Harry Potter




Harry Potter is a series of seven fantasy novels written by British author J. K. Rowling which has also spawned films, video games and Potter-themed merchandise. The books chronicle the adventures of the eponymous adolescent wizard Harry Potter, together with Ron Weasley and Hermione Granger, his best friends from the Hogwarts School of Witchcraft and Wizardry. The central story arc concerns Harry's struggle against the evil wizard Lord Voldemort, who killed Harry's parents in his quest to conquer the Wizarding world, after which he seeks to subjugate the Muggle (non-magical population) world to his rule.

Since the release of the first novel Harry Potter and the Philosopher's Stone in 1997, which was retitled Harry Potter and the Sorcerer's Stone in the United States, the books have gained immense popularity, critical acclaim and commercial success worldwide.[2] As of June 2008, the book series has sold more than 400 million copies,[3] has been translated into 67 languages[4] and the last four books have consecutively set records as the fastest-selling books in history.[5][6][7]The seventh and last book in the series, Harry Potter and the Deathly Hallows, was released on July 21, 2007.[8] Publishers announced a record-breaking 12 million copies for the first print run in the United States alone.[9]

The success of the novels has made Rowling the highest-earning novelist in history.[10] English language versions of the books are published by Bloomsbury in the United Kingdom, Scholastic Press in the United States, Allen & Unwin in Australia, and Raincoast Books in Canada. Thus far, the first five books have been made into a series of motion pictures by Warner Bros. The sixth, Harry Potter and the Half-Blood Prince, is scheduled for release on July 17, 2009.[11] The series also originated much tie-in merchandise, making the Harry Potter brand worth £7 billion ($15 billion).[12]

The Da Vinci Code




The Da Vinci Code is a controversial mystery/detective novel by US author Dan Brown, published in 2003 by Doubleday. It follows symbologist Robert Langdon as he investigates a murder in the Louvre, and discovers a battle between the Priory of Sion and Opus Dei over the possibility of Jesus having been married to and fathering children with Mary Magdalene.

This novel has provoked a popular interest in speculation concerning the Holy Grail legend and the role of Mary Magdalene in the history of Christianity. The novel has been extensively criticized by Catholics and other Christians as a dishonest attack on the Church. It has also been criticized for historical inaccuracy.

Dan Brown's novel was a major success in 2004 and at times it was outsold only by the highly popular Harry Potter series.[1] It spawned a number of offspring books and drew glowing reviews from the New York Times, People Magazine and the Washington Post.[2] It also re-ignited interest in the history of the Roman Catholic Church. Additionally, The Da Vinci Code, itself preceded by other Grail books such as The Holy Blood and the Holy Grail by Michael Baigent and others, and Umberto Eco's Foucault's Pendulum, has inspired a number of novels very similar to it, including Raymond Khoury's The Last Templar, and The Templar Legacy by Steve Berry.

It is a worldwide bestseller which had 60.5 million copies in print by May 2006 and has been translated into 44 languages. It is thought to be the 19th best-selling book of all time. Combining the detective, thriller and conspiracy fiction genres, the book is the second book by Dan Brown to include the character Robert Langdon, the first being his 2000 novel Angels and Demons. In November 2004 Random House published a "Special Illustrated Edition" with 160 illustrations.

In 2006, a film adaptation, The Da Vinci Code, was released by Columbia Pictures.

Ten Things You Can Do in Ten Minutes To Be a More Successful e-learning Professional

You need a break and, instead of heading to the coffee pot, what can you do in 10 minutes that will refresh and energize you and increase your job satisfaction and career success?

1. Find an e-learning conference to go to and send an email to your manager giving 10 reasons why this will help you perform better. If travel is a problem, find a local seminar to go to.
2. Find an e-learning conference to submit to. It is much better to go to a conference as a speaker and the process of figuring out what you want to talk about and writing an abstract will be a valuable reflection process.
3. Write a short description of what you learned at the last conference or seminar you went to or the last article or book you read and circulate it to your colleagues. They will appreciate it and it will reinforce what you learned. It might also help your chances of getting funding for your next conference (see 1).
4. Do a search on “e-learning”, “instructional design”, “online degrees”, or another topic related to your job and see what people find. Refine your search and try again. Maybe you’ll find something you want to look at, maybe not. If not, use the rest of your ten minutes and search on something totally different, like “swing dancing”, and see if you like the results better.
5. Write a note your manager with 10 reasons why you deserve a 10% salary increase. Don’t send it unless you came up with the reasons quickly. If you struggled with the list, rewrite it as the 10 things you need to do to deserve a 10% salary increase. Then act upon it.
6. Take an online course - or at least part of one- and think about how it is designed rather than the content. What are 10 things you would do to improve it? (What would colleagues say if it was your class they were going through?)
7. Read 10 current e-learning job descriptions and see how many you are qualified for. Write down 10 ideas for your own professional development just in case you ever want to go job hunting.
8. Email the e-learning expert you most admire and ask him or her to schedule a 10 minute phone call with you to discuss your three most important questions about e-learning. Write up what you learn (when you have the call) and circulate it to your colleagues (see 3). Also, make sure you introduce yourself to that person at your next conference (see 1).
9. Do a search on “learning technology trends” or “Web 2.0″ and identify at least one new technology you know little about that has the potential to improve what you do. Read one or two articles about it.
10. Ask a colleague the most exciting e-learning idea he or she has had or read about recently and discuss it why it is exciting. You can do this by phone or email, but over coffee is best. See, you get to go to the coffee pot after all!

Finally, think of your own idea for a 10 minute activity that can renew and improve your e-learning practice and post it as a comment to this article so others can benefit.

Thanks to Mark Notess for suggestions 7-9 and to CIO Magazine for inspiring the idea.
