Lecture 6 | Modern Physics: Quantum Mechanics (Stanford)

this program is brought to you by Stanford on iTunes you at Stanford University please visit us at itunes dot stanford.edu X they behave oddly I've showed you some interference of light waves when they go through slits and that sort of thing uncertainty principles for particles and a photon is a particle so it shares the uncertainty principle with other particles but perhaps the the really simplest context the…

Mod-01 Lec-01 Basic Quantum Mechanics I: Wave Particle Duality

Mod-01 Lec-01 Basic Quantum Mechanics I: Wave Particle Duality

we will be discussing the basic concepts in quantum mechanics and as we all know the concept of quantum mechanics started with the wave particle duality so we will first discuss the phenomenon of wave particle duality and give after that a heuristic derivation of the Schrodinger equation a major portion of nonrelativistic quantum mechanics is just the solution of the Schrodinger equation for different potentials that we plan to…

Volvo Trucks – How the new D13TC engine cuts fuel consumption while increasing power

Volvo Trucks - How the new D13TC engine cuts fuel consumption while increasing power

Ovako radi novi motor D13TC. Zrak struji kroz motori ulazi u cilindar. Brizgaljke ubrizgavaju gorivou komprimirani zrak, i tako izazivaju paljenje. Patentirana komora za sagorijevanjevalovite površine vodi plamennazad do centra cilindra za koncentrisano i efikasno sagorijevanje. Vrući izduvni gasovi izlaze iz cilindra, kroz turbo i izduvni sistem. Višak toplote i pritiskazatim se vraća i iskorištava prekoturbocompound sistema. Ta turbina usmjerava energijuna zamajac koji pokreće radilicu, i daje motoru većiobrtni moment…

Automotive Lock Raking and Wave Key Information

Automotive Lock Raking and Wave Key Information

hello what I have here is a chrysler door lock there's the key bidding for it kind of a tough bidding and here we go you can see that the door lock here only has five wipers on it um in it what I'm going to do is pick it for you just to kind of show you there's not a lot of motive picking videos out there I'm going…

Double Slit Experiment – The Strangeness Of Quantum Mechanics

Double Slit Experiment - The Strangeness Of Quantum Mechanics

we now examine a phenomenon which is absolutely impossible to explain in any classical way and which is at the very heart of quantum mechanics the famous double slit experiment to understand this experiment we first need to see how ordinary particles or little balls of matter act if we shoot small objects such as marbles at a screen containing a single slit we see a pattern form where they…

Quantum Mechanics 2 – Photons

Quantum Mechanics 2 - Photons

welcome to the second video in this series on quantum mechanics in the first video we saw that classical physics failed to explain the relationship between temperature and electromagnetic radiation such as arises in an incandescent light bulb the classical prediction is that radiation intensity will always increase with frequency Planck was able to derive a radiation law that matches what is observed intensity reaches a peak at a certain…

Can Silence Actually Drive You Crazy?

Can Silence Actually Drive You Crazy?

سوف اقوم بالصراخ باعلا صوت ممكن وسأستمر بالصراخ باعلا صوت بينما ادور حول نفسي, وساستمر بذلك حتى ينقطع نفسي ممتاز هل انت مستعد؟ حسناً شكراً كان الامر ممتعاً شكراً المكان الاكثر هدوءاً على وجه الارض, يبدو انه غرفة معدومة الصدى في مينيابوليس هنا في جامعة بي واي يو لديهم غرفتهم الخاصة معدومة الصدى. وتسمى بالاتينية "انا كويك" اي معدم الصدى ويحققون انعدام الصدى من خلال مادة رغوية ملصقة على الحائط…

The Quantum Experiment that Broke Reality | Space Time | PBS Digital Studios

[音乐] 本短篇由 Great Courses Plus 提供 一个非常奇怪的测试结果 那就是单个粒子 的双缝实验 它是一个非常令人惊讶的实验, 它演示了量子世界非常不同于 我们直观感知的宏观世界。 我们的物理直觉。 事实上,它蕴含着我们真实世界里最本质的自然现象 也可以不是物理在总之,至少在任何意义 我们所熟悉的。 [主题音乐] 让我们我们从我们熟悉的认知开始 有一个橡胶小鸭 它在水池里上上下下,导致周期性的波纹 往外传播 在一定距离之外,这些波纹遇到了一个障碍物 这个障碍物有两条细缝 大部分波纹被堵住了,但有部分波纹通过了细缝。 新的波纹会相互重叠 他们产生这种靓丽的纹理 它被称作为 “干扰纹理” 那是因为在某些地方, 从一条缝里出来波浪的波峰与从另外一条缝里出来的波浪的波峰重叠 产生了更高的波峰。 同理,也产生了更深的波谷 我们称之为 ”构造干扰“ 当一个波峰与另一个波谷相遇, 它们相互抵消,水面平坦。 这是 “湮灭干扰” 因此我们获得了波浪与平坦交替的水纹。 任何类型的波浪都会产生与此类似的条纹。 例如,水波、声波 包括光波 这个光的双缝干扰现象首先由 汤玛斯.杨 在 1801 观察到。 一束光线经过两条非常细的细缝 产生了明暗交替的条纹 也就是“构造干扰” 与 ”湮灭干扰“ 当然,我们都知道光其实就是 一种电磁波 对光的这种认识要归功于100年后的麦斯维尔。 因此光是电磁波是不是完美的解释了 这种干扰条纹? 但是,我们也都知道光 是由一组不可分割的 电磁能组成,也就是所谓的 “光子”。 爱因斯坦通过光电效应证明了这个。 但是他的思路来源于 麦克斯布朗可 的 黑体辐射理论的 的量化能量 观看我们的其他短片可以了解这部分的细节。 好。 既然每个光子是一小块光波…
