Any hadron, really, but most are so unstable that they stop being hadrons before any attempt could be made to tear them apart. After nucleons, the most stable hadrons are two-quark mesons, which have half-lives measured in fractions of a second (iirc, the half life of neutral pions is something like 5ns). They're still a good example of the concept, though, since it's easier to explain how the binding energy being greater than the rest-mass-energy of the composite particle will result in copying the particle if an attempt is made to tear it apart when 1. There's only two elementary particles in the composite (simpler system) and 2. There's already an equal number of particles and anti-particles in the system.

I made my PhD at the GSI lab in Germany. Along the hall of the linear accelerator they had all those chemistry labs. Which where used as store rooms in the 90s. When the lab was founded back in the 70s there were predictions about this island of stability that let them believe they could create gramms of this stuff and it would live long enough to do chemistry. Turned out both the predicted cross sections and half lifes were off by a few orders of magnitue. However GSI found many of the z>100 elements over the years, but no chemists ever got their hands on them.

You have a gift that few have, the ability to advocate for reason and rationality, the knack for making it fun, and the opportunity to make an impact. More importantly, you recognized all this and you actually did it. This is literally making a difference, literally changing the world one video at a time.

I think the upper limit to theoretical proton number is supposed to be where the nucleus is too large for a virtual meson to cross the nucleus before decaying, meaning that it's literally impossible (well, really so statistically unlikely that we'll never see it happen, because that's how quantum physics works) for the one side of the nucleus to be bound to the other by the strong force, making the coulomb force shoving protons apart effectively the only force acting on the outer shell. I seem to recall reading that there's a little disagreement about whether that size would be reached before or after the island of stability, because the math to predict the actual shape of a large nucleus gives multiple answers, and there's no consensus on whether the island of stability for proton number will allow the number of neutrons to be reduced enough to shrink the physical size of the nucleus without becoming unstable just from the z/n ratio being off. So I guess we'll just have to do actual experiments to find out.

Like maybe with enough of one of the heaviest elements mixed with something else we could get some really funky emergent properties. Sure we know what the individual atom’s behaviors might be based on measurements, but we don’t have a comprehensive understanding of all the emergent properties of everything. We are still working on that.

I recommend dabbling in some physics for sure. The mathematics is usually the hardest part for people. The interesting part about physics is what the 'physical axioms' are and how different branches of physics relate to each other. The most interesting thing about physics for me is that it's an absolute gold mine when it comes to taking a short list of axioms (in reality, think of them as a physical hypothesis like 'local charge conservation') and creating a fully functioning mathematical model. Seeing how these constructions change from one topic to other is really interesting and enlightening even from an armchair perspective. Some random physics rabbit holes might include understanding what Maxwell's equations are trying to say in plain English, but then how does the mathematics allow you to calculate the speed of light. If the speed of light is the same in all reference frames, what are the consequences for space, time and simultaneity (just follow along basic thought experiments used to calculate time dilation and length contraction)? In the previous situation, they literally use basic triangle math to calculate how space and time are different for different observers, it's wild. Another rabbit hole that's a little more difficult, how can you use conserved quantities like mass and energy to explain a fluid? At the end of the day, the equations of motion for a fluid are basically just conservation laws applied to the idea of a fluid, but all these cool features of fluids pop out of the math as a result. This topic, in my mind, is a masterclass in variable management. There's a very complicated general theory and yet much simpler theories for particular cases. Last and my personal favorite, how can you use the ideas of probability and counting (basic combinatorics) to explain things that thermodynamics takes for granted? Why does time seem reversible in theory but not in practice, and how can you explain, using counting and probability, why entropy increases?

A couple of cool/interesting points you didn't mention in regards to 'big' elements. First, is that one requirement (by the official definition) for a new element is the nucleus must exist long enough to assemble its own electron cloud, which is calculated as some tiny amount of time I've forgotten. So nuclei which are too large and decay faster than this would technically not be a new element, but just a really massive subatomic particle. Also, there is the fine structure constant which leads to potential elements starting to do some truly bizarre stuff around element 137 due to the fact that their innermost electrons would have a highly relativistic kinetic energy.

Based on a Colloquium talk in grad school by a guy at NIST who specializes in Uranium chemistry you already start to get small yet statistically significant deviations from expected properties in the Actinide elements because their outermost valence shells start to become relativistic messing with the chemistry a bit. Of course you kind of need to have the elements supercooled to get the really exotic properties. I also remember learning about just how chemically toxic and reactive Uranium is and how that chemistry makes it way more dangerous than its radioactivity. Uranium as a strong chemical affinity for oxygen in particular which means its quite reactive as a metal with the main reaction product between Uranium and molecular oxygen being water soluble and thus highly motile in the environment. It also apparently has the tendency to behave like it has 4 valence electrons which plays a role in why it has such an affinity for oxygen. Another fun quirk about Uranium and the other sort of stable actinides is that due to their affinity with oxygen even though they are very heavy elements their tendency to bind up with oxygen the 3rd most abundant element in the universe and primary constituent of lighter weight silicate rocks when planets differentiate Uranium and Thorium generally rise to the surface and concentrate in the crust specifically lighter continental rocks. This in combination with the otherwise chemically immobile Uranium being able to react with molecular oxygen to make a water soluble salt was why natural Uranium fission reactors were able to form not long after the Great Oxygenation Event as the ratio of U235 was high enough for Uranium to be fissile and water was able to act as both the concentrator and the moderator in the reaction

I believe this is the first time I've heard of the nuclear shell model. It is aesthetically pleasing to have the nucleus conceptually similar to the electrons around the nucleus (apart from there not being a nucleus in the middle of the nucleus). I know aesthetics are not a rigorous guide for good physics but when it works out that way my brain likes it more. Are we (humans) satisfied, for now, that the nuclear shell model is complete, or are there unsatisfactory aspects that suggest a better model still is needed?

"Magic numbers" are also used by programmers when talking about number literals scattered in your code. They're frowned upon, and generally should be computed or retrieved from somewhere more appropriate, rather than hard-coded in the logic of the program. So I understand the aversion to "magic numbers," because it would make more sense if they could be derived from something else. But it's also not always a bad thing because sometimes numbers just need to stand on their own.

'Plum Pudding' has a couple of meanings here in England... nowadays it is just a baked/steamed cakelike dessert made with plums, but in the olden-days it referred to the steamed sticky treacle (molasses) abomination we call Christmas Pudding (not the lovely booze-infused dried-fruit filled Christmas Cake, btw) and contained all manor of fruits including plums, raisins, citrus peels, dried apple and figs... which lent themselves to it also being called 'Figgy Pudding' thanks to Dickens. This Plum Pudding replaced the less popular 'Plumb Pudding', which aside from being far too heavy for even a team of scullery-maids to remove from the oven, was, of course, deadly....😉.... although it felt the same in one's stomach as the real Plum Pud🤣🤣🤣 (we Brits refer to having dessert as having 'pudding' as we used to eat lot's of sweet, fruit-filled stodge (such as Spotted Dick, Sticky Toffee, Bread and Butter Pudding...) after meals and the name became synonymous with dessert)

Any hadron, really, but most are so unstable that they stop being hadrons before any attempt could be made to tear them apart. After nucleons, the most stable hadrons are two-quark mesons, which have half-lives measured in fractions of a second (iirc, the half life of neutral pions is something like 5ns). They're still a good example of the concept, though, since it's easier to explain how the binding energy being greater than the rest-mass-energy of the composite particle will result in copying the particle if an attempt is made to tear it apart when 1. There's only two elementary particles in the composite (simpler system) and 2. There's already an equal number of particles and anti-particles in the system.

I made my PhD at the GSI lab in Germany. Along the hall of the linear accelerator they had all those chemistry labs. Which where used as store rooms in the 90s. When the lab was founded back in the 70s there were predictions about this island of stability that let them believe they could create gramms of this stuff and it would live long enough to do chemistry. Turned out both the predicted cross sections and half lifes were off by a few orders of magnitue. However GSI found many of the z>100 elements over the years, but no chemists ever got their hands on them.

You have a gift that few have, the ability to advocate for reason and rationality, the knack for making it fun, and the opportunity to make an impact. More importantly, you recognized all this and you actually did it. This is literally making a difference, literally changing the world one video at a time.

The real monsters is the topologist , they like to turn donuts inside out!
I think the upper limit to theoretical proton number is supposed to be where the nucleus is too large for a virtual meson to cross the nucleus before decaying, meaning that it's literally impossible (well, really so statistically unlikely that we'll never see it happen, because that's how quantum physics works) for the one side of the nucleus to be bound to the other by the strong force, making the coulomb force shoving protons apart effectively the only force acting on the outer shell. I seem to recall reading that there's a little disagreement about whether that size would be reached before or after the island of stability, because the math to predict the actual shape of a large nucleus gives multiple answers, and there's no consensus on whether the island of stability for proton number will allow the number of neutrons to be reduced enough to shrink the physical size of the nucleus without becoming unstable just from the z/n ratio being off. So I guess we'll just have to do actual experiments to find out.
I think you've found the weird island of stability for KZread. Like sure your videos aren't polished but they're just so good.

Love your video as usual. My only “gripe” (not actually a real gripe just wanted to comment on the matter, happy accidental pun) with this video is that some of the elements we have not been able to play that much with, I feel… like if we had enough of it we could but they have to be created with a lot of effort and it’s very difficult to accumulate enough of them to truly “play” with them. Like maybe with enough of one of the heaviest elements mixed with something else we could get some really funky emergent properties. Sure we know what the individual atom’s behaviors might be based on measurements, but we don’t have a comprehensive understanding of all the emergent properties of everything. We are still working on that.

This was so good! So many wonderful things, cogently and sometimes hilariously laid out. Thank you.
I really appreciate the level of technical detail in your videos. Accessible, but also new info and more details for someone who has already read a lot about this stuff. This is how one should youtube...thanks!
Thank you for standing up for the most important issue of our time. People who cut up donuts are monsters. Also as a programmer and aspiring mathematician (getting my masters in applied maths now) who doesn't know any of the physics that much of mathematics was developed to explain, I absolutely love your videos.

I recommend dabbling in some physics for sure. The mathematics is usually the hardest part for people. The interesting part about physics is what the 'physical axioms' are and how different branches of physics relate to each other. The most interesting thing about physics for me is that it's an absolute gold mine when it comes to taking a short list of axioms (in reality, think of them as a physical hypothesis like 'local charge conservation') and creating a fully functioning mathematical model. Seeing how these constructions change from one topic to other is really interesting and enlightening even from an armchair perspective. Some random physics rabbit holes might include understanding what Maxwell's equations are trying to say in plain English, but then how does the mathematics allow you to calculate the speed of light. If the speed of light is the same in all reference frames, what are the consequences for space, time and simultaneity (just follow along basic thought experiments used to calculate time dilation and length contraction)? In the previous situation, they literally use basic triangle math to calculate how space and time are different for different observers, it's wild. Another rabbit hole that's a little more difficult, how can you use conserved quantities like mass and energy to explain a fluid? At the end of the day, the equations of motion for a fluid are basically just conservation laws applied to the idea of a fluid, but all these cool features of fluids pop out of the math as a result. This topic, in my mind, is a masterclass in variable management. There's a very complicated general theory and yet much simpler theories for particular cases. Last and my personal favorite, how can you use the ideas of probability and counting (basic combinatorics) to explain things that thermodynamics takes for granted? Why does time seem reversible in theory but not in practice, and how can you explain, using counting and probability, why entropy increases?
“… because E=MC^2.” *pause for outraged spluttering from the audience* “We can use that here.. It’s FINE.” 😂
That was awesome. Love the transition/outro music. Island of stability ftw 🙌
Excellent. This finally answered the question for me of why nuclear fusion in stars ends at iron, leading to someone in the next room asking why I was shouting "Ohhhhh! That's why!"
Letting you know that the Wikipedia article has been updated, and someone tried to link your video as a source, but it was refused (the sourcing, not the edit).
A couple of cool/interesting points you didn't mention in regards to 'big' elements. First, is that one requirement (by the official definition) for a new element is the nucleus must exist long enough to assemble its own electron cloud, which is calculated as some tiny amount of time I've forgotten. So nuclei which are too large and decay faster than this would technically not be a new element, but just a really massive subatomic particle. Also, there is the fine structure constant which leads to potential elements starting to do some truly bizarre stuff around element 137 due to the fact that their innermost electrons would have a highly relativistic kinetic energy.

Based on a Colloquium talk in grad school by a guy at NIST who specializes in Uranium chemistry you already start to get small yet statistically significant deviations from expected properties in the Actinide elements because their outermost valence shells start to become relativistic messing with the chemistry a bit. Of course you kind of need to have the elements supercooled to get the really exotic properties. I also remember learning about just how chemically toxic and reactive Uranium is and how that chemistry makes it way more dangerous than its radioactivity. Uranium as a strong chemical affinity for oxygen in particular which means its quite reactive as a metal with the main reaction product between Uranium and molecular oxygen being water soluble and thus highly motile in the environment. It also apparently has the tendency to behave like it has 4 valence electrons which plays a role in why it has such an affinity for oxygen. Another fun quirk about Uranium and the other sort of stable actinides is that due to their affinity with oxygen even though they are very heavy elements their tendency to bind up with oxygen the 3rd most abundant element in the universe and primary constituent of lighter weight silicate rocks when planets differentiate Uranium and Thorium generally rise to the surface and concentrate in the crust specifically lighter continental rocks. This in combination with the otherwise chemically immobile Uranium being able to react with molecular oxygen to make a water soluble salt was why natural Uranium fission reactors were able to form not long after the Great Oxygenation Event as the ratio of U235 was high enough for Uranium to be fissile and water was able to act as both the concentrator and the moderator in the reaction
I love these! Comments: also, a “plumb bob” is a weight on a string used by carpenters to have a vertical line…originally of lead, yes also used by plumbers for joining pipes….and so we say a wall is “plumb” if it’s straight vertical.

Great video. I learned so much, painlessly!
"Ok. Only the cool people are left." I need to stop you right there.
27:50 I was 4 minutes too late to edit the Wikipedia article; it was already done. Congrats to Qwuk for beating me to the punch. You aren't cited, though. There's no citation for noticing a mistake and removing it lol.

Ah that was me. It's not appropriate to cite a KZread video on the page or in the edit summary unfortunately, at least when the actual explanation is on the Nobel website itself 😅 I was very tempted though
I believe this is the first time I've heard of the nuclear shell model. It is aesthetically pleasing to have the nucleus conceptually similar to the electrons around the nucleus (apart from there not being a nucleus in the middle of the nucleus). I know aesthetics are not a rigorous guide for good physics but when it works out that way my brain likes it more. Are we (humans) satisfied, for now, that the nuclear shell model is complete, or are there unsatisfactory aspects that suggest a better model still is needed?
You are so awesome. This is my favorite channel lately. Thank you very much!
I really love your talks. This one in particular was amazingly informative. I only have undergrad physics from 55 years ago, and this talk has really given me a better understanding of why things are as they are. Many thanks!
As a dense and positive man myself, I feel great affinity for nuclei.
Great video! And you're right, the YTBer "Kathy loves physics and history" has some very interesting videos about German Physicists post WWII
Absolutely love these videos, feels like a physics course for free (with some history thrown in for free)
14:12 "I have not seen the barbie movie yet" while talking about a ww2 german physicist lol
I love your videos. You make the subjects really interesting. This could be a real career opportunity. If you finish your phd, try to find an editor. I am sure you could become as popular as veritasium or other popular science channels.
I want more elements named after countries. Like Chileum, Morroccum, Egyptium, Indonesium, Mexiconium, Naminium, Portugalium…

This is my favourite video of yours yet.
Woke up and saw this posted. So hyped for this afternoon when I have a chance to watch.
"Magic numbers" are also used by programmers when talking about number literals scattered in your code. They're frowned upon, and generally should be computed or retrieved from somewhere more appropriate, rather than hard-coded in the logic of the program. So I understand the aversion to "magic numbers," because it would make more sense if they could be derived from something else. But it's also not always a bad thing because sometimes numbers just need to stand on their own.
Thank you for making learning about science so engaging and fun, somehow I can actually understand and concentrate on things that are said in your videos
You will probably never see this but please make merch. I need a shirt that says “we live in a society” in a semi circle over a half eaten donut.
Reeeeally good video. A lot of science content is streamlined so much so it can be easily understood that it often leaves out key nuances. It’s really nice to have someone go into more detail on complex topics that are usually over simplified. Really interesting stuff too, the PBS space time channel made a similar video in which they seemed more optimistic about an “island of stability” It’d be really cool to hear your thoughts on the possibilities of super-heavy elements and breaking the laws of physics. Thanks for making this.

I don't think any real nuclear physicist thinks that the islands of stability would actually be all that stable, but hype sells. And the media keeps falling for it.
'Plum Pudding' has a couple of meanings here in England... nowadays it is just a baked/steamed cakelike dessert made with plums, but in the olden-days it referred to the steamed sticky treacle (molasses) abomination we call Christmas Pudding (not the lovely booze-infused dried-fruit filled Christmas Cake, btw) and contained all manor of fruits including plums, raisins, citrus peels, dried apple and figs... which lent themselves to it also being called 'Figgy Pudding' thanks to Dickens. This Plum Pudding replaced the less popular 'Plumb Pudding', which aside from being far too heavy for even a team of scullery-maids to remove from the oven, was, of course, deadly....😉.... although it felt the same in one's stomach as the real Plum Pud🤣🤣🤣 (we Brits refer to having dessert as having 'pudding' as we used to eat lot's of sweet, fruit-filled stodge (such as Spotted Dick, Sticky Toffee, Bread and Butter Pudding...) after meals and the name became synonymous with dessert)
Great review and presentation. Highly appreciated. I also liked looking at the book titles in the background.
“No one wants half a donut, we live in a society” should be a shirt
I love these videos! Thank you so much for sharing your insights.
An Anglea Collier and a Summoning Salt video on the same day. What a time to be alive :)
26:55 I have never seen a more "played in the movie by Christopher walken" individual in my life
The sexism in physics videos folder bit got me good
Every time she mentioned the island of stability i couldn't avoid thinking about BobbyBrocolli's video about the fake element discovery
Most under-rated video/image editor
Another funny and educational video. So happy to have found your youtube channel.
Bring back the Malazan books in the background! Also very fun video, thank you!
Your videos are awesome! Also that song at the end "cooler heads" by Jeremy Black is really good, thanks for introducing me to his music. Super smart/insightful and great taste in music, double threat (among other talents I'm sure)!
Love this channel and your videos thank you
thank you for making my intro quantum mechanics course relevant to something cool (understanding a new concept + getting one of your high level videos)
