A sneeze. Ocean currents. Smoke. What do these have in common? They're instances of turbulence: unpredictable, chaotic, ...

In physics, there are two great pillars of thought that don't quite fit together. The Standard Model of particle physics ...

Physics and Python stuff. Most of the videos here are either adapted from class lectures or solving physics problems. I really like to use numerical calculations without all the fancy programming ...

The Lagrangian approach to physics is part of the general category of least action principles, of which the easiest to explain is Fermat's Principle from optics, which holds that light rays moving ...

According to Newton's Laws, opposing forces must equal out. This applies even to the gravitational tug between planets. Lagrangian points are where these forces cancel out.

Scientists are on the trail of a mysterious five-particle structure that could challenge one of the biggest theories in ...

Lagrange points are gravitationally balanced locations where spacecraft can perform their missions.

The grand theory of almost everything actually represents a collection of several mathematical models that proved to be timeless interpretations of the laws of physics. Here is a brief tour of the ...

Today we give thanks for the Lagrangian of the Standard Model of Particle Physics, after electroweak symmetry breaking, with no explicit Higgs boson. It's served us well for three decades, ...
