a gluon can "glu" on my face anyday while we're having a strong interaction if you know what i mean🤤

mass and speed of light

For an average adult weighing 70-72 kg, 21% of their mass comes from electrons as they move across the Higgs field- Higgs field is basically what stops every object with a mass to travel at the speed of light ie- 299,792,486 ms^-1. what about the rest of the mass well it comes from your nucleons namely protons and neutrons which doesn't make any sense because unless a particle is moving at some speed or velocity it tends to interact with the Higgs field because then and only then it can stop it from reaching the speed of light; So, this resistance is what makes up the mass and a stationary object does not have any velocity.

nucleons are not fundamental particles ie they are made up of smaller particles- elementary particles named quarks. The study of Quarks and their interaction with gluons is known as quantum chromo-dynamics, Chromo is the greek for colors so we can infer that your weight has something to do with colors other than Higgs interactions meaning elementary particles have something called color charge, No way they are actually colored their wavelength is really small to be measured but it is a really good analogy for understanding especially for rookies like me. setting the integral rule for the existence of 'color-charge' the net result should be a white light for example a green a blue and a red quark would sum up to give white light and hence it can exist as a particle similarly a color with some other color which adds up and totally nullifies its effect, to sum up to a white light these so basically a quark with an antiquark this pair (of a quark and an antiquark) is known as a meson. quarks exist in gluon fields and their existence brings about flux tubes which is the only possible 'true void' in the universe. A proton usually composes of 2 up and a down quark; but, sometimes quarks might pop into existence out of nowhere and exist naturally inside the proton so there could be any odd number of quarks inside a nucleon.

so your mass is coming from these vacuum chambers in portions and neutrons? Of course no it is coming from the energy fluctuation on gluon fields in which these elementary particles exist meaning your mass is basically coming from energy. inferring from e=mc^2 this energy is huge.

In the beginning, said that the Higgs field stop particles from moving at the speed of light hence giving them mass, so if some particle approaches the spread of light its mass increases exponentially this is exactly the reason photons are identified to be massless objects and the massless objects tend to move at the speed of light.

Ask Ethan: Where Does A Proton's Mass Come From?

“What’s happening inside protons? Why does [its] mass so greatly exceed the combined masses of its constituent quarks and gluons?”

The whole is equal to the sum of its parts. That’s one of the first rules you learn, and it’s true about almost everything in the Universe. If you were to break a human being down into our constituent components, the cells in our body would add up to our entire selves. Same for the molecules in our cells and the atoms in our molecules.

But when you get down to atomic nuclei, something funny happens: the individual protons and neutrons are about 1% heavier than the atoms as a whole. That’s a clue as to what’s happening, but it cannot prepare us for the most mind-boggling fact: the quarks that make up the proton are only 0.2% of the proton’s actual mass!

Why is this? And, if it’s not from the quarks that make it up, where does the proton’s mass come from? We know, both theoretically and experimentally, and now you can know, too!

Two dimensional flavor space? What kind of lame ice cream shop is quantum chromodynamics setting up here?

Me confused as fuck about spontaneous chiral symmetry breaking and the goldstone theorem

[isomorphismes]

Equation (1) of www.math.ucla.edu/~wdduke/preprints/mocktheta.pdf reads ∏ 1 ÷ (1−qⁿ). I started expanding the denominator (in crayon) and found the pattern of + − + + − +’s easier to understand in colour.

Here is a sketch of the "combinatorial tetris" that results. I think the colours make the sources of the terms easier to track, and therefore to get a better intuitive feel for the algebra. (Anyone want to make a javascript app of this process?

Doodling with binomial expansion coefficients helped me understand the central limit theorem, Black-Scholes, and the Jones polynomial.

Ed Witten 1, Sir Michael Atiyah 1 2 3, Lou Kauffman 1 2 and Joan S Birman on how knots relate to physics. Briefly, when evaluating Feynman integrals, you consider all possible paths a particle could take. Some of these paths double over on each other, or loop around in strange ways. Witten’s idea (correct me if I’m wrong here) was to split these paths up into good=well-organised groups that are easier to sum-up. I think this somehow relates to gauge and Chern class.
