Differentiable manifold quiz: 3 questions
Three questions on the Differentiable manifold card, the way WikiCards duels ask them. Pick an answer, the facts are just below.
Find the missing word
Any manifold can be described by a ______ of charts.
Answer
collection. Any manifold can be described by a collection of charts. From the Differentiable manifold article on Wikipedia.
Which of these cards hits hardest (highest ATK)?
Answer
Differentiable manifold. Differentiable manifold 80 · Lock and key 71 · Inflight smoking 68 · Beehive Cluster 64 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.
- Any manifold can be described by a collection of charts.
- One may then apply ideas from calculus while working within the individual charts, since each chart lies within a vector space to which the usual rules of calculus apply.
- If the charts are suitably compatible, then computations done in one chart are valid in any other differentiable chart.
Why it is Uncommon
Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Differentiable manifold article was read about 65,000 times in a year. ATK comes from the length of the article and DEF from its quality, so this card hits with 80 and blocks with 49: each hit it takes is cut by 20 %.
How to get Differentiable manifold
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.
