Thanks to all the great minds studying nature, and helping Engineers build a better future so our human civilization can advance as a whole for the best.

For anyone looking to do reading on the subject but in layman's terms that won't overwhelm you, I highly recommend Quantum Physics What Everyone Needs to Know by Michael G. Raymer. Everything she has discussed in this video is explained in the first chapter of the book, so after reading that chapter and then coming to watch this video, I feel like I understand and can keep up with what she is talking about. Also, I highly recommend you take notes as you read. This will help the information stick in your head as you read, and you won't feel as lost because when you don't understand something fully, you will know as you are trying to take notes on it. This sort of comprehension check is crucial to those of you serious about understanding these topics!

I like how you point out that light behaves like a wave. People often claim quantum mechanics is not intuitive. Actually, it is rather surprising we found a tool, namely math, to describe the world outside our commonly observable length, time and energy scale. Let us acknowledge that having intuition of the later might as well be an illusion. It took us a long time to understand Newton's laws.

Quantum mechanics is the bane of regular physicists. Its rules and theories are so against the normal thinking about physics that it blows most people's minds, confuses others, and even fascinates some to the point of obsession. To think that we, as humanity, can know what happens at such a small scale is incredible. We cannot even see atoms, and yet we know not only of their existence, but also of their properties and how they will behave. We know about photons simply because they displace electrons, as shown in the video. We know so much about something that seems impossible to even measure, and I think that is simply incredible.

I feel every single physics course should start with the fact that many fields encompass the entire universe, and particles are just epiphenomena of said fields. An excitation of higher energy in comparison to the vacuum state, if you will. And time is the rate of permeation of said excitations. I could never understand physics until I understand this simple fact. I feel that people need to understand how things truly work at the most basic of levels to ever hope to grasp reality. If you don't explain this, you are explaining it wrong. All analogies give you a misconstrued viewpoint of reality that is hard to overcome. Example: the double slit experiment is solved if you realize that the photon IS the field, not the particle. So when the excitation of the field travels through the slit (which, in of itself, is composed of excitations), a piece of the field itself is traveling through both slits, as the field is everywhere. The only thing separating space is the rate of permeation. Particles are higher energy in said field, and this energy is NOT constant. It is spread out through all the universe, but focused into a 'point' that is not purely localized. This is why we think of particles in probabilities. It all makes sense. Perfect sense. But you have to change how you think about physics. I am myself a laymen, but starting with the classic explanation instead of going straight to the quantum field explanation only confuses things for everyone. Not only that, but it feeds into anti-intellectual pseudoscience about quantum woo woo. All because of the misunderstanding of what quantum mechanics actually is.

You were a bit all over the place there in the third paragraph, but I got the gist of it. Anyway, I agree with you on this, man. At least when it comes to understanding how reality actually functions. This stuff is just old. I overwhelming support the more modern ideas of Quantum Field theory for understanding the universe. Though as I said, "at least". The older ways of looking at the universe still have practical applications.

idk if this helps but my chem teacher told us this: 1. Unless light of sufficient frequency is used, then no electrons are ejected. That is there is a threshold below which no matter how intense the light source is, no electrons leave the metal. 2. If you are using light of a sufficient frequency, then as the light source is increased in intensity (brightness), the number of electrons ejected increases. 3. As the frequency is increased above the threshold, the velocity of the ejected electrons increases. 4. From this we can conclude that energy is proportional to frequency, and that the proportionality constant is Planck's constant, h.

At what level, and what in particular are you interested in learning? Physics is a very broad subject, with textbooks covering a huge spectrum of content and mathematical rigor. If you're looking to learn more about quantum mechanics, I would suggest David Griffith's text; it's a good first foray into quantum mechanics, typically used for mid/upper level undergraduates. You'll want a solid understanding of elementary calculus and linear algebra though; you won't get very far into QM without it. If you haven't had any formal physics instruction, you should probably take the typical route, starting with classical Newtonian mechanics and working your way up to the good stuff.

Samy Hacker In fact it's not the case... the only wavy thing in quantum mechanics is the behavior of the probability of observing a particle at a certain location. The ONLY wavy thing is the "mathematical tool" you use to describe this probability of being somewhere or somewhere else. Particle dont move together to form a wave (unlike water molecules). Be careful when you hear words like "particle is a wave" or "behaves like a wave", its a misuse of language (due to historical reasons... the guys at the beginning of 20th century had some difficulties to find appropriate words to tell quantum effects, so they used pictures from classical physics... and these words stayed in spite of the new perspective gained the last 50 years). So what is important to understand is that a physical theory only gives us a way to view a specific part of the world (quantum mechanics cares about small things isolated from the rest of the world and observed with a big apparatus). The main lesson of quantum mechanics is that IT DOESN'T MEAN ANYTHING to say things like "photon are like this or like that" and to imagine these particle as small balls that behave weirdly sometimes. The quantum way to see the world is only about the INFORMATION you can acquire about the world, given the tools you're going to use to look at it. If you use a certain tool in a certain way (light or electrical current or a magnet etc...) then you will only be able to acquire a certain type of information about the particle you're "looking at" with these objects. This vision may seem disappointing or too restrictive to give a good description of the world... and in fact not at all ! It gives the most precise description of the world we've ever had and more than that, it's the only way to understand the microscopic world ! Are you giddy ? I hope so because I am 😉

But surely it would not be the same photon leaving the electron as entering. The characteristic of what makes one photon that photon would surely have to do with it maintaining identical characteristics to when it first was emitted by a particle and not interacting with any particles for it to be the same photon. Else you might as well say everything is everything aside from potentially dark matter and energy which could exist simultaneously to pre-existing laws but independent from them. This seems less like a physics question and more like a philosophical one.

I do feel that the connect provided here can be simplified. It obviously already is but it feels like she keeps talking about the same concept (light is both a wave and particle) for a good chunk. However, I like the summary provided in the end. It is a great way for students to recap what was said in the video. :)

A black hole should be an almost but not quite perfect black body. I've seen several different deviations from the ideal in the theory of black holes. The most obvious one is Hawking radiation, an ideal black body only emits radiation based on its temperature, black holes however, are predicted to emit a certain amount of radiation based on their mass in addition to their temperature. Another source of non-idealness is rotation, while a non-rotating black hole without Hawking radiation should be an ideal black body, in reality it's very unlikely for a black hole to form without at least some rotation, the rotational effects of a black hole would interact with the radiation it absorbed and emits in such a way as to not quite match up with the way an ideal black body emit radiation. Finally, and this is one I'm the least confident in, I've seen at least one theory that predicts that for a low mass, and thus low radius black hole some extremely long wavelength radiation might be able to 'miss' the black hole as it passes the region of space it occupies. This is because the region of space the black hole occupies may be too small to actually absorb the entirety of the energy spread out through the wave.

Better off reading it slowly on a book than hear her. Good for a audio refresher, but she goes too fast. Even though I know this stuff, it's hard to keep up with what she is saying. SLOW DOWN LADY. You got a sexy voice, but you are talking about things that needs to be broken down for many people out there who are new to it (isn't this why it's a "CRASH COURSE PHYSICS"?). Then again, I must suggest, for those who are new to it but interested: OPEN A BOOK. NO alternative to learning from a book. Books will teach you in sec what these videos do in minutes. The way book "talks" to you is nothing like a video that "speaks" to you.
