100% recommend talking to yourself while watching these videos if you know what he's on about. For example, before he subdivided hadrons into baryons and mesons, say it out loud that that's what he's about to do. It'll help you commit to memory and if you get it wrong, play the video and you'll be able to correct yourself.

Heads up at 29:35 mistake was made, interaction is through the weak not strong. strangeness is only conserved in the strong interaction. The reaction you described consisted of kaons decaying into particles that do not have any strange in them (pions have d anti up u anti down etc ). therefore it must be weak as there was no conservation.
Thanks, good teachers are worth their weight in gold.

Teacher should show a video like this for every lesson starting a topic. You are then revising as going through the actual lessons and if you have to do work near the start you won't be limited by knowledge gained many lessons later
I haven’t even gotten my GCSE results yet but I’m definitely taking physics as an A level. 7 weeks into the A level we’re visiting CERN. My teachers exact words to me today were “learn particle physics” so here I am.

Thanks a lot!! Your videos are very helpful for pre-uni revision. Since I come from outside the UK these lessons are perfect for covering the topics we don't study in my country!
Thanks so much your explanations are great to understand 👍
I couldn't fully understand the difference between a pion and kaon before so for anyone like me, pions have an overall strangeness of 0 while kaons have a overall strangeness of +1 or -1 in other words always have a single strange or anti-strange quark. Pions can have a pair of a strange and an anti-strange quark but their strangeness cancels to zero still keeping their overall strangeness at 0. Also thought I should mention that strange and anti-strange quarks can have a strangeness of +1 or -1 if that wasn't already clear
Thank you so much for this. I’ve been struggling to understand particles for the longest times. I’m so glad I clicked on your video. THANKS AGAIN!!!

True. However AQA only used the former in Feynman diagrams, which is why I omitted the others here. Seeing as though they've removed Feynman diagrams from the spec, I might fix this at some point.

A particle that is not made up of any other sub particles. For example an electron is not made up of anything else therefore it is a lepton. However a proton is made up of quarks so it is a hadron rather than a lepton

Thank you for that brief and detailed explanation on particle physics. I have a question tho. Isn't the charge of electron negative 1.6x10^-19 ? Because you didn't take the negative sign into consideration when you were calculating the specific charge.

So basically, as Issac Newton implied, planes can only fly north on a Tuesday. With that in mind, the gravity on wind resistance on Tuesday's will therefore create an imbalance of the earth's internal energy, simultaneously causing the earth to spin faster north compared to weekends. The strangeness implied will therefore interfere with the radioactive gamma displaced by Chernobyl, effectively rendering all aspects of the apple landing on Rutherford's head useless. We then therefore can conclude that earth's gravity is directly proportional to the electronic voltage within a parallel circuit Hope that helps!
