The facts on the card
The card carries these facts from its Wikipedia article.
- The law is named after 17th-century British physicist Robert Hooke.
- He first stated the law in 1676 as a Latin anagram.
- He published the solution of his anagram in 1678 as: ut tensio, sic vis.
Why it is Rare
Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Hooke's law 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 78 and blocks with 62: each hit it takes is cut by 25 %.
