Description:
The legendary Renaissance math duel that ushered in the modern age of algebra
The Secret Formula tells the story of two Renaissance mathematicians whose jealousies, intrigues, and contentious debates led to the discovery of a formula for the solution of the cubic equation. Niccolo Tartaglia was a talented and ambitious teacher who possessed a secret formula-the key to unlocking a seemingly unsolvable, two-thousand-year-old mathematical problem. He wrote it down in the form of a poem to prevent other mathematicians from stealing it. Gerolamo Cardano was a physician, gifted scholar, and notorious gambler who would not hesitate to use flattery and even trickery to learn Tartaglia's secret.
Set against the backdrop of sixteenth-century Italy, The Secret Formula provides new and compelling insights into the peculiarities of Renaissance mathematics while bringing a turbulent and culturally vibrant age to life. It was an era when mathematicians challenged each other in intellectual duels held outdoors before enthusiastic crowds. Success not only enhanced the winner's reputation, but could result in prize money and professional acclaim. After hearing of Tartaglia's spectacular victory in one such contest in Venice, Cardano invited him to Milan, determined to obtain his secret by whatever means necessary. Cardano's intrigues paid off. In 1545, he was the first to publish a general solution of the cubic equation. Tartaglia, eager to take his revenge by establishing his superiority as the most brilliant mathematician of the age, challenged Cardano to the ultimate mathematical duel.
A lively and compelling account of genius, betrayal, and all

Great product: thick and cozy
Size: Single Pelt/2 ft x 3 ft, Color: Natural (Ivory Whiite)
This is a lovely, thick sheepskin. I’m using it to drape over a chair. It’s very soft. The color is a natural white. Arrived quickly. The price was great for such a wonderful sheepskin.

Love it!
Size: 2' x 6' (Double Pelt), Color: Linen, Size: 2' x 6' (Double Pelt), Color: Linen
Exceeded all expectations. Bigger than I imagined it would be, super soft and thick, beautiful color (Linen), and no funky smell at all. It seems very durable. After running my hands all over it, no shedding occurred. I have yet to sit on it myself, though, as my cat claimed it right away - didn't even wait for me to remove the tag! He's been there for hours and I'm thinking I've lost my snuggle buddy, so I bought two more in the smaller size so he can have his own on the bed with me at night. I am so amazed by the quality, feel, and color. I can't believe I almost let other reviews deter me from this purchase. 100% thrilled with this beautiful pelt. Absolutely recommend!
UPDATE:
I received the other 2 purchased. Just as soft, just as thick, consistent color (Linen), no shedding, no smell. They have been in use for several days now without any issues. Love them all - and my snuggle buddy is back! 🥰

It’s wonderful!!
Size: 2' x 3' (Single Pelt), Color: Brown, Size: 2' x 3' (Single Pelt), Color: Brown
The product is wonderful! You know it is real, coz the smell doesn’t go away. I use it to meditate and cannot how nicely it created the perfect comforting barrier to help elevate my experience. I however want to find alternatives coz I stopped using animal products after turning a vegetarian. The size (it is bigger in person than in the pic) and color(brown) are perfect for what I do and doesn’t need much/any maintenance!
The white however needs a lot of attention and care.I’m sure it would last a decade and the weight is just right too!

Size: Single Pelt/2 ft x 3 ft, Color: Grey
I just got this today, 2 day delivery. It's a beautiful silver grey 2'x3', no smell, no shedding, super soft and has a luxurious feel. I can't believe it's real and so affordable! I have it draped on an ottoman in front of the couch. I love it and already want to buy a few more for my mid century modern couch and chairs. So chic! Highly recommend!
