Copernicus' Secret: How the Scientific Revolution BeganNicolaus Copernicus gave the world perhaps the most important scientific insight of the modern age, the theory that the earth and the other planets revolve around the sun. He was also the first to proclaim that the earth rotates on its axis once every twenty four hours. His theory was truly radical: during his lifetime nearly everyone believed that a perfectly still earth rested in the middle of the cosmos, where all the heavenly bodies revolved
Nicolaus Copernicus gave the world perhaps the most important scientific insight of the modern age, the theory that the earth and the other planets revolve around the sun. He was also the first to proclaim that the earth rotates on its axis once every twenty-four hours. His theory was truly radical: during his lifetime nearly everyone believed that a perfectly still earth rested in the middle of the cosmos, where all the heavenly bodies revolved around it. One of the transcendent geniuses of the early Renaissance, Copernicus was also a flawed and conflicted person. A cleric who lived during the tumultuous years of the early Reformation, he may have been sympathetic to the teachings of the Lutherans. Although he had taken a vow of celibacy, he kept at least one mistress. Supremely confident intellectually, he hesitated to disseminate his work among other scholars. It fact, he kept his astronomical work a secret, revealing it to only a few intimates, and the manuscript containing his revolutionary theory, which he refined for at least twenty years, remained hidden among my things. It is unlikely that Copernicus' masterwork would ever have been published if not for a young mathematics professor named Georg Joachim Rheticus. He had heard of Copernicus' ideas, and with his imagination on fire he journeyed hundreds of miles to a land where, as a Lutheran, he was forbidden to travel. Rheticus' meeting with Copernicus in a small cathedral town in northern Poland proved to be one of the most important encounters in history. Copernicus' Secret recreates the life and world of the scientific genius whose work revolutionized astronomy and altered our understanding of our place in the world. It tells the surprising, little-known story behind the dawn of the scientific age.Binding Type: Paperback

Dog Loves this toy!
Color: Crab
Keeps our poodle entertained and excited. The rechargeable battery lasts a long time. You can make it play crazy music or just shake. It’s hilarious to watch him play with it. It’s very chew resistant, and believe me, he tries his best to destroy it.
If you have a high energy dog, they’re gonna love it.

Great toy for puppies!
Color: Turtle
I love this turtle. My toy poodle puppy has boundless energy. She loves this thing. It keeps her busy so I can get laundry and other things done. I am buying a second one for when the first one loses its charge😂

It broke within the week
Color: Turtle
The toy was ADORABLE, it worked very well for the first week. And then it broke. I bought two for my puppy and my 8 year old shih tzus. It stopped vibrating and just made loud grinding and squeaking noises. I would recommend this toy if it lasted longer.

Offers tons of activity
Color: Turtle
My 70lb dog LOVES this turtle toy, was worth the price. He will play and play until he’s exhausted. We have to give him breaks from it. We use the second setting which is just for movement, no music. The only aspect I don’t like is that he will inadvertently press the button when he’s biting the toy, changing the setting and sometimes has turned it off. The velcro is super strong, which is good but makes it difficult to open. Battery life is decent, lasted a few days with him playing with it an hour or so each evening. I like the auto shut off after 30 minutes of no movement.
