Welcome to the 250th Synthetic Daisies post! This post consists of three subthemes cross-posted from Tumbld Thoughts. The first is in honor of the Google Doodle for the 40th Anniversary of the Rubik's Cube, while the latter two are the supplemental readings for the tenth and eleventh episodes of the Cosmos reboot.
I. Rubik's 3-D CSS Cubes
Today is the 40th anniversary of the Rubik's Cube. Aside from an invention that sold 350 million copies, Rubik's Cube is also an example of a permutation puzzle that contains an interesting problem related to group theory. The doodle itself is unique in that it utilizes a technology called CSS 3-D transforms . Naturally, there is a Google Doodle.
