How Small Is It - 05 - The Higgs Boson (4K)

Wiki page

In this segment, we cover the Higgs Boson starting with force fields and their particles.

First, we cover Quantum Electrodynamics - QED. We note that a disturbance in the electric field can create a particle – the photon. We show how the virtual photon mediates the electromagnetic force with virtual photons that are actually not particles. We also introduce coupling constants and Feynman Diagrams. We then extend this ‘force particle from a force field’ concept to include a matter particle from a matter field. In electromagnetic quantum field theory, this is the electron.

Next, we cover Quantum Chromo Dynamics – QCD. We show how the electromagnetic force is used as the model for the strong nuclear force that holds quarks together in protons and neutrons and holds protons and neutrons together in the atomic nucleus. We introduce color charge, gluons, virtual gluons, quark containment, and pion exchange between nucleons (the residual strong force). We also highlight the origin of mass for the proton. We then fill out the Standard Model of particle physics with the weak nuclear force and its force particles - the W and Z bosons. Using Beta Decay, we show how this force can change the actual particle in an interaction, not just accelerate it.

Next, we discuss spin oscillation as the origin of mass for elementary particles that lead to the Higgs Field and the Higgs Mechanism, and, as with all other fields, a disturbance in the Higgs Filed should create a particle – the Higgs boson. We show how the Large Hadron Collider (LHC) at CERN works and how the Higgs particle was discovered.

We’ll conclude with a brief look at what the standard model doesn’t cover (like gravity) and some of the theories in development that may very well take physics to the next level (like Super Symmetry). We end with a description of Planck’s Length (the shortest distance that can exist) and its implications for the next generation of physicists

These videos are a masterpiece and deserve an award.

[SC-jhqp]

This was incredible. Such clarity and depth. I'm just sad that I know I will forget most of it.

[JasonMelanconEsq]

The absolute best explanation of particle physics I’ve seen to date! Thank you for taking the time to make this video and to share your excellent narration and knowledge. We are all more intelligent because of your gift of knowledge.

[DJBethettefficial]

I've never seen particle physics explained so simply and elegantly. Great video!

[TerminusAvid]

This is by far the most interesting and exciting channel when it comes to astronomy and particle physics. David's pacing and voice is superb, thank you for sharing your education and experience with us!

[vegassims]

Dr. Butler is awesome. I have learned so much from watching his videos over the years.

[hschnisa]

I am fascinated by people who have the ability to explain complicated topics in a simple way. Those kind are very rare and you are one of them.

[Dr.CandanEsin]

Clear as crystal. The most definitive explanation I have met in YouTube. If one loses attention for five seconds misses loads of useful information. Cordially thank you for your efforts for sharing. Kind regards.

[blairribeca]

On YouTube one can find many misleading explanations for the Higgs Boson, even by celebrated names in scientific journalism. David Butler offers us, the under-educated, a clear description of the Higgs and its function. Thank you, David Butler.

[mauricecanham]

What a great service for science this channel is. Thank you David.

[Ninjahat]

You're still the best, David. Thank you 🙏🏻

[eliotsalandybrown]

How generous of you to teach us so much in this beautiful way. Thank you.

[Murtaskegg]

I just want to reiterate how valuable this channel is. Namely priceless. Thank you, Mr. Butler.

[tcpipme]

You are such an inspiration, a role model. Thank you so much

[hfakos]

I think his pace and tone are perfect for these educational videos. I could listen to his voice all day long. The graphics and scientific summaries are nice too. Kudos to David.

[julians]

I just do not think they start discussing this early enough in school. I didn't hear about these, in an educational setting, until AP Physics in High School, and even that was not this comprehensive. I think this should be introduced as soon as students begin learning chemistry.

[SeanScorpion]

Thank you sir. This is the most thorough explanation of the Higgs boson that I've yet seen. This is the first of your videos I've see yet I've already subscribed.

[mountainhobo]

After a long stressful day, this is what I needed to unwind.

[JoeBlowUK]

I'm just half a Planck length from understanding all of this.

[SirHefferlot]

cant believe vids like this are just 1 click away and for free. what a great time to be alive!
thank you mister butler
