The Met is sad to have missed its target but has made clear that 2026 will finally be the year it arrests more criminals than it employs.

The title graphic from the musical Hamilton. Instead of a silhouette of Alexander Hamilton forming the tip of the large black star at the center of the image, there is a black and white image of a balding, sideburned William Hamilton.

William Rowan Hamilton was born #OTD in 1805.

His reformulation of classical Newtonian mechanics via the principle of stationary action is one of the most beautiful ideas in all of physics, and is at the heart of nearly every modern theory in physics. πŸ§ͺ βš›οΈ
