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

The Fourier transform runs inside every MRI machine, every audio compressor, every signal processor on earth. JPMorgan pays $350K to engineers who can derive it from scratch. There is one professor alive who explains it the way nobody else can. His name is Gilbert Strang. MIT. The most brilliant mathematical mind of his generation. His textbook sits in over 10 million homes. No other person on earth holds this combination of depth and clarity in one head. He opens with one confession. The Fourier transform is unreasonably effective. It solves problems it was never designed for. The goal is not to compute it. The goal is to understand why it works at all. Then the core idea. A periodic signal breaks into pure sine waves. Each with a frequency, amplitude, and phase. The transform finds all three simultaneously. A complicated signal in time becomes a simple picture in frequency. Then 1807. Fourier invented the transform not for sound but for heat. How does warmth spread through a metal rod? In time the equation is a partial differential equation - hard. In frequency space it becomes ordinary - easy. Transform in, solve it, transform back. Then convolution. Convolution in time equals multiplication in frequency. Filtering a signal, removing noise, compressing audio - all multiplication in frequency space. Without the transform: thousands of computations. With it: a few multiplications. Then the delta function. Zero everywhere except one point where it is infinite. Integral equals one. Every mathematician in 1900 said it was not a function. Dirac used it anyway. It took 40 years to justify what engineers had been doing the whole time. Watch the moment Strang shows that the Fourier transform of a delta function is a constant - every frequency in equal measure. The more concentrated in time, the more spread in frequency. This is the uncertainty principle. Not quantum physics. A theorem about any signal at all. A signal processing engineer I know rewatched this before their first project at Apple. Said it was the first time the Fourier transform felt like a change of coordinates rather than a formula to memorize. Free on YouTube, MIT OpenCourseWare. bookmark this and watch later - after this lecture every sound, every image, and every signal will feel like a sum of sine waves waiting to be separated

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. 🤩🤗😍

$BTC looks like the shakeout is over. Months of accumulation, a brutal flush below the range, and now the reclaim is sending us into the expansion phase. I’m targeting $150K–$180K next.

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.

Visualization of the harmonic oscillator. Showing how x(t) = A cos(ωt + φ) is the horizontal projection of uniform circular motion. The spring–mass system and the closed ellipse in (x, v) phase space represent the same evolving state, while kinetic and elastic potential energy continuously exchange as the total energy remains constant.

Architecture doesn't have to be expensive or complicated to be interesting. This staircase demonstrates how simple, unconventional geometry can transform an everyday circulation element into an architectural experience. The irregular arrangement of the steps creates a strong visual rhythm while encouraging movement and interaction with the space. Beyond its visual character, the design is a reminder that function and creativity can coexist. When carefully considered, even a staircase can become a memorable feature of a building—challenging conventional ideas about how we move through and experience architectural space.

This man teaches at a community college in California. His salary: around $800,000 a year. The engineers who passed calculus because of him: $1,800,000 to start. He has more calculus students than Harvard, MIT, and Stanford combined. This is Professor Leonard's Calculus 2, Lecture 6.2. Free on YouTube. Professor Leonard has taught calculus on YouTube for over a decade. His channel has millions of subscribers across 150 countries. Every major university has students who watch him the night before their exam. Then the concept. An inverse function is a machine that undoes another machine. If a function takes 2 and gives you 8, the inverse takes 8 and gives you back 2. Finding an inverse means switching every x and y in the equation and solving for y again. The graph flips across the line y = x like a mirror. Then the problem. Sometimes it is easy to find the inverse. Sometimes it is impossible to write it explicitly. A function like 3π sin x + sin x cannot be solved for x with algebra. You have to think. What angle makes the whole thing equal to 1? You work backwards through the unit circle until the answer appears. Then the shortcut. If you want the derivative of an inverse at a point, you do not need the inverse itself. You only need the derivative of the original function. The formula: the derivative of the inverse at a point equals 1 divided by the derivative of the original function evaluated at the switched point. The inverse flips the coordinates, so you flip where you plug in. Watch the moment he shows why G prime of 8 equals 1/12 without ever writing the inverse function. Every engineering student memorizes the derivative rules. Professor Leonard's lecture is the one that shows why the inverse derivative formula is just those same rules run backwards. A software engineer at a semiconductor company in Austin said Professor Leonard's channel is the reason she passed Calculus 2 on her second attempt. She graduated, joined the company, and now makes $165,000 a year.

Complex numbers aren't imaginary. They're the only way to describe a wave that has both amplitude and phase at the same time - and every LLM processes language as exactly that kind of wave through its attention layers. The same math that describes quantum wave interference is what makes Fourier transforms work, which is what lets GPT process tokens in parallel instead of one at a time. Descartes named them "imaginary" before anyone understood what they were. 20 minutes. Bookmark & watch today. The confusion clears up faster than any textbook manages.
