Rotor machine From Wikipedia‚ the free encyclopedia (Redirected from Rotor machines) Jump to: navigation‚ search A series of three rotors from an Enigma machine‚ used by Germany during World War II In cryptography‚ a rotor machine is an electro-mechanical device used for encrypting and decrypting secret messages. Rotor machines were the cryptographic state-of-the-art for a brief but prominent period of history; they were in widespread use in the 1930s–1950s. The most famous example is

We ask ourselves everyday if our life has meaning. We view our lives and others’ lives in different ways. I agree with life being viewed as a game‚ and life as learning is adding meaning to our life. I disagree with life having no meaning at all. Every human being views life differently and believes your life is influenced by different ideas and lessons. Life as a game creates a theory that we can’t just take our lives too seriously or else we won’t be happy and feel as if we have fulfilled

Wayback Machine: AOL.com circa 1997 The World Wide Web is a powerfully fluid and dynamic network of information‚ accessed over the medium of the Internet‚ that was popularized in the mid-nineties. Revolutionizing the way people can learn‚ entertain‚ communicate‚ and share‚ the World Wide Web is responsible for the ease that we have grown so accustomed to within our lives.

“Darwin among the Machines‚” 46 years before Forster (whose story‚ “The Machine Stops‚” was published 107 years ago). It is hard to believe that two stories with a similar tone could have been written so long ago. What is even more incredible is that they both seem to relate to present day society. How could two people (both from a time when technology was in its infancy) could write stories that could have been written about our time or even in our near future? The concept that machines will surpass
