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.

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.

I was watching an astrophysist's video about "physics crackpots" yesterday, and one person she kept mentioning who *wasn't* a crackpot was Luis Alvarez. He kept using his physics knowledge to look at things that weren't in his field, but when he was proven wrong (like with the Pyramid) he let it go. Until he and his son found evidence for the meteoroid-extinction hypothesis. The crater that proved him right on that was found a few years after his death. I'm definitely going to want to read that book at some point. Thanks! (The channel is acollierastro, in case you were wondering)

One English pound was worth 240 old pence so I don’t know if I was getting my comics cheap or not.

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

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.

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.

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

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

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

Thank you Dr. Great explanation

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.

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

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.

@mrjava66

It could work. It depends upon if you have access to the lower levels and how deep they are. Basically, you would just need to setup detectors underground, make measurements, and then do calculations. The problem is that the most of muons only penetrate dozens of meters of rock, and very few penetrate 100s. It would take a long time to collect enough data to find tunnels. This problem is escalated by the bulk difference in numbers. A void in a pyramid that reduces the material between the detector and outside by 20% if 10 times easier to find than a void in a mine that reduces the rock thickness by 2%.

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.

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

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

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

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

Thanks for making this topic understandable to a mere cabinetmaker!

Thank you, great lecture!

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.

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

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 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.

A pleasure, as usual!

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

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

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

Well, time dilation probably kicks in...

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.

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

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.

Fascinating.

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

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?

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

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

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

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.

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

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.

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?

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?

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

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

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

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.

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 🤔🤷

What happened about muon tomography between 1960s and now?

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?

They're not using an artificial muon source - they're detecting muons that are hitting everything on the surface of the Earth pretty much all the time. Whatever chemical changes are occurring due to muons must be tiny or else we'd be seeing the effect in all the materials around us.

I think you're right that scale would be a problem. Neutrinos might be too weakly interacting, considering that a large portion pass through the entire Earth. Neutrino detectors are also really massive, just to interact with any neutrinos, and might be unable to measure quantity.
