Freedom of Model Building

How do scientists decide which model to use when several can fit the same data? This post follows that question through the assumptions and creative choices behind scientific models, and looks at how physical reasoning and experiments help us decide which ones deserve our confidence.

Lagrangian Mechanics

This article provides an in-depth exploration of Lagrangian mechanics, detailing its foundation in the principle of stationary action, its connection to Newtonian mechanics, and its application to complex systems like oscillating pendulums and double pendulums through elegant energy-based equations of motion

Throwing at Wall

The article provides a solution to a David Morin textbook problem, determining the optimal angle to throw a ball at a wall for maximum height based on physics principles

Optimizing Trajectory Angle

This article explores optimizing the launch angle of a projectile to maximize the area under its trajectory using calculus and physics principles

Tensor Intro

This article provides an introduction to tensors, exploring their geometric and mathematical definitions, transformation rules, notation, and applications, with detailed explanations of vectors, covectors, and coordinate system changes
