CORE DEFINITION

Phase: different states of matter (solid, liquid, gas, etc.). Diagram: the stable regions of each phase under different conditions (temperature, pressure, etc.). Phase boundary: the boundary line between different phases.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

Visualization of state conditions. Quickly determine the state of a substance under specific conditions and predict the impact of condition changes.

Second Law of Thermodynamics

The second law of thermodynamics is one of the four fundamental laws of thermodynamics, stating the irreversibility of thermodynamic processes—isolated systems spontaneously evolve toward thermodynamic equilibrium, the state of maximum entropy. Similarly, a perpetual motion machine of the second kind is impossible. The history of this law can be traced back to Nicolas Carnot's research on the efficiency of heat engines and his Carnot theorem proposed in 1824.

Coherence

In physics, coherence (also called phase coherence) states the possibility of interference between two waves. Two monochromatic beams from the same single light source always interfere with each other. If two wave sources have the same frequency and waveform, they are coherent. The physical sources of coherent waves are not strictly monochromatic; they may be partially coherent. However, beams from different physical sources are mutually incoherent.

The Great Filter

The Great Filter theory is a hypothesis that attempts to explain the Fermi Paradox. It posits that in the development of life, from its early origins to the highest level on the Kardashev scale (Type III, capable of utilizing all resources of its galaxy), there exist certain developmental barriers (referred to as 'filters'). Consequently, extraterrestrial life detectable by humans is extremely rare. The concept was proposed by Robin Hanson: the absence of any extraterrestrial civilizations in the observable universe implies that the emergence of advanced intelligent life is very unlikely. This observation is conceptualized as the 'Great Filter'.
