"Our equilibrium state is death" Dr. P. Moriarty
Timothy Barth Like, whoa, man. Hella Deep, bro.
+Timothy Barth That's actually a very optimistic statement in a way. I mean it encourages you to keep on creating all kinds of 'mess' in your life- draw, paint, make music, dance, write algorithms, create new recipes, travel to new places- whatever kind of mess-making satisfies you deep inside! I mean the idea of life as an expansive journey and not a boxed, contained one.
I agree
Could listen to this guy talk all day
The enthusiasm of this guy is fascinating.
Who else thought we were going to learn about a thought experiment called "Schrodinger's Theater"?
Noone else.
I read Erwin Schrodinger's What is Life? because it was recommended by Philip Wylie (an important but now mostly forgotten American author) in "An Essay on Morals," which despite the title, is his philosophy of the sciences . It is, just as you described, and easy read, but a profound book...
What is life?
Baby don't hört me, no more.
I might want to read that book, seeing how Phil is so fond of it.
I really like the style of this video. One person, really knowledgeable and (most of all) passionate about a very specific subject.
This guy gets so excited about what he does. That is great.
How can you dislike this video, i just don't understand, its incredible were being given this for free!
I love Schrodinger's "What is life" and "Nature and the Greeks" Great books \m/
My favourite Sixty Symbols professor.
The Closed Captions add a whole new dimension to this.
As a biochemist, embarrassingly I was unaware that Schrödinger was involved in biology. Will have to hunt down a copy of What is Life. Fantastic video.
This morning I found out that I was accepted into Trinity College to study Theoretical Physics, and will be starting the course in about a month. I was also in Trinity College earlier today to see the Book of Kells as a cousin is visiting from England. And now after just arriving home and turning to youtube a see a video about a lecturer of theoretical physics in Trinity College by a person visiting from England, with reference to the Book of Kells. Now thats a coincidence. Thanks for the video.
This is great, I've had almost all my physics lectures in this theatre. Thanks for making a video about it!

I don't think you mangle the English, I think your accent adds a glorious new dimension to it :)
"tree" LOL, just beautiful!
Nice, I really hope to visit that place one day.
"Equilibrium" has to be nominal, an aspect of QM-Time modulation, but that is beside the point for large shifting of equilibrium points in physical embodiment.
Wow, just wow...I think this is my favorite sixtysymbols vid.
Schrödinger. After my course Quantum Mechanics I he's become one of my personal heroes.
i get so much more out of him when he's calm :D
Love u Prof
I did, and it confirmed what I thought, I can even post sources.(Unless you have an unusual accent...)
Word -> AmE: /wɜrd/ BrE: /wɜːd/ Source: dictionary.reference + oxford's dictionary
List of round vowels of RecPron: u:,ʊ,ɒ,ɔ,ɑː
This is the best I can do to get close to your statement is this. RP in wiki:"/ʊ/ as in foot is also written /ɵ/"
Anyway, take a chill pill.
Grabbing the book tomorrow, driving an hour each way to the only bookstore that carries it!
@IcEye89 It is indeed still in use. Most physics lectures (roughly 80%+) are held there.
There is no ö-sound (IPA: /ø/ in this case; /œ/ is the shorter one) in English. I guess you're referring to the long vowel /ɜ:/ as in "bird" or "dirt". Opposed to that sound, /ø/ is tenser and has lip rounding. It sounds quite a bit different from /ɜ:/ and could actually be described as an /e/ plus lip rounding; just like German ü has less to do with /u/ than with /i/, since it's essentially that plus lip rounding.
So... When Brady, and Moriarty are in the Schrodinger Theatre filming this, do we have to think of them as both dead and alive until we view the video?
we must put sianide first :DD
I thought Sherlock Holmes killed Prof Moriarty?
Someone might have placed in the theater a poison bomb rigged to a decaying material. If that's the case then yes ;)
No.
So an Austrian, Irishman, a theoretical physicist, a mathematician and a philosopher of science walked into a bar. The bartender said "what can I get you, Schrödinger?"
As always -- thank you for a thought-provoking and entertaining video!
Love it. One more book for the reading list!
This is where I attend all of my physics lectures. I feel happy now.
For the Americans in the audience: 'gob' = mouth. ie 'gob smacked= hit in the mouth. 'Gob stopper' (from Willie Wonka) = a candy that fills the mouth. 'Goblin' = a monster that puts you in his mouth (to eat you). I mention this because 'gob' is rarely used in American English.
Loved the fact that I had no clue that the context and history would serve as a build-up to the amazing story at the end!
One question though-
What was the reasoning that led Shrodinger to claim that the fundamental particle of light ought to be as complex as the illustrated manuscript in question? Was it that only an organism made of such complex particles be able to make such complex artworks? Or was it that complex information can only be embedded in a complex manner, such as the configuration of lines and colours in a page of that manuscript? Or was it something else entirely?
If you compress a file using for example zip, you'll notice that some files compress better than others.
Large input files don't always lead to large zip files. What determines the size of the compressed file is the amount of information of the input.
Life begins with a single cell, and sprawls out to create beings of great complexity (what physicists call entropy).
That complexity must be encoded in the initial cell in a way than can be passed on generation to generation.
Therefore, that encoded message must contain the same amount of entropy as the adult being (not counting environmental influence from after birth/hatching/sprouting). In a computer file that entropy can be calculated from the patterns of the 1s and 0s in the file. In physics and in biology, the building blocks are atoms rather. But the principle is the same.
That was what Schroedinger was trying to say. He was assuming macroscopic objects couldn't exist in superposition, especially a living "observer", but evidence implies macroscopic objects can exist in superposition the same way a quantum object can.
As i've understood it, Shrödinger's cat is actually meant to be a ridicule of Niels Bohr's theory of superstates in quantum particles, which Shrödinger thought illogical
I was in this theatre yesterday....
To me a modern version of this mood/spirit is the book "The Vital Question" by Nick Lane
BRAVO!!
Hehe I find it amusing that the ruler of a country right next door to the UK is called "Tea-shock".
Thanks for the video!
I like the way Irish universities judge applicants just based on qualifications.
You all missing the point; the cat is definitely inside the box. The question is whether the cat is alive, or not! :P
@john37309 you're welcome! :)
Schrodinger came up with his equation while he was deathly ill and from almost nothing but intuition. The proof is a lot of bits put together in his mind. Dirac may have had his matrix formulation, but Schrodinger made the popular equation.
You have teachers, and then you have TEACHERS! We could use a lot more TEACHERS like this one!
No she claimed a double-helix, I should've have mentioned my source. I got this information from my 11u biology course textbook or course pack.
just bought the book
Aperiodicity. My word for the day. Thanks guys, great video!
Actually I really loved the piece..
Phillip, the "Mad Professor" Martin Poliakoff and all the other people at Nottingham University who contribute to sixty symbols are marvellous.
No arguments there
:-)
If you lecture there, and I don't attend the lecture, would I both understand it and not understand it at the same time?
personally, i find your accent endearing and i love hearing you talk. hope you dont find that all too frightening :D dont bother changing your pronunciation hahaha
@Moriarty2112 OK, thank you for your answer. It seems like the word "entropy" can mean many things. In data mining (part of my field) it basically means information retrieval efficiency. Low entropy = high efficiency.
If this guy was my teacher..
I'd be surprised as hell, how did I get to college?!
6:13 Watson and Crick who stole the idea from Rosalind Elsie Franklin.
en.wikipedia.org/wiki/Photo_51
+Seedeng Jawn franklin was an experimentalist and watson and crick were theorists
They nicked a photograph via Maurice Wilkins. It's disappointing all 4 weren't on that paper.
Ok, that's one of the most clever comments I've ever seen on TH-cam. Cheers!
I only watched this video to hear Prof. Moriarty's voice/accent. I can't help it.
@noodlescratcher Ahh you were the disliker, I think considering Schrödinger did make a considerable impact on science and was a good figurehead means he's more than legitimate to be discussed. This series of videos is supposed to be accessible to all, if interest is sparked by this video in some people they're more than free to look up similar physicists.
As a biochemist I really can't give you physicists the ideas Schrodinger discussed in this lecture (if it were Gamov... Maybe). I'm not saying it wasn't influential, but he certainly wasn't the first to look at biology this way. I hate to bring up Pauling (I REALLY do, so many biochemists misplaced their brains near death), but he and his colleagues across the world beat Erwin by at least 5 years.
That aside, Schrodinger was a poet scientist, and physicist are lucky to have such a forebear.
@Moriarty2112 Hi Philip! Actually after I'd wriiten that I listnened to your piece again and loved it!
Hmmmmmm the umlaut on the o, I was thinking about the vowel sound. It's just like the sound in "bird" or "turd" or "herd" so perhaps thinking about Schr"ur"dinger might help? I don't want to put put a turd in Schrödinger but it could work for you! Love all the work that you Brady and all the professors make at Nottingham. Fantastic.
All the best Phillip
@Moriarty2112 I actually like your accent. It's something I don't hear often but it's... nice to listen to you speak.
Then say that. You won't get people objecting if you try to get the comments back on track instead of whining about the comments that are off topic.
that defeats the point of the cat experiment. its to show that the two types of physics do no "work" together, not that the cat or students are "both dead and alive", which is what i also thought for way too long
I wouldn't call DeValera an amateur mathematician, he lectured physics and mathematical physics at National University of Ireland Maynooth.
If this guy was one of my teachers, then I would like school a whole lot more.
These videos are really great. If only i have an internet connection that is blazing fast, I could've downloaded all of these videos. Mr. Brady, do you have a downloadable compilation of all your videos?
What i do with this stuff is that i download them, convert them into mp3 format, put it on my phone, and listen to it before i go to sleep. I made them my playlist too. Professor Moriarty is a great physicist and explains everything concisely. I wish i can download all of this in torrent.
The "ö" in Schrödinger sounds like the "e" in nerd. Don't know why so much english/irish/americans struggle with its right pronounciation.
+11Kralle To anglophone ears the difference between Schrödinger with an ö sound or with an o sound is very subtle. When I hear German/Austrian people say Schrödinger (I had a particle physics professor who was either Ger or Aus), It just sounds like 'Schrodinger' but with an accent.
Areo Hotah
Of course, but if you hear a native saying "Schrodinger" (be it a german an austrian or a swiss) it will not sound like "Schrodinger" spoken by an english native speaker. Besides: one from Saxony will sound very different as one from Swabia.
(btw:the "o" in Schrodinger would sound like the "o" in "home" - yet sometimes the "o" can sound like the diphtong in "haul").
So much from Germany...
*pronunciation.
wait, if it is the non-periodic nature of DNA that makes it so effective as an information storage unit, wouldnt it be possible for the newly discovered quasi crystals to be used in much the same way? specifically the interesting trait is that they are both repeatable with variation inherent in the design
Yes, it is in a superposition, but that does not mean the cat is both dead and alive. it means that on a quantum level, the cat is in both of the two possible states at the same time. but like i said, that still is not the point of the thought experiment. it is to show how these quantum "rules" do not apply to everyday objects because while the cat exists in both states on a quantum level, it clearly cannot be both alive and dead in the real world, which was the point i was trying to make.
Come on, my personal favorite is prof. Bowley, but I think all of them are great, no exceptions.
@Crazyegg1234
it's just some TH-cam counter glitch that happens every now and then... i THINK when there are suddenly too many views around the world the "views" gets messed up but "like/dislikes" don't
Cool, I'm studying aperiodic patterns at the moment!
If you're in that theater, nobody knows if you're dead or alive till they open the door.
Hey that's where I learn stuff, cool!
If it's the Schrodinger Theatre, do they have to project the image through a beam splitter, bounce the two beams off reflectors and combine them in a half-silvered mirror to get a clear picture?
YEEEEEEEESSSSSSSSSS......
Thanks, I wish I'm more familiar with the School of physical Sciences than I am, considering my topic, maybe as my project develops I'll be more in contact with the school. I'm in the school of Biotechnology.
Thanks!
Question: Can there, or are there any more colours then the ones we already know. Just trying to think of a new colour is mind boggling
I have 5 lectures every week in the Schrödinger Theatre, those seats aren't very comfortable.
Judging by the age of this video I suspect the cat would be more dead than alive now ...
+Jacob Carolan made me giggle
:(
I read What is Life. I almost understood some of it.
@jombo222 schroedinger's cat was meant to be debunked, that was the point.
oh, I was expecting something similar to Hilbert's hotel.
Lugmillord same omg 😂😂😂
@ramchand45P6 If you look on iTunes U they have a podcast channel which, I believe, will include all their videos which you can download in bulk.
Then that would imply that you know the state and location of each student. We are referring to the students as a unit. All students are alive and dead until you poke in your head and collapse the reality down to a single possibility which coincides with your reality.
.
What I hear being said personally is ShoDingner.
I don't mind it.
Typo in the description! :O
Otherwise great vid! :D
This dude is so cute.
Don’t you think Claude Elwood Shannon deserves a video?
@noodlescratcher - it doesn't matter who is smarter, it is who accomplished more. Few people accomplished anything as great as Schrodinger. Even so, you need to understand who they are to understand what they missed. There are many stories of scientists unable to accept something because it contradicted their intuition. Schrodinder is so great because he got past that. Einstein had a hard time with quantum, yet his determination to understand it affects the field even today.
8:05 Watson and Crick did not discover the structure of DNA either, it was Rosalind Franklin.
- ... Taoiseach-
- What?
- Taoiseach.
- What's that?
Oh, HONESTLY.
sealbones Seems esoteric to me.
Tea-shock?
I had no idea how taoiseach was pronounced before watching this video.
Ummm....at the time that I'm writing this, the video information says that video only has 302 views, while at the same time it has 349 likes, and 1 dislike.......I'm pretty sure that doesn't quite add up....
Will do. I'm not entirely sold on the waveform collapsing upon observance. This sounds more "believable" not that its a prerequisite that anything has to be believable to be true. I also remember a sixty symbols video on the many-worlds interpretation but I cannot link to it here. Google "quantum mechanics is an embarrassment" to see it.
Thanks :D
Have I heard of Schrödinger's cat or not? I won't know until I open the box.
6:15 Watson and Crick did not discover DNA, it was Friedrich Miescher.
Indeed, they found the correct structure, but give the guy a break! On some semantic level you could still argue that they did 'discover' DNA as we understand it today.
What's in the box, Schrödinger?
Noted mathematician Daniel Biss often mentioned in vlogbrothers is a politician.
I thought Schrodinger did not even interpret his equation properly as being a probability result. Einstein went off in a different direction vs. quantum mechanics. Is that what happened with Shrodinger too?
@Moriarty2112 Thanks for the clarification Philip :)
So at least someone can still figure out “what is the meaning of life?”.
