The facts on the card
The card carries these facts from its Wikipedia article.
- He described the class of MHD waves now known as Alfvén waves.
- He was originally trained as an electrical power engineer and later moved to research and teaching in the fields of plasma physics and electrical engineering.
- Alfvén made many contributions to plasma physics, including theories describing the behavior of aurorae, the Van Allen radiation belts, the effect of magnetic storms on the Earth's magnetic field, the terrestrial magnetosphere, and the dynamics of plasmas in the Milky Way galaxy.
Why it is Uncommon
Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Hannes Alfvén article was read about 18,000 times in a year. ATK comes from the length of the article and DEF from its quality, so this card hits with 69 and blocks with 50: each hit it takes is cut by 20 %.
