The mustache wave function collapsed!
ooohnoooooo, it's like Michael @vsauce without a beard
Apparently that cat is not alive. The wave function has collapsed, and the mustache is dead:D
@@juzoli Don's mustache is/was a cat. Confirmed.
Maybe this is Don from a parallel universe. Where instead of being evil, he just has no mustache.
@@MuttFitness He was the evil one all along. And we just got the good Don back.
Does it mean that his evil plan, to build a huge neutrino gun and shoot the Earth with it is cancelled?

Actually the best proof of Tom Selleck’s mustache is its gravitational pull on hot chicks.
Maybe we should invest in a detector to find out? Measure it's waveform and force it through a pair of slits.
Keeping Fermi Lab on the cutting edge of research is a source of pride for local science enthusiasts, thanks!
For science enthusiasts all around the globe!
@@rael_gc ha ha Let's prove it's a globe first before you get too excited
@@johnkean6852 oh dear. Moving on.

Not only local scientists! Canadian scientists too!
Dr Lincoln is back! Good to see you, sir. 👍
Fermilab deserves much more funding and Dr Don deserves a raise. 💕 ☮ 🌎 🌌

Then why is privatesi "wasting" its time watching this?
@@benhall2146 .. To make a good point that you cannot refute because it's blatantly true... How will this knowledge (if actually true) help, practically speaking again? As a down to Earth guy? Who funds it? What choice did they have in the matter?

Congrats to Fermilab on 0.5M+ subscriptions! I've been loving all the lectures and video series on this channel!
For April fool's could you please make a video like this explaining something extremely mundane, like how a door work? Thanks
It would be mundane until he goes off on a tangent explaining how the combined uncertainty of the atoms and their constituent parts mean that the door is open and closed simultaneously. Further extrapolation of which will show how the door is everywhere all the time, including how it becomes a portal to anywhere and anywhen in the multiverse as a result. Someone/something will then knock on the example, free standing door he is using, from the other side, causing him to freeze up, unwilling to answer the phantom knock.
No no, that's top secret. Even American presidents don't know they work!
How about how the s on the end of 'door works' disappeared and all the misinterpretations could change the presentation and any experiments involved. ;-)
It's mundane until you bring statics into the mix.
Yay! Don's back!
I have two comments.
1 - You're the only person I've listened to who had managed to say super-duper whilst actually talking about something serious. A true skill.
2 - What happened to your moustache?
I lied, I have a third comment. Thanks for helping people like me understand what people like you are doing, it's great.
Dr Don is back! It's been soooo long - the notification that there is a new Fermilab video literally made my day. :)
Also, the VFX in this episode are a real step up, the person responsible for the editing did a great job!
Great video Dr. Don! However, I was wondering when you are bringing back "Subatomic Stories"? 🤔🤔👍👍
Every 50-100 years our minds are blown away by new information. I refuse to believe that we grasp '' the bigger picture'' just yet. Great video!
Don, you are one of my favorite channels on CZcams.
Your uncanny ability to explain complex things clearly, your manner of presentation and quirky sense of humor are amazing.
I eagerly await each next episode.
I studied engineering and did 3 years each of math, chemistry and physics although I have been working as a business consultant for the last 25 years..
I did some nuclear physics at college but clearly not enough and oddly it was a chemistry lecturer who mentioned quarks in passing one day 45 years ago.
I clearly remember the day but did not give it much thought again until recently.
After a chance visited to Turkey in 2019 I was amazed at the ancient Roman architecture that is to be found there.
During the COVID break I had time and started to watch more about ancient history, which also led to cosmology and of course sub-atomic particle physics.
Out of curiosity I wanted to know more about "quarks" and quickly discovered a 'new world'
Seeing the standard model for the first time recently made me realize just how much has happened since my college days.
From the very first episode of yours that I saw I subscribed because I immediately recognized that you had something special.
And the similarity between the infinite small and infinitely large are fascinating even if not completely predictable after the fact.
Applying quantum physics to understand biology is also truly a fascinating topic e.g. bird navigation and the consciousness of human minds
So thanks for your effort to help make these topics understandable, compelling and "entertaining".
There once was a lady named Bright,
Whose speed was much faster than light.
She went out one day,
And in a relative way,
She returned the previous night!
"We're not 100% sure that dark matter exists" - thank you for setting the record straight! I've seen so many people accepting dark matter as a fact when we just don't know.
Yes, we should be precise in science and say we are 99.7% sure that dark matter exists. There's always some remote possibility we are wrong.
@@cloudpoint0 Where are you getting that number from? It sounds a bit off.
@@benjystrauss2524 If you ask 1000 scientists if they think dark matter exists, 997 will say it does. But you are probably correct. I may be lowballing a bit.
@@cloudpoint0 What you are thinking of is sigma significance, not what individual scientists think is true, but how confident we can be in the discovery. 99.7% is a very high ball, as it would mean that dark matter has been verified to 3 sigma, which is not the case: this would have been absolutely massive news. Either way though, I really want to see your source.
@@benjystrauss2524
Three represents the few scientific nutcases that think 26.8% of the universe’s energy is not a fact in spite of multiple lines of evidence that can measure and detect it. It doesn’t mean the detail nature of dark matter is known but its group effect and existence is without doubt. This is at least a three sigma conclusion.
I’m sure dark matter made lots of headlines when it was discovered by Fritz Zwicky in 1933. I think Dr. Don is just saying an actual particle has not been found to associate with dark matter. He cares about this because he is a particle guy.
Dark matter could be something other than a particle although there isn’t really another sensible alternative that hasn’t already been ruled out. But we know dark matter of some kind exists. It isn’t remarkable to think that it is a particle somewhat similar to a neutrino, otherwise known as the ghost particle. Or do you doubt that neutrinos exist too since they can only be detected when moving at near light speed? Cold dark matter moves slowly so detection is not possible in this way.
Why are you so opposed to reality? Is dark matter against your religion?

Glad to see you're back at Fermilab with your videos Dr Don (More Please). I'm also glad to see that 'someone' finally decided (realized?) that you Physicists are "Essential Workers".
As always, Dr. Lincoln, it is a pleasure watching these videos. thank you.
I'm extremely interested in all things physics and extremely infantile in my understanding. Thank you for "dumbing it down" for me!
It's great to join the university and get a degree 🎓.
Like I can't imagine a doctor prescribe therapy for cancer without knowing what a gene or chromosome is.
theoria apophasis has very interesting things for you on his CZcams channel! I would check it out.
Just find the Quantum Duck for me, that is where all the quarks come from.

Abhijit? What kind of name is that?🤔🤔🤔. You cant be a physicist with that name...🤣🤣
This is such a great channel. Thank you Dr. Don. You should have way more than 505k subscribers!
Tell all your friends and enemies.
I love your videos. I’ve been binging them all day. Please keep them coming. You make this stuff understandable for the average person
I had to rewatch because the first time through I was literally too distracted from lack of mustache.
What a time to be alive! I am pumped for Dune and this has me just as excited.
Dune has nothing to do with physic !
Professor Lincoln is back, great. I've been waiting for more if your videos. Safe to day I wasn't the only one.
J just ran across it as a physics major working in an engineering job for almost 25 years.
Made me aware of the beauty and significance of physics again.
Thank you 👍
Probably the MAGIS-1000 will be able to detect the missing mustache. We have to wait
i love your hand movements
Physics is so amazing. I'm very thankful for your work and efforts to bring that down to the public. Please, keep on for us!
Nice video! Missed you, great to see you back! 🙏
Thanku sir for this video.
Not gonna lie, I kinda miss the bookshelf...
(And it is a good informational video, I just sometimes get stuck on the visual things)
I'm sure Dr. Don will go back to that format at some point.
I miss the moustache :-(
@@Nihilicious83 Never been a big mustache fan, so I can let that go. But the books gave things a more comfortable aesthetic.
@@Nihilicious83 Have you ever heard of Schrodinger's mustache?
I love physics and your keen fashion, Prof. Thank you for making physics seems easy to understand 😊
He's back!! Oh boy do I love these videos.
Small note : De Broglie is a tricky surname that is not pronounced as written (at all).
Even French people have a hard time with it as, the way it's said, they would write it "De Breuil" if they dif not know how it's spelled.
I'm French and I was in my twenties when I learned about it.
This wikipedia page has the correct pronounciation in audio : en.m.wikipedia.org/wiki/House_of_Broglie
In English the closest spelling might be de Broil or maybe duh Broyle.
Here's the thing about the pronunciation of names: It's not absolute. Names are pronounced according to the language and region of the _speaker,_ not necessarily the native way a person would have pronounced their own name.
I've lived and worked in Asia, Western Europe, and North America. I can tell you from my own experience that everybody mangles foreign names, even the French. When I joked to my American colleagues how the Europeans mangled my name, they said I wasn't alone. Their own English names had been mangled as well. My colleague Howard told me that when he visited Paris, the French called him "Owaar," and when he told them it was like the aviator Hughes, they said "Oog" 😂
In general, there's no one "correct" way to pronounce a name.
• Two people with the same name may pronounce it differently if they're from different languages, cultures, or regions.
• Let alone two different people. The same person might pronounce their own name differently in different regions. For example, a lot of people who emigrated to America Americanized their names, _including Einstein, Von Neumann, Antonin Dvorak, and Vito Corleone!_ 😁
That's the price De Broglie pays for international fame; the price Howard and I pay for the privilege of traveling internationally in this multicultural, multilinguistic world.
It's not done maliciously, so I don't get worked up about it. Neither should you.
Coming to the way Dr. Lincoln pronounces foreign names. (Foreign to him, that is, non-American names.)
In general, if you have to pronounce a name-any name-would you say it like a native, or the way your target audience expects it? From a practical point of view-unless you're specifically teaching them how to pronounce names-I say the latter. You're trying to get across a message, and you don't want them to get side-tracked. So it's not just names-you should also use _their_ units of measurement, sports, and pop-culture references.
That's exactly what Dr. Lincoln is doing. As an American working in America and speaking in American English, his primary target is a non-technical American audience. He definitely knows that the American pronunciations of foreign names is different from foreign (native) pronunciations. It's not difficult for him or his research team to dig up the native pronunciation. But he deliberately uses the American pronunciation-it's the reason I've mentioned earlier. _And it's not wrong!_ It's the culturally accepted practice everywhere.
His pronunciation would be considered wrong if and only if (1) It was not the commonly accepted pronunciation in his language, region, and target audience, _and_ (2) it was not the native pronunciation either.
A broader, international audience is expected to understand that.
So, yeah, it's futile to call out speakers because they don't pronounce words the way you do:
• If they're confident of the pronunciation, it's because that's how they've heard it being pronounced, and they expect the audience to understand whom they're talking about. Dr. Lincoln falls in this category. Remember, this is not an extemporaneous talk. It's a planned production-it has been scripted, rehearsed, recorded, and edited before being published. If he or his producers were doubtful of the pronunciation, they'd have re-recorded that part and edited it in. Fermi Lab has the resources to do it!
• Otherwise they already know that they don't know the "correct" pronunciation. They still need to move on with the rest of the talk, so they do the best they can, hoping that the audience will understand. They may hesitate, they may stumble, they may apologize for their pronunciation-it's really up to the speakers' individual style. For the listeners, the key is to not miss the forest for the trees.
@@nHans I'm certainly not worked up about it. The way it's spelled and the way it's said is so different that there's even actual jokes about it in France. The only purpose of my message was to convey information, just so, for exemple,people know that when they hear someone say "de brogli" said as written or something like "de broyle" it's the same guy.
There's no point in blaming someone for there pronounciation of foreign names and that was not my intent in any way.
Future is promising. Thank you for letting us know!
nope not really ,you are in closed environment with no way out and with a growing population and a decreasing amount of ressources ! and no matter what you wont break the speed of light making any hope of stellar exploration highly unlikely at least by biological humans !

Thanks Don. There was much I did not get in this one. I'll watch again.

Thank you, Don! I really enjoy all your videos!
I grow a mustache, Don gets rid of his. Thanos approves.
Its astounding how humans are capable of building these machines
If these 'scientists' didnt spend their careers building expensive toys they would probably be building weapons of mass destruction. Its safer to have them just doing maths and stuff and publishing BS papers.
@@fivish WMDs are more fun to play with.
Good to see Dr Lincoln! Nice new intro you guys
Dr. Lincoln is just the best... And so humble, too.
Wow Don without moustache! what a twist!
I wondered how long a comment on that would take. 29 seconds is the answer.
It's still there in spirit

It takes minutes off your age.
I'm here mainly for dad jokes. Physics is just gravy.
I don't think it is appropriate to make dad jokes within this context. I seriously think you don't understand the gravity of the situation.
@@MrElvis1971 Your reply displays much uncertainty. It screams for a response to probe whether it shall collapse all its fringes into a singular point mass or remain beyond the event horizon of the observables.
Speaking of observables, last night I went to look at the sunset. I was looking at the horizon and noticed the king of the birds, a Hawk. It was amazing to see the Hawk King at the horizon. It was eventful.
I love your show. Never stop. Thank you.
Awesome. Amaizing ideas and experiments . Keep it up Fermilab , and keep These videos coming, they are a gem for us physics fans.
Oh man, Don looks so much more healthy and happy in this episode! I'm really glad to see that, because most science comunicators that I follow on youtube got really depressed in the videos after the pandemic.
The more we discover, the less we know! 🤯
I only know that i know nothing. So i guess if i try to learn something i end up with negative knowledge , if the more i discover the less i know...
The more we know, the more unknown unknowns become known unknowns.
It's turtles all the way down.
That could mean you're heading in the wrong direction. But you can only speak for yourself.
Hey Dr. Don! Good to see you again!
I love hearing about contemporary experiments. Thanks for the peek.
Who is this guy? sounds familiar.
He sells "smart pills" on Infomercials
Sabin hossenfelder has a lecture coming on CZcams titled "Is Dark matter real" 😂, Don got his reply to it quite early.
Has she? A new one because she made a video about dark matter a while ago. She doesn’t think it’s real.

Read Chae et al, Testing the Strong Equivalence Principle. Dont worry about MOND, it's not needed to understand the basic idea, that the gravitational attraction between galaxies is too large to be ignored.
Your channel is one of my favourites ❤❤
You get extra points for good audio.
So many drop the ball regarding good audio reception/presentation.
I'll tell you what Dark Matter really is: A tool for people who are unable to say, "I don't know."
I have a feeling the true purpose of this experiment is to look for Weakly Interacting Mustache Particles.
:D
“They wait until they’re measured before they choose a state”
Uh huh. Riiiiiiight. This is straight up hand-waving
Good job. People have to stand up against this bullshit.
An excellent summary thanks for taking the time to explain it
🙏 Namaste
Thank you for the videos! Making unbelievable things palatable for the masses ❤️
Another great explanation from Dr Don and I have to agree that Kirsty's videos are well worth watching
Dr.Don is back to rock on!!
I could listen to Dr Lincoln read even the most boring things in the universe, shipping forecasts, and be entertained, but when he talks physics, even I get excited.
This is beautiful stuff here. Amazing what humanity can accomplish. I also like the new intro.
Great job, Don!
Very interesting video, thanks Dr. Lincoln.
Fantastic stuff! Can't wait till MAGIS - 100 is up and running!
Thank you for explaining things so well. Your videos should be in all High School & Colleges.
duuuuuuuuuuude! good to see you again!
Thank you for doing what you do. I'm definitely showing my son this video
Thank you, these videos are much appreciated
I propose that you create a Q&A website for physics. I know multiple sites are out there, but they are inefficient for the public. You are great at explaining things.
Yay Dr Lincoln is back.
This is a high-risk experiment. An all-or-nothing proposition. With a *TREMENDOUS* potential, if successful.
Glad to see you are willing to go out on a limb, in search of great things.
*Do Great Things!* 👍
welcome back Doctor Don!
Dr. Don is back! 🙏🙏

Loved this video!
I was paying attention.. Yet this stands only as a comment to endorse the spectacular opening and closing cards! Bravo!
Welcome back doc!
I'm not sure I understood everything but I do like the project. Good job. I even like the concept of beginning small(-ish) before jumping to large sizes in the detector, it makes so much sense!
Wow it seems like super cutting edge experimental physics, I am mind blown 🤯
Really great addition,
Very interesting work!
Wow! 6.4e5 subscribers! Keep up the good work Fermilab!
Dr Don Lincoln, I like this - I subscribed and I shared it! ....thank you ....
This video was very interesting, and informative. I wish you much success on the project. I have a serious interest in physics.
Dear Don: Great to see you again. take care rick
Thanks Doctor Lincoln Doctor Duffy is educational and entertaining as was this video
Thanks, Doc, always great!
This is so interesting to me, all of these questions and I really like how you explain the answers. I'm new here only have watched 5 videos, I follow a few science channels, but this one I find you're explaining better than most other channels because I think you can speak to a wide range of different age groups.
You said in this video that you do read the comments, I hope that's true and Maybe respond sometimes?
I have many questions maybe you could use one for a a video sometime. 😊
So far great channel, I will be binging you're videos as I love to learn more and more about "space" and all of its secrets 😊😊
Amazing video as always!
As a physics dropout and electrical engineer (software integration focus) in the making; I always love to keep up to date with the actual physical laws of the world and more often than not end up wondering: "How could we build something to test that", or "How could we use that knowledge to develop new sensors for robots to navigate the world"
Thanks a lot for the informative videos, and keep up the dad jokes; they make everything better!
