Fermilab physicists really care about the mass of the W boson. They spent nearly a decade recording collisions in the Tevatron collider and another decade analysing the data. This culminated in the April 7 announcement that this obscure particle’s mass seems to be heavier than expected. So why do we care? Because understanding why this particle even has mass was one of the most important breakthroughs in our understanding of the subatomic world. And because measuring its precise mass either doubles down on our current understanding or reveals a path to an even deeper knowledge. The FermiLab discrepancy is a tantalizing hint of the latter.

If you really want to know about the W boson mass measurement at FermiLab, your favorite W-boson-mass-hunter, Don Lincoln, has you covered. https://youtu.be/wRhAZ9M-lI8
-
I feel like this channel started out late high-school level and has slowly pushed us into late college level stuff. As some one who’s been here from the start its great and I feel like I have received a valuable education minus the deep math
-
That’s one of the most challenging recent videos. Wish I could say I learnt something, but it doesn’t click yet. Some learning and re-watching to do first! Don’t dumb it down, it’s entertaining to be pushed to learn.
-
This show is one of the best things I’ve ever come across. Thank you PBS, Matt, Editors, Effects, Audio, and all the nameless folks who bring this freely to us all. What a time to be alive.
-
This was excellent. The 3-D mapping of the "Mexican Hat" really helped me understand how a symmetrical field can still have random elements. That "ahh, now I get it!" moment.
-
I love being talked through the hieroglyphics.
-
Matt: Don't worry. It's not on the test. Some physics teacher somewhere: Oh, but it is!
-
This was such a great explanation beyond the classic "the particles bump into the higgs field slowing them down" explanation.
-
I normally understand your episodes, but most of this one went over my head. I'm sure that just reflects what a complex topic it is. Thanks as always for putting out amazing content! Even though I didn't understand a lot of it, I'm glad to know that these exciting developments are happening!
-
I can usually follow along and understand each episode, but this one went way over my head. Guess I need to refresh my memory with a few more episodes... Of SpaceTime.
-
This is probably one of your more difficult episodes to grasp for non-physics majors, yet also one of your most fascinating, it will be exciting to see whether the Fermilab result holds up to scrutiny!
-
I'm not supposed to be in this class...
-
I’m studying these at university right now and I gotta say you did a great job summarizing the most important concepts. Explaining symmetries is quite challenging, and those animations really help to better grasp the ideas involved.
-
Finally an explanation of the higgs mechanism that answers a lot of my "ok, but where did it come from?" questions! I love this episode.
-
It's episodes like this that make me wanna go rewatch the 10 or so episodes before. I find it's like a new layer of understanding being revealed every rewatch. Goes to show how info dense these things really are!
-
As someone who is just about to graduate with a BS in Physics, I'm glad that I'm now at least able to follow along with 90% of what's going on in this video. To be fair, I am not a particle physicist and am focused more on astrophysics, but I can still at least figure out what's going on.
-
I completed the survey before this episode came out... and this episode was almost exactly what I asked for in my survey responses. I loved the deeper mathematics here... and I'm going to have to watch the episode at least once more to completely absorb the equations. Thank you!
-
I come here for the heavy puns. So far i'm massively impressed.
-
As as non-physics major, I really like seeing these episodes which explain the formula and then show how it gets converted to some kind of real world representation. It's a gap I often have a hard time bridging in my head.
-
I responded to the episode idea survey about a week ago and requested that the higgs mechanism explained episode be revisited and here it is! Thank you PBS Space Time! Thoroughly enjoyed it! :D
