Physics Schrödinger Equation for One-dimensional Coulomb Potential This article presents an unconventional solution to the Schrödinger equation in the presence of a one-dimensional Coulomb potential. 2024.10.08 Physics
Analysis Distance on a Sphere This article considers distances on a sphere and compare their properties with those in Euclidean space. We present the hypothesis that distances in gravity may not be exactly distances in Euclidean space, but may be approximations of distances on a sphere. 2024.10.02 Analysis
Physics Gravity in One-dimensional Space This article considers gravity when space is one-dimensional. I believe that by expanding this to what happens when it becomes two-dimensional, and then three-dimensional, I will be able to arrive at the true essence of gravity. 2024.09.24 Physics
Analysis Numerical Solution of Ordinary Differential Equations This article will provide an overview of the Euler method and the Runge-Kutta method as numerical methods for solving ordinary differential equations with initial conditions. For equations that cannot be solved analytically, we will use numerical methods to explain them. 2024.09.18 Analysis
Physics Elliptical Motion in the Theory of Relativity This article derives an equation of motion equivalent to the Schwarzschild solution from the theory of analytical mechanics in a conical coordinate system. 2024.09.13 Physics
Probability Probability Distribution on the Sphere This article consider a probability distribution that is uniformly distributed on a sphere. In the case of a two-dimensional sphere, the probability distribution of each coordinate has a uniform distribution, and has some interesting properties. 2024.09.08 Probability
Physics Two-body Problem This article consider how the equations of motion for elliptical motion in classical mechanics, known as the two-body problem, can be formulated by rewriting the equations as if two masses were moving independently. 2024.09.03 Physics
Probability How Machine Learning Works Although it may seem a little late to be saying this, I feel like I've finally come to understand what makes machine learning different from other data analysis methods such as regression analysis and how it works, so I'll give a brief explanation here. 2024.08.30 Probability
Physics Schrödinger Equation in the Free State (3 Dimensions) In this article, we derive the solution to the three-dimensional Schrödinger equation when we consider a Gaussian wave packet model (white noise model) in the same way as in the one-dimensional case. 2024.08.25 Physics
Physics Motion and Energy in the Theory of Relativity Consider the hypothesis that the space-time of the theory of relativity is a conical coordinate system. We will summarize the discussion of what the equations of motion and conserved quantities are under this hypothesis, and show the problems. 2024.08.18 Physics
