What is Wolfram Alpha? It is a supercomputing brain. It provides calculates and provides comprehensive answers to most any science or math question. Unlike other search sources, you and your students can ask questions in plain language or various forms of abbreviated notation. Contrary to popular belief, Wolfram Alpha is not a search engine. Unlike popular search engines, which simply retrieve documents based on keyword searches, Wolfram computes answers based on known models of human knowledge. It provides answers which are complete with data and algorithms, representing real-world knowledge.

Keyboard accelerators, mnemonics, and shortcuts Keyboard accelerators let you open menus using special keyboard shortcuts. The table lists shortcuts for people using Chrome on Windows/Linux. If you're working in Internet Explorer or Firefox, replace Alt with Alt+Shift. If you're working on a Mac, replace Alt with Ctrl+Option.

A list of keyboard shortcuts for Google documents. If you're looking for keyboard shortcuts for comments and discussions in Google documents, you can visit the comments and discussions guide.  If you use a Mac, you can use the shortcuts below by replacing Ctrl with Command key (or 'Apple' key), and Alt with the option key.

Have you ever wanted to create short "how to" video for your students to use for homework, remembering facts, and solving math problems. How often have your students stated, "I could not complete the homework assignment, because I could not remember the steps and no one could help me." Well the answer is to create a screencast or video for posting on your class wiki or blog for students to view at home or anywhere else they have web access.

I met with a representative from Turning Technologies today. While many of you may have had the opportunity to use interactive response systems (so-called "clickers"), we're finally moving into the 21st century; now that we have reasonable computing facilities at all of our schools, our goal is to fully utilize them and add interactivity. Thus, these interactive response systems that allow students to answer questions and take surveys in class with their aggregated responses displayed within a PowerPoint presentation or on a standalone unit. The real beauty of Turning's system is its direct integration with PowerPoint (sorry, no OpenOffice integration, although the software can be superimposed over any Mac or Windows software). It includes a dedicated toolbar and a series of macros for automating the creation of interactive slides.

Need to show something to someone? iShowU is your answer! iShowU is designed to record anything on your screen, instantly - both audio, and video! If a picture is worth a thousand words, then a movie is worth a million. Imagine the time you'll save writing Grandma an email about how to magnify her dock when you can just shoot a movie in seconds.

Say you're an investor and you want to see how two companies are faring against each other on the market. You could type in "IBM versus Apple" and Wolfram|Alpha will generate graphs and tables to compare the stocks over time. It also give you the Web-based sources used to generate the data, so you know where the numbers are coming from. The site also solves equations and shows the steps it took to do so, which will be of interest to high school students and math majors. Not into number crunching? If you live near the coast, you could type in "tides in ____" and find charts of tidal and lunar information. You could also graph that against other cities, which would be cool if you're a surfer. The site is also interesting for academic queries. Type in "Internet users in Africa" and you'll get the total number of Web users there - 51 million - as well as lists of the number of users by country plus graphs of this information. If you're in the fisheries business, or if you're an environmentalist, you could type in "fish produced in Italy versus France" to get an idea of how that sector is faring. The answer includes specifics, like how much of the fish crop was farmed versus what was captured. Such data could be used to argue policy points or to debate whether or not certain industries are sustainable.

You enter your question or calculation, and Wolfram|Alpha uses its built-in algorithms and growing collection of data to compute the answer. Based on a new kind of knowledge-based computing
