CORE DEFINITION

Transferring data physically by carrying hard drives or USB sticks on foot (wearing sneakers). Although primitive, for large data volumes (e.g., petabytes), its bandwidth can exceed fiber optics.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

Physical layer thinking. Don't blindly trust the network. When you need to transfer massive or highly confidential data, the fastest and most secure way might be to 'copy it onto a hard drive and send it by plane.' Always consider 'physical transfer' as a fallback option.

anchor

Anchor fast decisions

Manually or via physical media (hard drives, USB sticks) to move data between networks, suitable for isolated or extremely large file scenarios.

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'.
