Came for the (g-2)m video, stayed for the Solar Neutrino problem! Your videos are awesome - consistently the clearest and best described takes on particle physics. You deserve to be be WAY more watched! 😄
Hey - maybe you can do a video on why there are only eight gluon types instead of the nine you'd expect (or at least I would expect). I know it has to do with SU(3) but every description i've ever seen made my head hurt.
Hi! The answer is alive, but not finished. As for whether or not neutrino mass is the cause of the solar neutrino problem, that is now fairly clear. But, that merely was the first indication that neutrinos had mass. In the time since, there has been much effort put into trying to figure out what those masses are, and to find the values of other parameters that control how different flavors of neutrinos can change into each other. So, there are also results from atmospheric neutrino experiments, reactor experiments, etc. In order to figure out the whole picture, we need to take information from a lot of different results and put them together. A lot of progress has been made, but there is still more to do. For example, most neutrino experiments measure not the masses themselves, but the _difference_ between masses. So, we still don't know the overall scale of the neutrino masses to the level that we'd like. And sometimes a confusing result does pop up indicating maybe we need, say, a sterile neutrino, but there's nothing definitive along those lines yet. I hope that helps!
Hi! Questions?

Much appreciated! And thanks for the video suggestion!
These videos are very precious to me. Thank you!
Much appreciated! Thank you!
Thanks for uploading it it helps in my semester exams for neutrino physics paper. 🙏🙏🙏🙏

I shall return with questions, in a week when I've had time to digest it thank you
No problem! Thanks!
Could you please explain about the missing of berrylium problem?
I would like to hear more about this theory and if it is still alive or has been laid to rest?
ups, sterile neutrinos! I would like to hear more about this theory and if it is still alive or has been laid to rest?
