Presentation Zen has tons of pointers and plenty of helpful links. If you regularly have to do PowerPoints or think you may need to in the future, consider subscribing to their feed.
Also, check out these excellent presentation posts from Particle Tree and Michael Hyatt.

World Changing.com has been around for a while, and they describe their mission succinctly:
"WorldChanging.com works from a simple premise: that the tools, models and ideas for building a better future lie all around us. That plenty of people are working on tools for change, but the fields in which they work remain unconnected. That the motive, means and opportunity for profound positive change are already present. That another world is not just possible, it's here. We only need to put the pieces together."
Their blog is full of many interesting devices from Street light/solar power generators/wifi networking to waterless washing machines.
(2) The Watt
The Watt is an interesting forum on alternative energy. Their site also hosts an interesting weekly podcast.
Grist.org is one of the most popular environmental focused sites - sort of the Slate for environmental issues.
(4) Leicester city thermal imaging
Here is an interest site found my We Make Money Not Art. Leicester city council is using thermal imaging to target homeowners releasing excess heat and offer them free cavity and roof installation.
(5) PVC Greenhouse
An interesting blogspot site that shows you how to make a greenhouse using - you guessed it - PVC piping.
(6) Forests Forever
Last, but not least, here is a site full of great photos of forests around the world. The bad translations and apparent Fuji sponsorship leads me to believe that this came out of Japan. Definitely worth exploring, but only if you have a fast internet connection.
"Throughout most of 1942, the Navy kept trying to act smart by relying on technical know-how, and stubbornly refused to take operational lessons from the British. The Navy also lacked the organizational structure necessary to apply the technical knowledge it did have to the field. Only when the Navy set up the Tenth Fleet--a single unit to coördinate all anti-submarine warfare in the Atlantic--did the situation change. In the year and a half before the Tenth Fleet was formed, in May of 1943, the Navy sank thirty-six U-boats. In the six months afterward, it sank seventy-five. "The creation of the Tenth Fleet did not bring more talented individuals into the field of ASW"--anti-submarine warfare--"than had previous organizations," Cohen writes. "What Tenth Fleet did allow, by virtue of its organization and mandate, was for these individuals to become far more effective than previously." The talent myth assumes that people make organizations smart. More often than not, it's the other way around."
By the way, the link has the New Yorker print version available as a free pdf download. I found the article more readable in that format.

Suprglu just started and there are certainly a number of features missing. They definitely needs a search engine, and more templates options would be nice. Additionally, there can be a delay between the time I post here on Blogger and when the posts show-up on Suprglu. I wouldn't use Suprglu as a blog intended for an audience, but I will certainly refer to it in order to keep track of information I want to hold onto.
On a related note, there have been a lot of attempts recently to keep organize and link these useful sites. Check out diggdot.us and reddit.com. Trendalicio.us only keeps track of del.icio.us, but I update it regularly throughout the day to find tons of great links. Also, here is a useful library of tools for del.icio.us.

"Dreamlines is a non-linear, interactive visual experience. The user enters one or more words that define the subject of a dream he would like to dream. The system looks in the Web for images related to those words, and takes them as input to generate an ambiguous painting, in perpetual change, where elements fuse into one another, in a process analogous to memory and free association."
Enter a "dream" keyword and watch the effect. It is pretty cool.
Fortunately, there are a number of web-based applications that help you get around these limitations. Meebo certainly works towards negating the IM wars between AOL, Yahoo, MSN, and GMail/Jabber. Through the magic of AJAX, you can talk to anyone in any of these applications through a single internet window. And since you don't have to download and install any programs, it is very firewall friendly.
Meebo can also be set as an active-desktop. In other words, a Meebo session can replace your desktop image and you can IM your friends without opening a window.

“Welcome to a new year in Stanford’s ongoing rediscovery of the 19th century. In 2006, we will rerelease a collection of Arthur Conan Doyle’s tales of Sherlock Holmes, just as they were originally printed and illustrated in The Strand Magazine...Over 12 weeks from January through April 2006, Stanford will be republishing, free of charge, two early Holmes stories, “A Scandal in Bohemia” and “The Speckled Band”; the nine-part novel, The Hound of the Baskervilles; and the famous “last” encounter between Holmes and Moriarty, “The Final Problem”.”

I thought it might be a good time to round-up some of the many excellent sites that attempt to explain special relativity and his other scientific contributions:
PBS Nova Special with comments from experts
5-minute video on relativity
Relativity Theory in Words of Four Letters or Less
NYTimes: That Famous Equation and You by Brian Greene
Also, here are some other sites that are a more detailed, but worth looking at for those of you who are interested:
Physics Flash Animations (scroll down to relativity theory)
The University New South Wales: Einstein Light
SpaceTimeTravel: Relativity Visualized
Why Can't We Travel Faster Than Light?
How Stuff Works: Special Relativity
UCLA: Relativity (very detailed)
Living Reviews in Relativity
Einstein Archives Online
Update: See what it looks like to travel at the speed of light.
Update: Also check out the free Online TV Recorder, which gathers channels from around the world and provides personal Tivo-like saving function.
Update: Here is an index of the growing number of internet based "IPTV" shows.

Note: I am not 100% confident these materials should be freely available on this Ukrainian website that spells O´Reilly wrong in the URL. I will leave it up to you to either avoid the page or download the books quickly.
Update: Also check out the list of O'Reilly podcasts.
Update: Here is an even bigger collection.
Update: Here's another one. I think Diggers killed the site above, but I am leaving it there in case it comes back.
Update: Another library. Not O'Reilly, but quite good.
What does this mean for the scholar? Now you have an easy way to enlist your peers to help you review your projects. For example, let's say you have a writing group - each class member can log on to Writeboard and make their edits. Afterwards you can compare and accept the useful changes. Or what if you are working on group paper? Now you can easily track previous versions and edits.
Plus, you can't beat the price.

"Mark Bowden, national correspondent, the Atlantic - The Electric Kool-Aid Acid Test, which was not part of any course; in fact, I no longer recall how or why I picked it up, but to me it was incendiary. I was an English major, so I was reading a lot, but this was something entirely new and different. Here was a writer clearly having fun … no, the time of his life, with words, ideas, observation, storytelling. I was already interested in writing, but Wolfe made me crazy about writing. "
A couple of these look books look really interesting. I definitely want to pick-up Personal Knowledge and Fear of Flying.
Oh, and Mark Cuban apparently loved The Fountainhead. There's a shocker.
Update: Also check out this list of the Top 20 Geek Novels.
Edublogs is a great resource for education professionals and for those of us hunting for education resources. There are currently 1905 edublogs listed (check out their Frappr map to see where people are blogging from).

Currently, Connexions' content is a little lacking. As of this post, there are 115 courses, but many of them are not very developed. For example, the Bird of North American course only lists three birds and the Introduction to Logic course jumps into some pretty sophisticated subject matter, skipping an "Introduction". On the other hand, there is a large library of excellent music courses and some unique course such as how to learn Chinese with your mobile phone and the great work of 19th century British satire, the Egyptian Red Book.
It will be interesting to see how Connexions develops. Any open-copyright learning initiative is a good thing, as it means more and more free courses will be available for us stingy scholars. If you are an expert on any topic, go see how to become an author.

Here is where Rollyo comes in handy. With Rollyo you can set-up and save searches over multiple domains. For the scholar, this is useful in seached through multiple on-line journals. For example, go to the Directory of Open Access Journals (DOAJ) and choose the journals that interest you. Once you set-up your Rollyo, you can search these same sites again and again.
I also like to browse other people's Rollyos to come across recommendations for good sites. Searches for academic or university yield a lot of great university resources and some Rollyo's that I want to save for future use. If you want to see how it works, try my Social Spider Rollyo to search through the most popular bookmarking pages.

From their site:
"This course is all about understanding: understanding what's going on inside your computer when you flip on the switch, why tech support has you constantly rebooting your computer, how everything you do on the Internet can be watched by others, and how your computer can become infected with a worm just by turning it on. In this course we demystify computers and the Internet, along with their jargon, so that students understand not only what they can do with each but also how it all works and why. Students leave this course armed with a new vocabulary and equipped for further exploration of computers and the Internet. Topics include hardware, software, the Internet, multimedia, security, website development, programming, and dotcoms."
If you are like me - and your computer knowledge has come piecemeal through necessity and curiousity - you will enjoy seeing familiar terms and concepts broken-down and explained in a classroom setting. Here's a direct link to the RSS feed and the iTunes podcast feed. Harvard broadcasts an mpeg video version along with mp3s in both feeds.
