isn't the x-axis = space and y-axis = time ? Thanks a lot, Mitch sir I have mock tommorow

Hey Mitch, great stuff you teach man. Just wanted to point out a typo of your (mine) fav Physicist's name...Thanks

Thanks for the video but isn't this the spelling for "Feynman"?

@nicumaroro638 2 года назад

Hi, I was told the dotted line represents the a W or Z Boson and not wavy, wavy is a photon. Does this matter a lot or is it not a big deal then?

@OSC1990 2 года назад

For IB Physics, it's not the biggest deal. Don't worry too much about that. Instead, make sure you know how to determine an unknown particle in a Feynman diagram (use the charge to figure it out)

@michakozicki8923 3 года назад

Hey, if you look at the past paper N17/4/PHYSI/SP2/ENG/TZ0/XX in 2 a) , the arrow connected to the electron neutrino goes forwards not backwards. Why is that?

@OSC1990 3 года назад

I just took a look at that one, and it's because it's not anti-matter. It's 'regular' matter so it goes forward in time. Had it been and ANTI-electron neutrino, it should then have gone backwards. This question was strange though, because if you check for charge carefully in the middle of the interaction, it should have been a W+ and not a W- boson. But the answer for that one was indeed that it's an electron neutrino. You knew that because it can't have any charge.

@nicolaspereira5705 3 года назад

@@OSC1990 Isn't it because the time axis of that question is actually vertical?

@sarangkulkarni1489 3 месяца назад

I'm a bit confused, at around 10:42, you say that "to see the 2/3e become the -1/3e" but isn't the conversion from a neutron to a proton? So wouldn't it be a -1/3e become a 2/3e hence leading to not the W- but the W+ boson being released?

im wondering the same, did you find out yet

@nasserbensaid3223 4 месяца назад

Teaching this to IB students is truly a complete waste of time. Feynman is just another over rated joker in the world of science. I taught Quantum physics for last 20 years and never mentioned such a nonsense. If you need to read a truly science book then read "What is Life" by Erwin Schrodinger, the father of quantum physics instead of these cowboys trying to glorify themselves!. You will soon realize why Schrodinger gave up Physics and criticized his own work. Teaching this to secondary students is similar to teaching the Shakespeare "garbage" to English students. Many countries are done with it long time ago.

@OSC1990 3 месяца назад

This is subject matter that is prescribed by the International Baccalaureate's Diploma Programme, so arguing whether or not Feynman diagrams should be taught as a comment on my video is counterproductive. In the new syllabus for IB Diploma Physics, particle physics (including Feynman diagrams) have just been removed.
