Professor Dave Explains
Professor Dave ExplainsGet ready for one of the weirdest things in modern physics. Particles that pop into existence from nothing and then go back to nothing again! This phenomenon, called quantum fluctuation, is happening all the time, all around you and even inside of you. It’s the quantum foam, and it elucidates the third law of thermodynamics.

02/14/2025 - 11:20 PMDoes this ever lead to permanent creation of particles? Or does this only pertain to these extremely short lasting virtual particles?

02/14/2025 - 11:20 PMI love this theory, it's closer than big bang.

02/14/2025 - 11:20 PMThere's a very profound issue in applying the uncertainty relation to time and energy. That's because time is not an operator! The particles "popping in and out" of existence is such a misused analogy that it is one of the most common misconceptions in modern physics, and it is a direct result of this misapllication of the uncertainty principle.

02/14/2025 - 11:20 PM3:53 nope this acually gives me a unfathomable amount of hope 😁. If heisenberg uncertain principle was proven wrong how ever then i would probably have a existental crises and mental break down

02/14/2025 - 11:20 PMAre rotation and angular momentum another pair of Heisenberg uncertains?
@Kiwi2703
02/14/2025 - 11:20 PM2:20 Why can't this be explained by gravity or electromagnetic force? You just said that sentence but didn't explain it at all. I thought all objects attract each other with gravity…?
@marcuslombardo8615
02/14/2025 - 11:20 PMHi Professor Dave and anyone reading. Can anyone explain something to me? Why are we sure that the Casimir effect is not due to gravity? Don't the two plates have inherent gravity due to their mass and so attract toward one another?

02/14/2025 - 11:20 PMIm foreign student,and i cant found any vid about this theme on rutube,thank you dave it was informative to me
@Bruhaustindavis
02/14/2025 - 11:20 PMI'm taking quantum mechanics right now, and it's an interesting course, but the concepts aren't emphasized as much as the math. You don't even need to understand what the math means to do fine in the class, because you are simply asked to find this value, derive this equation, etc. Although these are somewhat simplistic videos (they don't really cover much of the math that these principles are derived from), they are so incredibly valuable to me because they take the math I know and really give it meaning. Thank you!

02/14/2025 - 11:20 PMNEVER LIKED THE cOPENHAGEN THEORY. TO MUCH OF A LEAP OF FAITH AND THE CAT ANSWER wHHHHAT NO……
@dgrando202
02/14/2025 - 11:20 PMWhat energy? What kind of energy if an elementary particle which is as far as we understand the rawest form of the energy it could be, is already in that state. What energy does it take? And how does it take the exact ingredients to become the resulting particle particle

@Alysia.rpd3
02/14/2025 - 11:20 PMYou said the more exactly you know the time span of a state the less you know about the amount of energy of that state. But then suddenly you said the shorter the lifetime of a particle the greater is the uncertainty about its energy. Aren't these two things different?
@moscowlostin6159
02/14/2025 - 11:20 PMGood tutorial Professor!!!!!! I've been watching your math, physics, and chemistry playlists these days. I've never felt that science was so intriguing, even as a student studying all those things every day.
But here's something I don't quite follow: Aren't the 2 parameters in Heisenberg Uncertainty Principle representing the possibilities of observation? How come they represent the magnitude of E and t themselves later on? If the possibility that we can observe something is bigger, doesn't mean the thing itself is bigger. Did I mix something up?

02/14/2025 - 11:20 PMI hope you're not trying to disprove God.
@josephshaff5194
02/14/2025 - 11:20 PMEinstein did a paper on Capillarity as well . . . I should enjoy hearing you discuss that some time. Cheers!
@cerwe8861
02/14/2025 - 11:20 PMthe casimir effect can actually be explained without quantum fluctuations and just the van der waals force, but quantum fluctuations can be seen and proven in other phenomena, e.g. the Lamb shift

02/14/2025 - 11:20 PM@DOD-see the vid? You see my stuff? FLOW. 😉👍
What you saw being sabotaged? 😐 prelude to FLOW. Reverse it works to as wolf as in training day wolves.
However, FLOW is real. 😉👍
@crazieeez
02/14/2025 - 11:20 PMI think there is a misunderstanding. The vacuum is something. Virtual particles are something. Virtual particles can exert a force. As for virtual particles coming in and out of existence, is not true either, the net energy is always positive and never zero.
