Wonderful lectures by Prof. Adams. Same topics as when I took 8.04, but delivered with such enthusiasm and with memorable analogies. I admire the way in which he defers using the actual names of certain quantum properties, calling them instead hardness, color, smooth and chunky. This gives the students a way to grasp the concepts, without even mentioning confusing terms such as quanta and spin. Greatly enjoyed his quick allusion to the original Star Trek and red shirts in Lecture 1. We all appreciate MIT's generosity and sense of public service in providing these lectures to the world. Years ago some of us paid tuition for them. Now everyone can appreciate the excellent teaching.

Wonder what his lectures are gonna be like after they proved bell right last year.

This guy reminds me of Gilbert Strang, also from MIT, who has online recording of his lectures on Linear Algebra, another topic (like quantum mechanics) I never thought I would get but after the first lectures, Strang made so much sense compared to the other books and materials I tried to understand that I really understood it and to my surprise I stuck with the lectures to the end including doing homework problems from one of Strang’s books. We’ll see how long I make it in this one, this is harder than Linear Algebra, but after the intro lectures I already feel like I understand some of these concepts in a way that many pop science books and videos never achieved.

I'm an undergrad in my final year of my Bachelor of Science, i've almost completed my taste of the Quantum Mechanics i'm gonna get but i love how this guy teaches and will be here until the end!

What Rutherford *actually* said (4:40) was "It was quite the most incredible event that has ever happened to me in my life. It was almost as incredible as if you fired a 15-inch shell at a piece of tissue paper and it came back and hit you". As a Kiwi living and working in England he would have had little interest in 10-pin bowling. He also said "All science is either physics or stamp collecting", with which I heartily concur. Two other favourites: "An alleged scientific discovery has no merit unless it can be explained to a barmaid", and "If your experiment needs statistics, you ought to have done a better experiment".

Exhausted but exhilarated by the entire lecture series so far. Wonderful series, fantastic lecturer wishing I was eighteen and could take the course!!

I have a question regarding the last point about the Bell's Inequality. In the formula, the term N(H, not B) was actually established as meaningless in the first lesson: You can't say anything about the color of 'hard' electrons. So, something happened that we now can do an experiment with hard and not black (white) electrons.

What a great find! This professor is awesome!

Amazing lecturer with total involvement.

Thank you for uploading this great lecture. I am not a physicist, I am a biologist but the lecturers are so well explained that even I can understand it and be intrigued by it. I am just a bit confused with the duality of light and electrons that are actually quanta of energy or single electrons respectively but when they interact with each other they behave as a wave (or at least exhibit some wave like properties). For some reason this duality is presented as counter intuitive but to my mind , and I may be completely wrong, but to my mind what we call a classical wave is a distortion of matter, molecules and zooming in atoms moving in a specific way through space passing energy from one to another. The wave is a movement of matter so it has all the properties mentioned is not localized and it exhibits interference. However a wave needs a material to travel through (again I may be wrong that is what I remember from my physics class) So if wave is a movement or distortion of matter it doesn't have an existence as a photon for example has or as a water molecule, but the molecules for example of the water forming the wave on a pond are distinct molecules of water so in a way every wave can have that duality because the matter through which it moves is made of distinct molecules and atoms but when then move together they create the wave. Pretty much as a human cell is distinct and occupies a single spot in the human body but the multi cellular organism still acts as one distinct organism. Although that would mean that if gravitational waves exist and they distort space time that would mean that space time itself is made of chunks that are distinct but when they interfere with each other they create the space time, much like atoms create molecules and molecules create elements etc. I may have it wrong. I would appreciate any suggestions.

@KK-fv5bs

2 жыл бұрын

I would like to correct you over there. Waves, do not need a medium to travel. MECHANICAL Waves, do. Mechanical Waves appear as distortion of matter. Water waves are mechanical waves, in essence, that they have literal atoms or molecules executing an SHM motion so that the wave exists. However this is not the case with Light. Light, is an electromagnetic wave. It doesn't require a medium of matter. Now one may wonder what is, in fact, an Electromagnetic Wave? Well, I won't be restating Maxwell's Equations, but I will just say that it's the oscillating Electric Field and Magnetic Field at each point. At any point, the Magnitude and Direction of Electric and Magnetic Fields are such that plotting them against time, gives a sinusoidal wave on the graph, just like SHM of particles. So these "oscillating" electric and magnetic fields are analogous to oscillating water molecules in a water wave. So, if there is a wave travelling, it doesn't mean there needs to exist some particle or a chunk. Electrons, and in fact all matter have a wave property to them, which are called Matter Waves. As the professor explains too, the electron is not literally a wave, or a particle. it's in 'superposition' of both, in essence that it exhibits different kinds of properties in different phenomena. When you look at an atom, electrons behave like standing waves inside the atom, with a certain wavelength. When you look at electrons in a CRT, it displays particle phenomena. Visualising it is, almost impossible. It is the way it is, that is nature (as far as we have discovered).

Hey; I am super new to physics and quantum. I have picked it all up pretty quickly, I love that it's the part that was always missing for me in classical physics taught in school. The beautiful degree of randomness is now explained so simply. In the last 6 months, I have bought and binge read range of books on physics, thermodynamics, statistical thermodynamics, information theory, graph theory, Bells to name a few, it's much more than my wallet is comfortable to admit. As it's all pretty self-taught on my part and has been more of a covid hobby than anything else. Does anyone have any great resources on the physics notation that could aid my learning process? It's my main weakness as I understand how and why to rearrange them, but yet the notation/symbols I am still pretty slow on. Thank you, Helen

Question: When describing Bell's Inequality, Professor Adams talked about an electron in two known states. (ie hardness and color).

Greate lecture. Thanks a lot! I have a question on Bell's inequality. Could someone please explain to me how could anyone get the number of electrons which are hard and black (as shown during 1:17:28 ) or the number of electrons which are hard and not black, etc? In the first lecture, it was shown that there is no such thing as an electron which is hard and black simultaneously. How was this experiment done to calculate the N(H,~B), N(B,~W), and N(H,~W)?

@peersvensson9253

2 жыл бұрын

He was playing a bit fast and loose at the end. The inequality actually is a statement about two electrons, so N(H,~B) should be interpreted as one electron is hard and the other one is not black. There is another subtlety though, which is that hardness, color and whimsyness would not actually lead to a violation of the inequality (which is why he started writing angles at the end). You have to be a bit more clever in how you pick which properties of the electron you want to work with.
