In this video, we explain the axial dipole electric field approximation, showing how the field behaves along the axis of a dipole and why the far-field assumption simplifies the math. Clear reasoning ...

A smarter way to find π using fake circles. This short shows a clever geometric idea that estimates pi without perfect circles, revealing why the method works and how approximation can beat precision.

Everybody is welcome to attend the public defense of Danish Kashaev of his dissertation 'Approximation via Duality in Offline ...

One of the great successes of 20th-century physics was the quantum mechanical description of solids. This allowed scientists to understand for the first time how and why certain materials conduct ...

A new study enhances hydrogen molecule predictions, achieving unprecedented precision in testing fundamental physics and ...

While building a simpler model for particle interactions, scientists made a sleek new pi. Representations of pi help scientists use values close to real life without storing a million digits. The ...

From basic math to pre-calculus, Microsoft Mathematics includes features that makes it easy to create graphs in 2D and 3D, calculate numerical results, solve equations or inequalities, and simplify ...

Pi Approximation Day 2025 is celebrated on 22 July, marking the mathematical significance of the fraction 22/7, a widely used approximation of pi. This special day honors the constant pi (π), which ...
