George Ferris is the subject of Valentine’s Day Google doodle. Ferris is famous for inventing the Ferris wheel that features prominently in the animated doodle.
In 1891, the directors of the World’s Columbian Exposition issued a challenge to American engineers to build of a monument for the fair that would surpass the Eiffel Tower, the great structure of the Paris International Exposition of 1889. The planners wanted something “original, daring and unique.”
Ferris responded with a proposed wheel from which visitors could view the entire exhibition. He called it a wheel that would “Out-Eiffel Eiffel.”
Since 2006, we’ve had textured 3D buildings in Google Earth, and we’re excited to announce that we’ll begin adding 3D models to entire metropolitan areas to Google Earth on mobile devices in the near future.
Thanks to new imagery rendering techniques and computer vision, we’re able to create 3D cityscapes, complete with buildings, terrain and even landscaping, from 45-degree aerial imagery.
By the end of the year, we aim to have 3D coverage for metropolitan areas with a combined population of 300 million people.
Over the weekend, an amazing stat was bandied about by various tech sites: More than 97% of social photo-sharing site Pinterest’s Facebook fans are women. While plenty of the site’s 10.4 million registered users are men, its key demographic is women between the ages of 18 and 34.
Summary: Increasing numbers of studies of social networks point to much smaller numbers of real and active users — sharply reducing the value of Facebook, Twitter, Google, and many other sites preparing an initial public offering. http://bit.ly/wpf3Mf
