Morse code Chart of the Morse code letters and numerals. Morse code is a method of transmitting text information as a series of on-off tones, lights, or clicks that can be directly understood by a skilled listener or observer without special equipment. The International Morse Code encodes the ISO basic Latin alphabet, some extra Latin letters, the Arabic numerals and a small set of punctuation and procedural signals as standardized sequences of short and long signals called "dots" and "dashes", or "dits" and "dahs". Because many non-English natural languages use more than the 26 Roman letters, extensions to the Morse alphabet exist for those languages.

How to Use Wolfram Alpha Inside Google Docs Wolfram Alpha is a search engine that is probably best know for helping students solve mathematics problems. But there is more to Wolfram Alpha than just computational data. Wolfram Alpha can help students quickly locate information about famous people in history, locate socioeconomic data, find science data, and even help students find information about music theory. Unlike on Google or Bing, when students search on Wolfram Alpha they won't be shown a list of links. When students search Wolfram Alpha they will be shown organized collections of information. That is why Wolfram Alpha and Google searches can complement each other.
