- In this video, Fermilab's Dr. Don Lincoln describes the principle of supersymmetry in an easy-to-understand way. A theory is supersymmetric if it treats forces and matter on an equal footing. While supersymmetry is an unproven idea, it is popular with particle physics researchers as a possible next step in particle physics.

I was pretty excited to see an actual equation on youtube at 3:05 and I was really looking forward to an explanation. Oh well.
yeah, a real equation illustrates the concept better than colored rubbish.
There are plenty of channels, or more specifically video courses, that will go into a depth you desire... but to expect it from a layman's video is silly and makes it sound like you just wanted to boast. :X
I THOUGHT I WAS THE ONLY ONE OMG.
I WAS EXCITED TOO.
Like you would understand it if he tried to explain.
Good sir, you remind me the teacher I always imagined and never had. Keep up the good work!
I wonder if he'd adopt us like Daddy Warbucks, only he'd be Daddy Deuterium.
My man!
Anyone else notice the equation for bosons is the one on his shirt?
Yes I did
I also noticed and came in the comments to see if anyone else noticed too
I want that shirt
I ordered one, but it said: Bozo
it's alright to sure us more maths and explain it. we won't be angry we promise.
osemudiame123 yeah, sometimes using abstract references is not exact enough . Throw in a real example.
Force=matter
but we must minimize runtime of the brain!
i guess Im kind of randomly asking but do anybody know a good site to watch new movies online ?
@Alfredo Westley thank you, signed up and it seems to work :) Appreciate it !!
I know Dr. Don is often praised for his presentation skills, but can we take a moment to appreciate his writing chops? Those examples and metaphors are excellent and everything is laid out in a logical, easy to understand manner. Fantastic!
Thank you Dr. Lincoln! I always thought supersymmetry was a diagnosis of Terminal OCD.
lmfaooooooo that was good
Ha. That’s funny.
if a school or a university had teachers or professors that were all like this guy that university would graduate Einstein in every year , im almost familiar with all of the topics that this channel talked about , even though i study architecture being knowledgeable with physics and science in general is addiction to me , however i have never ever seen a channel that explains things like this guy does , his method of simplifying big things for my little mind got me hooked and i cannot get enough of physics mysteries .
i honestly wish i had a teacher like him growing up and i hope this channel grows and more people subscribe to him
+hisham borgol This channel isn't really just aimed at him, I personally believe that it was created to spread knowledge of physics and Dr. Lincoln is one of the tools they use.
*****
thanks for the recommendation , i will check it out but i doubt any other channel can make me understand particle physics the way this channel does
3:05 Goddamit, that was the bit I was really interested in..
+Evan Bell I agree.
Why saying that it is too difficult? With a good explanation everything can become clear. The laziness here lies with the teacher, not the student.
God Jam It
can't you forgive someone who wants to remain civilian friendly
+Evan Bell www.redbubble.com/shop/cern+t-shirts
Scroll down...you can wear it too without going to CERN at least. Also, if you read it backwards its the new recipe for Pepsi w/o aspartame.
+John Toobad To understand these equations would require years of study of "a good explanation" which is why it's too complicated for a 10 minute video.
xtelevisionset Agreed
Thank you, you absolute legends, for enabling me to answer a final exam question I was not even supposed to be able to answer.
That was a great explanation because he said we don't know yet. Thank you Dr. Don Lincoln.
If you tied this poor fellow's hands to his side, he would no longer be able to speak.
Watch "Mitchell and Webb wavy arms". Basically a summary of this video.
Don R. Mueller, Ph.D. Science has actually proven that the movement of our hands while speaking is one of the brain's methods of retrieving memory more effectively.

What
@@laurelharris8519 That's why I masturbate, but it's a private conversation. Yes, folks call me the George Carlin of physics.
Even if you want to 10 lectures on the topic, this is a great overview and a great place to start.
I thought Charity meant Charge and Parity symmetry at the same time
Good one
Overthinking XD
Dr Don makes sure to put physics in the centre of his videos instead of himself, unlike some other (also very interesting) youtube channels. They should learn from him. Thanks Dr Don for the amazing stuff you are teaching us in an amazing fashion.
a bit more detail would have been nice
analogies are always... mehh.
that equation was a joke too
I believe there exists great difficulties when trying to explain highly complexity equations in a video, the best place to seek explanation is in books :)
the medium of video posses the same resources and more as a book just sayin
there is a psb spacetime, a more technical channel
CZcams troggs shoot above their station so much. This material is difficult. It's unapproachable for the average joe except through analogies.
I really enjoy watching Dr. Lincoln's videos; they are extremely well made and easy to follow (funny too!). Thank You :)
Awesome … I can relate to BOTH "Super" & "Symmetry" … they're well integrated into my daily life … and the concept of "SuperSymmetry just blows my mind … good presentation … thank you … !
Real nice videos which provide one a deep insight on the subject
..
Really appreciate the initiative on the part of fermilab because it helps students like me a lot...
Can't thank you enough
As a first year undergrad in physics with at least a few lecturers working on SUSY experiments it's nice to have someone explain it. As most people who on SUSY seem to talk about it without explanation.
Excellent explanation. Thanks Dr Don.
it's 9:25 am, haven't slept yet and now i'm here watching this because of a meme i didn't understand
i don't need sleep, i need answers
Science never sleeps
@Zapper Zapped Dang dude I’m only in 8th grade and I’m already thankful.
Well you probably don’t need to worry about it because if super symmetry were real, we would have found super symmetrical particles at the LHC. We haven’t so it seems increasingly to be a dead end. And with it, particle physics in a trebling crisis.
What privilege to have lunch with such outstanding person...
This. VIDEO was what got me back to pop science when i watched it 6 years ago
Thank You Dr. Lincoln
PeSla here... you look very good in this video and is as helpful as your book on the LHC for the state of research. I think there is a lot to be discovered there that can be done without having to share financing possible with larger projects. Thanks for you cautions and expertise as a dose of reality in your help the science and philosophy chat forums as the drama unfolds as we look into the speculative world at the foundations between facts or principles- as for now what we see of Higgs.
"The next couple of years will be very exciting" :(
Wow, you are the best, great explanations
THANK YOU PROFESSOR LINCOLN...!!!
How.... did he explain it so well, the analogy with the adition was spot on.
hit like if sheldon brought you here!!
Yes yes yessss🤣😁.
Particularly season 10 where he was trying to solve equations of super symmetry and other quantum theories but then all got depressed because no one found anything for years.
@@shaily191 season 11
Particularly 11*02 and bcoz of Leonard
I was searching for this commemt , yes sheldon brought me here , becoz of him i am more interested in becoming a phsycist!!
Thank you, sir! I am no science brain, but still I fould your flow logical and it held my interest to the end. I await your lecture on how supersymmetry explains higg's boson, dark matter ...
Awesome channel!
Thank you, Dr. Lincoln. That was charming, humorous, and clear. I came here looking for an answer to a question. It seems like years ago I read something about either symmetry or supersymmetry that proposed that sub-atomic particles were all actually one one particle that just appeared different depending on what energy it had. Is this indeed a characteristic to some degree of supersymmetry?
As you can tell, I'm a complete layman in this area of study. I find it fascinating, and yet very hard for me to grasp. If you happen to find this message, please if you can point me in the right direction good sir. Thanks!
I'm actually here because of Sheldon Cooper. Been rewatching TBBT but this is the first time I am ACTUALLY curious what supersymmetry is.
Me too!! LoL! 😆😆
Same lmao
what a nice video...and such a great host :)
2:41 damn i had 9
awesome video, continue like this!
Yes. Force carrying particles can interact with each other. For example, one of the particles that mediates the weak force is the W+ boson. Because the W+ boson has a charge of +1, it is affected by the electromagnetic force (the photon), even though it is a force particle itself. There are also many more examples like this.
I wish I had understood this before, thanks .
Mass does not play by normal mathematical rules. We might use 2*2=4, but Mass has the ability to double in effect when multiplied . 2*2=8.A chain reaction seen by a run away gravitational well. But by symmetric rule, is weakened when divided. 8/2=2. Because of this, the amount of energy needed to satisfy the effect of mass is gigantic in nature.
Or in this case squared. E=MC^2
Very nice explanation of "supersymmetry" and it ruled out leftovers of stereotypes
Wow. So incredible
Wow......makes you think and wonder.
Do we necesarily need the existence of the super simmetric particles? Is it possible that they are the same particles that behaves different under different conditions? i.e. I am thinking on electron pairs behaving as bosons in superconducting materials. Or may be they somehow convert into its suppersimetric particle. And may be that is the reason why they don't appear in accelerator collisions. That may not be the right condition for them to appear. High energy itself may be the condition that breaks the simmetry.
awesome! it's funny and knowledgeable! thanks!
loved this!
Thank you for this video; I Love your explanations. BTW, I would like somebody to explain me what an supersymmetric sphaleron is.
Thank you!
Could the graviton have a super symmetric particle? Assuming it exists, should it be more massive than the graviton? Would gravitonino be a "mass" particle? Is there a chance to the detect the gravitonino being heavier and then have some certainty super symmetric particles may exist? Can an estimated mass of the gravitonino be calculated? Could this hypothetical particle gravitonino be responsible for the additional gravitational field that keeps the matter in a galaxy from running away by centrifugal force?
Our buddy Eddie always ahead of his time.
Dear Dr. Lincoln: Great videos. Suggestion for future videos: GAUGE SYMMETRY. I've tried to understand it but failed.
Combine supersemitry with fractals And your ahead of the game!! Just an FYI..
Would the Higgs Boson be symmetrical to quarks? I heard that the newly discovered Higgs has spin like how quarks have spin.
If this is possible, then are the other Bosons symmetric to lepton particles? If so, then does that mean there are another 3 boson particles which have a connection with the W, Z and photon the same way nutrinos come from decayed leptons?
So just swap the colors and.... Nope don't get it.
I think He's just saying it doesn't work now like a formula mathematically but you can make if you add in new hypothetical forms of matter and energy
Justin Reinhart thanks for being upfront lol.... I’m lost too
two equations @3:35 then one equation @4:00 now its symmetrical
Get it now. I actually knew that already. But I was confused thinking why 2 equations in the first place .
Take one equation.
Swap two things.
If it accomplishes the same math then it’s symmetric.
Would love to hear you comment on the supposed 'error correcting codes' found in some supersymmetry math.
Wonderful
Well described. I still wonder why superpartner particles are considered to be heavier than standard particles?!
Another motivation for studying supersymmetry is that scientists cannot make any headway or progress with the more complicated versions of physics. They resort to simpler versions (such as maximal SUSY) in hopes that something will turn up that might apply to the real world.
I need help making equations. I found E useing Fibonacci sequance and sphere packing in higher dimensions. The Aether that everyone say doesn't exist.
I really wish this channel went deeper. Like more math, fewer oversimplified analogies.
You should check out PBS Space Time.
if you look at the history of science..it takes a loooong time to understand stuff..
i like this vid ...only one i have seen so far that says the calculations may not be correct
Thanks I'm still 14 and most physics videos i watch explain in much more detail and complexity but this video i could understand. Thanks. Also building on the cousin particles, if a standard particle changes does the cousin particle change to? If i am not mistaken this is one of the principles of Quantum Physics.
i an 14 right now and I want that answer
I think you should know by now considering you have had a good 7 years to find the answer
Einstein is the gratest scientist but my question for you is about the warmhole and the which could only gets into the warmhole and has -ve pressure i also loved your teaching s way
Really most excellent video, thank you!
That equation is also on your shirt. Interesting.
*Whoohooo! Batavia! Represent! What up B-Town!*
'Okay I was only kiddng is actually too complicated'. Legit slick nerd humor that's actually funny
Where can I purchase the same t-shirt
They are the best equation available for now to understand reality and getting a standard model including string theory.
isn't positron the antiparticle of electron?... so if we accelerate positron to the same energy as a muon would we not get anti-muon? or further accelerate it and get anti-tauon?
please make a video of how supersymmetry can be related to string theory
Thanks, well explained
what is the best darius build against ad comp ?
It has been more than a couple of years. Is it still very exciting?
With the results coming out of CERN, it's starting to look more and more like supersymmetry is wrong. I'm curious if there are any other good theories to explain those phenomena you mentioned (e.g. dark matter) that don't involve supersymmetry?
At 3:15 when he was like "okay and heres the fermion equation...nvm lol"
I was LIKE BITCHHH NOOOO
THAT EQUATION LOOKED INTERESTING. Y U DO DIS TO ME.honestly i love learning the complex shit.
Just realized there are 20 other comments like this...o
You might want to pull this video, because Dr. Sheldon Cooper won a Nobel Prize for his work an Super Asymmetry.
very clearly explained ^^
Do they have a Newsletter?
I REALLY wish the scientific community would either come up with a new word to use when a theory has been tested and retested and finally reaches the point of acception (IE: Theory of Evolution, Germ Theory, etc) OR that they would STOP calling a hypothesis a theory. It creates so much confusion for the scientifically illiterate/uninformed (not an insult, just an observation/my opinion).
Anyway, I just had to vent that. I appreciate the videos y'all make and the education they help me attain/round off.
Perhaps early in the universe during inflation the broken symmetry DID produce a positron, but it when through a phase transition and converted back into an energy field INSIDE of spacetime causing what we call dark matter. Like Hawking Radiation once energy converted to electrons and positrons the matched pairs instead of inhalating, the positron somehow was transferred into spacetime causing it to hit its elasticity yield point. So the electrons went on to make matter and the positrons went on to make potential energy in the form of an "empty" gravitation field-dark matter...
are you assuming the gravitational force has a DC offset? :P
What qualities do they have that differs from standard particles?
In particular, a supersymmetric partner of a fermion is a boson, and vice versa.
I immediately pressed like button when sir took the equation off and he was kidding.
Thanks to this video, I just discovered three of many cousin particles last month.
Was this presentation pre-vetted by Dr Sheldon Cooper before being posted?
can you have force without matter?
Antimater is something different. The way antimatter interacts with matter dictates more the behavior of subatomic particles rather than gravitational force. Antimatter is easily destroyed by matter and creates more matter, plus energy. Tha supercolliders essentially smash atomic/subatomic particles together at a high speed (thinking in terms of energy and mass, more energy will generate a different/larger mass) to create different matter (antimatter). They try to hold it in an electromagnetic field then discharge it, measuring what subatomic particles/charges are generated.
Please explain sometime what is all on the black board ......Please make a video on ....
so you got a symmetric equation, but where is the 'super-' part ?
Aren't the positrons emitted during gamma radiation examples of at least one "cousin particle"?
Nice 😍
Interesting.
The ancient Greeks were familiar with this theory, as were Kabbalists, hence; In Plato's cosmology he declares three simple components, Same, Different and Existence. In Kabbalah, the Tree of Life declares the Cosmos to be composed of Form, equilibrium and Force. In other words Matter, equilibrium, Energy, which is super symmetry. Now - how did they come up with this so far in our history??
Equilibrium is the 'Operator' and Force and form are the 'Products'; the only two possible states of matter and energy which are always in relative equilibrium; whether in the state of nucleosynthesis or Decay (Fusion or Fission). My mathematical terminology may not be quite correct but the theorem is.
So were the next couple of years exciting? Asking cause I don't know (not snark).
I have a question...which I had a thought....but i must do this in a series of questions to come to the right conclusion ...1st question:...does sound have a focal point
Sound is not a lens so therefore it doesn't.
7 years passed. Any improvement on this?
I heard a physicists saying he found "computer code" in supersymmetric equations. What does that really mean and what are the implications for us?
+flying frenchman Cool off take a col shower
He works at MIT you should go visit his office
Is the equation on his shirt the same one he was going to look at on the board but threw out because it was too complicated?
This guy is a total legend. Super comfortable, I’m sure he’s a great teacher
