Have you ever seen a movie backwards in time? How did you figure out that the time was flowing backwards? This could seem a silly question. But think about it. It strongly depends on the what process the movie was showing! If you see many pieces of broken glass coming together from different directions to build a bottle that moves against gravity, you’ll immediately know that the movie is reversed. You know that because breaking a bottle is a very irreversible process. But how would you know it if the movie shows a pendulum? Or two billiard balls colliding? Or a planet orbiting a star? The way we guess the arrow of time on irreversible processes has to do with the Second Law of Thermodynamics! Watch this quick intro to Irreversibility!

Phase Diagrams are graphic representations that help understand many physical systems such as magnets and pure substances like water. These diagrams also help us understand how dense droplets of biomolecules, called Biomolecular Condensates, form inside cells. Phase Diagrams predict under which conditions these condensates can form and also what will be their molecular concentration. Watch this quick intro to learn more! References: -Video C.

Have you ever seen a tepid cup of coffee getting hot? Or a pile of sand grains organizing themselves into a sand castle? It would be strange, right? But why? The reason is behind one of the most fundamental and general laws of physics: The Second Law of Thermodynamics.
