CORE DEFINITION

A very weak attractive force between molecules (not a chemical bond). Although each individual force is extremely weak, when the contact area is large enough (e.g., gecko feet), the sum of billions of tiny forces can produce astonishing adhesion.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

Value the accumulation of micro-connections. In community operations or interpersonal relationships, do not only focus on strong ties (contracts, interests); the countless weak van der Waals forces generated by daily interactions, shared language, likes, and comments are the strongest force maintaining community cohesion.

Anchor fast decisions

Van der Waals forces are weak intermolecular attractions arising from the interaction of instantaneous dipoles and induced dipoles. The mechanism is micro-accumulation: each individual force is extremely weak, but when the contact area is large enough, the sum of billions of tiny forces can produce a remarkable total adhesion.

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.
