What a gifted teacher Clear concise and comprehensive Thank you for demystifying and making this physics accessible.

[@user-oy3hp7gv5n]

Hopefully she starts teaching English too cuz... that punctuation though.

[@an9431]

Wow wow wow am very impressed and thanks a lot. Am a retired paediatrician (66) teaching his daughter high physics.

[@rushdanfirdous8606]

Thank you for these amazing videos. Love all the content. Has made my studies really easy. But it would be really helpful if you could also upload or direct me to a video related to particle accelerators and detectors(Edexcel). Thank You!

[@davidr1971]

thanks. very clear description. can i ask someone about 9:04? is the strange-antistrange meson a pion? isnt it a phi meson?

[@raphaelsantos3541]

It's not a phi meson. IT decays much faster than a pion. I got momentarily confused as well

[@jsytac]

Yes, a 'strange : anti strange' meson is a Phi (not a Pi) meson.

[@RahulSingh-ey2uy]

anyways thank you really helped me been struggling with this topic for ages

[@NoOne-yv2ei]

Why would a down quark and an antidown quark become a meson instead of annihilating? Mesons are named to be of a mass in between baryons and leptons, but not all of them are, for example omega-minus

[@shaharyarqureshi6894]

Excellent teacher

[@Msfaizan1986]

Meson is up quark and anti down quark?

[@NoOne-yv2ei]

No it is any quark and any antiquark

[@samirparajuli7433]

but what is the difference between pions and kayons in terms of quark composition

[@cormacbell3124]

Kaons are strange mesons (they have a strange quark). If the meson doesn't have a strange quark, it's a pion.

OMG ! I love all these little guys. In fact, the only thing I have on the door of my fridge is a set of 16 magnetic pieces, each representing a subatomic particle , with a funny little face and the name of the particle underneath . But all this is too much for me. Too many names to keep track of. Obviously this is for people who are quite familiar with the subject. No put down intended. It's just not for us poor fans of the subject who don't have a background in physics .Still fun though . What particle is this ? = ) Ha, ha, ha !

[@drcalvinlin28]

What is the point of study this stuff

[@timwalker4760]

Pions are not strange particles - you shouldn't be stating the neutral pion contains strange and anti strange quarks

[@NoOne-yv2ei]

One strange quark and one antistrange quark works out to strangeness zero (-1+1=0)

[@pedrumsalimi3466]

cheers g

[@agneljoseantony.a3745]

Baryons like protons and neutrons exist in atom. Where did these mesons exists???

[@NoOne-yv2ei]

Uh… particle accelerators? They probably decay really fast
