@dralexisstephens: The scalp is skin too and just like the skin on our face, it’s exposed to factors that can contribute to premature biological aging. As a dermatologist, I love the science behind @k18 new FutureIQ™ serum and the idea of bringing the same longevity mindset we’ve embraced with our skin to our scalp and hair. It’s time scalp care caught up to skincare. @K18 Hair @Sephora #k18results #K18partner #k18hair

Divine Time Healing :

so thisss is why my hair feels so tight and overstimulating and also the grays omggg. this has been so annoying lately is this a product that can reverse this?

I updated my Schrödinger Equation visuals. This time, I included the unbounded inner product Gaussian in the first 2 animations, and used the more familar localized inner product on the last. To review: The Schrödinger equation is one of the cornerstones of quantum mechanics, describing how the quantum state of a physical system changes over time. Here's a detailed explanation without using any equations: ### **Core Idea:** The Schrödinger equation governs the behavior of quantum systems, much like Newton's laws govern classical mechanics. Instead of predicting exact positions and velocities of particles, it tells us how the *probability amplitude* (a complex-valued function related to the likelihood of finding a particle in a certain state) evolves over time. ### **Key Concepts:** 1. **Wavefunction (ψ):** - In quantum mechanics, particles don’t have definite positions or paths. Instead, their state is described by a *wavefunction*, which contains all the probabilistic information about the system. - The wavefunction doesn’t tell us where a particle *is* but rather where it *might be* and with what probability. 2. **Time Evolution:** - The Schrödinger equation explains how the wavefunction changes with time. It doesn’t determine a single outcome but describes a smooth, deterministic evolution of probabilities. - If you know the wavefunction at one moment, the equation tells you how it will look in the next instant. 3. **Energy and Hamiltonian:** - The equation depends on the *Hamiltonian*, which represents the total energy of the system (kinetic + potential energy). - Different potentials (e.g., an electron in an atom vs. a free particle) lead to different wavefunction behaviors. 4. **Superposition & Quantization:** - The equation naturally leads to *superposition*—where a quantum system can exist in multiple states at once until measured. - For bound systems (like electrons in atoms), it predicts *quantized* energy levels, explaining why electrons occupy discrete orbitals. 5. **Uncertainty & Probabilities:** - The wavefunction’s square magnitude gives the probability density of finding a particle in a certain state. - Unlike classical physics, quantum mechanics is inherently probabilistic, and the Schrödinger equation encodes this randomness. ### **Analogy (Rough but Helpful):** Imagine a ripple spreading on a pond. The shape and motion of the ripple depend on the water’s properties (like depth and obstacles). Similarly, the Schrödinger equation describes how the

The shape and motion of the ripple depend on the water’s properties (like depth and obstacles). Similarly, the Schrödinger equation describes how the "quantum ripple" (the wavefunction) evolves based on the system’s energy landscape. ### **Interpretations:** - The equation itself doesn’t explain *why* the wavefunction behaves this way or what it "really" is—that’s the realm of quantum interpretations (e.g., Copenhagen, Many-Worlds). - It’s purely a mathematical tool that works astonishingly well to predict quantum phenomena, from chemical bonds to superconductivity. ### **Why It’s Profound:** - It replaces the deterministic trajectories of classical physics with a probabilistic framework. - It introduces wave-particle duality fundamentally: Particles are neither waves nor particles but entities described by wave-like equations that collapse to particle-like observations. #quantum #quantumphysics #quantummechanics #physics #wave #maths #mathematics #mathematician #interesting #engineering #programming #quantumcomputing #superposition #entanglement #educate #education
