The 13 Most Important Numbers in the Universe - James D. Stein's Cosmic Numbers In the 17th century, scientists understood three phases of matter—solids, liquids and gases (the discovery of plasma, the fourth phase of matter, lay centuries in the future). Back then, solids and liquids were much harder to work with than gases because changes in solids and liquids were difficult to measure with the equipment of the time. So many experimentalists played around with gases to try to deduce fundamental physical laws. Robert Boyle was perhaps the first great experimentalist, and was responsible for what we now consider to be the essence of experimentation: vary one or more parameter, and see how other parameters change in response. Boyle discovered the relationship between the pressure and volume of a gas, and a century later, the French scientists Jacques Charles and Joseph Gay-Lussac discovered the relationship between volume and temperature.

Marketing for Libraries What do people want and need from a library? What services can your library provide? How can services be connected with the needs of current and potential library users? Marketing is much more than creating attractive displays and updating your Facebook page, it's about meeting the needs of individuals and groups. Marketing is about understanding the needs and interests of current and potential users, reaching those individuals with quality resources and services, and evaluating the experience so adjustments can be made to increase effectiveness, efficiency, and appeal.

The History of Encryption The History of Encryption 700 BC Scytale The Spartan military used scytales to send sensitive missives during times of battle. Both sender and recipient had a wooden rod of the exact diameter and length. To encrypt a message, the sender tightly wound a piece of leather or parchment around the stick and wrote a message on it. The unwound leather was sent to the recipient, who could only read a message once it was tightly wound around his own scytale. 1467 Alberti cipher Leon Battista Alberti invented and published the first polyalphabetic substitution cipher, changing the course of encryption forever. 1797 Jefferson wheel Invented by Thomas Jefferson while he was George Washington's secretary of state, the wheel consisted of 26 cylindrical wooden pieces threaded onto an iron spindle. 1943 Enigma machine 1961 First computer password Developed by MIT's CTSS (Compatible Time-Sharing System), when computer time was scarce, extremely expensive and limited to research institutions. 1995 "Hackers"

Tech Literacy II: Skills for the Online Instructor "Technology is just a tool. In terms of getting the kids working together and motivating them, the teacher is the most important." — Bill Gates Maybe you have been tapped to offer a popular course via the Internet, or you are looking to take advantage of the growing opportunities available to expand your professional portfolio.
