A lens can perform the Fourier transform! 🔍 This is the 4F system: the first lens converts an image into its frequency components, and the second lens reconstructs it. By adding an aperture at the Fourier plane, we can filter out high frequencies. #Optics #Physics #b3d

Spherical Harmonics 🤝 Fourier Transform I’m modeling the cell surface as a time-varying field u(θ,φ). Budding is energy shifting into higher angular frequencies. Decompose u into spherical harmonics (the Fourier basis on a sphere), evolve the coefficients aₗₘ(t) where growth/smoothing is clean, then inverse-transform back into a breathing, budding 3D surface. #SphericalHarmonics #FourierTransform #HarmonicAnalysis #SpectralMethods #SignalProcessing #AppliedMath #MathAnimation #ScientificVisualization #Biophysics

When LIGHT passes through a PRISM, it separates into the 'colour spectrum' based on its FREQUENCY... Our BODY is made of mostly WATER 💦 acting as a prism. So when light passes through, it SEPARATES into our 7 chakras based on the frequency of light.

🚨 THIS IS WHERE I BUY BITCOIN. The cycle is simple once you see it. Accumulation. Distribution. Re-accumulation. Distribution. Then accumulation again. We just came out of distribution and into the third accumulation zone. This is the phase where strong hands quietly load up while everyone else is scared.

Visualization of the continuity equation. Showing how any change in mass density inside a fixed control volume is exactly balanced by the net mass flux through its boundary. Blue particle concentration represents, the green arrow represents velocity, and the orange arrows show mass entering and leaving. The density is redistributed, but no mass is created or destroyed.

This is a living map of a complex rational field: cool regions are root-dominant (|R| 1), where R is the complex rational function. Phase stripes come from arg S (the logarithmic derivative of our complex field R) and particles surf the Newton flow. 🤩🤗😍

Five layers. Seventeen minutes. One structure built to last for decades. This is Stage 4: Lamination. Heat, vacuum pressure, and precision engineering transform glass, EVA, and solar cells into a fully sealed solar module ready for the next phase of production. This is where individual components become energy infrastructure.

The formula for Time Travel that was given to Van Tassel from the Nordics… Was F = 1/T If frequency (F) is inverse time (T)… Then manipulating frequency is manipulating temporal relationships. higher frequency = shorter periods of time lower frequency = longer periods If matter, biology, and consciousness are fundamentally oscillatory… And oscillation defines temporal behavior… Then manipulating frequency might alter how systems experience time.

.Google DeepMind Gemini 2.5 Pro is really helpful for education. Simply we can turn any idea, concepts into interactive web components! Here is an example for NVIDIA Dynamo. Complex visualization was a technique that only small number of people could handle. Now we all have it.
