He published the solutions to the cubic and quartic equations in his 1545 book Ars Magna. The solution to one particular case of the cubic equation (in modern notation), was communicated to him by Niccolò Fontana Tartaglia, and the quartic was solved by Cardano's student Lodovico Ferrari. In his exposition, he acknowledged the existence of what are now called imaginary numbers, although he did not understand their properties (described for the first time by his Italian contemporary Rafael Bombelli, although mathematical field theory was developed centuries later).A Manicka Praveenhttps://www.blogger.com/profile/07084472643729671593noreply@blogger.comtag:blogger.com,1999:blog-5299536661063439027.post-79732148476029337662013-01-08T06:02:05.152-08:002013-01-08T06:02:05.152-08:00Cardano argued that the deaf should be taught to w...Cardano argued that the deaf should be taught to write and could do that before learning how to speak.

He is renowned for his invention of the combination lock and the Cardan shaft. The Cardan shaft is a universal joint connecting the gear box to the rear axle of a rear wheel drive. He also correctly identified the cause of illness for the Archbishop of Scotland (feather pillows). Due to his wife contracting syphillis, he wrote one of the earliest medical treatises on this diseases. He also solved a mathematical unknown during that time, known as the cubic equations. In doing so, he contributed greatly to Algebra.<br /><br />http://www.uh.edu/engines/epi1950.htmPoon Wai Kit (潘维杰 19）https://www.blogger.com/profile/12522337251843071866noreply@blogger.comtag:blogger.com,1999:blog-5299536661063439027.post-31443282270978078262013-01-07T04:59:53.651-08:002013-01-07T04:59:53.651-08:00 Cardano was an inventor, an astrologer, a philoso...

The diplomat Thomas Randolph recorded the "merry tales" rumoured about his methods still current in Edinburgh nine years later.[3] Cardano himself wrote that the Archbishop had been short of breath for ten years, and after the cure was effected by his assistant, he was paid 1,400 gold crowns.(Wikipedia)<br />He also played an important role in the development of algebra.He also invented the Cardono's Rings. Cardano invented several mechanical devices including the combination lock, the gimbal consisting of three concentric rings allowing a supported compass or gyroscope to rotate freely, and the Cardan shaft with universal joints, which allows the transmission of rotary motion at various angles and is used in vehicles to this day. He studied hypocycloids, published in de proportionibus 1570. The generating circles of these hypocycloids were later named Cardano circles or cardanic circles and were used for the construction of the first high-speed printing presses. For all he has done maths played a great part in them.ANBARASAN SUBRAMANIYANhttps://www.blogger.com/profile/08983280916608975708noreply@blogger.com
