The Lemniscate

Yes, the Lemniscate. Currently, I am taking an algebra class. 38 years old and I find myself 22 years later relearning algebra. God help me... Anyway, I have learned that when writing a solution set in interval notation one will use this illustrious,geometrical and mathematical symbol to represent infinity. Instead of concentrating on solution sets and inequalities, I found myself thinking about the Tarot cards that clearly highlight this symbol -The Magician, Strength and the Two of Pentacles. Perhaps lack of focus on math is an indication as to why I didn't learn algebra as a teen? So, here I am posting about this "circle that turns round upon itself" http://www.youtube.com/watch?v=Jeq5a8bBh8c. It represents the energy that cannot be broken or destroyed, created or manipulated. It depicts that which has no end. This symbol portrays the endless force that is forever existant, divine and that which expresses itself through our thoughts and actions.
