This video was inspired by my Veritasium video - your mass is NOT from the Higgs Boson: • Your Mass is NOT From ...
The point in that video is that the Higgs mechanism provides mass to fundamental particles but that mass is much less than the mass of the conglomerate particles they make up. This video was an effort to disentangle the different aspects and types of mass. Thanks to Sean Carroll for taking the time to discuss this with me. Check out his page: preposterousuniverse.com/
kilograms, but sometimes it's quoted in terms of energy/(speed of light squared)
yo
When someone knows what he is saying, it is pretty easy to be convinced and change your mind. Sean Carroll must be an awesome teacher.
He communicates really well - loads of concepts introduced but plain English used and every new concept introduced and explained one at a time. I understood the entire thing, thanks!
Agreed, awesome teacher.
Wow does he ever! Refreshing after watching some nonsense "experts" talk about time.
2Vertasium needs to do a vid on time!
Justin nitsuj not 2Veritasium but may be helpful: th-cam.com/video/FVINOl0Ctfk/w-d-xo.html
Yes, he does communicate very well, because some concepts are simplified to the point of complete BS.
In fact, Newton's equation F=ma does not hold at relativistic speed.
The force required to obtain a certain acceleration parallel to the direction of travel is different than the force required to obtain the same acceleration, but perpendicular to the direction of travel, resulting in the strange concepts of longitudinal and transverse mass, which are different at relativistic velocity.
en.wikipedia.org/wiki/Relativistic_mechanics#Force
So if you don't care about the rigor of science, by all means listen to him, but if you do, don't.
@@hereiam2005 He was just simplifying things. I think you're taking it too far.
Thank you! I've got lots of good stuff coming up soon - stay tuned!
Sean Carroll is truly an amazing physicist
Personally I like the idea of him having the conversation, and asking the right questions to lead use through the explanation. Its a nice way to integrate the person who runs the channel in with all the amazing people he meets
Anybody else here from Andrew Dotson?
Haha, me, came here for the nostalgia
Dr Carroll is so good at explaining difficult concepts, without coming off as condescending at all. Thanks!
man this guy knows his shit
Like what?
Guy this man knows his shit
Of all the videos I've seen that purport to explain anything about the Higgs boson, this has been the most informative, and I didn't even expect it to be mentioned.
I never comment but keep these types of videos going. The quantum computing and this video where we are getting a condensed version of a boring lecture are great!! I can't get enough. Keep em coming!!
Sean Carroll is awesome. I'm so glad you got him to collaborate with your channel.
more episodes like this please! it made a lot of things click in to place in my mind which I hadn't thought about enough before to do so myself
When I've heard Sean speak before, I never really felt that engaged in what he was saying but in this instance, I really understood what he was getting at! I will make an effort to watch you more in the future Sean! xD
Great video Veritasium, thanks a lot!
Demystifying is a strong word to use.
What this video did really well was to show me that I don't know jack shit about what mass is. I may however after watching this be confused at a slightly higher level, though I'm not sure about that at all.
So thank you for a great video - I think.
itsjustameme All he really did was rationalize the mathematics by putting words to them. He didn't seem to be concerned with forging an epistemological connection between empirical observation/experience of mass, massless light, etc. and the physics concepts that explain them.
Any critically thinking person should question the assumption that mass is a form of energy and want to know more than just the fact that "Einstein's philosophy said so" and "the equations work."
Haha. The more you learn, the more you realize how much more there is to know!
discountconsulting I am speechless. And thank god I am speechless in this instance, because if I said anything at all, infinity people from all over the net would argue over what any of the terms I was using actually meant! lol.
The Lappin I stopped learning, as soon as I witnessed my University maths professor lose all of his money, and his superannuation too (you could in those days) at the races - where I made enough to start a computer manufacturing business... I know no better today.
you stole that quote from Fermi.
Some how that made sense! I wish this had been around when I was in high school or college. Kudos to Sean Carrol for making something that was previously rather mystifying pretty clear to me.
Yay!
Fantastic Derek! Another superb video to add to your canon that I shall come back to from time to time, as it is conceptually dense in a delightful way, and I know I shall learn more as other little nuggets click, on re-watching. Thank you for your passion for physics, science, outreach teaching through your film making that we all benefit from. You are a shining example of what makes the internet a great force for good and touching lives at its best.
I didn't understand all of this. but it did clear up a lot of questions and misconceptions I had! Very good, keep them coming!
Not only does Sean explain ideas/theories that are difficult to conceptualise very well, he also inspires his audience.
Sean is great.
Always love his explanations.
This is just great. Smart , inspiring and entertaining. Keep up the good work . We all need pleople like you
Sean Carroll is one of my favorite academia/mainstream physacists !..........He's always verbally clear & concise no matter how difficult/abstract the subject matter........almost like a Feynman in that sense.
I had thumbed up this video at some point in the past. But I don't even recall seeing it, let alone the brilliant information shared in it. This makes depressed!
I remember seeing now, and the information shared, third time is the charm!
There is so much knowledge crammed into this video.
Great and simple explanation of what the higgs mechanism explains.
Thumbs up for explaining measuring mass in terms of energy! I've never heard that before!
Excellent job with this video, complex theories were explained very well.
I love these interview kind of videos. I would love to see more! :)
Agreed. Outside of watching hours of free lectures online, it's sometimes hard to find technical information and I feel most documentaries anymore don't really have much to offer me as they're aimed at people with little to no understanding of the subject and spend a great deal of time on elementary analogies.
Absolutely fantastic video! Love Sean Carroll.
I've learnt more, or I should say I've understood more, about basic physics from Sean Carroll than just about anyone else. He reminds me of Richard Feynman's paraphrased quote, "If you can't explain something in simple terms, you don't understand it".
This video is fantastic. I have a degree and PhD and have read lots of explanations of energy, gravity and relativity. Sean's way of explaining it is direct and very visual. If you didn't understand it watch through a couple of more times as he does whip through it very fast :-)
Need more of that Sean Carroll
Yes! Loved this video! Thank you.
Thank you very much for these videos
THANK YOU... DR. SEAN CARROLL...!!!
"someone moving fast with respect to me is moving slowly with respect to someone else but the way it is warping spacetime can't possibly change." "right"
I had to pause the video there and let it sink in. wow. What a strange and wonderful universe we live in.
Thanks Derek, I always enjoy your videos and I Always learn something amazing.
Awesome video! After doing relativistic energy and momentum (using four vectors/invariants), etc, hearing what Carroll said about relativistic vs. rest mass would have saved me a lot of confusion. My old text book really belabored the idea of relativistic mass more than it had to.
I certainly will. Keep up the good work! It's very much appreciated.
@Veritasium This one reminds me a lot of the way @BradyHaran shoots his videos. I love it!
Thanks Derek, this is awesome!
That just blew my mind!!! thats amazing
Huge carroll fan ... lectures and books alike... thanks for this!
great video. i think i have to watch that a few more times..
This man is an amazing teacher!!!
Always looking forward to new videos from your second channel :-)
need more sean carrol!
A little bit abstract for a young french student like me (i'm 17) but your videos are still my favourites with numberphiles' one, it's great work and I hope wou'll keep doing such great videos :D
awesome content ....cleared some of my ideas .....science bless you
I'll admit that I'm doing a PhD in HEP and his explanation of why the Higgs is necessary (chirality in the weak interaction) is the first one I properly understood!
I agree, this video clicked very well with me too. Some sudden revelations about some stuff I already knew a bunch about.
The very end was like a "Woah" moment that really cemented it all together. More mass = More energy = A larger gravitational field. The spinning barbell worked so well for me.
Fantastic thanks for the knowledge
Great video, I had to watch some parts twice :D
However I did not get what the higgs field changes. When the higgs field slows down a particle, than you still have the problem that faster particles will see moving in the other direction or not?
too cool . . . would like to see more like this !
Excellent explanation.
I think I am starting to honestly grasp why space-time-gravity has to be so interconnected.
Great explanation!
Damn. I just learned A LOT. Ty Prof. Carrol.
Absolutely brilliant episode... MOAR!! Feeeeed me knowledge!!! ;)
great job dr carroll
Love this channel
Excellent!
I like this guy. More of him, please (not just talking about Mr. Carroll either).
I UNDERSTOOD THIS!!!
HOORAHH!!!!!!
Hey. is that Richard Feynman's desk?
And yes he is very good. I have a couple of his Great Courses that I listen to in my car. The one on the higgs is especially good.
Thanks Sean.
I would like to see more content like this. More advanced and in depth :)
I said at the equator. Look at my subsequent comment. I explained that to find the velocity at a particular latitude, you multiply by the cosine of that latitude. Cheers.
Love dis guy's voice
Thank you and GOD BLESS
FINALLY
This helped clarify fictitious forces for me, especially the Coriolis effect. Rotational motion viewed from an accelerating reference frame is inescapable. The Earth is spinning and revolving around the sun, which is orbiting the center of the galaxy.
That 30-sec explanation of the reason behind the Higgs Field was extremely enlightening. Every other explanation is very vague, usually boiling down to "We predicted it exists". Thank you so much for the 30sec "We need electrons to spin one way, because spin determines whether electrons interact with the weak force. But, relativity says spin depends on the PoV - unless it's massless. The Higgs Field gives mass to otherwise massless particles".
Of course, one can dig deeper into the rabbit hole. Why does Higgs fix the PoV issue? It seems like mass is mass.
(A couple times you mentioned Higgs Boson gives mass, as opposed to the Higgs Field. You appear to know a lot about physics so I'll just take that as misspoken)
Sean Carrol DESTROYED william lane craig. it was so sad, and oh so entertaining.
Amazing debate. Sean is an excellent communicator and gave theism a beat down, and all Craig could bitch about was Boltzmann brains. William Lane Craig should retire. When you start responding to criticism from Physicists with "oh, that's just your hunch", it's over for you.
I saw it too. Craig didn't have any counterargument to the scientific facts and arguments presented by Sean Carrol, at all. All Craig could do is react in childish ways, undermining his own credibility further. It was almost embarassing his opponents as well.
It was wonderful to behold :) Will Craig ever debate the Dillahunty ? Matt would rinse the poor old boy
WLC destroys himself.
This thread is hilarious!
So Dr Carroll destroyed Craig, huh? Not according to cosmological physicist Dr Aron Wall on his blog Undivided Looking. He gives a comprehensive description of how several of Caroll's rebuttals didn't touch Craig's points and how several more were completely misleading.
As someone with a physics degree and a love for classical philosophy, I kept cringing at how badly Caroll kept misconstruing philosophical arguments. Dr Caroll uses Aristotle's metaphysical motion idea all the time! But since he doesn't actually know what it means he doesn't realize he does it. He also badly fumbles on causes. He obviously doesn't know what he's talking about on these areas outside of his expertise so he doesn't know what he's refuting.
He then commits a perfect example of an argument of authority fallacy by citing Guth, who believes that the universe is eternal, but who admits he has no idea how to get past his own theorem!
Further hilarity ensues from all the people who get butt hurt by the Kalam cosmological argument but who advocate the Multiverse! Positing the Multiverse just is acknowledging the truth of the KCA. It just is a Transcendent cause of our universe that has a beginning. The KCA doesn't actually mention a god at all. But you're all too busy committing the genetic fallacy since if an apologist says it it must be wrong!
But what's most hilarious to me is the fact that you all sound just like William Lane Craig fans. Neither you nor they have any earthly idea what the physicist or the philosopher are talking about but you're both convinced that your team totally destroyed the other!
Oh, and if you want to know the speed at any given latitude, multiply that speed by the cosine of the latitude. e.g., I live in Madrid, Spain which is at 40.4ºN, so multiply 1674km by cos(40.4º)=1674*0.762=1275km/h.
At the north or south pole multiply by cos(90º) which is zero. At the equator, multiply by cos(0º) which is 1, right?
This is the best explanation I have ever seen on mass. Wish I could give it 2^64 Likes.
Hard to find people talking about topics such as mass in a logical way like this.
e=(mc2)2+(pc)2 is the equation for moving items and not just the sitting still of e=mc2 .
Great amount of fundamental information in short amount of time!
It has more weight.
That makes sense, thanks.
7:42 hasn't frame dragging (gravitational field warping due to rotation) already been experimentally observed by Gravity Probe B?
More like this and with Sean Carroll! :)
So the fotons can have spin +1 and -1 if they are going one in opposite directions of the other?
Oh man! I LOVE physics, I LOVE your channel, and YOU sir are awesome for doing this! Have a GREAT halloween!
When something is rotation (say the barbell he was talking about) what it actually means is the center is stationary relative to the rest of the thing that is rotating. So the WHOLE may be considered stationary in relation to you but the parts are moving, in orbits around the things center.
My question therefore becomes, what is the smallest thing that doesn't have any sub-parts that can still be considered to be rotating?
awesome! thank you
Thanks, that's what I needed to know! :)
Makes me happy that one day I may completely understand what he's talking about
I'm not sure I understood all that in one viewing - but man that guy speaks like a boss!
I love this guy.
Damn, so if you spin something really fast you increase it's gravity.......... COOOOOOOOOOOOL!
Lol... I just started spinning things in my room and saying "Ha! I just increased your gravity! take that!"
grah55
Try to spin yourself very fast, maybe you turn into a black hole xD
***** If you try spinning yourself faster and faster, you'll probably explode before you build up enough energy to become a black hole. :P
Jonathan White
'Tis why I said maybe xD
Well he'll never know unless he tries right? :P
q
mass is energy but it also change itself in respect to speed in its elementary particles
If relativistic mass is the mass an object has in the stationary point of reference (M is bigger since we see it move)
and rest mass is the mass in the object's point of reference (M is the same since it doesn't see itself moving)
and photon having its own mass even though it has 0 rest mass,
then does the higgs boson interact differently in different references? And more importantly does it interact with 0 rest mass particles?
Sean Carroll's my hero.
Can one disentagle particles from the Higgs-Boson field temporarily? What would, theoretically speaking, need to be done to achieve such a disentanglement?
Because travelling at the speed of light would be...neat.
Actually the angular velocity is measured in a change of angle over time, usually radians per second. That doesn't change. The OP was giving the equivalent linear velocity at the equator. The linear velocity does change depending on where you are.
7:35 - is Sean talking about the frame dragging effect here?
Hmm. unless I have it wrong, at about 2:50 he says that the mass of electrons, quarks (fundamental particles, in effect) are given mass by the Higgs BOSON. As i understood it it is the Higgs FIELD that supplies the mass and not the boson. The boson is what was discovered at CERN, but was important not in itself, but because the Higgs Boson means that there is a Higgs field, which was what they were looking to confirm.
Does inertial mass increase as you approach the speed of light? Because I didn't know that relativistic mass was any different from any other kind of mass, I had thought that it did.
3:59 I absolutely agree with that sentiment and have railed against the term for many decades. In fact, I never used the term in any of my physics classes so as not to confuse my students.
Question, how can we objectively tell if something is rotation? I can make a whirlpool with water in a bucket by stirring the water in the bucket or by spinning the bucket. So without a reference frame, how can I tell which one is actually spinning?
What is space time and how does (speed or mass) of an object affects space time?? if that make any sense pls answer my question...
I heard about space time getting affected through some parameters of a body..i need to know what and why it is??
Thank you
If I wanted to learn more about increasing gravitational field due to rotation, what topics or keywords could I google/read? I can't seem to get away from links teaching me about classical gravity on a rotating frame. Thanks!
