In which decade?
The effect is named after the British physicist Brian Josephson, who predicted in ____ the mathematical relationships for the current and voltage across the weak link.
Answer
1960s. The effect is named after the British physicist Brian Josephson, who predicted in 1962 the mathematical relationships for the current and voltage across the weak link. From the Josephson effect article on Wikipedia.
Which of these cards hits hardest (highest ATK)?
Answer
Exterior algebra. Exterior algebra 82 · Higgs mechanism 78 · Josephson effect 74 · Warren Spahn 71 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 effect is named after the British physicist Brian Josephson, who predicted in 1962 the mathematical relationships for the current and voltage across the weak link.
- It is an example of a macroscopic quantum phenomenon, where the effects of quantum mechanics are observable at ordinary, rather than atomic, scale.
- The Josephson effect has many practical applications because it exhibits a precise relationship between different physical measures, such as voltage and frequency, facilitating highly accurate measurements.
Why it is Uncommon
Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Josephson effect article was read about 91,000 times in a year. ATK comes from the length of the article and DEF from its quality, so this card hits with 74 and blocks with 74: each hit it takes is cut by 30 %.
How to get Josephson effect
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.
