This cornerstone in the history of mathematics first appeared in 1545 as Artis magnae, sive de regulis algebraicis. A primer on "the great art" of algebra, it contains the first revelation of the principles for solving cubic and biquadratic equations, along with other innovations. Author Girolamo Cardano (1501-76) was famous not only for his prodigious gifts as a mathematician, but also for his skills as a physician, astrologer, and gambler. Cardano's novel approach to the treatment of scientific problems reflects the spirit of his era, the zenith of the Italian Renaissance.Long unavailable, except in rare Latin editions, Cardano's masterpiece is newly accessible in this excellent English translation by T. Richard Witmer. Adapted to modern mathematical syntax, it will appeal to both historians and mathematicians. Oystein Ore, a renowned mathematician and historian of science, provides an informative introduction, and the text is complemented by 26 black-and-white illustrations.

Perfect Visor
Size: One Size, Color: (001) Black / Black / Reflective
I bought this thinking I wouldn’t like it. I was so wrong. This is lightweight and the perfect fit. What a great value. It’s so comfortable on your head and the vent on it was a great idea. Adjusts easily and just a great buy.

A great sport visor
Size: One Size, Color: (100) White / White / Reflective
My head is small so a lot of visors don’t fit because of the Velcro. This is perfect and the ability to wet it for coolness is great. Love it for tennis.

Great for running
Size: One Size, Color: (001) Black / Black / Reflective
Hat fits well and worked great for my marathon. The Velcro doesn’t pull on my hair.

Cute and comfortable, though a little big without tightening a bit
Size: One Size, Color: (100) White / White / Reflective
Love the bright color and material. It fits a little big at first but has the ability to tighten quite a bit so it should be fine like it is for me. I just have a smaller head. It has great coverage. Feels comfortable as well.

Perfect fit
Size: One Size, Color: (001) Black / Black / Reflective
I ordered this to wear during my upcoming vacation. It will shade my face from direct sunlight. I initially wished the brim was just a tad bit shorter but then I realize the current brim size will serve the purpose; that being the reason why it was purchased.
