Galileo Drops the Ball - Virtual Experiment In around 1590 Galileo Galilei (1564-1642) climbed up the Leaning Tower of Pisa and dropped some balls to the ground. Two balls of different masses, but of similar shape and density that were released together hit the ground at the same time. Until then it was commonly believed that heavy things fall faster than light things. Many people still believe this, and casual observation of everyday phenomena often does tend to confirm this view. If you drop a brick and a feather at the same time the brick will probably hit the ground first. award entry - androp Bell This is an interactive music video game for the song "Bell" by the Japanese band "androp". “Bell” sings about expressing emotions and difficulty in communications. As we listened to this upbeat track, some keywords such as ‘words’ ‘future’ ‘run’ stood out from the lyrics. These words led us to think of a visual experience around the theme of ‘delivering a message’. These days, communications are established so easily using technologies such as mobile phone, email, Twitter, etc. But is there something that’s getting lost in this rapid & speedy communication?
Russia meteor virtually impossible to see coming Scientists have begun piecing together the characteristics of the meteor that exploded over Russia on the morning of February 15, using data from seismic instruments that track earthquakes and microphones designed to detect sonic booms from nuclear explosions. Unlike the asteroid DA14, which narrowly but predictably missed Earth later that day, the meteor was too small to detect before its contrail appeared in the dawn skies over the Russian city of Chelyabinsk. Yet even an object too small to detect can produce an impressive amount of destruction. The meteor was 15 meters across (compared with 50 meters for 2012 DA14) and weighed more than 7,000 metric tons when it entered Earth’s atmosphere, says Margaret Campbell-Brown, an astronomer at Western University in London, Ontario. Coincidentally, the largest observed meteor to enter the atmosphere since 1908 arrived just hours before a much larger object passed the planet uneventfully at a distance of about 27,000 kilometers.

A Beginner's Guide to Go Go is a two-player, abstract, "perfect information" strategy game in which players take turns placing white and black stones on a square grid.
