The end of half term

Today’s the end of the half term, so I need a break. I won’t be blogging every day, but I’ll try to post some stuff during my school trip to CERN.

As a parting gift before our short recess, here is the simple pendulum time period equation derived using Lagrangian mechanics. I’ve also managed (at last) to derive some SUVAT equations from Lagrangians, but I might save that for a future post.

Revise well over the half-term break and stay safe.
