Poisson's equation, an Uncommon card
Poisson's equation is an elliptic partial differential equation of broad utility in theoretical physics.
- Rarity
- Uncommon

- Science
- ATK

- 30

- 95
- Wikipedia reads a year

Power 95 (ATK + DEF): stronger than 55 % of WikiCards cards.
The facts on the card
The card carries these facts from its Wikipedia article.
- For example, the solution to Poisson's equation is the potential field caused by a given electric charge or mass density distribution, with the potential field known, one can then calculate the corresponding electrostatic or gravitational field.
- It is a generalization of Laplace's equation, which is also frequently seen in physics.
- The equation is named after French mathematician and physicist Siméon Denis Poisson who published it in 1823.
Why it is Uncommon
Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Poisson's equation article was read about 94,000 times in a year. ATK comes from the length of the article and DEF from its quality, so this card hits with 65 and blocks with 30: each hit it takes is cut by 12 %.
How to get Poisson's equation
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.
