既有能量阻断，也能从一个地方隧穿到别处。它们不像日常生活中所见到的实实在在的物体，比如球，它们以古怪的类波行为像外传播，让它们能穿透能量阈值。粒子能在能量阈值的一侧消失，而同时在另一侧出现。在核物理学中，这个现象已被证实。没有量子隧穿效应，连太阳也无法闪耀。
In the quantum world,protons don't have to go over barriers.They can tunnel...straight through.Tunnelling strikes at the very heart of what is most strange about quantum mechanics.A quantum particle can tunnel from one place to another even if it has to pass through an impenetrable barrier.They are not solid objects like balls in our everyday world.They have spread out,fuzzy,wavelike behavior that allows them to leak through an energy barrier.A particle can disappear on one side of the barrier and instantaneous reappear on the other.In nuclear physics,this effect is a proven fact.Without quantum tunnelling,the Sun simply wouldn't shine.
量子隧穿效应最重要的优势是它的速度，发生的极其讯速，比质子先达到阈值的过程快很多。像质子这样的亚原子粒子无时无刻不在发生着这种效应。
The most important advantage of tunnelling is it's speed.It happens incredibly quickly much faster than if protons go OVER the barrier.Subatomic particles like protons do it all the time.
不确定性原理 The uncertainty principle
电子波并不循着某一特定的路径，而是同时循着所有路径。
The exciton wave isn't just going this way or that way,it's following all paths at the same time.
We can't never be certain where new discoveries will take us next.
《量子力学揭密》观后感(二)：Oh, this weird world!
Only the abstrcat from this vedio.
Ep 01: Einstein's Nighmare
the light bulb
If you heated the filament with electricity, it glowed. The relationship between the temperature of the filament and the color of light it produces was still a complete mystery.
Max Planck: why the color of the light changes as the filament gets hotter？ Why is blue so much harder to make than red？ Why is ultraviolet light so hard to make？ → "ultraviolet catastrophe"
a gold leaf electroscope
Charge it up with eletrons that are pushing the two gold leaves apart. First, take the red light and shine it on the metal surface and nothing happens. Even if you increase the brightness of the light still the gold leaves aren't affected. Then try the special blue light, rich in ultraviolet. Immediately, the gold leaves collapse. Light can clearly remove static electric charge from the leaves. But why is ultraviolet light so much better at doing this than red light？ → "photoeletric effect"
These two problems couldn't be explained in that time. Light was a wave. Light can behave in a perfectly commom-sense wavy way. The shadow of one's hand, it's fuzzy round the edges. We understand this as the light hitting the side of one's hand and bending and smearing out slightly, just like water waves around an obstruction. But when it came to the ultraviolet catastrophe and photoelectric effect, the wheels started coming off. If light was a wave, more intensity should konck out more electrons. But that's not what happened. So thinking of light as a wave just wasn't adding up.
In 1905, Albert Einstein came up with a new theory to explain the photoelectric effect and what he suggested was revolutionary and even heretical. He argued that we have to forget all about the idea that light is a wave and think of it instead as a stream of tiny, bullet-like particles. The term he used to describe a particle of light was a quantum. A quantum was a tiny lump of energy. According to Einstein, each particle of red light carried very little energy because red light has a low frequency. So even a very bright red light with many red light particles, can't disloge any electrons from the metal plates. But each individual light particles of the ultraviolet light in the experiment carries more energy. Just a few of them are enough to kock the electrons out of the metal plate. This nifty idea also helped solve Planck's mystery of the light bulb. There was more red than ultraviolet because ultraviolet quanta took so much more energy to make, about 100 times more energy. No wonder there are so few of them.
the nature of reality itself
It began with the discovery of the weird and contradictory wave/particle nature of light.
iels Bohr v.s. Albetr Einstein
Remember from the wave tank experiment where the signature wave only exists because each wave passes through both slits and then its two pieces interfere with each other. But every individual electron, each single particle is passing alone through the slits before it hits the screen. And yet, each single electrons is still contributing to the signature wave pattern. Each electrons has to be behaving like a wave.
Quantum mechanics says this...We can't describe what's travelling as a physical object. All we can talk about are the chances of where the electron might be. This wave of chance somehow travels through both slits producing interference just like the water wave. Then when it hits the screen, what was just the ghostly possibility of an electron mysteriously becomes real.
If I spin this coin... Then all the time it's spinning, it's a blur, I can't tell if it's heads or tails, but if I stop it, I force it to decide and it's heads. So before, it was sort of not heads or tails but a mixture of both. But as soon as I stopped it, I've forced it to make up its mind. This is what Bohr and his supporters claimed was happening with our electrons. He was effectively claiming that one can never know where the electron actually is at all until you measure it. And it's not just that you don't know where the electron is, it's weirdly as though the electron itself is everywhere at once. → the Copenhagen interpretation
ut Eintein thought there should be a better underlying theory. At the heart of the Einstein's argument was an aspect of quantum mechanics called entanglement.
quot;Spooky action at a distance"
ohr's cions, which only become real when we look at that and then magically communicate to each other, or Eintein's gloves, which are hidden from us, but are definitely left or right from the beginning？
In the early 1960s, John Bell decided to try and resolve the crisis at the heart of quantum physics. Bell reduced the idea into a single mathematical equation. p(a c - p(b,a) - p(b,c)≤1
Eintein's version of reality cannot be true. The two entangled photon's properties couldn't have been set from the beginning, but are summoned into existence only when we measure them. Something strange is linking them across space. Something we can't explain or even imagine other than using by mathematics. And weirder, photons do only become real when we observe them.
Ep 02: Let There Be Life
The Quantum Robin
How birds navigated with such accuracy？
Tiny variations in the Earth's magnetic field change the way electrons in the robin's eye are entangled and that's just enough to trigger her compass. If the massage changes, the chemical reaction tips a different way, changing the robin's compass reading. The robin is navigating by "Spooky" Quantum entanglement.
The Quantum Nose
The conventional theory that goes back to the 1950s, say that the scent molecule has a particular shape that allows it to fit in to the receptor molecules in our nose. In fact, it's called the lock and key mechanism. With the strong shape, it won't fit into the receptor. But with the right shape, it fits into the receptor, triggering that unique smell sensation. Different receptors are wired to different parts of our brains. But the lock and key theory has always had a problem.
oth benzaldehyde and cyanide have the same smell, but these molecules are both very different shapes, so the lock and key mechaism, as an explanation for how we smell, can' be the whole story.
The bizarre new quantum theory of smell is all about vibrating bonds. A particluar molecule will vibrate at a particular frequency. The two molecules have different shapes, but their chemical bonds just happen to vibrate at the same frequency. Different vibrations mean different smells.
The Quantum Frog
In metamorphosis, it's enzymes that dismantle the tadpole's tail. And that means breaking down an incredibly tough protein called collagen. But how do enzymes break chemcial bonds apart so incredibly fast？
To break bonds apart, it needs enough energy to get over the barrier. But this is where protons turn into ghosts. In the quantum world, protons don't have to go over barriers. They can tunnel straight through it. Tunnelling strikes at the very heart of what is most strange about quantum mechanics. A quantum particle can tunnel from one place to another even it has to pass through an impenetrable barrier. They are not solid objects like balls in our everyday world. They have spread out , fuzzy, wavelike behavior that allows them to leak through the energy barrier.
The most important advantage of tunnelling is its speed. It happens incredibly quickly, much faster than if protons go over the barrier. Quantum tunnelling turns strong knots into weak ones. So in the tadpole, the entire collagen scafford breaks apart easily.
The Quantum Tree
During the process of photosynthesis, when the proton hit the cell, it knocks an elecrton out of a middle of a chlorophyll molecule. This creates a tiny packet of energy called an exciton. The exciton then bounces its way through a forest of chlorophyll molecules until it reaches what is called the reaction centre. Now, that is where its energy is used to drive chemical processes that create the all-important biomolecules of life. The problem is, the exciton needs to find its way to the reaction centre in the first place.
The solution is that plants obey the most famous law in all of quantum mechanics, the uncertainty principle. It says you can never be certain that the exciton is in one specific place. Instead, it behaves like a quantum wave, smearing itself out across the cell. The exiton doesn't simply move from A to B. It's heading in every direction at the same time. The exciton wave isn't just going this way or that way, it's following all paths at the same time. That's what gives it such incredible efficiency.
《量子力学揭密》观后感(三)：伊拉克秃子带您走近量子生物学
可能因为本片的名字问题以及豆瓣简介不够完整的关系，出现了一些轻率的负面评价。
本片的主旨在第2集，讲的是关于量子生物学的内容，第1集是为第2集作背景知识准备的。第1集的量子力学内容看起来确实非常单薄，但向观众强调了量子世界的奇异性，用一些非常形象的比喻讲解了量子纠缠等微观粒子世界的现象，为第2集进入量子生物学作了铺垫；另外，第2集也有关于量子隧穿效应的内容。
以下我总结了 第2集 量子生物学 的主要内容，供有兴趣的朋友看前参考：
1.量子知更鸟 The Quantum Robin
一般认为的知更鸟靠磁场导航的现象，其实际原理与量子纠缠有关。
2.量子鼻 The Quantum Nose
以前人们所认识的嗅觉的生化原理其实并不完善，嗅觉的实质还与气味物质分子键的振动频率有关（所以实际上嗅觉与听觉、视觉有相似之处）。
3.量子蛙 The Quantum Frog
动物界的变态 —— 以蝌蚪到青蛙的转变为例（个人觉得昆虫的变态更典型而神奇）—— 与酶有关，而酶的强大作用则来自量子隧穿效应。
4.量子树 The Quantum Tree
光合作用机制之所以能够达到极高的能量转化效率，是因为光合作用中的激子具有波动性，其行为遵循量子力学的不确定性原理。
5.量子蜗牛 The Quantum Snail
生物演化的根基：基因突变，本身就可能与量子现象有关（组成DNA链键的质子发生隧穿现象）
—— 真实的量子效应一直在大自然中发生着，而量子生物学的篇章才刚刚开启。

《量子力学揭密》观后感(四)：How real the reality is?
How real the reality is？
看了上半集，跟赛斯讲的桌子的例子联系起来，而且仿佛更清楚了。我们看见桌子就在那，但我们只是在这个频率上看到它，它还有无数频率，在其他层次出现。就像节目里讲的，我们无法知道幕后的真实面目，直到我们拉开帷幕。我们的意识，拉开帷幕，把想要带进来观察的对象带进来。
量子力学，越来越吸引我早点去学习！光子具有波的特质，一个光子居然以一种无处不在的形态传播，当被选择的时候又回到一个光子。能不能引申为意识有无限多可能性，只有聚焦观察它的某一种可能的时候，才把它拉进现实里来，成为我们看到的事实？其实其他的可能一直在那，时间和事件并不是我们想象的那样。还有无数的我，犹如这无尽的可能？
我们灵魂的单位，是不是仿佛同时在转的一些硬币，他们同时发生所以互相感应，而现在的我，是否只是其中被观察到的其中一种结果？
“意识是独立于人体的存在”，希望这一个事实早点普及。下一次人类革命，将是一场意识的革命。人类对意识和能量，将有翻天覆地，前所未有的认识。
《量子力学揭密》观后感(五)：量子力学很迷人
量子力学最迷人的地方之一是：
物质的不同，不在于密度、质量，也不在于构成元素的电子数量和旋转轨迹，而在于能量的组成不同。。。
另一迷人的地方是：
量子力学之所以很多地方难以相像和描绘，不在于其复杂性，而是空间维度的不同：低维度的生物见不到高维度空间生物及物质的全貌。。。
还有一个，即薛定谔理论的深化：生与死、过去与未来在同一时刻同时存在。。。
更凶猛的是：当叠加态和坍缩系数可控时，我们所处的地球，乃至宇宙，乃至整个三维度世界，可以1秒间毁灭，再1秒间重建！
这中间，非当事人可以全然无知晓。。。
本片片头前五分钟不错，后面讲述的过于基础，尤其是在光的波粒二重性上纠结太长。
估计两集只能很浅泛的谈谈量子力学至目前的发展历史而已。
《量子力学揭密》观后感(六)：笔记
1of2.Einsteins.Nightmare
量子力学起源于德国，启发于灯泡。
光为什么是波：1 光照下手指影子边缘模糊。2 水泡内彩色波纹。
光是分散在时空的能量的波纹。
但非常亮的红光不能影响电子运动，弱弱的紫外线可以，不同于水波性质。故光是种波有点讲不通。
hotoelectric effect 光电效应
爱因斯坦用粒子性描述光子，是为量子，量子是一小堆能量。这解决了光电效应，因为红光粒子低频低能量，作用不了电子。蓝光可以，紫外线更可以。“紫外线灾难”解决了。
现代科学开始了。
1922
I might get into trouble for saying this,I would argue that the upheaval（剧变） that take place in physics at this time would eclipse（使暗淡） them all.
them是指欧洲的文化历史演变，
《尤利西斯》是爱尔兰意识流文学作家詹姆斯·乔伊斯于1922年出版的长篇小说。
斯特拉文斯基（lgor Feodro-ovich Stravinsky,1882－1971） （Igor Feodorovich Stravinsky 伊戈尔·费奥多罗维奇·斯特拉文斯基，1882－1971）是美籍俄罗斯作曲家。
1922是他最得意之时。
卓别林发行了第一部正式电影。
奥斯曼帝国灭亡。（现在的土耳其）
欧洲仍在从一战后恢复中，数百万人死掉。俄国新生communist。美国出口爵士乐。
光的波粒二相性引发科学争论，演变成现实性质争论。
黑白条实验：多个电子经过slits（狭缝）和一个电子多次经过，结果一样。
一个电子同时经过两个狭缝（波性）。类比：硬币在转过程中正反共存。然后落在屏幕上呈粒性。
Copenhagen interpretation 哥本哈根解释
an interpretation of quantum mechanics developed by Niels Bohr and his colleagues at the University of Copenhagen, based on the concept of wave–particle duality and the idea that the observation influences the result of an experiment.
爱因斯坦不喜欢这，问：does the moon cease to exist when I don't look at it.
这一边说：现实只有在看它的时候才是真实的。
纠缠电子对争论，类比 1 两个硬币，后决定正反 2 一副手套，左右隐藏，先决定。
1930s
应用：半导体，电子时代。激光，传达革新。原子能。
hut up and calculate. 忽视哲学，忽视爱因斯坦。
1960s
John Bell 裁判
类比：和量子赌徒玩牌，猜同色或异色，每次都输，甚至发完牌后再猜也全输。那个不等式不懂。
1970s
嬉皮好量子。
纠缠粒子对：由同一事件生成的一对粒子。
实验：激光，光子对，猜polarization（偏振，不懂），四次后得出结果大于2。结论：光子只有在测量（理论上？）时，观察（和测量是一个意思吗？）时才存在。
All these 50 years of conscious brooding have brought me no nearer to the question - what are light quanta？
Albert Einstein 1879-1955
ow
英国最大的什么机构的x射线是医院的百万倍。纠缠态应用：不能破的电脑安全，超快传达，超快电脑。
2of2.Let.There.be.Life
鸟，量子纠缠（传达信息速度可比光速快，无空间限制），导航。一个光子射入鸟眼，引起化学活动，生成一对电子，靠近赤道时两电子类比成同色（被搞糊涂了），靠近极地时类比成异色。
鼻子，嗅觉不同于别的觉，1 气味能触动记忆和情绪，直联内在意识。2 听觉视觉探测波，嗅觉探测粒子和化学分子。
嗅觉是关于气味分子的振动，类比弹吉他，吉他手是参与嗅觉的电子。电子粒引发气味分子波，后半部分像听觉，不同气味不同波频。
蝌蚪变形成蛙，酶，快速破坏后重组，类比为什么快，光子能穿墙，穿能量电池，如果不能，星不闪。
as a nuclear physicist, quantum tunnelling(量子穿隧效应，因：放射性衰变，在星内部进行) is my bread and butter.
化学键基本上是绳子上的结，穿隧解开结，快速的。
光合作用，这小段里注意到了配乐，时而磅礴时而幽宛。
exciton 激子，光子触发的电子。激子找反应中心看上去效率很低。
The solution is that plants obey the most famous law in all the quantum mechanics... the uncertainty priciple
喜欢这样的解说句式，这在太阳系的奇迹等的解说人Brain那里是听不到的，平板直诉，让人昏昏欲快进，题外话。
激子同时朝不同方向呈波型探得最佳路线去递送能量。
The ultramodern（extremely modern）science of quantum mechanics is an ancient fact of life.
量子演化，达尔文说，演化依靠某一物种的多样性。
here in laboratory, I'm planning a new analysis of the most cerebrated molecule in science... deoxyribonucleic acid, or DNA.
又见这样的句式，再配上悠远的背景乐，谁不想了解后事如何，1953年发现的。
基因突变，类比拼图，红配绿，蓝配黄，拼图的叉子状连接带是质子，蓝质子能从蓝跳到黄，如果两条链分开，拥有蓝质子的黄拼图只能配绿。
证明quantum tunnelling对生物的作用：细菌在含能和不能两种微粒的水里看其量子突变发生几率。
两个萌点：1 教授和农场人在翩翩慢镜头下仰头试嗅觉 2 教授一路滚红球。

鸟类如何精确导航，欧洲知更鸟，认为动物眼睛内的磁感受器被光子激活时产生一对自由基，每个自由基都有一个不成对电子，这两个电子的自旋是相关的。自由基之间的相互作用和环绕着它们的弱磁场可以引起不同形式的自旋关联，使得动物能够“看到”磁场；嗅觉的产生，锁钥原理（每个分子和嗅觉中的感受器相对应接收），但是事实上不同结构的分子可以有相似的气味，量子力学认为分子中振动的频率或波动性是影响嗅觉的原因，将分子中的氢原子改为其同位素氘原子，改变其振动频率，利用果蝇做嗅觉实验；蝌蚪变态成青蛙上生理结构变化快速的原因（吸收尾巴重构变成青蛙所需的结构），胶原蛋白酶的作用（降低反应活化能，量子隧穿）；植物的光合作用，叶绿体吸收光子，轰击出一个电子和少量能量激子，激子是以量子波的形式到达反应核心驱动化学反应；DNA双螺旋结构，碱基对之间配合键的质子转移，实验重水中的突变率更低。
