This scene asks a stranger question : What happens if the material has negative refractive index? As the electron moves through the metamaterial slab, the emitted radiation no longer follows the familiar Cherenkov geometry (see below). The energy flow forms a backward-directed cone, extending opposite to the electron's motion.... show more

Welcome to the world of metamaterials @mathelirium !! I actually work in this field, would love to trade notes and share some ideas if you're down ?! 👽🙋🤔 @grok can you please describe a few examples like FEM and BEM, and why BEM does better for BioElectricity simulation modelling? We need accuracy up to THz levels because some magic happens in biology at 0.3 THz. Also discuss recent BioPhoton work and how it relates here. Also describe Marco's work below in a sentence or two @grok 🙏🫂 >> 🤜🤛to @drmichaellevin for featuring researcher Marco Pettini ⚡🧬 🦠🔬📡Experimental evidence for long-distance electrodynamic intermolecular forces | Science Advances

Fascinating. Would same movement be expected w electromagnetism. If enabled a similar flow through material, optimized for material, can vortexes be formed? (Can vortexes be strong enough for levitation?)

This is a simulation of a Hydrogen electron described by a superposition of several highly excited Rydberg states. The superposition forms a localized quantum wavepacket that moves around the atom, spreads, splits, and later reforms as the different energy components return to phase.

Riddle: Where does the energy flow in this steady state DC circuit with a copper block? And where do the Poynting vectors point? As a bonus, extend the size of the copper block to the size of the earth.

In Finite Element Method (FEM) of Computational Electromagnetics, a complex domain is divided into many small elements, and the governing equations are approximated and solved across those pieces. Here, we demonstrate the method by using a triangular mesh to simulate an electromagnetic wave travelling through a lens.

A rocket cuts through a solved Navier-Stokes flow, forcing the fluid to separate around its body and roll into a long turbulent wake. Using the D2Q9 lattice-Boltzmann method, the scene reveals vorticity, strain, Q-criterion vortex cores and wall shear.

If sound is the HUM the (breath) of Divine Creation and movement the SPIRAL (flow), the shape the BELL (vessel)... Then is MAGNETISM the force (motion)? In an array of magnets, positive and negative fields align in UNITY and from this balance - does energy moves FREELY?

An intense pulse of laser light enters a plasma and what follows is almost unbelievable. The laser pushes plasma electron aside, carving out a charged cavity. As the plasma rushes back, it creates an electric wake that can trap and accelerate another bunch of electrons. This is known as Laser Wakefield Acceleration (LWFA) and is being explored for future accelerator Physics. For this animation, we used a reduced particle-in-cell (PIC) method, coupling particle motion to the self-consistent plasma field on a computational mesh.

A Luneburg lens bends an Electromagnetic wave without a curved boundary. Instead its dielectric constant changes continuously from the centre to the edge. This forces different parts of the wavelength to travel at different speeds. Here, we solve the full 2D TM EM wave equation on an unstructured triangular mesh using the Finite Element Method (FEM).

The Serpent 🐍 The Spiral 🌀 The Shape of Reality? "Modern science" says gravity is the BENDING of spacetime (Relativity) - mass causes curves, and ENERGY follows them. BUT, a "new" theory, Spacetime Torsional Resonance (STR), suggests that space doesn’t just bend... it TWISTS. Spirals, double helixes, and vortices, energy moves as a TORTIONAL flow. A “new” idea that might actually be ANCIENT. Across cultures, we see entwined serpents: ⚕️ Caduceus 🐉 Cosmic dragons 🌀 Kundalini 🐍 Naga, Ouroboros What if the SERPENT symbolises the "duality and motion" of energy itself - the hidden SYMBOL of life and the universe? And what science now calls “dark matter”... what the ancients knew as AETHER - the living medium of energetic flow, resonance, and CREATION?

The positron is the antimatter partner of the electron and together they form positronium... a tiny quantum system with no nucleus. We used the time-dependent Schrödinger equation to evolve the electron and positron clouds. Their motion comes from their quantum states changing over time and the color from phase.

What Shape Does Chaos Take Before It Looks Random? Take one particle moving in the Hénon-Heiles Hamiltonian H = ½(pₓ² + pᵧ²) + ½(x² + y²) + λ(x²y - ⅓y³) Its motion is forced by Hamilton’s equations ẋ = pₓ ẏ = pᵧ ṗₓ = -x - 2λxy ṗᵧ = -y - λ(x² - y²) The saddle energy is Eₛ = 1/(6λ²) Below that energy, the particle remains trapped. But a tiny packet of nearby initial conditions stretches into filaments, folds through the potential, and begins to look almost random. However, it is not random. Hamiltonian flow preserves the hidden phase-space structure. What looks like chaos in ordinary space is still a deterministic loom of energy conserved, equations obeyed, geometry stretched without being erased. #HamiltonianMechanics #ChaosTheory #PhaseSpace #DynamicalSystems #MathematicalPhysics #NonlinearDynamics #HenonHeiles #SymplecticGeometry #ScienceAnimation

A Bonus render of Electron Holography for our Quantum Mechanics Lecture Series. We’re staging a TEM-style electron holography shot as a single 3D scene. A coherent electron wave ψ(x,y,t) enters from the left as a localized packet, gets split by a thin biprism phase wedge, then bends around a central nanoring that stands in for an enclosed magnetic flux. The wave evolves by Schrödinger dynamics, so its intensity ρ=|ψ|² is literally the electron detection probability density, while the probability current j=(1/m)Im(ψ*∇ψ) acts like a conserved flow of that density across the plane. The main surface is a living whose height tracks |ψ| and whose skin color cycles with arg(ψ). On top of it, luminous current ribbons trace streamlines of v=j/(ρ+ε), so you can see how phase gradients steer the flow around the ring and back into interference. High above, a tilted detector/hologram screen shows the off-axis fringe image you’d measure (intensity after mixing with a reference wave), while a porcelain bead marks the centroid ⟨x⟩(t) and flux threads through the ring pulse in sync with the Aharonov-Bohm phase knob φ_AB(t). See our lecture series for details. #QuantumMechanics #ElectronHolography #MathematicalPhysics #Physics

A helium atom tearing itself apart. Two electrons circle the nucleus, swapping energy back and forth. Then one drops inward and kicks the other one out. Those rings rolling across the fabric are the escaping electron. Hydrogen can't do this because it only has one electron.
