Physics likes optimization! Subject to its boundary conditions, the time evolution of a physical system is a critical point for a quantity called an action. This point of view sets the stage for Noether's principle, a remarkable correspondence between continuous invariances of the action and conservation laws of the system.
In 1960 physicists finally verified Einstein’s 1911 prediction that gravity could change light’s frequency. Understanding the effect is essential to modern navigational technology.
What would the world look like if you could see beyond the the rainbow? Filmed using an infrared camera, this is London as you’ve never seen it before. This is how the Dune 2 team got the epic Harkonnen arena fight scene on Arrakis to look so incredible—Feyd-Rautha (Austin Butler) isn’t really that pale, but filming in IR increases the pallor and smoothness of skin, as you can see if you watch the video. Kudos to director Denis Villeneuve for bringing IR to the cinematic mainstream as something other than a night-vision effect!
The best demonstrations of physics are those that show you something completely unexpected and counter to the way that physics is supposed to work. One of my favorites is this curious contraption, which I got through a Kickstarter a few years ago: This is what is known as a tensegrity table, which demonstrates the phenomenon…
Island management is a fundamental low level feature of physics engines and can have a big impact on solver design and performance. This was one of the first problems I decided to work on for Box2D version 3 (v3). Since I began working on v3 I've been comparing several algorithms for island management. My goal has been to make island building scale better with multiple CPU cores. Here are the three approaches I've considered:
