CAT scan actually stands for computed axial tomography because it scans in axial planes to the object not AIDED like you said. I’m a radiographer so this stood out to me is all. Keep up the good work. Maybe one day we will use muons to scan patients.

Are we just not gonna talk about Dr. Don's shirt because he clearly put a lot of thought into this.

In Gießen we once did a show where we displayed a few Röntgen Original instruments. His grave is still there.

Even cooler, scientist in Japan recently made a GPS system using Muons. The technology is similiar to regular GPS, but using Muons can be used where radio waves can't punch through, like underwater or underground.

Mummy's curses are concerning. Dr. Don wearing those glasses was terrifying.

Thank you Dr Lincoln! And thank you Fermilab! I'm just a regular guy who works in a factory, but the nature of reality is very important to me. I appreciate you bringing this data and these ideas to people like me. Thank you!

He says 'skid-mark' twice with a straight face.. A true educator, and a legend. 🙏

Oh Dr. Lincoln, how I miss your presentations and teaching. You were particularly missed as I tried to listen and understand the Muon g-2 Scientific Seminar 2023 presentation. Couldn’t get much of a toehold for understanding. My take always (before clicking away) were: more than 100 PhD students were writing their theses on the g-2 work they had done; and there was a finding in agreement with a BNL result to 4.2 Sigma, not quite 5, but perhaps evidence of “new physics”. Hope you are well and, working on a new playlist. Please, please, please. 🙏🙏🙏 My best and many thanks.

Luis Alvarez was such an amazing physicist. From the Manhattan Project to creating the theory that a meteor killed the dinosaurs. Check out his autobiography: Adventures of a Physicist for a great read.

CAT scan stands for Computerized Axial Tomography

He's a decade younger than me. My comic books only cost 12 Cents, except for the Giant issues I had a hard time finding enough deposit soda bottles to buy.

Thanks for providing links to the papers, something I wish more KZfaq channels did, they are real time savers. Just one of the many reasons you are the best.

The idea of using muons to probe the interiors of storms is brilliant.

Superb presentation that illustrates how the scientific research at Fermilab is serving multidisciplinary needs around the world.

LOVE everything you post, Dr. Don!

Awesome material indeed. The opening and closing cards too are breathtaking!

Don, those X-Ray Specs were awesome! LOL you did look a little creepi, but still, great way to wrap the video! And the video was as always, fascinating, thank you for the things you share from the world of Physics!

NICE XRAY GLASSES AT THE END! THAT HAD ME ROLLIN!!

When I was a kid we had this joke: “Do you know the germans invented a device that allows you to see through walls? It’s called a window”. It was funny when I was six years old.

Dr. Lincoln, I request you to wear those X-ray vision glasses in every future video from now on.

It wasn't until I got older and found out how xray imaging ACTUALLY works that I realized just how truly preposterous xray specs are. In order for them to even have a hope of working you'd ALSO need a source of XRAYS behind the subject you're trying to see through.

Of course, the pun with the t-shirt; Pink Floyd's Dark Side of the Moon. Looking through pyramids is one thing. Looking through celestial cheese is another.

Thank you for your coverage. Please consider including the recent discoveries and future plans of the muon guys. I know they have box of the chamber above the main entrance, but it seems they’re in an uphill battle to explore the other empty cavern discovered above the great hall. Thanks for the vid.

Thank you Dr. Great explanation

Dr. Lincoln, that's a great look for you with those specs! 🙂 Please wear them during work and let us know how it goes 🙂

Thanks for making this topic understandable to a mere cabinetmaker!

They're using this technique in the Oak Island program as well. Nice Shirt btw. I have one of those too. :)

It would be cool if you could use some sort of decay rement to do something similer with particles coming from the core of the planet. Slightly more realistic i wonder if you could use decay products closer to the surface to map caverns and mines. Living in western PA I have 2 and possibly 3 layers of mines under my neighborhood but non of the maps match up.

A seriously cool topic from one of the coolest Physicist I know!

Glad to see a new video from Don. It's been a while. How about doing a review of the movie Oppenheimer? There are a lot of threads to unpack from Oppenheimer's career and the Manhattan project. Maybe focus on one aspect of the physics. The most interesting to me is how Enrico Fermi got the first nuclear chain reaction to work at the University of Chicago. Or how about Edward Teller's alarm that a nuclear chain reaction might not be able to be controlled? Hans Bethe and colleagues showed that a chain reaction would not run away. What a controversy that was.

Luis Alvarez was a boss. Just like you, Dr. Lincoln!

That's great, while you're in Egypt, please scan the base and underneath the Great Sphinx, there are secret rooms below it. That would be a great discovery. 😊

Thank you Dr. Don! As always, a lovely clip 😊

Don in those specs should be Fermilab's profile pic.

Thank you, great lecture!

Perhaps a few images of the science equipment? Am I the only one wondering how you detect muons from all directions of a pyramid?

An excellent video from Don on muon tomography. Very well explained.

A pleasure, as usual!

Dr. James Xavier would definitely like this video.....

It's a good thing to have the flashing disclaimer about classified information. The lab director is the least of the problem when the FBI is alarmed.

Hey, I have a question about your video about why light travels more slowly through a medium.....so light exerts a force on electrons. If the electron feels a force from the photon then the photon is expending energy to move it around? If that's the case wouldn't the light red shift slightly? And if that's true how do we know that distant light we see is red shifted from the expanding universe instead of slowly having its energy sapped from electrons?

Surely it would be simpler for Scotty to give a torch to a red-shirt and beam him inside the pyramid.

thanks again for an inform video - ??? given that it takes the average person around a second to react while driving then they have traveled 35ft at 35 miles per hour if I remember correctly :: how would they react at faster speeds travelling through space - how would they not have a collision at speeds nearing half light speed ? curious thinking

Fascinating.

Cool t-shirt Dr Don! Are you wearing it because of the physics or the album?

Is Fermi lab involved in the muon tomography of Oak Island?

How does a muon detector look like? Do you have to move it around the pyramid to get the big picture?

Would you be kind enough to show us the apparatus and some images.

That finding was published in 2017. What have you guys been up to since then (regarding the pyramids)?

Can't make a Muon source that is relatively compact using a Radio Frequency Quadrapole? That wa one of the spinoffs I remeber from my work on Beam Experiment Aboard Rocket.

Another fascinating video Dr. Don! Those muons must travel at an extremely high velocity considering that they only last two-millionths of a second! 🤔🤔👍👍

But if the muons are coming from above, where do they put the sensors? Do they dig under or into pyramids, if they don't have accessible cavities?

Hank you. Can there be a series on some of the projects that are using Muon Tomography and their findings?

Can this muon tomography detect perpendicular beam of photons? Do beam of photons detect bypassing muon?

LOL, I bought those comic book X-ray specs back in the early 80’s, when I was a kid! I was really hoping I could see people’s underwear(of the lady undie variety specifically). Needless to say, they were just really crappy sunglasses. I was also duped by Sea Monkeys…there was no kingdom to rule over, just goofy brine shrimp….and I also got that Charles Atlas “stop getting sand kicked in your face instant muscles” kit. The kit actually never arrived, heh heh.

Sorry if this done already, but what does it say under the DSOTM logo on your shirt? Thx! :)

I'd like to scan my refrigerator and discover a hidden pie compartment.

Oh my god, I found the KZfaq channel of the lab where Dr. Pemberton and Dr. Campbell came from! ✌🏻😅😊

You made an analogue about a fast car's breaking skidmark. This a reference to Wirtual who's obsessed over these muon tomagraphy because the great pyramid? :D Fun if that's the case. If just a coincidence that's also fun though. Love your content.

Carl Sagan would probably have become an archaeologist if we had figured out this technology when he was a kid. This is some exciting cross-disciplinary tech.

Dear Dr Lincoln, can you make a movie about the Abraham-Minkowski paradox? It seems that it is a fascinating paradox which tells us a lot about the interaction between electromagnetic waves (photons) and matter.

You look slightly older than me… when I was little and reading those comics, they were 15c and “still only 15c” the .25 stuff came later in the 70’s…

2:35 As everyone knows, red cars are the fastest cars. Why don't they make rockets red? It's free energy!

You guys should something on UAPs

Thank you for All over the years. I come to you Dr. Lincoln, looking for clarity and detangling of a new theory about the origin of the Universe. Recently I listened to Dr. David Kaplan’s, Dark Matter: the next frontier. I liked and had also listened to Prof. Neil Turok’s, talk about his new and simpler theory about the origin of the Universe. He talks about the “… all observations are consistent with just 5 parameters…3 for matter or energy content [and] 2 numbers for the geometry…” ???? In a recent presentation by Prof Turok, “Explaining the simplicity of the cosmos” Apr 20, 2023 on the AlbaNova Colloquium Channel, @32:32 he talks about left-handed and right-handed neutrinos and how they are a solution to the “Dark Matter” problem. ????? Could you or Dr. Duffy or even perhaps Dr. Kaplan, offer some insight into the handedness of neutrinos and they might be the solution to the “Dark Matter” problem?

What a coincidence! My father and I talked about this just recently!

I’m still waiting for my flying car.

What happened about muon tomography between 1960s and now?

excellent

Fascinating. I'm curious to know how Muon detectors work, including how they know the direction from which the Muon is coming.

Clever.

Dear Dr. Lincoln, if I'm interpreting correctly, then the muon could also be used on volcanos before they erupt? Without any molten substances the muons should come through, but with lava etc. they dont. Thus --> alert! Is this correct?

Love the glasses!

Thank you.

Kool T-shirt, Dr Don! Waiting for you to reveal yourself as a Dead-Head. And please don't ever wear those "glasses" again - it was very scary!

Love It

Does a nutrino fit's the bill ? From what I understand from this video it does .. more or less ... For bigger objects probably as nutrino interaction is weak ?

👍👍Thanks!

Forgive me for not reading the papers. It took me 10 days just to find the time to watch this video. But the illustrations gave me an idea... I was wondering how they could have gotten detectors under the pyramids, and couldn't understand. But if they did their reserch at the right time of day, they could catch large concentrations of Muons moving parallel to the ground (from our perspective). Is that what they did, or am I overthinking this? Side note, why do they think this chamber is for stress relief? I don't recall ever hearing of any theories that there needed to be hidden voids in the pyramids for architectural reasons 🤔🤷

7:07 How do you find rooms, both plural and/or filled floor to ceiling with things that react like stones?

Dr. Don, CAT scan is Computerized Axial Tomography, not Computer Aided Tomography.

Question, your shirt got me thinking. If we pass white light through a prism, we get a break up of all the light colours that make white. Q... What happens if we pass all the colours through in the correct order, do we get a beam of white light out the other side?

Is the muon production so predictable that you can take it for granted? How long do you have to stay with the detector on each location to get a significant measurement?

If Marty has crashed into that Rolls Royce we would have flying cars and holograms already.

A fun fact is that we can make a working muon detector at home

Nice T-shirt. How many were alive when that album came out?

God bless you all...........i love this body of work.............does anyone know of a yt channel that is as good but covers astrophysics but not theoretical book selling bs but real astrophysics and talks in laymans terms.........gods bless

Those X-ray glasses didn't work worth a squat.

2:30 Traveling at high speed... on the wrong side of the road!

Here's a little experiment I told Garrett about years ago , Hydrogen "talks" to hydrogen. That means if you put a Hydrogen container with the exact same dimensions as another hydrogen container, in two separate rooms, you can eves drop on any conversation by listening to the containers! Garret has proved it works at least Halfway around the planet ;-) We call it "Proton S.R." , It's the reason CO2 heats up when you are running Centrifuges near by. **EINSTEIN**

Wish i could I come study it with you guys. Want to get I to physics don't know where to go

Hello Imam hossein be with you

Wouldn't electron displacement make it problematic for examining things? Displaced electrons likely would cause chemical changes to occur.

You're a youngster Doc, comics cost 12 cents when I started collecting them! ;-)

But…. what did Don discover at the dark side of the Moon?

But cosmic rays comes from all directions so I think scientists must also calculate how many cosmic rays enter at specific direction

Please, Don, don't wear the glasses to see into our homes. Thanks.

Now that explains why my muon detector finds so many around my skull.

What antimatter is for? Why universe need it, how it would be if antimatter doesnt exist??

What does a muon detector look like? How large is a muon detector used to detect hidden rooms in a pyramid? Must be really big?
