The Strong Nuclear Force
Ғылым және технология
Scientists are aware of four fundamental forces- gravity, electromagnetism, and the strong and weak nuclear forces. Most people have at least some familiarity with gravity and electromagnetism, but not the other two. How is it that scientists are so certain that two additional forces exist? In this video, Fermilab’s Dr. Don Lincoln explains why scientists are so certain that the strong force exists.

I was actually dozing off.when you said that 2 atomic particles can - by themselves- emit a macroscopic size force of 20 POUNDS(!), it actually woke me up! Lol. That's the most surprising science fact I've heard in a while.

How exactly do they figure that out they put two weights on two electrons until they can't push each other away I wish they describe that

@@donjr5400 Probably they used an electric field and then they measured the power needed to push protons together. You can then calculate how much that power in Watt equates to a mechanical force. It doesn't matter what the force is because you can translate all forces into each other (because it's all energy per time per area). An electric field with X Watt equals then a mechanical force with Y Newton. So, they used an electric field equal of 20 pounds mechanical force.

isn't that dangerous for a human being shot by repelled proton even though it's microscopic size? :/
Don, you badass. 4:42 Awesome video. Thanks.
Just found this channel. Looks like i discovered another gem of KZread.
This actually my favorite video so far. It explains the starting point as where to compare the forces and to get numbers on them for comparison. Great stuff Mr Lincoln.

Thank you Dr. Lincoln- great video explaining this in terms that almost anyone can understand.
Dr. Lincoln, you should know those gamma ray experiments never end well! Haven't you read the comic books?!
Your explanations are simply brilliant. Happy I found your channel.
One of the best videos out there, explaining it so clear! Thank you
I didn’t know fermilab had its own KZread channel, that’s so cool! For as bad as the fed gov usually is at educating the public, some of the admins like DOE and NASA have been doing a surprisingly great job recently. Glad I found a new channel to binge
Wonderful presentation, thank you. Speaking for my self, I would be interested in seeing the math too, maybe not long derivations, but at least the equations, who figured it out, and some intuitions about it. I think you do this in other videos. Thanks again for your body of work. You have really advanced the state of the art when it comes to physics education for non physicists.
This chemistry teacher thanks you for this simple explanation. I’m definitely going to add this to my nuclear chem discussion in IB Chemistry Option C.
I love your videos fermilab! Keep em coming!
Please!! make these videos longer!!, they are super interesting :)
I love these videos. You get a bite-sized explanation of something that's bothered you for years.
Dude, you're amazing. Thank you so much for these videos!
My eyes are closing...must go to sleep, but first I am appreciative of the eight hours spent listening to your Commentaries, Sir. Good Night Dr. Don. Ana M. Abreu.

It is known that the majority of the science community use SI units, including those in the USA. Additionally imperial/US measures are worked out from the SI standard, conversations are used to arrive at the correct number. This said, huge swathes of people easily understand imperial measurements.

Thank you so much for this wonderful video!
Great explanation even a humanities major can understand. Thank you.
Another great video! Keep it up!
LOVE your videos Dr. Don. Regarding strong force and binding energy, I'm wondering if these three statements are correct: 1) It is the strong force within the nucleons that provides the strong force of the atom's nucleus. Q: Do we know from where in the nucleus the strong force eminates, from WITHIN or from BETWEEN the nucleons? 2) When fusion releases binding energy, the amount of energy released has a correspondence with excess strong force. 3) The fusion that creates a nucleus releases binding energy when the full amount of the combined strong force of each of the individual nucleons is no longer needed 1) to hold each individual nucleon together, and 2) to stabilize the nucleus up to some level. This release of energy occurs because the strong force from within each nucleon is now overlapping to both 1) partially hold together its neighboring nucleons, and 2) hold together the nucleus, to some level of stability. So some portion of the energy of the nucleon strong force that is no longer needed (because some of its "territory" is being covered by the strong force of one or more other nucleons), is released (as heat energy).

Are you referring to the nuclear fission of breaking the binding energy (strong interaction) between nucleons? You used the word fusion a lot. If so than those statements, from my understanding and education, are fairly accurate. For a general understanding at least. Strong force or Color force is the binding energy between quarks and it bleeds out into nearby nucleons and other quarks creating the nuclear force. This strong binding energy in between nucleons is what gives protons and neutrons most of their mass believe it or not. The other little bit comes from the Higgs field. When that bond is severed (fission), like you said, the overlap is released into energy as a gamma ray and neutrino if I remember correctly. Some of their mass is lost in the release but if you get several kilograms of nucleons doing this in Uranium you can get a bomb if uncontrolled and a nuclear power plant if controlled with graphite rods and water.
I love this channel, please keep the videos coming,,,
Excellent video. Thank you for explaining it so very clearly. I feel smarter already.
That was so well explained. Thank you sir!

No matter how many times I watch this video, I love the ending!
Great intro vid,first time in 35 years that I have heard the nuclear forces quantified. While I have known qualitatively that the strong force is the strongest and of short range and EM is long range, I had no idea the EM force in a nucleus is in the order of 20-70 pounds or that the strong is about 100 times stronger. Also the length of strong force being less than the diameter of a large nucleus.

The first time I heard of that the weight of a large car is needed to rip a tiny sub microscopic nucleus apart. At first I thought you could probably pull thousands or millions apart at once with just your fingers if you could get a grip on them, though obviously they would still be strong for their size.
NOW I get it! Thanks!

Man your videos is goddamn great! Thanks a lot, finaly I understand many different things that I always ask to my self.
The strong force is my favorite force, because when subatomic particles are tried to be pulled apart, it is getting even stronger, and even harder to pull the particles apart....and so on
Particles are also waves, so explain a nucleus with the following Proton waves, neutron waves, quark waves, gluon waves. We have not a particle zoo, but a wave zoo. Does that change anything? Do we now have multiple shells of waves in the nucleus?
Nice video
What this video is actually talking about is the RESIDUAL Strong Force. The Strong Force is what keeps quarks together to form protons and neutrons. There's enough left over to then bind protons inside a nucleus.
Link to the particle physics strong force video?

Does the strong nuclear force (SNF) obey an inverse square law? If not, what analogous-to-Coulomb's-Law/Equation does the SNF obey between nucleons? For that matter (pun), what are the equations that relate forces & distances between ANY pair of particles: electrons, protons, gluons, pi mesons, neutrons, etc?
Thanku sir
How does strong force explain nuclear stability?
There are super heavy elements where the strong force is stable, using isotopes located around the island of stability of element 115 where the strong force actually extends past the perimeter of the atom and be isolated accessed and amplified. Also by bombarding element 115 into a anti matter reaction fuel.
The *Core Explanation* of video *Still Remains* ... What is *Mathematical Equation* for strong forces????? Kindly make a video on this...
I was expecting him at the end to say love is the strongest force
Best exclamation ever
What if i made a ray gun that undid or seriously reduce the strong nuclear force in whatever target I zap? Would they just explode or what?
That ending!! xD
If the strong interaction is between quarks which keeps a nucleon(either a proton or neutron)together,how does the strong force binds the nucleus.Well to bind the nucleus should the quarks in one nucleon attract the other nucleon to hold the nucleus?
