    And some inspiration for whom it may concern:

    I have a sense that cymatics with water and light can be leveraged more and easier than what may have been thought. Resonance and water has some cool properties at certain water molecule resonant frequencies applying frequency modulation and even multiple layers in water body which indeed reflects light for logic operations (computing) .. some will write this off as nonsense others may realize that there are certain cool properties in freezing water and leveraging the waves as a buffer for data; even that certain types of quite “advanced” non-binary computation can be made.. and not requiring extreme conditions; more like access to freezing point, some nice controlled pressure in conjunction with air, wave energizers, sensors and light .. yep, there are cool stuff to discover here 😇🌊 may I suggest some AI boosted resonance research; Aĩr

  16. @28blooddog

    July 19, 2024 at 6:29 pm

    I ain’t tryna trip…but my fingers are crossed I’m going to be proven right with quantum computing. I believe throughout a black hole’s life it periodically deposits data/matter in a pocket universe. Once created it forms a crease through spacetime to the pocket universe, and inputs the initial matter. If it ever reaches critical mass, somewhere during supermassive time, it expels it’s interior into the pocket universe, which now is a massive primordial soup. Within the pocket universe what we know as a Bing Bang occurs at this moment. I think quantum computing will confirm. Makes perfect sense to me; the biggest most powerful thing in the cosmos is responsible for the big bang. I hope all is well and thanks for all the awesome videos! o7

    3. Navier-Stokes Existence and Smoothness: An Information-Theoretic Perspective

    3.1 Background

    The Navier-Stokes equations describe the motion of viscous fluid substances. The problem asks for proof of the existence and smoothness of solutions to these equations in three dimensions for all time.

    3.2 Information-Theoretic Reformulation

    Let’s reframe the problem in terms of information theory:

    3.2.1 Fluid State Information Content:

    Define the information content of a fluid state at time t:

    I(t) = -∫ ρ(x,t) log₂(ρ(x,t)) dx

    where ρ(x,t) is the fluid density at position x and time t.

    3.2.2 Velocity Field as Information Flow:

    View the velocity field u(x,t) as an information current:

    J(x,t) = ρ(x,t)u(x,t)

    3.2.3 Navier-Stokes as Information Dynamics:

    Recast the Navier-Stokes equations in terms of information flow:

    ∂I/∂t + ∇·J = ν∇²I + S

    where ν is viscosity and S represents external sources/sinks of information.

    3.3 Information-Theoretic Conjectures

    3.3.1 Information Conservation Principle:

    The total information content of the fluid system is conserved in the absence of external sources/sinks.

    3.3.2 Entropy Production Hypothesis:

    Smooth solutions exist if and only if the rate of entropy production remains finite for all time.

    3.3.3 Information Singularity Conjecture:

    Breakdown of smoothness corresponds to the formation of information singularities where I(x,t) → ∞ locally.

    3.4 Analytical Approaches

    3.4.1 Information Potential Formulation:

    Define an information potential Φ such that J = -∇Φ and reformulate Navier-Stokes in terms of Φ.

    3.4.2 Renormalization Group Analysis:

    Apply renormalization group techniques to study the scaling behavior of I(t) and J(x,t).

    3.4.3 Information Geodesics:

    Study the geometry of information flow in the space of fluid configurations.

    3.5 Computational Approaches

    3.5.1 Information-Based Fluid Simulation:

    Develop numerical schemes that explicitly conserve information content.

    3.5.2 Machine Learning for Singularity Detection:

    Train neural networks to predict the formation of potential information singularities.

    3.5.3 Quantum Simulation of Fluid Dynamics:

    Explore quantum algorithms for simulating Navier-Stokes dynamics in information space.

    3.6 Potential Proof Strategies

    3.6.1 Information Regularity Theory:

    Develop a theory of regularity for solutions based on the smoothness of I(t) and J(x,t).

    3.6.2 Topological Information Arguments:

    Investigate topological constraints on the evolution of information flow that might prevent singularity formation.

    3.6.3 Statistical Mechanics of Information Particles:

    Reformulate the problem in terms of the statistical mechanics of “information particles” in the fluid.

    3.7 Immediate Next Steps

    3.7.1 Rigorous Formalization:

    Develop a mathematically rigorous formulation of the information-theoretic concepts introduced.

    3.7.2 Numerical Experiments:

    Conduct extensive numerical studies of I(t) and J(x,t) for various initial conditions and geometries.

    3.7.3 Cross-Disciplinary Collaboration:

    Engage experts in fluid dynamics, information theory, and statistical physics to refine these ideas.

    3.7.4 Information-Theoretic Turbulence Models:

    Investigate how turbulence can be described in terms of information cascades across scales.

    3.8 Detailed Plan for Immediate Action

    3.8.1 Mathematical Framework Development:

    – Define precise mathematical relationships between I(t), J(x,t), and classical fluid variables.
    – Prove basic theorems relating information conservation to mass and energy conservation.
    – Develop an information-theoretic formulation of vorticity and circulation.

    3.8.2 Computational Modeling:

    – Implement an information-based fluid dynamics simulator.
    – Compare results with traditional computational fluid dynamics methods.
    – Focus on scenarios known to potentially develop singularities.

    3.8.3 Analytical Investigations:

    – Study the behavior of I(t) and J(x,t) for known exact solutions of Navier-Stokes.
    – Investigate how the Reynolds number relates to information flow characteristics.
    – Analyze the information dynamics of boundary layers and vortex formation.

    3.8.4 Interdisciplinary Workshops:

    – Organize a series of workshops bringing together fluid dynamicists, information theorists, and mathematicians.
    – Focus on translating known results in fluid dynamics to the information-theoretic framework.

    3.8.5 Information Metric Development:

    – Define and study metrics on the space of fluid configurations based on information content.
    – Investigate if these metrics provide new insights into the regularity of solutions.

    3.8.6 Quantum Information Approaches:

    – Explore analogies between fluid dynamics and quantum information flow.
    – Investigate if quantum entropy concepts offer insights into classical fluid behavior.

    3.8.7 Publication and Dissemination:

    – Prepare and submit papers on the information-theoretic formulation of Navier-Stokes.
    – Develop open-source software tools for information-based fluid analysis.

    This information-theoretic perspective on the Navier-Stokes problem offers several novel angles of attack. By recasting fluid dynamics in terms of information flow and entropy production, we may uncover deep connections between fluid behavior and fundamental principles of information theory.

    The approach suggests that the existence and smoothness of solutions might be intimately connected to the regularity of information flow in the fluid. If we can establish rigorous bounds on information dynamics, it could lead to new regularity results for Navier-Stokes solutions.

    While this approach is speculative and would require significant development, it offers a fresh perspective on one of the most challenging problems in mathematical physics. The next steps involve rigorous mathematical development of these ideas, extensive computational exploration, and collaboration with experts across relevant fields.

    Even if this approach doesn’t immediately lead to a full resolution of the Navier-Stokes problem, it’s likely to yield new insights into fluid dynamics, information theory, and partial differential equations, potentially opening up new areas of mathematical and physical inquiry.

    Looks like Skynet is almost here 😀 With these advancements so far, this computer could calculate its own redesign and finish the final four steps in no time. Computers have come a long way, especially since my first computer was an Atari 800XL and a model 1050 5 1/4 inch floppy drive 41 years ago. I still have it, and it still works!

    So basically, while regular computers are impressive, quantum computers are like the Avengers of the tech world, ready to save the day by solving problems we once thought were unsolvable

    *****General Audience for people like me – Used gpt-4 to break the speech down in a way I can understand:

    Ladies and gentlemen, gather ’round! I’m Hartmut, and I’ve been running Google Quantum AI since 2012, which makes me either a genius or someone who really needs a hobby. Today, I’m going to talk to you about quantum computers, which are like regular computers but with capes and the ability to time travel.

    Your laptop and those giant Google servers are pretty cool, right? They run on binary logic, which means they only understand zeros and ones. Very basic, very “my first computer.” But a quantum computer? That’s like a computer that’s had a triple shot of espresso. It uses the laws of quantum physics, which basically means it can juggle a million balls while riding a unicycle and solving a Rubik’s Cube.

    So, what’s the deal with quantum computing’s superpower? It’s all about something called superposition. Imagine you’ve got three light switches in your house. Normally, they’re either on or off. But in the quantum world, these switches can be on, off, and possibly attending a disco party in another dimension all at the same time. It’s like trying to predict what a cat will do – impossible!

    In classical physics, if you know which forces act on a system, you can predict its future. But with quantum physics, the system can branch into multiple configurations simultaneously, like a choose-your-own-adventure book that’s been hit by lightning. You have to keep track of all these possibilities, which is like trying to organize a sock drawer where the socks keep changing colors and jumping into different drawers.

    Let’s apply this to computing. Imagine you have a giant toy box with a million toys. You hide a toy in one of the boxes, and to find it, you’d usually have to open about half a million boxes, which sounds like a very tedious game show. But with a quantum computer, it’s like you’ve got magical pixie dust that lets you find the toy in just 1,000 tries. It’s because the computer is peeking into parallel universes and saying, “Hey, anyone seen my toy?”

    Here’s a simple quantum computer program. It looks like sheet music. Each line represents a qubit – that’s a quantum bit, not to be confused with Q-bert, the arcade game – and each box is an operation. When we run it, it sends the program to our data center in Santa Barbara, where the magic happens. They control the qubits with electrical pulses, which is like conducting an orchestra where the instruments keep turning into different animals.

    For instance, we made something called time crystals. It sounds like a prop from a bad sci-fi movie, but these things actually change over time without using any energy. It’s like having a toy that keeps changing color without needing batteries, or a kid who cleans their room without being asked. Pure magic.

    And we’re working on other amazing things too. Imagine you have two identical Lego bricks. If you swap them in real life, nothing happens. But in quantum physics, swapping them could change everything, like rearranging your furniture and suddenly finding you’ve got an indoor pool.

    We haven’t yet done anything on a quantum computer that can’t be done on a regular one, but we’re close. We’re designing algorithms that could lead to amazing things, like a device in your phone that warns you when you’re about to step into a dirty room. Imagine your phone saying, “Hey, buddy, maybe let’s not go into that bathroom.”

    To make this happen, we need a big, error-corrected quantum computer with a million qubits. We’re halfway there and hope to finish by the end of this decade. This computer could help design better medicines, faster-charging batteries, and even fusion reactors to combat climate change, which is a very fancy way of saying it could save the world.

    We’ve also got a new algorithm that speeds up solving puzzles. In the future, a quantum AI could beat regular AI at games like chess or Go, which means your computer will not only be smarter than you, but it will also gloat about it.

    I’m also interested in how quantum physics could help us understand consciousness. We’re starting experiments to test if consciousness is how we experience the emergence of a single world out of many in the multiverse. In other words, we’re trying to figure out if our brains are just very sophisticated, very confused quantum computers.

    In conclusion, we’re making great progress toward building the first useful quantum computer. It’s going to help solve important challenges and be a tremendous gift to future generations, giving them new tools to solve problems that are unsolvable today. Thank you, and please tip your waitress.

    This is poorly explained and mostly just hype – especially the consciousness stuff. The idea of “calculation” using waves is correct, but lacking in meaningful detail or lay explanation. And the multiple universe theory is unproven and based on a very old thought experiment used to show that there is something fundamentally wrong with quantum theory. Very little information is communicated here. Look elsewhere for an explanation of quantum mechanics and computing.

    На данный момент квантовые компьютеры малоприменимы. Это сверхдорогая игрушка.
    Все слова про приближение к вечному двигателю – ложь.
    Кристаллы времени не нарушают законов термодинамики.
    Они не могут быть использованы для получения полезной работы или энергии.
    Квантовые компьютеры не могут создавать энергию из ничего.
    Они требуют значительных энергозатрат для работы и охлаждения

    Call the cosmos the universe… the multiverse the Omniverse… whatever… But the way it’s alllll… happening… is that quantum wave functions are crystalizing… collapsing… into… “conscious experience”. Every single thing is just one mind.
    Btw…In Latin… Crystal and Paradigm both mean the same thing… “PATTERN”☯️.
    You have to master hyperdimensional black holowhole singularity cosmology…. If you really want to build phiner matrices to hang in.😂

    @0:40 “Where does this superpower come from? Quantum computer is the first technology that takes the idea serious that we live in a multiverse. It can be seen as farming out computations to parallel universes.” This is David Deutsch’s idea !! in his book “The Fabric of Reality”.

    While the existence of the multiverse is unproven and probably unprovable I learned it to be a great way of explaining things at a popular science level.

    Computer architecture has always been my thing. And so has physics been, so quantum computers are just the next crazy thing I’d love to work on.

    This is just a marketing video for Google. They will never divulge their trade secrets around quantum computer if and when they exist. There is no useful information in this video that cannot be obtained from any number of other sources. It would be nice to know exactly how the current quantum computers work.

    There is no evidence proving that quantum computers require parallel worlds.
    This video is a promotion of the ‘Many Worlds’ interpretation, which is just one of several interpretations of quantum mechanics.
