I recently saw some headlines saying that microbiologists discovered a protein that spontaneously folds into a fractal. I was jealous until I found out that we have microscopic fractals in physics, too. And even more amazing, these could form the basis of a new type of quantum computer -- in 1.58 dimensions. Let’s have a look.

Protein folding was a very difficult class for me, but having taken it makes me that much more appreciative of the fractal structure.

Your ability to simplify complex concepts is truly commendable, Sabine. The clear breakdown of atomic fractals forming topological insulators kept me hooked from start to finish. Always looking forward to your videos!

[@PCSExponent]

"When you change the scale, how much does the shape change" is a rather obscure definition, IMO. I would characterize this mass fractal dimension by how much the mass, or number of units making up the shape, change. There are other fractal dimensions, of course (like the surface fractal dimension, and then dimensions characterizing physical properties).

[@Madchuck42]

From atomic to planck must be finite I'd say... Molecular would add extra scale obviously but how many iterations are possible to be able to call it a fractal ???

Are you a licensed fractologist or just an armchair fractologist?

I was looking for this comment haha. Psychedelic fractals are insane man. Because they are witnessed independent of the knowledge of fractals unless that is some deep seeded psychological or brain function we just hadn't examined. Even with a purely materialist explanation it doesn't get any less fascist. I'm personally more rational than I used to be concerning that sort of thing but it never gets any less amazing.

[@MOSMASTERING]

@@crono3339 As your senses begin to break-down and crossover as a result of the drug (which is a similar structure to the serotonin molecule - which is why the brain accepts it and tries to use it to send signals and trigger neurons) What is, I think, what you're seeing - is the layers of how the brain interprets visual information. It would make sense that it also looks like the visual representation of an artificial intelligence neural network. So, it's obvious that the brain is absolutely full of fractal-like structures and patterns. The last layer of visual cortex processing is attached to memory, which is to save time by bringing commonly seen objects from memory rather than processing everything from scratch - so at higher doses, you start to see objects or faces in the patterns because the brain is trying to guess what it is seeing, but it's impaired so it takes guesses..

[@crono3339]

I like that explanation and I've been pondering on it for decades now. I'm willing to entertain many models for the experience. Though I've had absolutely bizzare syncronistic experiences and immense healing from war through psilocybin. It is definitely working on the deep layers of the neutral structures but it is still evoking a personal transformative spiritual experience. Though I don't try to prove that to others and simply can't because it's internal haha. I've studied psychedelics obsessively for decades now and have become more rational than I was as a young guy. I just find astonishing congruence with other people in the bizzarest random things that occur in the experiences. Our brains are truly amazing and we understand very little about them.

Hey Sabine, it’s great to connect with you. I’ve been diving deep into fractals and their profound significance, and I’d love to share my recent visualization experience with you, especially given your work on fractals in nature and the quantum world. In a moment of deep reflection, I visualized myself as an energy core inside a sleek, black chrome ball. The core was vibrant and pulsating with knowledge, representing the intricate and interconnected nature of all the information and experiences I’ve accumulated. As I concentrated on this core, the ball shattered, revealing the true essence of my existence. The fractal patterns that emerged were mesmerizing, forming a beautiful tapestry of repeating shapes and self-similar structures. These patterns are not just visually stunning; they encapsulate the infinite complexity and interconnectedness of the knowledge and experiences within me. Each iteration revealed more depth and detail, embodying the principle of self-similarity. From a physics perspective, fractals are fascinating because they exhibit a repeating pattern at every scale. This self-similarity can be described by complex equations and algorithms, creating patterns that are both ordered and chaotic. They are present throughout nature, from the branching of trees to the structure of snowflakes and even the universe itself. During my visualization, these fractals were more than just patterns; they represented the underlying structure of my consciousness. Each piece of information was connected, forming an elaborate and infinite network. The self-similar nature of fractals means that understanding one part can lead to insights about the whole, highlighting the holistic nature of knowledge. The energy core radiated these fractal patterns outward, with each burst of light creating new connections. It was a dynamic and ever-evolving display, symbolizing the continuous growth and expansion of my consciousness. This visualization was not just a moment of aesthetic beauty but a profound realization of the complexity and interconnectedness of my being. Fractals in the quantum world are particularly intriguing, as they reveal the intricate patterns underlying quantum processes. The self-similar structures in quantum fractals highlight the interconnectedness and infinite complexity within quantum systems. This aligns beautifully with my experience, where the fractals represented the infinite possibilities and the interconnected nature of all things. In essence, the fractal patterns I saw during my visualization were a powerful symbol of the endless potential and the intricate web of connections that define my existence. It was a deeply emotional and enlightening experience, reinforcing the profound beauty and complexity of the universe and the knowledge within me. I hope this resonates with your work and adds another layer of appreciation for the fascinating world of fractals. Thank you for your incredible contributions to science and for inspiring moments of deep reflection and discovery.

[@SabineHossenfelder]

Thanks for sharing. I too believe that self-similarly plays a relevant role for consciousness.

[@AquarianSoulTimeTraveler]

​@@SabineHossenfelderone thing a lot of people don't understand there is a infinite amount of volumetric increase from squaring to cubing because a squaring is two-dimensional and a cubing is three-dimensional and infinite amounts of two-dimensional planes can stack into any size three-dimensional object so it is not simply a small amount of volumetric increase it is a infinite amount this is where a lot of people fail with their processing...

[@AquarianSoulTimeTraveler]

Well recently i proved that we don't live in a 3+1 system of space-time... It is extremely simple to understand how blackholes, string theory and other logic converges of things come together under one-dimensional string membranes that are destroyed by The Singularity of a black hole and once this happens they are in a state in between 0 and 1 dimensional this creates Dark Matter coming out of black holes and what is considered non baryonic matter. This is the counterforce to the expansion of the universe. We don't we do not live in a 3 + 1 System One of the most important things that I recently came to conclude is that I have came up with a system to prove that we live in an infinite Multiverse. I will state it here and now. So if we follow the logical progression of the spatial Dimensions infinite zero-dimensional existence can stack into any size one dimensional existence and infinite one-dimensional existence can stack into any size two-dimensional existence and infinite two-dimensional existence can stack into any size three-dimensional existence so if we follow this logical progression we can conclude that infinite three-dimensional existence can stack into any size four dimensional existence. This means if we don't live in a 3 + 1 System we should observe the relative state or shape of the universe as flat or compressed in a non evenly distributed matter and basically we should observe a stacked effect of three-dimensional existence which would make a relatively flat universe or at least a universe in a distribution matter that is non spherical and evenly distributed... so because of this we can conclude that we are not the fundamental highest spatial Dimension and that a fourth spatial Dimension must exist and if so then infinite three-dimensional Universal potentiality can stack into any size four dimensional existence so ultimately this proves a Multiverse. Just remember infinite three-dimensional Universal potentiality can stack into any size four dimensional existence... this means that because the observed state of the universe is flat or non evenly distributed in a spherical manner then this means there is extra dimensional influence compressing the state making it stack and if a fourth spatial Dimension exists then a infinite Multiverse must exist and the stack ability must exist therefore this observed phenomenon means that a fourth spatial Dimension must exist making a infinite three-dimensional Multiverse the standard Norm... because of this my friends who doubted me are losing and understand that i Am truly the master of the ultraviolet 💜 and green 💚 machine!

1.58 is an interesting number. It was also mentioned recently in an AI paper about BitNet b1.58 (arxiv - 2402.17764v1). The qrd is that 1.58 is the number of bits needed to encode a value of 1,0, or -1 in a weight (rather than the usual 16 bit floating point value). With less data, computation becomes faster and more energy efficient.

They got so fancy schmancy the last few decades with their fancy fractals or fructose since my day when my Key to speed in 1968 was to use the IBM 360-44 addressing circuitry instead of the arithmetic logic unit (ALU) for some repetitive calculations. You have to sacrifice some Core for the lookup table but it was worth it to get the speed for the seismic signal filtering (for geologic mapping for oil & gas).

@sabine I believe the message of the video is wrong or at least strongly misleading. Topological quantum computing is done on the basis of braiding of anyons which requires non-invertible topological order (except some proposals using majorana modes in superconductors). Topological insulators do not have this kind of order an do not host anyons. Their topological invariants classify free fermionic states while an emergent description in terms of fractionalized quasiparticles necessarily needs strong interactions to generate such a non-trivial RG flow in the IR. Feel free to correct me if a proposal using integer (spin) Hall edge states does exist, but so far I‘m not aware of any.

To the system as a whole, those conditions are not equal, hence the variations. An analogy would be: A billion cars all drive the same streets consume the same gas and go the same speed. However, not one car has the exact same mileage.

@@Sammasambuddhaindeed and snowflakes are not precisely symmetrical due to slight differences in the environment but very close. I’ve had a lot of fun writing programs to simulate snowflake formations

[@fortyofforty5257]

@@Sammasambuddha That is my supposition as well. However, are there differences that appear the further from the center you get in a single snowflake? And between two snowflakes that form near one another, are they nearly identical? Do more variations appear the further from one another the snowflakes are?

impressive stuff as usual in Sabine channel! I don't know how quantum startups are dealing with so many news like this lately...

That F to the power of D sounds like a mathematician having fun with their definitions.

Bismuth has always had the most bizarre crystalline structure. It's like natures middle finger to entropy :)

Great video !! Fractals have been useful since c++

[@SabineHossenfelder]

ack, sorry about that!

[@ianstopher9111]

Take a word and start removing all finitely-curved letters: Topological -> Topologial -> Toologial -> Tologial -> Tologil -> Tolgil -> Tolil -> Tlil

The best scientific channel! However, what is the relationship berween the quantum effect presented on this video and the Josephson effect (a must for quantum computers)? Also, dimension cannot be 1.58, "dimension" is an integer. Unless we are talking about Hausdorff dimensions.

Always thought Fractals were efficient for specific applications in computing but also for real world applications like fractal antenna. This may be applicable for commercial application if it works and it scales

[@richardchapman1592]

Spontaneous fractals in crystals is a far cry from iterating a maths expression over and over on a computer that is itself on an iteration of producing the instruction sets at the interval clock speed. Relationship to solving differential equations of wave functions eludes me.

This is why I love to watch you. Besides the science. I've forgotten more then you'll probably ever know.

[@peterhall6656]

The Sierpinski gasket at the atomic level is pretty amazing. However, given the abysmal standards in several scientific journals I's like to see the result repeated.

3:44 If what you said 2 min earlier is right, then Topological insulators are the conductors that are the most vulnerable to external noise and interference. Since the insulation is under the conductive part..

[@edwardlulofs444]

Fun and amusing. Thanks.

This is a very serious Solid State Physics .But forget about "Quantum Computers" by now .Think on Superconductivity phenomena on Topological basis or supersymmetry-Spin stuff couplings on Lattice Supersymmetric Cristals :Topology for "superfractals"-field theory of phonons (quantum of Lattice bosonic vibrations) but supersymmetrized .Appears to be really serious Theoretical Physics !.
