The Weak Nuclear Force: Through the looking glass

Of all of the known subatomic forces, the weak force is in many ways unique. One particularly interesting facet is that the force differentiates between a particle that is rotating clockwise and counterclockwise. In this video, Fermilab’s Dr. Don Lincoln describes this unusual property and introduces some of the historical figures who played a role in working it all out.

Thank you so much for recognizing Wu Chien Shiung's relevance... as a young grad student I constantly feel insecure and afraid if someday I'll be overlook in science just for being a girl... what you said made me feel so happy and proud and also recharged me to continue on studying hard so that one day it can be me making a huge breakthrough in the STEM field!

I really look up to you, Dr Don... Thank you for all the things you've taught me and for being an amazing person.

Mrs Wu definitely deserve a Nobel Prize.
We should keep raising our voices for this issue so much that a separate award is created to honour all those who deserved but were left by humanity in the past 😋

She also skipped a long-planned vacation to run the experiment herself. My hero!

[ghanshyam]

Really sad to learn that she was overlooked, her experimental design is brilliant!

To be clear, he also isn't on the Nobel prize committee now either. Had me going for a minute there.

At 2:35, what I think what you really meant to say was that if we measure the spin in the direction of motion, then it will be parallel or anti-parallel. It will be another matter if we, for example, instead measure the spin in a direction perpendicular to the direction of motion.

"Now, neither of these guys knew how to test this because they were *_cough_* theoretical physicists"

It's not hard to imagine how the Nobel cmt is blind and corrupted by ignoring such a landmark contribution of Mr. Wu. The discovery is historical also beautiful by iteself: the weak force only likes left handed particles, which may imply huge potential for future discoveries.

I've been wondering about the nature of the weak force for years, because it seems noone is covering this topic in depth.
Finally a first step! *However, the video still hasn't taught me much about the weak force yet. Only about its preference for a certain spin.* I hope more is coming :-)

"Theoretical Physicist" -cit.

I laughed. I laughed a lot

I am so glad I follow this channel. Thank you, Dr. Lincoln!

[alexjaybrady]

Her experiment showed something stranger than pretty much anything else ive heard in any of these great videos, and theyre all often mindblowing.

[richthenative]

Did not now of these three physicists, thanks for the annotation pertaining to spin. Special thanks for the important history lesson. Reminds me of Watson-Crick and Franklin, whom was essentially passed by. Good to make things right to help keep us on track to do the correct thing...always. Great series of educational pieces from Fermi.

[williamfrederick]

You explain everything perfectly I'm beyond awe-inspired by the content of this channel

[anthonywilbanks]

I really enjoy all of these Don Lincoln videos. thanks for making them

[agarwalamit]

I finally subscribed to your videos. It really brought back the motivation to learn more of Physics and revise my maths. You have kept the videos simple (not necessarily easy to grasp everything though) but included bare minimum information to get an insight into the topic.

[pronounjow]

After watching this video (a couple of times so far), this is the first time I have any understanding of the weak force at all. I'm looking forward to more videos on this and related topics!

[slalibert]

Great video on a mysterious and fascinating subject. More please!

[bruinflight]

Every time I see a new upload on this channel it's like a stadium of avid football fans cheering a touchdown in my mind :-)
Thanks Dr. D!!! Keep 'em coming!

I'm so glad I came upon this channel.
