  • TED Theme: Words About Words

    Language is the stuff of thought -- the more we know about it, the better we will understand ourselves. These speakers are trying to crack the mystery. Linguist Steven Pinker inspects the structure of sentences -- and discovers insight into human nature. Susan Savage-Rumbaugh finds a key to human language in the behavior of bonobo apes -- just as paleoanthropologist Zeresenay Alemseged shows us a set of 3.3-million-year-old hominid fossils that offer clues to the origins of speech. Erin McKean, meanwhile, gleefully collects and catalogs the products of modern wordmakers into a dictionary without limits.

  • APCS Java

    OOP Java for the AP CompSci A Test Starting Code: import java.util.Scanner; /** * Simple Polyalphabetic Cryptography * * @Chris Thiel * @28 Feb 2009 */ public class VignereCipherStartingCode { private static final String alphabet="ABCDEFGHIJKLMNOPQRSTUVWXYZ"; private static int nextChar(String k, int i){ i=i%k.length(); String letter=k.substring(i,i+1); return alphabet.indexOf(letter); } public static String encode (String m, String k){ String result=""; for (int i=0; i<m.length(); i++){ int offset=nextChar(k, i); String letter = m.substring(i,i+1); int newLetterIndex= alphabet.indexOf(letter)+offset; newLetterIndex=newLetterIndex % 26; result+=alphabet.substring( newLetterIndex, newLetterIndex+1); } return result; } public static String decode (String m, String k){ String result=""; return result; } public static void main(String[] args) { Scanner kb=new Scanner(System.in); System.out.print("Type a key: "); String key=kb.nextLine(); key=key.toUpperCase(); key=key.replace(" ","");//omit spaces System.out.print("Type a message: "); String message=kb.nextLine(); message=message.toUpperCase(); message=message.replace(" ",""); System.out.println("Using the key \""+key+"\" on \""+message+"\":"); String codedMessage=encode(message,key); System.out.println("Coded="+codedMessage); System.out.println("Decoded="+decode(codedMessage,key)); } } * 8 points: Complete the decode method so it can decipher the Vignere Cipher * 9 points: Adapt this so it can do a Progressive Polyalphabetic Cipher rather than a key * 10 points: Adapt the CarTalk Employee Applet's graphic user interface so that you can type a message in one text area, press a button and it shows the encoded text (using the Progressive Cipher), press another button and it shows the decoded text. * 11 points: Add a "key field" to the Applet, and use the Vignere Cipher, working in a similiar fashion as the 10 point version

  • Our Changing Planet

    Our Changing Planet is an informative public television series about climate and environmental change, and opportunities to preserve Earth's life-sustaining natural resources for future generations. See visible, life-altering changes taking place globally as Earth's climate warms, from animal extinctions, to vanishing glaciers, to melting polar ice sheets and permafrost, to rising seas that threaten coastal communities and low lying islands. Learn about environmental damage from the corrosive effects of acid rain; the hole in ozone layer that allows harmful ultraviolet radiation to reach Earth's surface; extreme weather events like hurricanes, heat waves, cold snaps, and droughts; the use of fossil fuels and the build-up of greenhouse gases in our atmosphere; alternative energy sources such as wind and solar power to reduce our dependence on coal and oil; and space-age technology that helps farmers grow crops in a more Earth-friendly way. What effect does a growing world population and expanding economy have on Earth's resources? What are the hidden environmental costs behind the everyday products we simply throw away? Will we exhaust Earth's freshwater resources? How do plant and animal species respond to human transformation of the land and rivers for housing, industry, transportation, farming, ranching, mining and forestry? All episodes are written and produced at UMAC, the Upper Midwest Aerospace Consortium at the University of North Dakota. Full episodes, complete with closed captioning and supporting links and information are available at www.umac.org/ocp. About one third of the 6,000 amphibian species known to exist on Earth are threatened with extinction. What is the message these sensitive creatures are dying to send about the health of our planet?
