History and Women: Maria Anna Mozart Maria Anna Mozart (30 July 1751 – 29 October 1829) Musician Maria Anna Mozart, beloved nicknamed Nannerl, was the elder and only sister of Wolfgang Amadeus Mozart. As children, both were considered gifted musical prodigies and their father, Leopold, arranged tours to display their talents to the masses in the grandest capitals of Europe. They enjoyed a pleasant childhood, indulging their musical creativity and creating their own childish kingdom. Thereafter, Leopold focused all his attentions on Mozart, not Nannerl. Victoria, one of her students, becomes her protégé. Even her choice of suiters were one-by-one turned away by Leopold. Nannerl grew ever more distant from Wolfgang, especially after his marriage to Constanze Weber. When Wolfgang dies, Nannerl re-awakens to life and makes it her purpose to honor her brother by collecting and assembling all his compositions and erecting monuments to honor his life.

Automating Tinder with Eigenfaces While my friends were getting sucked into "swiping" all day on their phones with Tinder, I eventually got fed up and designed a piece of software that automates everything on Tinder. An update on Tinderbox: Well, I didn't think I'd do it. I even wrote in my post that I wouldn't. Nearly a year since I released Tinderbox, I finally decided to take a packaged approach and make the technology more available. I'd like to introduce Bernie A.I., a personified artificial intelligence that is the next evolution from this project. Since Tinder’s rising popularity, including its use by Olympic athletes such as snowboarder Rebecca Torr, Tinder has achieved critical adoption as a launchpoint for singles meeting singles. Dubbed "Tinderbox", the first version only took 3 weeks to build. Eigenface is a quick and easy algorithm to implement facial recognition without the use of complex software like OpenCV. And computing the distance is just as easy: What are the results so far?

Kepler's Discovery 19 Maps That Will Blow Your Mind and Change the Way You See the World. Top All-time. You Won’t Believe Your Eyes. Watch. Many lists of maps promise to change the way you see the world, but this one actually does. The maps above don’t count towards the 19, so your world view hasn’t changed yet. However, the binocular-like image represents your upcoming experience. You look around. Time to blow your mind. 1. Most maps focus on demographics, geological makeup, and natural phenomena such as temperature and wind. I give you exhibit number one. A whopping 38 percent of states end with the first letter in the alphabet, which amazes to no end. 2. In contrast, zero — I repeat, zero — states end with the last letter of the alphabet (i.e. The only viable solution is to change current state names to end with zed. 3. We raise similar issues when we look at letters at the beginning of state names. 4. Several mini-explosions are going off in your head at this very moment, so brace yourself for what comes next. The animated map above is only a snapshot of the millions of lives that the lines and shapes represent. 5. 6.

Babylonian Astronomers Used Geometry to Calculate Jupiter’s Position | Archaeology, Astronomy According to Prof. Mathieu Ossendrijver of Humboldt University in Germany, Babylonian astronomers used geometry to calculate the position of Jupiter — a technique historians of science previously believed humans had not developed until at least 1,400 years later. Left: BM 34757, one of the Babylonian cuneiform tablets translated by Prof. Prof. These tablets were unearthed in the 19th century near the temple Esagila in Babylon and are now on display in the Middle Eastern Department of the British Museum, London. According to Prof. The texts contain geometrical calculations based on a trapezoid’s area, and its ‘long’ and ‘short’ sides. The ancient astronomers also computed the time when Jupiter covers half of this 60-day distance by partitioning the trapezoid into two smaller ones of equal area. “The idea of computing a body’s displacement as an area in time-velocity space is usually traced back to 14th-century Europe,” said Prof. Mathieu Ossendrijver. 2016.
