The "taxon cycle" is a concept used in biogeography and ecology to describe the natural evolutionary and geographical progression of certain species or taxa over time. It outlines how populations of species move through a predictable series of stages as they adapt to changing environments, often in response to factors such as habitat availability, climate change, or other ecological pressures.

On the coast between Los Angeles and San Francisco, closer to Los Angeles. Home of UCSB.

It is quite comical that two separate towns were founded one next to the other right in the middle of nowhere. And that both have so slightly weird names.

In the context of general relativity and the canonical formulation of the theory, the Hamiltonian constraint is a fundamental equation that arises in the process of quantizing gravity. It plays a key role in the framework known as Hamiltonian formalism or the ADM (Arnowitt-Deser-Misner) formulation of general relativity.

Spin foam is a concept that arises in the context of quantum gravity, particularly in the framework of loop quantum gravity (LQG). It is a way to describe the evolution of quantum states of geometry over time. In this framework, spacetime is not treated as a smooth continuum but rather is represented by discrete structures.

Warp drive theory is a concept in theoretical physics and science fiction that describes a method of faster-than-light (FTL) travel. The most well-known depiction of warp drive comes from the "Star Trek" franchise, where starships are able to travel great distances across the galaxy by using a warp drive engine. The underlying principle in many theoretical models of warp drive is based on manipulating space-time itself.
