Dozen Questions About Fibonacci Numbers
2, 3, 5, 8, who do we appreciate? Fibonacci! Fibonacci! Fibonacci! Your dozenal correspondent views Fibonacci numbers as classic square-domino tilings, honeycomb walks, ordered partitions, restricted permutations, and more. Come explore this fascinating number sequence.
Causing Bipolar Orientation Reversal of Appendage Motion
"While sitting are your desk, lift your right foot off the floor, and make clockwise circles. Now while doing this, draw the number "6" in the air with your right hand. Your foot will change direction and there's nothing you can do about it." ---Widely distributed e-mail.
This mathematical exploration will quite literally have you spinning in circles. An integer is bipolar if its air depiction causes a rotating foot to switch direction (regardless of the direction of rotation). So which integers are bipolar?
in Two, Two in One: Mathematics and the Arts
Carla Farsi & Doug Craft
Mathematics and art are related endeavors. What mathematician has not marveled at the beauty of an elegant proof and what serious artist has not been aware of the importance of form and composition to a successful art work? This article discusses the similarities and differences between these two endeavors, while celebrating successful collaborations of Denver area mathematicians and artists.
Conversation with Leonardo Pisano
A Math Horizon's exclusive interview with Leonardo Pisano, AKA Fibonacci. Learn why he introduced the west to "Indian figures", "zephir", and "al-jabr" in his book Liber Abaci. Hear his account of an imperial contest. And heed his excellent advice for current students of mathematics.
Mathematician's Look at Foucault's Pendulum
Strip away the physics and Foucault's Pendulum is nothing more than a calculus problem posed on a sphere. Since some of Einstein's work equates the mathematical quantity, curvature, with the physical quantity, matter, it makes sense to tackle the familiar pendulum problem from a completely mathematical formulation.
