Entropy
01
entropi, termodynamisk oordning
a thermodynamic measure of the degree of disorder or randomness in a system, denoted by S
Exempel
When ice melts into water at a higher temperature, the entropy of the system increases.
När is smälter till vatten vid en högre temperatur ökar systemets entropi.
Gas molecules in a container have higher entropy than the same molecules in a more ordered liquid state.
Gasmolekyler i en behållare har högre entropi än samma molekyler i ett mer ordnat flytande tillstånd.
02
a numerical measure of the uncertainty or unpredictability of an outcome or information source
Exempel
The entropy of the message stream was calculated to optimize compression.
High entropy in a password indicates greater security.
