CORE DEFINITION

Atoms with the same number of protons (same chemical properties) but different numbers of neutrons (different masses). Some isotopes are stable, while others are unstable (radioactive).

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

Identify hidden differences. In a team, some people appear the same as everyone else (same chemical properties, capable of work), but internally they may carry 'radioactivity' (negative energy, ambition). Although no difference is visible in routine reactions, in the long term or under specific conditions, this intrinsic mass difference can have a significant impact.

Isotopes are variants of the same element with the same number of protons but different numbers of neutrons; they have similar chemical properties but different nuclear properties.

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'.
