There is a widespread misunderstanding about the search for quantum gravity in general. We know that quantum gravity works up to the Planck scale, which is ridiculously small. In other words, we know that our current models should work for all experiments we can make today, and further, at least for a very long time. We even know how to calculate the first quantum corrections to gravity (see the beginning of the video). This implies, therefore, that all attempts at formulating a fundamental theory for quantum gravity (not just M theory / string theory, but really ALL attempts) MUST be fundamentally untestable, at least for now and probably for a very long time. This is not a problem of the theories. As of today the goal has never really been to make new predictions that are testable, because we know this is impossible until far out in the future. It might even be fundamentally impossible (some researchers think it's fundamentally impossible to observe gravitons for example). So the goal is really just to try to find a mathematical framework within which we could calculate the higher quantum corrections to gravity. Many people actually think that most attempts will actually turn out to be equivalent. It is thought for instance that many theories can be formulated in terms of a string theory. In other words, string theory might be a universal language to write theories.
I understand that string theory is interesting, but I don't understand why it is mixed with physics topics. I mean, the whole idea of physics is to be able to do experiments to verify hypotheses.
@@canna-kun that's why it's theoretical physics, which is the first place in the scientific method from an observation of gravity waves, to begin the quest to develop experiments to test the quantization of a gravity wave.

What's unbelievable is that a theory such as string/M theory that cannot ever be tested still gets funding and media space after decades of not producing any verifiable predictions. String/M theory is a failed proposition. Time for theoretical physics to move on.
The relative intuition is there to make the mathematics easier to understand, but it doesn't have to be intuitive at all, it's just we use that for conveance on information. It's rather far more complex and hard to understand especially when you get down to the actual numbers.
I am always amazed that this kind of stuff is even possible to figure out, yet another amazing piece by ScienceClic, you are probably the best physics channel currently present on UA-cam.
Thank you for this presentation. Physics at times is so sophisticated (I did Physics at Uni). I believe that when the 'truth' is realised, it will be so simple and easy to understand.
Guys I am really amazed. This and all the other videos are phenomenal and very well done. You guys are one of the best scientific channels on UA-cam. Keep it up!!!
Great as always! I'd like more detail on the last point: people often mention this problem where there are too many possible geometries of the universe to figure out which one ours would be, and I've always wondered what they mean by that. Thanks!
That's a great question about geometries! A good resource for more information would be topology videos, since that's what it's coming from. I'm not certain how good I can describe the intricate parts, but the heart is that we have surprisingly simple methods to find the geometric shape of the universe... But they require calculating angles on a scale of about 1/4 of, not the visible universe, but the *universe* entirely. I don't know if we can even calculate on the scale of the visible universe, but as far as we know the visible universe might only be, say, .0000000001% of the total universe, meaning even if we could calculate, it wouldn't necessarily even be useful. At large scales, everything looks flat, kind of like how the earth looks flat... Until you look at it from the correct angle, and you realize it's a giant sphere. That's what it's like for the universe, but the only perfect angle to view from... Is outside of the universe, which means instead we need math. Lots and lots of math.
@@jem5636 Thank you. I actually had in mind the issue where there are trillions of potential ways the geometry of strings could be configured in 10 dimensions to give us our universe, and we don't know which one belongs to ours.
@@TristanCleveland Ah, I don't know as much about that. I guess I'm also curious to know how people might attempt to test the string geometries. I'm guessing it might also be a problem of angles, though too small to test instead of too big to test.
oook this is the first time from this channel that a concept of a video flew right above my head so quickly, but its understandable! it is the M-theory. i struggle to wrap my head around special relativity, this is far too complex.
@@choieunmi9303 i have watched every single one of his videos. this one just completely blew over my head, im sorry my puny head needs a lot more context, mathematical knowledge and time to even comprehend what is being stated here.
Always look forward to ScienceClic videos!!! I was literally listening to an interview with Prof Brian Greene where he talked about Witton's M theory and the 11 dimensions of space!
I have been under the impression for a long time that the two heterotic, the two Type II and Type I descriptions were 'String Theories', (really just hypotheses), and all work in 10 dimensions rather than the earlier 26-D Bosonic String 'Theory' discarded in favour of QCD, whereas M-Theory, (yet another hypothesis rather than a theory), unified the five 'String Theories' with the dualities and the addition of another dimension, making THIS the 'Superstring Theory'. It looks like I've been living a lie for the past thirty years... Excellent video, BTW - thanks.
The canon is that string theories are appxomiation of what is called M-theory like Feynmans perturbation theory is an approximation to the full nonperturbative QFT. We do not have any idea how to formulate either and it might very well be the case that both M-theory and nonpert. Yang-Mills are the same.
Beautifully animated and after going through many other science programs on the Internet including UA-cam, so far this is the best one to teach my high-school-kids and myself as well the most recent physics on quantum level. I use your pages in my English class at our tiny private school in Sapporo, Japan. Thank you very much.
Every time i get glued to seat until it finishes. In fact I wish the video keep on and on, pouring fundamental knowledge with beautiful visual description.
Dude, wtf one of if not the best youtube channel for physics imho.

This... Ladies and Gentlemen... Is why UA-cam is the ONLY so called social media platform that I am prepared to tolerate! Channels like these feeds my very hungry brain! And you can still get to enjoy the odd cat video too! So yeah... Keep your TikTok, Instagram, Twatter... Or whatever the Hell it's called these days! Just leave UA-cam alone as is! 😁
It amazes me how some people are able to think in such an abstract ways. It's already tremendously difficult to understand the general idea of this, let alone understanding the math. And to actually go and research this stuff and create these models and show the connections between them... I cannot even comprehend that. But nobody lays out the big picture like ScienceClic does it! You can talk about "dualities", 11-th dimensions etc ... but the way it's described here it really makes sense. It gives you a general idea what is going on in this field of research. I'm really excited to see how it will evolve and if people will be able to link it back to the physical world and verify it through experiments and observations.
Hey thanks for making a video on string theory research! Our field (I am a PhD researcher in string theory/ mathematical physics) has become very invisible to the pop science physics channels and mainstream media the last few years and most people have no idea how fascinating is the theatrical physics research field 😊
What you guys do is beyond my mind, and the way you end up to those conclusions is pure magic to me. But I'm happy and thrilled that some one has the patience and passion to do it, as myself don't even begin to understand where and how we can apply this knowledge to our everyday lives.
"theatrical physics" freudian slip there, eh. If you wonder why string theory doesn't get attention anymore maybe look to the indeed very 'theatrical' grifters selling wild, unprovable physics to the public
Fantastic video, like always! But while I admit to only having an extreme surface level knowledge of String / M theory (so my opinion is probably worth very little!), it's development has always appeared to me as an increasingly desperate attempt to just try and make something fit, to make *anything* fit. To grab gravity and QM, glue them together in any way possible and hope they stay stuck together long enough to resemble a unified theory. But more than that, while String theory is definitely abstract, it just doesn't seem "absurd" enough (to use Feynman's language) - in such a way that it seems to betray the spirit of quantum theory. When I first discovered quantum theory my mind was blown by how utterly ridiculous nature really is, and how incredible some of its implications were. In contrast, while it is certainly interesting, the more I learn about String / M theory, the more secretly hopeful I become that it's shown to be wrong, because I just have a nagging skepticism saying surely underneath everything can't be something so... sensible. Remember the briefcase from Pulp Fiction that we never got to see the glowing contents of? Imagine if you finally got to see inside and it was just an orange light bulb. Wouldn't you be a bit disappointed that it turned out to be so boring and regular and predictable? It's the only metaphor I can think of.
I agree with alot of what you said, and am in a somewhat similar position. Though I am not really against the idea nor am I frightened that it might turn out to be underwhelming. The universe is absolutely amazing, and ancient cultures had lots of interesting ideas/teachings that align surprisingly well with some of these discoveries. I just hope they dont get too wrapped up in the particulars of something they cant fully digest, before allowing for a wider brainstorm with perspectives from other fields. Communication is what makes our species so wonderful at discovering and exploring new ideas, so I would think it reasonable to suggest a more open discussion and taking inspiration from other perspectives and lenses. What I mean by that specifically, is like how a psychologist understands the world in a particular way, viewing it through the focus of the mental and biological world of the human brain. Biology as a whole is much the same way, all these fields are reaching fontiers of knowledge and understanding...and aren't interacting enough to help solve eachother's gaps. I'm a big fan of esotericism because it encourages that very concept. Sometimes the ideas or connections turn out to be completely misunderstood, but so much more often do I see concepts meld together in ways I never even would have imagined otherwise. The world, especially the western scientific world, has an issue with rigidity, not allowing the fluid nature of the creative mind and intuitive curiosity to encourage a diversity of ideas which are accepted as possibilities. Deep down, to be honest, I find a great deal of stimulation and comfort from the ideas of the hermetics, Qaballists, Tantrik teachings, sacred geometry (wildly connected to these topics at least conceptually), etc. Not that everything is true in these viewpoints, but they often offer fascinating frameworks through which a person could view themselves, the world, and many of these fundamental laws or dimensional planes. All while encouraging a focus on introspection, afterall we ought to stay sane otherwise we can't get much done, at least in a sustainable way.
The legendary Edward Witten. His high school classmates used to say when he left the room “there goes the smartest person in the world”. And they were right
Just wanna say, I don’t understand a thing of physics, nor do I completely understand what is happening on the screen, but I like funny words and pretty pictures. The fact that I still get at least the general idea of what is being explained is fascinating to me tbh xD
I wonder why you used the "stereotypical" picture of general relativity @1:00 instead of the (more accurate) one you pioneered in one of your earliest videos.
At this point, M and String Theory are mostly for mathematical investigation. They have never generated a single, unique testable prediction. Supersymmetry *has* been tested, and all remotely reasonable versions have been excluded by experiment.
Wow the visualisation is soo amazing...I'm just a phyiscs enthusiast with no back ground in phyiscs or maths and yet i got soo much ❤❤..New subscriber!❤
The problem with most string theories is that they explain phenomena but make very few predictions (often none, or very trivial predictions). This makes them difficult to verify or disprove. The promise of a theory of everything, after centuries of edging, is still just a promise
"Newtons constant may have in fact been infinity" Hearing this blows my mind because I've recently been toying with this idea myself as a prospect that could potentially lead to some unified theory / new understanding of physics
m theory has always made sense to me more than most of the “theories of everything” i believe that people only disregard it so much due to how close to impossible it is to prove, but maybe some things in science are not supposed to be known or even fathomed by our human minds, like how a time before time cant be imagined a 1d or 26d string is just inconceivable to our 3d idea of reality, it does not mean its not how it works just that we cant explain or comprehend it ourselves.
people go on and on about 'imaginary dimensions' but how do they think matter came into being in this universe? Another 'dimension', 'plane' ... brane that came into contact with this one. Then they get all flustered and indignant, demanding that the origin of those be explained, something that even if proven would take possible millenia to explain. There is no winning with these people.
This was such a good video bro, the production was insane and you deserve so many more views and subscribers. I loved how your explanations were simple enough without disregarding too much information and you taught me so much stuff like I had no idea Hawking radiation from blackholes matched up with strings , thats so crazy, definitely convincing for string theory, this video so accurately compiled the history and is desperately needed especially now when the public is saying that string theory is dead, or I guess M theory now.
There is a widespread misunderstanding about the search for quantum gravity in general. We know that quantum gravity works up to the Planck scale, which is ridiculously small. In other words, we know that our current models should work for all experiments we can make today, and further, at least for a very long time.

Thank you for this presentation. Physics at times is so sophisticated (I did Physics at Uni). I believe that when the 'truth' is realised, it will be so simple and easy to understand.
Oh my god. First the GTA VI trailer and now this. I'll enjoy anything that challenges my sense of time and space.
Guys I am really amazed. This and all the other videos are phenomenal and very well done. You guys are one of the best scientific channels on UA-cam. Keep it up!!!
Great as always! I'd like more detail on the last point: people often mention this problem where there are too many possible geometries of the universe to figure out which one ours would be, and I've always wondered what they mean by that. Thanks!
That's a great question about geometries! A good resource for more information would be topology videos, since that's what it's coming from.
I'm not certain how good I can describe the intricate parts, but the heart is that we have surprisingly simple methods to find the geometric shape of the universe... But they require calculating angles on a scale of about 1/4 of, not the visible universe, but the *universe* entirely. I don't know if we can even calculate on the scale of the visible universe, but as far as we know the visible universe might only be, say, .0000000001% of the total universe, meaning even if we could calculate, it wouldn't necessarily even be useful.
At large scales, everything looks flat, kind of like how the earth looks flat... Until you look at it from the correct angle, and you realize it's a giant sphere. That's what it's like for the universe, but the only perfect angle to view from... Is outside of the universe, which means instead we need math. Lots and lots of math.
@@jem5636 Thank you. I actually had in mind the issue where there are trillions of potential ways the geometry of strings could be configured in 10 dimensions to give us our universe, and we don't know which one belongs to ours.
@@TristanCleveland Ah, I don't know as much about that. I guess I'm also curious to know how people might attempt to test the string geometries. I'm guessing it might also be a problem of angles, though too small to test instead of too big to test.
Yesterday night in french, tonight in english. You are the GOAT of science videos imo.
oook this is the first time from this channel that a concept of a video flew right above my head so quickly, but its understandable! it is the M-theory. i struggle to wrap my head around special relativity, this is far too complex.
Check out the original string theory video, it might help with understanding. Also it's one of the greatest on the channel in my opinion.
@@choieunmi9303 i have watched every single one of his videos. this one just completely blew over my head, im sorry my puny head needs a lot more context, mathematical knowledge and time to even comprehend what is being stated here.
Always look forward to ScienceClic videos!!! I was literally listening to an interview with Prof Brian Greene where he talked about Witton's M theory and the 11 dimensions of space!
i‘m not educated enough to understand any of that…
10/10 would watch again!
one of the greatest channel on youtube. Please never stop !
I have been under the impression for a long time that the two heterotic, the two Type II and Type I descriptions were 'String Theories', (really just hypotheses), and all work in 10 dimensions rather than the earlier 26-D Bosonic String 'Theory' discarded in favour of QCD, whereas M-Theory, (yet another hypothesis rather than a theory), unified the five 'String Theories' with the dualities and the addition of another dimension, making THIS the 'Superstring Theory'. It looks like I've been living a lie for the past thirty years...
Excellent video, BTW - thanks.
The canon is that string theories are appxomiation of what is called M-theory like Feynmans perturbation theory is an approximation to the full nonperturbative QFT. We do not have any idea how to formulate either and it might very well be the case that both M-theory and nonpert. Yang-Mills are the same.
Je commente pour le référencement.
Scienclic english doit devenir numero 1 en vulgarisation scientifique
I enjoy your works immensely! I am now in my third year of Physics and CS degree, started watching you pre-academia
I hardly understood anything, but the production of this video is off the charts!
This is the most comprehensive explanation of M-theory I have seen so far.
Watching this in the bathroom, we gettin enlightened with this one 🔥
When the world needed him the most, he came back with an absolute banger
Great video Ive been looking forward to your video on M Theory and was not disappointed. I learned several new concepts.
Another great lecture that takes a subject that's light years over my head and making it possible to comprehend.
Beautifully animated and after going through many other science programs on the Internet including UA-cam, so far this is the best one to teach my high-school-kids and myself as well the most recent physics on quantum level. I use your pages in my English class at our tiny private school in Sapporo, Japan. Thank you very much.
Thanks for this amazing video. M is the mirror image of W. Maybe because Witten, Edward. What a genious.
this is fascinating. I hope we get more videos on the other candidate theories
Every time i get glued to seat until it finishes. In fact I wish the video keep on and on, pouring fundamental knowledge with beautiful visual description.
You madlad, you did it! You covered M Theory! This was a good explainer. Keep up the AMAZING work!
Dude,
wtf one of if not the best youtube channel for physics imho. Alessandro is the explanation god. the topics are so well structured and explained on a level for non-physicist easy to understand. rly nice animations as well. btw very good narrating. all in all great job bro's, pls keep up and sry for possible bullshit writing i am drunk and st0ned haha😅 (no worries, both legal here)
Love this channel ❤
Make more videos like this!
I don't get it why aren't there more creators like ScienceClic??? Thanks Alessandro and team!!! Your are a whole other level when compared to all the other physics creators.
There are other good ones. Maybe not quite up to the graphical prowess of Alessandro, but the content is just as good:
eugene khutoryansky - ua-cam.com/channels/J0yBou72Lz9fqeMXh9mkog.html
PBS spacetime - sometimes more ... well, funny, butyalways solid: ua-cam.com/channels/7_gcs09iThXybpVgjHZ_7g.html
german, boring, but very good: ua-cam.com/play/PLmDf0YliVUvGGAE-3CbIEoJM3DJHAaRzj.html
But I love his videos, too :-) A lot.
@@eurotrash5610 Thank you!!
I love seeing this channel grow. This helped me a lot in understanding Gravity, General Relativity, Frames of reference, etc.
Succinct and elegant, eerie yet dry. I don't understand a thing. I love it!
Thanks for another great video!
It's a very special and rare moment, whenever I get new upload notification from you
so so true
No way I’ve been waiting for this forever
the best science channel of my life
So does this mean that in M Theory particles and dimensions are the same thing?
OH MY GOD MY FAVOURITE UA-camR
This... Ladies and Gentlemen... Is why UA-cam is the ONLY so called social media platform that I am prepared to tolerate!
Channels like these feeds my very hungry brain! And you can still get to enjoy the odd cat video too!
So yeah... Keep your TikTok, Instagram, Twatter... Or whatever the Hell it's called these days!
Just leave UA-cam alone as is! 😁
It amazes me how some people are able to think in such an abstract ways. It's already tremendously difficult to understand the general idea of this, let alone understanding the math. And to actually go and research this stuff and create these models and show the connections between them... I cannot even comprehend that.
But nobody lays out the big picture like ScienceClic does it! You can talk about "dualities", 11-th dimensions etc ... but the way it's described here it really makes sense. It gives you a general idea what is going on in this field of research.
I'm really excited to see how it will evolve and if people will be able to link it back to the physical world and verify it through experiments and observations.
Hey thanks for making a video on string theory research! Our field (I am a PhD researcher in string theory/ mathematical physics) has become very invisible to the pop science physics channels and mainstream media the last few years and most people have no idea how fascinating is the theatrical physics research field 😊
What you guys do is beyond my mind, and the way you end up to those conclusions is pure magic to me. But I'm happy and thrilled that some one has the patience and passion to do it, as myself don't even begin to understand where and how we can apply this knowledge to our everyday lives.
What’s current research in string theory going into?
We'll get you those extra dimensions. Don't you worry. Experimental physics is on the way.
find a new field!
"theatrical physics" freudian slip there, eh. If you wonder why string theory doesn't get attention anymore maybe look to the indeed very 'theatrical' grifters selling wild, unprovable physics to the public
A very nice description of dualities.
Does this channel have a Patreon?
This stuff just gets so wild, when you step back and think about it, we really still have alot to learn.
Fantastic video, like always!
But while I admit to only having an extreme surface level knowledge of String / M theory (so my opinion is probably worth very little!), it's development has always appeared to me as an increasingly desperate attempt to just try and make something fit, to make *anything* fit. To grab gravity and QM, glue them together in any way possible and hope they stay stuck together long enough to resemble a unified theory.
But more than that, while String theory is definitely abstract, it just doesn't seem "absurd" enough (to use Feynman's language) - in such a way that it seems to betray the spirit of quantum theory.
When I first discovered quantum theory my mind was blown by how utterly ridiculous nature really is, and how incredible some of its implications were. In contrast, while it is certainly interesting, the more I learn about String / M theory, the more secretly hopeful I become that it's shown to be wrong, because I just have a nagging skepticism saying surely underneath everything can't be something so... sensible.
Remember the briefcase from Pulp Fiction that we never got to see the glowing contents of? Imagine if you finally got to see inside and it was just an orange light bulb. Wouldn't you be a bit disappointed that it turned out to be so boring and regular and predictable? It's the only metaphor I can think of.
I agree with alot of what you said, and am in a somewhat similar position. Though I am not really against the idea nor am I frightened that it might turn out to be underwhelming. The universe is absolutely amazing, and ancient cultures had lots of interesting ideas/teachings that align surprisingly well with some of these discoveries. I just hope they dont get too wrapped up in the particulars of something they cant fully digest, before allowing for a wider brainstorm with perspectives from other fields.
Communication is what makes our species so wonderful at discovering and exploring new ideas, so I would think it reasonable to suggest a more open discussion and taking inspiration from other perspectives and lenses. What I mean by that specifically, is like how a psychologist understands the world in a particular way, viewing it through the focus of the mental and biological world of the human brain. Biology as a whole is much the same way, all these fields are reaching fontiers of knowledge and understanding...and aren't interacting enough to help solve eachother's gaps. I'm a big fan of esotericism because it encourages that very concept. Sometimes the ideas or connections turn out to be completely misunderstood, but so much more often do I see concepts meld together in ways I never even would have imagined otherwise.
The world, especially the western scientific world, has an issue with rigidity, not allowing the fluid nature of the creative mind and intuitive curiosity to encourage a diversity of ideas which are accepted as possibilities. Deep down, to be honest, I find a great deal of stimulation and comfort from the ideas of the hermetics, Qaballists, Tantrik teachings, sacred geometry (wildly connected to these topics at least conceptually), etc. Not that everything is true in these viewpoints, but they often offer fascinating frameworks through which a person could view themselves, the world, and many of these fundamental laws or dimensional planes. All while encouraging a focus on introspection, afterall we ought to stay sane otherwise we can't get much done, at least in a sustainable way.
Please do a video on BCS theory of superconductivity. Thank you!
>string thoery
it's so over
Omfg the professor’s voice and enunciation😮
Dude was def the inspiration for Revenge of the Nerds
The legendary Edward Witten. His high school classmates used to say when he left the room “there goes the smartest person in the world”. And they were right
Just wanna say, I don’t understand a thing of physics, nor do I completely understand what is happening on the screen, but I like funny words and pretty pictures. The fact that I still get at least the general idea of what is being explained is fascinating to me tbh xD
I wonder why you used the "stereotypical" picture of general relativity @1:00 instead of the (more accurate) one you pioneered in one of your earliest videos.
This was one of the best scientific videos I've watched for a long time! Amazing work!
At this point, M and String Theory are mostly for mathematical investigation. They have never generated a single, unique testable prediction. Supersymmetry *has* been tested, and all remotely reasonable versions have been excluded by experiment.
By far the best explaination on M theory so far on the internet
First
Great work. I am a surgeon and I love physics ,can you suggest books or videos to have a good physical knowledge
🫡
Wow the visualisation is soo amazing...I'm just a phyiscs enthusiast with no back ground in phyiscs or maths and yet i got soo much ❤❤..New subscriber!❤
The problem with most string theories is that they explain phenomena but make very few predictions (often none, or very trivial predictions). This makes them difficult to verify or disprove. The promise of a theory of everything, after centuries of edging, is still just a promise
edging is not a word id thought id see used when discussing quantum mechanics
Thank you for the time you put in this video
Excellent presentation.
Watching this video might have been on of the only times I’ve had to pause a video to grasp what has just been said
Every video you put out is fascinating, and easy to follow. You should be proud! :D
I'VE BEEN WAITING FOR THIS VIDEO SINCE I DISCOVERED YOUR CHANNEL LIKE 2-3 YEARS AGO
Thats the absolute madness man i want to learn more about it.
Keep making videos like this
I had been waiting for this. Fantastic video as always man!
"Newtons constant may have in fact been infinity"
Hearing this blows my mind because I've recently been toying with this idea myself as a prospect that could potentially lead to some unified theory / new understanding of physics
If your universe idea has an infinite gravitational constant it is a nice universe model but not the model of this universe
Great video on a complex and incredibly abstract subject!
best yt channel is back!
m theory has always made sense to me more than most of the “theories of everything” i believe that people only disregard it so much due to how close to impossible it is to prove, but maybe some things in science are not supposed to be known or even fathomed by our human minds, like how a time before time cant be imagined a 1d or 26d string is just inconceivable to our 3d idea of reality, it does not mean its not how it works just that we cant explain or comprehend it ourselves.
people go on and on about 'imaginary dimensions' but how do they think matter came into being in this universe? Another 'dimension', 'plane' ... brane that came into contact with this one. Then they get all flustered and indignant, demanding that the origin of those be explained, something that even if proven would take possible millenia to explain. There is no winning with these people.
This video (in addition to its fabulous content and explanations) looked stunning! Very well done!
This was such a good video bro, the production was insane and you deserve so many more views and subscribers. I loved how your explanations were simple enough without disregarding too much information and you taught me so much stuff like I had no idea Hawking radiation from blackholes matched up with strings , thats so crazy, definitely convincing for string theory, this video so accurately compiled the history and is desperately needed especially now when the public is saying that string theory is dead, or I guess M theory now.
thank you for the hardwork
Love the cool music
Loving the channel, keep up the high quality work.
He's back! I'd given up hope. This'll have to hold us over the winter.
