Oh thank science!
That's not a marriage, that's a Quantum entanglement 💖
😂
OMG!!..😂😂
ding ding ding!
Metaphysical cringe.
😂 absolutely right
I'd absolutely watch a 45+ min version of this discussion, it was really neat
Damn straight!
@@kellyjackson7889 same
Yeah please ❤️🙏
Throwing my hat into the ring to say I'd watch the full video too.
YES! Please make it happen.
She is like „Question clone, Platinum edition“.
I mean she‘s not just asking questions that support your point, she challanges your point.
Question clone Uranium Edition lol
Oh god, this discussion went beyond what I expect for a usual discussion of Quantum Mechanics. Your wife asks really honest and really good questions that even the regular physics students don't ask. This was awesome.
"...before this turns into a 45 minute video..." WHAT IN THE WORLD WOULD BE WRONG WITH A 45 MINUTE VIDEO OF THIS?!?!?!?
Yes! I agree completely!
one can literally feel the fear that we won't like (his interaction with) his wife :) but what we really didn't like was the abrupt ending of this great discussion!
@@steefant he doesn't care about our reaction, he cares about his wife's
I could listen to hours of such an exchange. 👍
It would get fewer views.
By stopping at a quarter of that length, the 45-minute version will get more views than it would have without this "warmup."
Fred
What do you know about quantum mechanics?
His wife: not much
Physicists: same here
😂😂😂
So true
@@johubify he said if you think you understand QM, you don’t understand QM
@@itskelvinn i know buddy, just twisted it my way
@@johubify lol
If physicists communicated like this to the general public there would be a greater understanding and support for the basic sciences.
I disagree. It's important to demonstrate key experiments and talk about how to interpret the observations, what assumptions are being made, constructing models consistent with the observations. Sometimes assumptions aren't obvious even to the physicist, and fresh perspectives of students may bring them into clarity. For example, the famous Compton scattering experiment is thought by mainstream physicists to have proven that matter is particles, not waves, but it really showed only that matter isn't classical waves.
@@brothermine2292 Even without key experiments demonstration it is important to give people the correct non-confusing explanation. We can show and demonstrate multiple quantum mechanics experiment and rant about what it means missing the key points. The key point being the predictions, which are tested with the experiments. Quantum mechanics is not something produced by higher beings that forces nature to work in weird ways. Quantum mechanics is our model(made my humans) of the nature that allows us to make accurate predictions about things we actually measure. It is not exact, there are limitations and assumptions made on the way. Quantum mechanics just like any other model has its boundaries, beyond which its predictions would diverge significantly from the observations. The interpretations are not that important and answers they are trying to give are useless, because the theory itself isn't applicable everywhere. It is very important to make distinctions between theoretical descriptions and real world. When physicists talk they have implicit context about working and making predictions within some model, while a regular person listening thinks they talk about real world.
@@linuxgaminginfullhd60fps10 : I disagree. First, for many physicists, being able to calculate reliable predictions is indeed "key" as you say, but it doesn't logically follow that the basic QM experiments should not be presented when teaching QM to non-physicists or to physics students.
Second, although it's been many months since I watched this video and I may have forgotten most of its content, I think it didn't attempt to teach Nick's viewers (nor his wife) how to make QM predictions (which would require teaching some math), and I think learning how to calculate QM predictions is not what most of his viewers and wife want.
Third, many physicists and philosophers of science during the last couple of decades have rejected the "shut up and calculate" mantra (which was useful to keep physicists productive during the Cold War arms and technology race) and are interested in improving the models and trying to find the best model. You shouldn't try to dissuade people from being interested in the true nature of reality just because you personally lack curiosity about it.
It seems quite plausible to me that the strategy of scrutinizing the QM models' assumptions is more likely to lead to fundamental advances, after the strategy of "shutting up and calculating" predictions has already finished harvesting its low-hanging fruit. Presenting the experiments and reconstructing the assumptions and arguments that led from experiments to models seems like the best way to expose unstated or flawed assumptions. The history of science shows that discarding flawed assumptions has often been the way forward.
Dude you gotto upload the whole conversation. The analogies someone who doesnt fully understand qm comes up with are wonderful!
When she mentioned spin, quoting every physiscist trying to explain it: it's like a ball rotating, except it's not a ball and it's not rotating.
Got a ❤️! Yay!
The more I try to learn about spin, the less I understand it.
Now she mentioned splitting hairs, these physics expectations feel really suspicious..
@@sgringo It is basically an intrinsic property that a particle cann have. This property is equivalent to a property that a spinning particle would have, hence the name spin. The property 'spin' directly follows from the mathematics (Dirac equation), that unifys the wave equation for an electron with special relativity (this unification was done by Paul Dirac).
It has some of the attributes of classical spin.
Him talking to his wife about physics should be a channel of its own!
Agreed!
Definitely merit to this because she's a great case of the "bright layman". Smart enough to ask the right questions, but still ignorant enough of the subject to drive the conversation.
Agree
Absolutely agreed. Make it happen Crazies
This was pretty great! I wouldn’t want all my Nick Lucid videos to be in this style, but I’d definitely like SOME of them to be!
At college, when our freshman physics course reached the introduction to (special) relativity, the prof told us in lecture that it was often said that very few people *really* understand relativity.
He said that isn't true - lots of people *do* really understand relativity.
He said that what hardly anyone *really* understands, is quantum mechanics.
I applaud you for making it more understandable.
Fred
Nick's wedding:
Reverend: "Do you take Nick to be your husband?
Wife: "Yes, and No. Let me check on the cat in this box first."
You two are adorable. Watching you try to be in “science mode” while your brain is distracted by her cuteness is so damn wholesome.
She asked clever and interesting questions, and also gave many good personal opinions.
I do want to watch the rest of your conversation, it’s fun and kinda inspiring.
I was going to post to say the same. She eloquent and succinct about how she phrased questions and reflected her understanding with apt analogies.
She's a scientist herself.
Yes, please, I'd love to see the rest, too. It gives some interesting insights.
@@cleitonoliveira932 yes she is herself a biologist if i am correct
@@yatharthpal4201 Biology is complicated in a whole different way from physics. So, yeah, great to see this conversation.
BTW: I love her comment about science and predictions. My, even more sweeping version is "Everything we know is 'just' models all the way down".
I wish I'd find someone who'd listen to me like that when I'm talking about Physics and never seem like they're bored. You're a lucky man.
Your wife is a good representative of the general questions your audience might be asking. I'd like for her to chime in with her thoughts every now and then!
That was cool because your wife has the same level of understanding of most of us viewers. Yeah would definitely like to see the rest of this conversation.
Maybe he doesn't want us to see it because it was to embarassing for him? :)
I would say she has a over the average understanding.
@@Aufenthalt I think that's what he meant; the average viewer probably has an above average understanding already.
Like having a Bardy Haran in the room.
Except she is a freaking genius that fully grasps what he's trying to say as he's saying it... i would need to ask follow up questions clarifying what he said constantly.
I want to hear you chat about interpretation of QM!
yes! i'd like to hear about the copenhagen vs many worlds as well and the dr's take on it.
Wow! I've somewhat tried to learn quantum mechanics for years by watching different videos explaining what all the language means but this 11 minute video did a better job than anything I've ever seen! Please do more, I love this format. The explanation of superposition was the first time it ever actually made sense to me.
Your wife is really smart in the sense of asking great questions and putting arguments!!
"we'll get to my personal opinion later on "
later on:
"well that's it for this video..."
It'll be in the follow-up.
Nick didn't specify how much later.
@@ScienceAsylum please fully comply with tv show etiquette and start the next episode with a nonsensical montage of random shots from this video. Don't forget the "in the last episode" voice over.
@@adb012 tru
@@thenasadude6878 Don't forget "and now, the conclusion"
Upload the rest!! Love this type of format, I find it easier to follow stuff when there's a discussion more than a monologue of information, particularly if one person in the conversation is asking the types of questions I would think of listening to the same thing.
I'm really liking this format for quantum mechanics especially.
I really loved this video. I think more scientists should do this, talk to their loved ones about science. It feels so human. Excellent job!
Honestly, it really helps that your spouse stops you and challenges you in ways that a non-physics person wood. Please upload more stuff with her in there! 🙏🏿
This was beautiful, biologists being biologists and physicists being physicists.
Does this mean the superposition of them as a couple is a ...... Biophysicist?
We also need a little chemist/mathematician in the asylum.
I wonder if their daily conversations sound like: Honey, can you cause superposition of particles freely distributed over the carpet to colapse by measuring their exact positions with a vacuum?
@@totherarf Does that mean that biophysicists become either biologists or physicists whenever they are measured?
That fits pretty well with my data ;)
@@totherarf
That's great....but... :-)
A couple consists of two entities and superposition is about one entity and one state (encompassing many classical states in a probability distribution). This would be more like an two entangled particles (entanglement) with a spin (male) and another with a spin (female).
I really want to hear the entire conversation
Your clarification on the tree/forest analogy tells me what kind of person you are. You're a good guy.
I don't speak for everyone, but it's never a bad idea to include the entire conversation, especially when the depth of the subject matter is Needed in order to explain things fully. Plus, anyone who has subscribed to your channel is more than happy to watch longer videos, cuz we've come to not only enjoy the way in which you frame things, but just you in general. So I say; Make em' long.., Make em' often, and we'll decide how much we watch ya' dig. Thanks Nick, glad to have you in my rotation of knowledge, cheers.
Physicists really need to invent their own language. Every physics lecture starts with "we call it this common term but it's not actually doing that, but it's got properties that are similar to this term so we call it this term."
Thats why I love biology. We just dragged Latin into a dark alley and beat the hell out of it and took what we wanted.
Biology has a way longer history than quantum mechanics, so this explains the reuse of latin.
Biology also has a lot more stuff to explain. Physics revolves around very ancient concepts, but it's scope is way narrower
Oh boy, I can't even begin telling you how much I agree with you! I want all specialists to create their own vocabulary, and stop repurposing words they borrow from everyday language!
Just the other day, Neil deGrasse Tyson was going on and on about why you should say "mass" instead of "weight" in sentences like "What's your weight" or "I've gained / lost weight." I kept screaming at the screen that in everyday English, "weight" _is_ correct! "Mass" means different things to different specialists-doctors, musicians, economists etc. I'd love to overhear his conversation with his doctor about his weight. Or see what he writes on forms that ask for his weight.
Indeed, medicine did a good thing by bringing in words from Latin. However, not all of biology did that. Botanists, unfortunately, did the same lazy thing like physicists. They say that-among others-cucumbers, eggplants (brinjal), and okra (ladies' fingers) are _fruits,_ but apples, pears, and strawberries are not. Huh?
Sabine Hossenfelder likewise said that peanuts are not nuts. She's right of course-but only in a strict botanical sense. In everyday English, "nuts" can mean several different things, _and it includes peanuts!_ If you're allergic to peanuts, and someone asks "Are you allergic to nuts?" I strongly advise that you speak up. Don't stay silent-that would be nuts!
@@nHans Just because you haven't taken the time to contemplate and understand why botanists classify something like the strawberry as a non-fruit doesn't invalidate the classification making it or the botanists worthy of ridicule. But, for someone who understands the reason it can be quite helpful even if they are an average consumer. Again, using strawberries as an example, the reason they aren't classified as a fruit is because the strawberry is actually the stem of the plant. This explains why strawberries don't ripen after they are picked, just like how rhubarb doesn't "ripen" once you pick it, because even the average consumer can understand through everyday experience how the stem of a plant and ripening just don't go together. Now armed with this understanding, it is easy to see why strawberries should only be picked when fully ready because a "green" strawberry won't "ripen" any further once picked. Or, if buying strawberries, they should be either refrigerated or immediately consumed because trying to ripen them like a true fruit will only result in moldy strawberries.
You should see what the lawyers did.
That's why it's actually nice to learn physics in a foreign language. I have English as my second language, and the textbook goes "in common speech impulse means..." and I go - "don't need to know that - just tell me what it means in physics".
I'm channeling my inner Kylo Ren here: MOOOOREE!!!
Yes please!
My God! I love when you two collaborate. She has got patience and intelligence to process what you explain! And it feels like she's representing the audience when asking simple but important questions. Please do more!
plz upload rest part also ! i was very keenly listening to it . i guess she is a biologist and thats why she was able to get it very clearly
I think this is a nice addition to your normal approach--and your lovely wife is excellent as a stand-in for us interested but untrained physics fans. Cheers.
I love this channel, I really do. This kind of informal conversation is quite interesting. His wife made quite good questions and pose very intriguing analogies.
Holy cow, please do more videos like this for the really tough topics like quantum mechanics. This was way too short and ended too soon!
I love your normal video style, but this "interview/discussion" style should definitely be in the rotation!
5:57 is the answer to Shrodinger's Cat. The cat isn't alive and dead at the same time, because the cat carries out the observation, or rather the mechanism that releases the particle indicating the radioactive decay.
That superposition thing you described, about particle not being in multiple states simultaneously, was new to me. And it actually gave real sense to this absurd phenomenon!
Thanks for that👍
In Quantum Mechanics, Superposition is one quantum state which is the sum of many quantum states, encompassing "many" classical states. Superposition is a probability distribution (wave function). When measurement takes place, the wave function "collapses" and "actualizes".
"(Quantum) particles exist in a way which violates our intuition" - the best explanation for QM I have ever heard. LOL
We should totally pass a law forbidding quantum mechanics from violating our poor intuition
And that's how QM was worked out by mathematicians. They don't follow intuition, just follow the math wherever it takes them.
Here's a simpler one: Quantum particles don't exist. The wavefunction is a literal description of matter, and it just exists. No need for mystical gobbledygook about things being in more than one place at once or collapsing instantaneously. Just a bunch of waves with quantized interactions.
You should watch Feynman’s Messenger Lectures. He explains these things in the same “regular person” manner, but with more depth. And he mentions intuition :)
4:51 Super good question there, that actually finally made super position properly click in my brain
This is probably one of my fav videos of your stuff. You two should make a separate channel where you two just talk about stuff. Good stuff.
This was awesome, I often struggle talking with people, who are not so in to Physics, about non classical physics as it's so unintuitive. In think this video gives a great mutual understanding and I would love to see the continuation about the interpretations.
She's very cool. You seem to have found someone worthy of yourself. I approve.
Kudos to Future!Nick for giving credit where credit is due. I concur that the tree falling in the woods analogy is a worthwhile way to discuss measurement. Certainly so as a starting point you can expand from.
About explaining super position, how about this:
1. Draw a cube with solid lines on a piece of paper with an arrow on the top facing away from you.
2. Try to see the cube looking from the top and the bottom, the direction of the arrow will change.
Is it appropriate to say that both cubes are in a super position when looking at the drawing in 2D? Also the cubes seem to be entangled because if you know the direction of the arrow in one, the other one is defined instantly and opposite.
Funny how the cubes only emerge when you look at them and until you look, spin up or spin down has no meaning.
Show the whole thing! I really like your wife's questions. She probably clears things up for us non-physicists better than most physicists do,
They seem to have forgotten ocams razor, most basic thing is usually what happens. Yet he uses colloquial terms only those who studied would understand. So us layman just hear a bunch of gibberish, as if its coming from some insane wingnut
As a physics nerd, this is couple goals 😭✨
Yes, please upload
Asf
In 5 years I’ve never heard a more understandable explanation of quantum mechanics. Thank you and More please!!
Wow this was posted yesterday! I really love the style, this is the best video I can find explaining quantum simply. I would REALLY like more of these kinds of videos, and I would REALLY REALLY like a conversation specifically on the EPR paradox. Much love. Also I like the electron's path through a magnetic field from A to B
Hey, I'm hanging off a cliff because a meanie scientist just left me here, HEEELP 😭
First time?
OMG you guys are adorable. Really... And she described everything I think when it comes to physics use of words. A word that doesn't mean exactly that..
A great video Nick. Your lovely wife, very beautiful btw, asked the right questions allowing you to elucidate further. She asked what “others” would ask in an intelligent way. I think you stumbled into a great video formula combining the two video hosts.
I could have watched another hour of this interaction Nick. You’re on to something good. Your wife adds a lot of value to your production. I also noticed you’re not as goofy in front of her. She rules!
I can't help but ship you both so much!
Please upload the whole conversation! And thanks for sharing!
I'd love to see the whole thing.
Me too!
I do as well!
I would love to hear you guys talk about photosynthesis. Her biological understanding and your quantum physics will do the magic. And of course you have to upload the 45 minute video for interpretation of quantum mechanics. 👍
Yup, I really liked this format. Its great for learning. Your Wife was asking great practical questions I wish I could ask.. Your regular format is of course very entertaining and likely more popular. I hope you keep both formats... I'm heading now to hear the rest of the convo.. Thanks!
Glad you enjoyed it!
Please upload the longer version of this conversation. That would be great! Love your work.
Love this format! She and you together are a joy to watch. 🙂
That was amazingly insightful. Cheers!
Awesome video. I'm usually not a real fan of long videos, but this one I was actually disapointed it was done so soon. I was really enjoying the conversation. This has been the best explanation I've seen about quantum physics. You must upload the rest. Haha. Thanks for this video.
Surely you must upload the next part,this style of video is very very relatable to me.....
I’ve just taken a class on this, I’m totally interested in hearing more
I love this style of explanation, giving a direct voice to at least some of the questions had in the audience. Lecture is great but it can often gloss over things that the speaker considers given, even though the audience doesn't know it.
Yeah, there are occasionally pinned comments under my videos answering questions I simply didn't anticipate but should have been addressed in the video.
You should upload rest of the conversation on your Nick Lucid channel.
You have left that channel untouched for a while.
I really liked the format. Personally, I like how you point out common misconceptions (both of you), because it really helps to make sense of the topic. Hope to see more videos like this one!
He found himself a wife? He must have used “spooky action from a distance.”
I needed that laugh!
and it's super effective!
Sexy action at a distance. ;)
Jealous? We nerds have wives and they are really so cool.
This was interesting discussion. A person with some background can offer questions and comments that are not typically repeated by established physicists, thus providing interesting perspective.
This explained a lot to me , I have never seen a quantum mechanics person to person explanation before , the way this video is made makes a spontaneous flow of information to my head,, especially that she asks basic question due to her being new to the field , i hope you make a complete series like this , I like her hair color too.
I love this video for a multitude of reasons:
-Sometimes an outside perspective can really make you question your beliefs and understanding.
-Teaching something to someone can really solidify the idea in your mind.
-It challenges your assumptions of what people know and believe even with overwhelming evidence, mainly because they don’t live and breathe these topics like you might.
You don't need to ask, we all want whole 45 minutes of both of you.
And this is how the Asylum Podcast was born where crazies come to talk about science. AND. I. LOVE. IT.
Please more!
I loved this, and loved you owning up to the tree falling comparison. Great video!
That was an amazing format sir!!!! Would love to see more ❤️❤️🔥🔥
Haha, "you know I've been with you for a while" 0:37
Yesss, gimme full conversation. I need help explaining this stuff to friends and family.
I would love to hear the rest! It was super interesting to watch this conversation and see the conflicting ways two people of different scientific fields view the same situation.
I rarely comment on YT and I'm pretty sure this is the first time I commented on this channel, but I really like this format. It feels like I remember more of what I watched compared to your other videos because I don't question your explanations enough while watching and the only one who asks critical questions is your clone, who doesn't seem to have the same conceptual understanding problems us non-physicists would have.
Which is why credit goes to your wife for her smart questions/input.
TLDR;
love the format, moar plz
Yes. More of the wife. She’s smart and engaging. I would watch a 45 minute discussion
I want that thing you said I should comment about.
I'm looking forward to see the entire conversation!! Your wife is smart and pose really good questions and you are very good at answering 🙂 what a great couple!
Would love to watch the full conversation! Always great work Nick. I'm up for some longer, more loosely structured videos in general.
Yes, I would love to see the rest of the chat on interpretations.
I love the concept of this video. I hope other educational channels like Veritasium, PBS SpaceTime, Isaac Arthur, and Smarter Every Day are inspired to do a similar video. Bring on the S.O.'s, parents, and kids. Our favorite explainers, explaining to a small audience of people they know.
Really like this style of video, the back and forth between you both is excellent
This is fantastic 👏 👌, after all these years I just understood the wave function collapse out of this conversation. Hats off
I want the 45-minute video so bad
Hello. Yes, more. Much more. For the physics and for the adorable husband wife interaction.
Great format. I loved this!
Nick this conversation is really interesting. I would love to see rest of it! Have a great day!
Also just want to say you two are so cute. And she seems really brilliant and picked up on the concepts well. Also you explained it really well
Complete opposite of my physics degree experience. Sloppily explained by professors and it took me a long time to understand. In fact I’m pretty sure I mostly learned about QM concepts AFTER I graduated
Another great idea and follow through on video! What a great way to try to explain Quantum to everyone! Can't wait to see the next video!
Very good video , would've watched even an hour and a half of this conversation. Your wife is a good conversation companion, she asks good questions and helps sharpen the ideas you're trying to convey. I was so in to the conversation It didn't feel like ten minutes had passed and so I was sad when you abruptly announced it is over . Please upload more stuff like this :-)❤
I think we need a poll so you can understand the different levels at which your audience understands you. Like “rate your understanding from 0 to 10” kind of thing.
This "format" has made me see Quantum Mechanics from a new perspective. Good questions!!!
Please upload the full conversation, I would love to hear the rest!
1. You should be quoted on some stuff there' it's good.
2. I would ABSOLUTELY watch 45+ minutes of such stuff.
3. bonus points for the cuteness of both of u.
I relay liked this video style. It feels more dynamic and I just like talks with smart people..
this video needed to be longer. I literally would've been listening for at least 20 more minutes.
I totally agree. I actually came in expecting it and was sad when it was over so quickly
Yes, please post the entire version
definitely upload the rest of this conversation - totally fascinating!
