Physics For Physicists, but made simple :)
I'm a physicist who is improving her physics skills by exploring the ideas and ways we see the world. I rely on Albert Einstein's book "the evolution of ideas in physics" to prepare the videos. After all, I'd rather get information from the best possible scientists.

The Casimir Effect in 2.7 Minutes (Quantum Physics)
The Casimir Effect is a fun finding of Quantum Physics: the vacuum is not empty so two plates placed very closed to each other experience the famous Casimir Effect. What is the Casimir Effect you may ask. Well, it's the finding that there is less quantum fluctuation between the two conductible plates than in the rest of the vacuum: overall the resulting forces applying on the conductible plates press them toward each other.
In 1948, a certain Hendrik Casimir predicted the existence of a curious phenomena in Quantum Physics occuring when two conductible plates are placed very close to each other.

What Do Complex Numbers Mean In Physics?
Просмотров 321Год назад
The meaning of physical concept is more important than the math behind it. Complex Numbers are incredibly useful in physics in order to let us manipulate concepts. In this video I briefly introduce complex numbers and explain why they are so useful. And sometimes we need special numbers to do mathematics operations that are not possible with the other numbers. And this is how we can answer the ...
The Heisenberg Uncertainty Principle in 2.7 Minutes
Просмотров 434Год назад
Quantum Physics is largely based on the Heisenberg Uncertainty Principle, a famous but rarely intuitively explained principle. Werner Heisenberg developed what is now known as the Heisenberg Uncertainty Principle and explained it beautifully with this sentence: "The more precisely you know the position of a particle, the less precisely you can simultaneously know the momentum of that same parti...
Physicist Explains Everything We Know About Time
Просмотров 684Год назад
Physicist Laure explains everything we know about time & answer the question of "does time even exist?", so you can explain "what is time" and build your knowledge base. The idea of setting time aright, or of understanding time is new. Newton told us that time is called "duration" and is the same everywhere. That's what we call relativity. It took Albert Einstein and his thought experiment of r...
Do Vacuum Fluctuations Create Particles?
Просмотров 857Год назад
Quantum Physics claims that space is not empty, and some say that particles and antiparticles are created in the vacuum. The question is: Do Vacuum Fluctuations Create Particles? Modern Quantum Physics suggests that no, particles are not created, but that we are in the presence of fluctuations due to the disturbance produced by our interactions. The creation of particles and of virtual particle...
Why Don't Electrons Crash Into Their Atom?
Просмотров 8 тыс.Год назад
Quantum Physics and the wave nature of electron tells us why don't electrons crash into their atom? Classical Mechanics predicts that electrons should crash into their atoms, and Bohr's explanation of quantized orbits doesn't give a satisfying answer to the problem. Instead we must turn to Quantum Physics and to the wave properties of particles. de Broglie gives us the relation p = h / lambda t...
Are Photons Even Real? (No, but... )
Просмотров 1,3 тыс.Год назад
Quantum Physics quickly introduces the concept of photon to explain how light is both a wave and a particle, but Nobel Prize Winners argue that photons are not real. They represent quantized chunks of energy, but to the question 'are photons even real?', we are better off answering 'it depends' or 'not really'. In science, we have strong experimental evidence that atoms and the electromagnetic ...

The Particles That Do Not Exist (But That We Love) 👻
Просмотров 235Год назад
Quantum Physics is torn over Virtual Particles. Virtual particles help us make sense of quantum interactions and why the vacuum is not empty. But people tend to treat them as real, and it limits their thought. The question is: What Are Virtual Particles? keeps resurfacing in quantum physics. In fact, we talk about The Particles That Do Not Exist (But That We Love)! 👻 In order to understand virt...
Bell's Theorem Proves That Our World is Quantum, it Cannot Be Mechanical
Просмотров 8 тыс.2 года назад
A Great explanation of Bell's theorem and the Bell inequality. Bell's theorem proves that our world is quantum in nature and cannot ever be explained by mechanical physics. John Stuart Bell derived the Bell inequality and provided a fascinating answer to the EPR paradox initially posed by Albert Einstein, Boris Podolsky and Nathan Rosen on the concept of quantum entanglement. Bell posed Bell's ...

Its because of the aether
Your accent is so cute 🥹🫠 Video have passed like it's 2 seconds, reminds me the relativity principle 😁
Very nice explanation
damn, that makes a lot of sense!
As a retired college prof (NOT in physics) I was wildly impressed by your explanation. Way to go!
Life saver, better than chatGPT
Nice
Was attentive to your explanation at my best, Just saying happy subscribed to your channel. 🎉 🧠
If virtual particles aren't real, maye particles in general aren't real. Just a misconception due to the history of the definition of an atom. take for example the double slit experiment. if we measure just one time, the copenhagen interpretation states the particle is in super position until it hits the detector. but if we continue to measure, like 2000 times, the wave nature reveals itself. if we think about particles as excited quantum fields, there's no point like object in space, just as there are no real particles, rather our interpretation of the wave function and it's probality density. also, it is possible to explain the casimir effect without virtual particles in a pilot wave theory framework with it's quantum potential. I can provide the math.
That was helpful, thanks.
Laure where are you?
How does one measure the quantum fluctuations of the electromagnetic field?
I agree with Andrewbordor4891 below, that the zero-point energy (the aether) causes pressure on matter, and probably is the root cause of the expansion of the matter in the universe. But I don't agree that it causes gravity just by itself. Gravity is more likely a separate type of field emanating from matter which pulls on any form of energy (and therefore also the zero-point energy). At a black hole event horizon for example, the velocity of the pulled zero-point energy is the speed of light, therefore light can't leave, it has a relative velocity (relative to zero-point energy) equal to the speed of light at the event horizon. So, imo the modern "aether" has a double nature, it pushes on matter, and also is pulled towards matter by the gravitational fields. Small matter objects follow the movement of the aether, caused by large matter objects. This double nature, causes a balance act which explains much of the behaviour of both the universe as an object, and the objects in it.
Just curious what has brought anyone who reads this comment to this video❓

Off grid lifer. I want to diy this and other sci-fi generators so after I die people can find them and speculate.
Over my head but it sounds really smart. Thank you, definitely not a waste of time.
thank youuuuuuuuuuuuu so muchh
You explain things well. You have a new subscriber 🏆💯🙏🏾🙂
MAYBE IM MISSING THE POINT, but if numerous people measure variable / subjective "stuff" from different perspectives, the results will um er vary, even in a vacuum
You missed it
In relativity, time is the distance along a world-line. It is a local and not relative. The "time" that is relative is unphysical, it is the arbitrary choice of a particular slicing of the gravitational field
Thing is, the Bernoulli principle is why the ships attract. Two submarines would also attract
The Bell inequality simply shows that the particles do not have a definite value before measurement and nothing else. However, everyone is wrong to assume this rules out every class of classical local hidden variables.
I agree with you. The title is misleading. Do you have references to elaborate on that ?
@@W-HealthPianoExercises what is your perspective on entanglement?
@@bustercam199 I did not look technically into the problem. Just as intuitive hunch I am still essentially siding for Einstein and Pauli, but of course not with a set of static "hidden variables", rather with a dynamic "mechanism" which allows after entanglement the spins to permanently remain out of sync (or negatively correlated, at least in a statistical sense, in such way they still match with Bell results and experiments). It would be nice to look into it, but life is too short... 🙂
@@W-HealthPianoExercises Agree. I think Einstein was correct because he understood physics is supposed to describe the dynamic behavior of a system and not just probability amplitudes that (incidentally) give a correct answer to final states--but do not rigorously describe how "particles" actually arrive at a particular quantum state. In its current state, quantum mechanics is incomplete and will never explain entanglement because there is nowhere to put it in the existing framework. But, even more importantly--it does not really exist in any meaningful capacity or in the mystical way imagined by the vast majority of the science community.
@@bustercam199 I agree with you. They got all backward. It's the macro world which is indeed a statistical representation of an underlying more precise behaviour of packets of energy. I imagine it will take a lot of time to get rid of all the BS which has trumpeted and still is. It has become like the financial world. Too much BS going around and being perpetuated without really turning on the cpu 🙂
Bell's Theorem does *not prove that the world is quantum or demonstrate entanglement either.
Nucleus is so small, its just 1/23,000 to 1/145,000 size of atom. So the probability electron hit the nuclues is very rare but not imposible
It isn’t just electron capture. The electron spending some time inside the nucleus is also responsible for the hyperfine splitting (whose transitions give rise to radio astronomy) and for the ability to measure the proton charge radius spectroscopically (due to the small shifts in the hydrogen energy levels for s states when we take into account the finite radius of the nucleus or just proton for hydrogen).
Bell inequality violations are more general than most think. Check out MIT's John Bush explaining Bell violations in HQFT. You can violate Bell inequalities with classical light, Ising models, Brownian motion, chaotic balls and water waves. There is a lot of misinformation about this subject because few understand conditional probability on background fields (non-Kolmogorov probability). HQFT violated Bell in a simple system with water by modifying well geometries. Classical analogs exist for spin-1/2, superposition, entanglement, tunneling, Unruh radiation, Hawking radiation, etc. All of this is a media fabrication. Ask Andrei Khrennikov (arXiv:quant-ph/0003017) about what constitutes "non-Kolmogorov" probability. Quantum mechanics is an outdated theory. The Standard Model is a FIELD theory. QM can't even explain the Pauli exclusion principle. The field commutators vanish! Get it? Quantum states are an abstraction from field ontology. They don't really exist! Fields are trivially nonlocal and measurement is giving readings on a complicated and macro-level measurement device. The states are not really observable. There are no particles but fields. That is the MODERN understanding of physics. CS grads are ignorant. This stuff doesn't even rise to the level of the 30s, where field theory took over. There was only some problems developing the theory of renormalization, accomplished mostly by Ken Wilson by the 70s. These videos are embarrassing.
Photons are a mathematical abstraction. Light is real, photons are not.
Because they are good drivers.
Thank you very much. Great work. it would be very nice if you can make a tutorial on legends and color schemes.
Great video
The simplist answer is they can't be squashed în the nucleus, 'coz of uncertainty principle în regard with their mass. If their mass would be the same as proton's, they certainly smash!
Does wave package is why we call them particules , i mean does particules are wave travelling in packages what simulates a particules?
Not really, light is a wave and it isn't localised at a point so it isn't a particle - but it has discrete energy levels and a single energy level is one "photon" of light. You can't have a light wave that's 1.5 "photons", it needs to be 1 or 2 (or more). This is a particle-like property. Also when light interacts it does so at a specific point rather than across a wider area, which is another property we'd expect to see with particles.
Great explanation! I’m not scientists but I felt like I could grasp the concept after your real work examples 🙏
Wow! you are amazing for sharing these secrets with us <3 thak you so much, it's really the best video for MatLab figures that I found on YouToube. If you can allow me to ask more secrets: how can I specify the "box" property to be "off" only for the figure, but not for the legend? And how can I specify the "font size" for the numbers on the axis to be different? And is it possible to also specify the axis thick marks, like the primary to be outside and the secondary to be inside? Thanks a lot ! Big hugh :)
I have the same question about legend, have you found a solution? :)
Thank you for the thorough explanation 🙏🙂
The ultraviolet catastrophe was logically invalid thinking. They didn't realize atoms have finite size and the field around them is smooth, so as they bump into each other, the interactions are smoothened, low-passed by this gradual field gradient instead of the false assumption of the idealized model. Therefore ultraviolet light is radiated in very diminished amounts, and no ultraviolet catastrophe happens and the concept of quanization is not needed.
I observed shot noise in my wireless optical preamplifier which can be explained by quantization of electricity into electrons, no photons are needed.
This was rather simple
great video! thank you!
A very valuable explanation. Thank you.
How to save each graphic element separately in png?
So, are they buzzing around or oscillating or what? How can they remain stability, when in some cases they are nearer and the other further from the nucleus, thus attracted differently?
Caused by gravity... the press of the dense aether on either side of the plates. Matter and the aether repel each other. The aether does not just disappear but bunches up in the space away from the matter, much like a berm left by a snow plow. This immense mountain of aether is what is pressing on the plates from the sides. It also presses downward, causing what we call gravity.
you mean atmosphere?
No. The aether or quantum space is pressing on the plates inward. There is denser and more aether outside the plates than between the plates. The net effect is a push of the plates together. Conventional thought is that all matter attracts other matter. The Casimir effect is that the root cause of gravity, denser aether or quantum space, pushes the plates together. The plates are NOT attracted together, rather pushed by the same aether that causes gravity.
@@andrewbodor4891Im gonna need amore in depth explanation, youthink that the vaccum generated by the closeness alongside the charge of the plats is not the primary cause but instead an effect of "aether?" What is that exactly?
I agree that the zero-point energy (the aether) causes pressure on matter, and probably is the root cause of the expansion of the matter in the universe. But I don't agree that it causes gravity just by itself. Gravity is more likely a separate type of field emanating from matter which pulls on any form of energy (and therefore also the zero-point energy). At a black hole event horizon for example, the velocity of the pulled zero-point energy is the speed of light, therefore light can't leave, it has a relative velocity (relative to zero-point energy) equal to the speed of light at the event horizon.

Hiya, I've got some questions as I am having issues implementing your code. Taking 1:08 as a screenshot, your code is split into two parts. For the part of the code "Picturewidth..." and below, do I need to copy this after every single figure I create on MATLAB or can I include it at the bottom of my document and be done with it? It would be cool if you could share a document showing the implementation of your code within a MATLAB livescript rather than in isolation (to made it idiot proof haha). Appreciate the work Ciao
Thank you! I'm so tired of hearing people talk about "particles popping in and out of existence" 🙄 So refreshing!
