this lecture was amazing look at the mans smile that's his passion in teaching that smile tho while explaining the stuff its all that excitement and enthusiasm in teaching us
A wonderful lecture. Thank you so much for the information and profound presentation. Maybe that Neutrino Ghosts will show us ways to reveal a lot of hidden secrets of the Universe.
Such a fabulous and interesting lecture! I love how far into the weeds it got...these details of how exactly experimental physics works seem to often be glossed over in popularizations.
This is a phenomenal lecture. I think she did a great job with the pulmonary information for those who are not already familiar with basic material. But his description of the various problems in data acquisition will absolutely amazing. Infosys circuit designer and a computer programmer and architect and these considerations that he was describing are quite amazing. I suddenly realize why LHC detectors Atlas and the other one are so huge. Among other things outside of the various devices that detect electrons and protons and photons and someone does all the number of wires that need to be managed millions of wires and getting them all from one place to the other with minimal moist and insufficiently short distances is such a difficult problem. I remember designing and kissed system for a supercomputer and problem I had was that speed of light was too slow given the length of the cables. I I had to put an absolute limit on the length on a cable so that there is a guarantee that the signal on it could be locked. And I don't think I ever appreciated the difficulty of this before. He's got me thinking about these problems in a very different way than I ever have. I can only say Bravo for a wonderfully stimulating lecture
Hi i'm not a scientist or knowledgeable on any of these things, but in supposition that all known forces in the universe were once unified, wouldn't the energy level required for that be much lower then we expect it to be, this idea came to me because of the weak influence gravity has compared to other such energy fields like electro-magnetism etc. curious what your thoughts are on this.
Great question! Beams of pions (and some rare kaons) are quite easy to produce, and also to point in the desired direction. Pions then decay producing neutrinos, which by momentum conservation, will have *mostly* the same direction as the original pions, this is the neutrino beam. Not as well collimated as the original pion beam, but still quite well collimated to have many of them hitting the detectors hundreds of miles away.
Hmmm. Why do ionization electrons travel at constant speed? They should start with some speed (i.e. kinetic energy) and from then on they should accelerate in the direction towards wires, due to electric field between cathode and wires. Or is there some effect at play slowing them down at exactly the same rate as electric field would accelerate them. Like collision with those orgone atoms (wink)?
The presenter should have prepared, rehearsed, and rehearsed again until the umms, uhhs, and ahhs were eliminated. Representing a major laboratory through a public talk to an international audience is a privilege.
Editing English typos and avoiding to treat everyone like they only have a middle school preparation would also help but Fermilab is filled up with elitist boomers so it can't be helped.
I am thinking out loud, you can compress raw data on fly with XOR functions on plc (fpga) and then create images on a large computer and compress it with lossless compression, its better to make your own optimized silicon chips instead for this purpose than using off the shelf fpga that are not perfectly optimized for application but money, yeah. I love these kinds of problems, like geometry based noise reduction, etc.
Great question! You are totally right, in that only massless particles can travel at the speed of light. In fact neutrinos are the lightest particles there are so far, therefore they always travel very very veeery close to speed of light, to the point of being experimentally quite difficult to measure that difference in speeds.
There is a danger of throwing out everything other than 'expected' events, in there is some data at a more physical level that could lead to an unexpected discovery.
Maybe due to being nervous but throughout the talk Dr. Wes is putting around 3 Ah's and Eh's into each sentence. Very distracting, get rid of those. Otherwise a good lecture.
Weak interaction Question... During Beta decay the decay energy is shared by the Beta particle and the Neutrino. The measured Beta particle has an energy that differs for every individual Beta decay. The rest of the energy is taken away by the Neutrino. The sum must be equal to the endpoint energy. But what process decides in each case how much energy the individual Beta respective Neutrino will have?

@@seionne85 No, but lots of people will see an empty comment list for a little while. Even when you see your comment added, it is not yet merged with all other comments (because that's hard to do). Just because you see your comment on its own for a little while, it doesn't mean you were actually first. Also, nobody cares, so please stop being silly.
@@DavidBeaumont i also think its completely retarded trying to be the first to comment, I just didnt understand what you meant about comments syncing. Seems common sense but I guess the idiots that post "first" are also too dense to understand that their comment sections arent a live feed
sure, but you don't need to know how a ADC works to understand the technique. Just like you don't need to know how FPGAs work or how a neutrino beam is generated.
@*Floofy shibe* Yes, in the sense that particle physicists have in mind their physics goals, rather than developing new circuitry -- although it is not uncommon that they need to develop new circuitry in order to reach faster data acquisition or triggering performance, for instance. It is just not their primary goal.
@Fact Checker Wow! Now those _are_ some fun facts! It's a real time saver not to have to check for myself too! (Which is good because I'm a busy guy with videos to watch, comments to make, etc.) I'm in your debt. 😁😸🐹
I want to know more about Dark Matter...how much it's the concentration of it in our solar system and how do we know that it doesn't interact with even itself ?
A single almost massless particle collides with 1 particle inside you. Aka nothing happens. The electrons coming from the same beta decay are a lot more dangerous.
2:07 I guess I am an elitist of sorts. Specifically, his use of an image from a Wiki site. I don't believe any site that has the word "Wiki" should be used a a credible source in any academic paper or presentation. The caffeine is correct, but as a scientist he could have captured an image from pubchem.ncbi.nlm.nih.gov/compound/caffeine. 3:02 I wish people would stop saying electrons "orbit" the nucleus and stop depicting atoms as little solar systems with electrons orbiting like planets. Those complaints, however, are minor and the lecture as a whole was very informative.
I have a hard time listening to someone speak when they constantly say ... Ah or Um every time the start a sentence. He might be very intelligent, but public speaking needs a little tightening up.

Great lecture.
Another excellent video from Fermilab! Thanks!

I realize I am pretty off topic but does anybody know of a good website to watch new series online?
@Eugene Quentin Flixportal =)
@Elisha Enoch Thanks, I signed up and it seems like a nice service :D I appreciate it!
@Eugene Quentin glad I could help :D
Neutrinos - gotta Ketchum all.
This needed to be said - don't act like it didn't...

Astonishing to see the neutrino interaction points. Something out of nothing. Almost magical!
Thanks for getting into the details!👍
Too many presentations gloss-over that.
1:04:00 Would there be spikes in activity in coincidence with LIGO detections?
Quick question, How are you keeping the logic circuit from being interfered with?
Hi i'm not a scientist or knowledgeable on any of these things,
but in supposition that all known forces in the universe were once unified,
wouldn't the energy level required for that be much lower then we expect it to be, this idea came to me because of the weak influence gravity has
compared to other such energy fields like electro-magnetism etc.
curious what your thoughts are on this.
How to catch a particle?
1) Find a guy called "Ketchum" :D
2) Let him catch'em all ;)
A Pokemon fan that happens to catch neutrinos maybe? If so then my bet is he legally changed his name XD
As an old tube guy (what we had before transistors) why not build the chamber as a triode? It would have a lot more gain to overcome the noise.
Could a particle in a quark be considered a type of resistor like in circuitry?
How do one makes neutrino beam? How you direct neutrino beam to the detector?
Great question!

Yes, very irritating to listen to all those fillers.
He just looked like a typical American who doesn't care that other people in the country, especially non-English speakers, feel...
I don't think the isue is with his research but may be English is not his first language.
Editing English typos and avoiding to treat everyone like they only have a middle school preparation would also help but Fermilab is filled up with elitist boomers so it can't be helped.
Love the thumb nail. Boo from nintendo is iconic.

What is the speed of neutrinos? If they have mass then it can't be at the speed of light.
Great question!

i studied Oklahoma at the University of Supernova, I imagine we might have much to discuss 🤔
Awesome

How to catch a ghost particles !👻
This reminded me of The Conjuring.
You skipped over how to "make" neutrinos and have them fly away in a narrow beam, kind of important.
Great question!

When you write "first" you realise that the comments sync all over the world so it's not accurate, right?
I can't wrap my head around what you mean lol wouldn't the first comment be first regardless of time zone?
@@seionne85 No, but lots of people will see an empty comment list for a little while. Even when you see your comment added, it is not yet merged with all other comments (because that's hard to do).

Also this guy is talking about one of my favorite topics, and i know it's shallow of me but I cant stop hearing his uhh and umm habit
I'm confused why a talk on particle physics has a long segment on basic circuit design techniques like ADCs
Because it is a presentation for a general audience, it is not assumed that the audience is familiar with some basic concepts of engineering.
sure, but you don't need to know how a ADC works to understand the technique. Just like you don't need to know how FPGAs work or how a neutrino beam is generated.
I do agree with you, that he spent a bit too much time on explaining how ADCs work.

Any relation to the Pokemon trainer?

TIL. Now I know Ketchum is a real surname-not something contrived for Ash to have a last name that sounds like “Catch ‘em” in Pokémon.
A to D converter?
Analog to digital converter. Converts voltage to binary.
Thankyou.
I want to know more about Dark Matter...how much it's the concentration of it in our solar system and how do we know that it doesn't interact with even itself ?
And what happens to those 25% when the neutrino does interact with us?
Get an in explainable illness ?!?!? :-O

0:59 mr ah
I think there's more ah in the video than neutrinos in the universe
Good

First again.
No you are third.
All "science" starting to sound like childish Crap...wooo this woooo that,maybe couldbe..mystary...
