Quantum Chromodynamics (QCD)

Electromagnetic force down, three more forces to go! Which one is next? Why it's the strong nuclear force, famous for keeping atomic nuclei together. What kind of particles will be involved in this quantum field theory, which is called quantum chromodynamics? Let's find out.

Check out "Is This Wi-Fi Organic?", my book on disarming pseudoscience!

Oh, great, so now we have two periodic tables. That's nice.

I never learned before that for the strong nuclear force to exert force on/between quarks, a total of eight(!) gluons is required. Thank you professor Dave!

Great ! I'm Korean and so impressed that I would like to introduce and share this link with my community members for Physics.

Been looking for a good description of this for like, a week, and this is the first time I've gotten it. Thanks for being so concise, I appreciate it!!

[chancelorhardy]

It's so good to hear a vocal explanation of this. Keep doing what you do Dave!

[elnuraliyev]

Mr Dave, you are going more and more sophisticated! Lovely!

[engineeringconcepts]

Wonderful presentation. Super concise and definitely worth the small amount of time.

After up and down quark. Everything went over my head (bouncer) Well greeat explaintion.. Its just my brain that didnt compete with what you were saying... Thank you professor... I wanted to learn quarks and got an Idea of it..

I always picture red green and blue color charges as three 2D vectors at 120 degree angles to each other with a length of one. Negative charges just point in the opposite directions. With that, it makes sense that r + g + b = 0, r = - g - b, etc. Gluons (eg r - b) are vectors of length sqrt 2. It all just works out.

wait, so the smallest particles are not atoms, but quarks?

[ProfessorWaltherKotz]

This guy will have explained everything in about 2, 14 years from now

[leyharsiplayz]

Who else is here after watching young sheldon

[sustainableslate]

The fact this made sense when I'm in my first semester of physics is great

[loicvalenti]

can't wait for the next one !! need to know

[bot]

I really love your videos professor Dave 💜

[connorism]

Another very handy explanation. Will make sure to donate to your Patreon today.

Thanks Dave, Hopefully Cern won't form a black hole, love startrek original. Story - Orange mist in Bermuda as my ship passed, the 3 layers of pillow clouds, pillow space pillow, couldn't do the math
Not Fractals, maby sub Log e

[jacquin]

AND literary references... I'm in awe.

I think it should be:
u c t
d s b
with the mass increasing as you go right and the columns being particles that pair up nicely due to the weak force.

How does a Right Handed Top Quark decay? Weak Force only affects Left Handed Top's
