All numbers lead to one

04 Oct

Collatz graph

In 1937, mathematician Lothar Collatz proposed that given the following algorithm, you will always end at the number 1:

  1. Take any natural number, n.
  2. If n is even, divide it by 2.
  3. Otherwise, n is odd. Multiply it by 3 and add 1.
  4. Repeat indefinitely.

Developer Jason Davies puts it into reverse and shows all the numbers that fall within an orbit length of 18 or less. Press play, and watch the graph grow. Mostly a fun animation for nerds like me.

The Vizosphere

25 Jul

Vizosphere

There are lots of people on Twitter who talk visualization. Moritz Stefaner had some fun with Gephi for a view of a whole lot of those people. He calls it the Vizosphere.

This map shows 1645 twitter accounts related to the topic of information visualization. The accounts were determined as follows: For a subjective selection of "seed accounts", the twitter API was queried for followers and friends. In order to be included into the map, a user account needed to have at least 5 links (i.e. follow or being followed) to one of these a
ccounts. The size of the network nodes indicates the number of followers within this network.

Check out the high-res version in the player below.

All roads lead to philosophy, on Wikipedia

All Roads lead to Philosophy - xefer

Jeffrey Winter tests a hunch about links leading to philosophy on Wikipedia:

There was an idea floating around that continuously following the first link of any Wikipedia article will eventually lead to "Philosophy." This sounded like a reasonable assertion, one that makes a certain amount of sense in retrospect: any description of something will typically use more general terms. Following that idea will eventually lead… somewhere.

Winter's curiosity led to this simple mashup. Type in some terms in the search bar and see where those topics lead to. Lo and behold, they all reach philosophy somehow. The above was my own search for economy, poop, science, Forrest Gump, hamburger, and Chicago. Philosophy: the Kevin Bacon of Wikipedia.
