4 Subatomic Stories: The amazing neutrino

Of all of the inhabitants of the subatomic realm, it is said that neutrinos have surprised researchers more than the rest. In episode 4 of Subatomic Stories, Fermilab’s Dr. Don Lincoln both introduces you to these perplexing fundamental particles, and answers some fascinating viewers’ questions.

Over the years I find more and more quality youtube channels like this. Finally a positive side of the internet. Sitting at home in another continent, drinking my tea and I get lessons from a physicist from Fermilab.
What a time to be alive.

Thank you, Doctor, for all that science explained, and also for the joy you bring to us

Hi SIR! With my sincere appreciation for your effort and willingness to share such valuable knowledge, I'd like to ask a question:
I have a problem with these little guys here: (charm, top, bottom, strange, muon, tau). I can not fully understand what do they do in the universe? We know for example Up and Down are building blocks of protons and neutrons, Higs bosons are responsible for mass and so on... but how about these particles? What do they build? Or what do they do? And most importantly would universe still exist without them ? Do we need them ?

[NicleT]

As always, ultra interesting. Thank you Dr. Lincoln.

1)Why the Pauli exclusion principle applies to fermions only?
2)How can there be charged waves?
3)does the neutrinos pass through our bodies via quantum tunneling?
4) how many types of particles are there in universe?
(Spoiler: hundreds )
Thanks for recieving my questions.

Love these video's. No background music, very clearly. thanks.

[charulatapanigrahi]

But how are electron, muon and tau related to their respective neutrinos?
How do we know that which one is whose?

[Ambienfinity]

Love Don's enthusiasm, and love for his subject.

I think we have much to learn about this fascinating tiny particle, and I am glad that the scientists at Fermilab are hard at work on the ‘matter’.

[Annimu]

The subject matter of the video is very scantly described but the Q&A segment answered many of my own queries. So yeah this was satisfying.

[Pintuuuxo]

Humor is a fundamental particle in Physics. Thank you Dr. Don

[WhatAreDrums]

I'm enjoying how much of these videos you dedicate to question response. Thanks for being so engaged!

Question: you mention that neutrinos only interact via the weak force. But since they have mass, they must also interact gravitationally. Did you phrase it this way because there is no way to model gravity with QM?

[ankeunruh]

I do remember the news about the start of Kamioka Nucleon Decay Experiment. It brought the curiosity back to my mind, and it took me 20 years to understand, due to the new ways of asking questions...

[Revoluus]

Phenomenal. I'm a chemist and mostly look at electronic interactions, but this discussion about quarks, bosons, and neutrinos has peaked my interest. I might have to study some more physics!

[realdarthplagueis]

Thank you for your amazing videos Dr. Lincoln! And thanks to Fermilab for their amazing work!

[matyasgembala]

That was awesome. The Q&A section is a great addition that brings your videos to an even higher level. Please do keep on! :)

1:04 project poltergeist. That sounds badass af

[nHans]

Whoa, so the W bosons can change particles’ identity? That's huge—it raises all kinds of metaphysical questions!
As a computer programmer, it brought back nightmares of my early C/C++ programming years. Variables and objects were just bytes in memory. They had no inherent identity of their own. Any code that accessed those memory locations could assume their identity to be whatever it wanted. ‘Clever’ coders back then did unnatural things with unions and the omnipotent typecasting operator. I still have terror attacks when I recall debugging those monstrous hairballs.
Subsequent languages like Java and Python assigned a permanent and immutable identity to every variable and object created, banned identity changes, and reduced the power of the typecasting operator to a mere shadow of its earlier self. I was happy; I believed that was the balanced and harmonious order of nature.
And today I learn that the identity of the very fundamental particles of nature can be changed? Noooo...say it ain’t so, please...!

Thanks Dr Lincoln, for making neutrinos more or less understandable to a simple novelist/cabinetmaker.

Fun fact about neutrinos: the first detection of neutrinos was awarded a Nobel prize 7 years AFTER the Nobel prize was awarded to the discoverers of the second type of neutrino.
