门捷列夫不等式
门捷列夫除了创立元素周期表外，还发现了一个有趣的数学定理。他从插值问题出发，推导出关于多项式及其导数的定理，这一成果后来被Boas等学者引用和推广。

The article presents the exact closed-form solution for the nonlinear (large-angle) pendulum using Jacobi elliptic functions, contrasting it with the common small-angle approximation that uses sine functions. It explains how the exact solution involves elliptic integrals and Jacobi sn, cn, and dn functions, providing formulas for the angular displacement and period.
Researchers have developed an ultra-fast method for generating 1024-bit prime numbers using the Hilbert-Pólya spectral law. This approach significantly accelerates prime generation compared to traditional methods while maintaining cryptographic security standards.
The article discusses how the nonlinear behavior of a pendulum deviates from the simple harmonic oscillator approximation, particularly at large amplitudes where the period depends on the amplitude. It explains that this nonlinearity means the small-angle approximation (sinθ ≈ θ) breaks down, leading to longer periods than predicted by the linearized model.
A project argues that fundamental musical elements such as notes and harmony are not primitive building blocks but emergent structures. It introduces the concept that pitch is essentially rhythm sped up. A NotebookLM-generated podcast further explores these ideas.
This GitHub repository presents an analysis of prime gaps, examining the statistical structure and distribution of gaps between consecutive prime numbers. It includes data visualizations and computational results exploring patterns in prime gap sequences.
