Euclidean space quiz: 3 questions
Three questions on the Euclidean space card, the way WikiCards duels ask them. Pick an answer, the facts are just below.
Find the missing word
For n equal to one or two, they are commonly called respectively Euclidean lines and Euclidean ______.
Answer
planes. For n equal to one or two, they are commonly called respectively Euclidean lines and Euclidean planes. From the Euclidean space article on Wikipedia.
Which of these Wikipedia articles is read the most in a year?
Answer
Solar eclipse of August 12, 2026. Solar eclipse of August 12, 2026 1,300,000 · Connacht 210,000 · Euclidean space 160,000 · Carboxylic acid 120,000 Wikipedia reads over a year.
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.
- Originally, in Euclid's Elements, it was the three-dimensional space of Euclidean geometry, but in modern mathematics there are Euclidean spaces of any positive integer dimension n, which are called Euclidean n-spaces when one wants to specify their dimension.
- For n equal to one or two, they are commonly called respectively Euclidean lines and Euclidean planes.
- The qualifier "Euclidean" is used to distinguish Euclidean spaces from other spaces that were later considered in physics and modern mathematics.
Why it is Uncommon
Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Euclidean space article was read about 160,000 times in a year. ATK comes from the length of the article and DEF from its quality, so this card hits with 75 and blocks with 58: each hit it takes is cut by 23 %.
How to get Euclidean space
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.
