A little precision at the end to avoid confusion : At 14:19 the symmetry which is referred to is not the color charge symmetry of chromodynamics (which is also based on the number 3), but the flavour symmetry. I've been a bit sloppy in the animation and the colors I've chosen might seem to suggest that this is the color symmetry (even though quarks do indeed respect the color symmetry) Many thanks to my friend Thomas who helped me write this video : www2.physics.ox.ac.uk/contacts/people/harveyt

@@hyperduality2838 Hm.. I won't say you're "wrong" per se, but that's a very sloppy and inconsistent set of uses of the term "dual". A few examples of different uses: - "Syntropy". No idea what that is. A bit of Google gives the only (real) definition as being related to psychology, not physics. Using "dual" to try and tie some (I'm guessing) metaphysical woowoo to real physics. - Gravitation is not "dual" to acceleration. Einstein's equivalence principle states that gravitational mass is equivalent to inertial mass. Both types of mass are related to acceleration in the same way (that's the whole point of the principle). Using "dual" just straight up incorrectly. - Potential energy could be thought of as "dual" to kinetic energy I guess, in the sense that they're typically written as opposite sides of an overall energy equation. Using "dual" in a slightly questionable but not totally incorrect manner. - Positive charge vs negative charge (and N/S magnetic poles and similar). Using "dual" to mean negation. - "Photons or light are dual". They're literally the same thing. Using "dual" in a rather non-sensical manner. - Bosons vs Fermions. This is probably the closest to the common (physics) use of the term "dual" you've got listed, at least if you subscribe to the ideas of supersymmetry. - Except that you claim Bosons are waves and Fermions are particles. Both types of objects are waves _and_ particles. What that means in any sort of intuitive fashion is anyone's guess still (all of those "interpretations" you hear about), but your assertion isn't quite right. What _is_ true is that Bosons have a symmetric wave function while Fermions have an anti-symmetric wave function. We can also state that Bosons are "force carriers" while Fermions are "matter particles", but that's starting to shift the intuition back to your original not-quite-right definition. The type of wave function is the important distinguishing factor. This particular little rant has nothing to do with your use of the term "dual" though. So yeah.. again, you aren't necessarily "wrong". Each use of the term "dual" you applied could be considered valid in their own contexts. The problem is that by listing a whole bunch of different contexts together, you're implicitly asserting that they're all equally meaningful and that simply isn't the case. (Though its a common trope among woowoo artists to try and convince people that their nonsense is relevant without doing the work that would prove otherwise by making implicit contextual associations to real work that has been done by real scientists).

You are explaining stuff much better than most other youtube channels. You don't add any unnecessary or disturbing things to the videos (no stupid jokes, no 5-minute spinning logo etc). You repeat the most important things in a non-disturbing way. Also the narration is great, it's not too fast and you make pauses, that help to better understand what you are talking about.

This is how science communication should be like, as in at the end one should realise that even at the highest level Physics makes perfect sense and it doesn't have to be mind numbingly inaccessible. I once read a quote somewhere, like, if you can't explain something well then you haven't yet understood it well. There's surely a lesson there for pop scientists that for the sake of romanticising science either over exaggerate or use stupid analogies to dumb it down too much. You've found a good balance.
