The facts on the card
The card carries these facts from its Wikipedia article.
- If a long and heavy pendulum suspended from the high roof above a circular area is monitored over an extended period of time, its plane of oscillation appears to change spontaneously as the Earth makes its 24-hourly rotation.
- This effect is greatest at the poles and diminishes with lower latitude until it no longer exists at Earth's equator.
- Foucault introduced his pendulum in 1851 in the first experiment to give simple, direct evidence of the Earth's rotation, which he further demonstrated in 1852 with a gyroscope experiment.
Why it is Uncommon
Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Foucault pendulum article was read about 190,000 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 68: each hit it takes is cut by 27 %.
