Entropy is a fundamental concept in physics representing the degree of disorder or randomness within a system. It’s closely related to statistical mechanics and thermodynamics, describing the number of possible microscopic arrangements corresponding to a given macroscopic state. This principle expla...

Quantum entanglement is a phenomenon in quantum mechanics where two or more particles become linked. This linkage creates a correlation between their properties regardless of the distance separating them. Measuring a property of one entangled particle instantaneously determines the corresponding pro...

Manuel Castells is a Spanish sociologist known for research on cities, communication, globalization, and the social effects of information technology. His three-volume study The Information Age, published from 1996 to 1998, developed the concept of the network society to describe social and economic...

Superdense coding is a quantum protocol utilizing entanglement to increase data transmission efficiency. It enables two parties to exchange two classical bits of information by sending only one qubit. This technique relies on pre-shared entangled photon pairs and is particularly relevant for researc...

Bengt Holmström is a Finnish-American economist and professor at the Massachusetts Institute of Technology. He shared the 2016 Nobel Memorial Prize in Economic Sciences with Oliver Hart for their foundational contributions to contract theory. Holmström's research analyzes how contracts are designed...

The holographic principle proposes a fundamental connection between gravity and quantum mechanics. It posits that our three-dimensional universe may be fundamentally described by information residing on a distant, bounding surface. This concept, rooted in black hole physics, suggests that all the da...

Armen Alchian (1914–2013) was an American economist who spent his career at the University of California, Los Angeles. He made contributions to property rights theory, the economics of information, and evolutionary approaches to economic behavior. Alongside Harold Demsetz, he helped define the UCLA...

Ricardo Reis is a Portuguese economist at the London School of Economics, known for developing the sticky information model in macroeconomics. In this framework, economic agents update their information sets only periodically rather than continuously, offering an alternative to the sticky-price assu...

A qudit is a generalization of the qubit, representing a quantum system with *d* possible states—where *d* is an integer greater than or equal to two—and enabling richer computational possibilities than qubits alone.

Fog of War Chess, also known as Dark Chess, is a variant where players can only see squares their own pieces could move to or attack, creating significant information asymmetry. Unlike standard chess with complete information, this variant requires players to develop strategies based on limited know...

Dark Chess is a chess variant using fog-of-war mechanics in which each player can see only the squares occupied or attacked by their own pieces. Unlike Kriegspiel, it generally requires no referee, with legality enforced by the game software or app. Moves are submitted normally, and attempting an il...

A qutrit is a fundamental unit of quantum information in quantum computing, representing the base-3 equivalent of a qubit. While a classical bit exists in a state of 0 or 1, and a standard qubit exists in a superposition of two states, a qutrit can exist in a superposition of three distinct states....

Kriegspiel is a chess variant in which neither player can see their opponent's pieces, creating a game of incomplete information. A referee manages the board and announces only what is necessary: whether a proposed move is legal or illegal, whether a capture has occurred and on which type of square,...

Though unfinished, this symphony is beloved for its profound, beautiful melancholy and exquisite lyricism. It captures a sense of yearning and unresolved beauty, making it deeply moving. The music flows with Schubert's signature melodic gift, creating an atmosphere of wistful contemplation that reso...

Die Jakobsleiter (Jacob's Ladder) is an unfinished oratorio by Austrian composer Arnold Schoenberg, begun in 1922 and abandoned in 1923. The work sets a text written by Schoenberg himself, depicting a spiritual journey toward God as souls ascend through various stages of consciousness. Despite remai...

Christus is an unfinished sacred oratorio by Felix Mendelssohn. The composer intended it to portray episodes from the life of Jesus Christ, including material associated with the Nativity and the Passion, but he died in 1847 before completing the work. What survives consists of separate musical sect...

Camouflage Chess is a hidden-information variant where pieces appear identical to opponents until they move or are captured, heavily emphasizing psychological bluffing and deductive reasoning.

Screen chess, also known as Kriegspiel, is a chess variant in which the players cannot see each other's pieces because a screen or divider separates the boards. A referee records legal moves and reports information such as captures, checks, and attempted illegal moves. The game is intended for playe...
