Method of moments quiz: 3 questions
Three questions on the Method of moments card, the way WikiCards duels ask them. Pick an answer, the facts are just below.
Find the missing word
This is done by using discrete meshes as in finite difference and finite element methods, often for the ______.
Answer
surface. This is done by using discrete meshes as in finite difference and finite element methods, often for the surface. From the Method of moments article on Wikipedia.
Which of these Wikipedia articles is read the most in a year?
Answer
George Buchanan. George Buchanan 18,000 · Integral fast reactor 11,000 · Method of moments 8,700 · Mary Lou Jepsen 6,600 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.
- It is used in computer programs that simulate the interaction of electromagnetic fields such as radio waves with matter, for example antenna simulation programs like NEC that calculate the radiation pattern of an antenna.
- Generally being a frequency-domain method, it involves the projection of an integral equation into a system of linear equations by the application of appropriate boundary conditions.
- This is done by using discrete meshes as in finite difference and finite element methods, often for the surface.
Why it is Common
Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Method of moments article was read about 8,700 times in a year. ATK comes from the length of the article and DEF from its quality, so this card hits with 72 and blocks with 74: each hit it takes is cut by 30 %.
How to get Method of moments
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.
