Vector space quiz: 3 questions
Three questions on the Vector space card, the way WikiCards duels ask them. Pick an answer, the facts are just below.
Find the missing word
Scalars can also be, more generally, ______ of any field.
Answer
elements. Scalars can also be, more generally, elements of any field. From the Vector space article on Wikipedia.
Which of these cards hits hardest (highest ATK)?
Answer
Alexander Suvorov. Alexander Suvorov 94 · Vector space 84 · Positivism 81 · Slime mold 78 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.
- The operations of vector addition and scalar multiplication must satisfy certain requirements, called vector axioms.
- Real vector spaces and complex vector spaces are kinds of vector spaces based on different kinds of scalars: real numbers and complex numbers.
- Scalars can also be, more generally, elements of any field.
Why it is Rare
Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Vector space article was read about 220,000 times in a year. ATK comes from the length of the article and DEF from its quality, so this card hits with 84 and blocks with 88: each hit it takes is cut by 35 %.
How to get Vector 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.
