Fermi–Dirac statistics, an Uncommon card
Fermi–Dirac statistics is a type of quantum statistics that applies to the physics of a system consisting of many non-interacting, identical particles that obey the Pauli exclusion principle.

Fermi–Dirac statistics quiz: 3 questions
Three questions on the Fermi–Dirac statistics card, the way WikiCards duels ask them. Pick an answer, the facts are just below.
Find the missing word
A result is the Fermi–Dirac distribution of ______ over energy states.
Answer
particles. A result is the Fermi–Dirac distribution of particles over energy states. From the Fermi–Dirac statistics article on Wikipedia.
In which decade?
It is named after Enrico Fermi and Paul Dirac, each of whom derived the distribution independently in ____.
Answer
1920s. It is named after Enrico Fermi and Paul Dirac, each of whom derived the distribution independently in 1926. From the Fermi–Dirac statistics article on Wikipedia.
Which of these cards hits hardest (highest ATK)?
Answer
Phase transition. Phase transition 79 · François-René de Chateaubriand 74 · Fermi–Dirac statistics 70 · Plastic explosive 66 ATK in WikiCards.
In a duel, each round asks a question like these about the opposing card, with 15 seconds to answer.
The facts on the card
The card carries these facts from its Wikipedia article.
- A result is the Fermi–Dirac distribution of particles over energy states.
- It is named after Enrico Fermi and Paul Dirac, each of whom derived the distribution independently in 1926.
- Fermi–Dirac statistics is a part of the field of statistical mechanics and uses the principles of quantum mechanics.
Why it is Uncommon
Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Fermi–Dirac statistics article was read about 83,000 times in a year. ATK comes from the length of the article and DEF from its quality, so this card hits with 70 and blocks with 64: each hit it takes is cut by 26 %.
How to get Fermi–Dirac statistics
Open packs. Each pack holds five cards drawn from real Wikipedia articles, the rarest last, and the fifth card is always Rare or better. The odds are shown in the game. A free pack arrives every hour and two can wait, and the Coins you win in duels buy more packs.
