Why hello there, I didn't see you waving! With your new gargantuan wave model, you'll never have to miss a wave again. Transverse, interference, standing waves, nodes, this lovely science giant has got it all. Put it up in a classroom, at a homemade science museum, or to wow your auntie at the next family reunion. Let's model! What: Giant Wave ModelConcepts: waves, transverse waves, interference, nodes, periods, amplitude, particle motionTime to make: ~2 hoursCost: $15 not using wooden balls, another 40 withFun: foreverMaterials:Cord (about 40 ft)Big straws (40 or so)Wooden dowels (we started with 5 x 4' sections of 3/4" dowels)Weights for ends (we used 1.5" craft wood balls)2 Carabiners (optional, good for mounting) Tools:DrillScissorsSome needle tool (to help push string through holes)Onwards! Thank you to noahw and Robb for being excellent wave model models. :)

A very nice list of Robots and Gadgets for the Google Wave.

Remember, this is still all quite new, so things may not work as you would hope. But when they do, it's SO much fun. :)

Might be a useful tool for lecture when Wave becomes part of Apps.

The internet is a little like the proverbial elephant that never forgets. Our digital footprints are not like the footprints on the beach, washed away by the next wave or rising tide. Rather they are like footprints left to dry in the wet concrete of the footpath. Permanent. The Digital Citizen will follow six tenets of citizenship.

"A mesmerising animated map is weather and other data layers, including winds, wave direction and and height, clouds, CO2 concentration and much more."

I think those who think that we will not need keyboards are missing a few important points. Here's the issue - I can type faster than I can talk. Also, in the classroom - 20 kids talking to their computers it would be chaos and a mess. Typing, however, has a speed benefit and doesn't require a "cone of silence" as a everyone talking to their glasses would. I think keyboarding will remain part of the productive equipment of most of us - until our devices can read our brain waves. For those who type less than 30 words a minute and work in a quiet office, this is likely to be true. Meanwhile, this is a great read about what will happen in our homes, at least.

That notion has helped to rekindle the browser wars and has resulted in the latest wave of innovation. Firefox 3.0, for example, runs more than twice as fast as the previous version while using less memory, Mozilla says. The browser is also smarter and maintains three months of a user's browsing history to try to predict what site he or she may want to visit. Typing the word "football" into the browser, for example, quickly generates a list of all the sites visited with "football" in the name or description. Firefox has named this new tool the "awesome bar" and says it could replace the need for people to maintain long and messy lists of bookmarks. It will also personalize the browser for an individual user. "Sitting at somebody else's computer and using their browser is going to become a very awkward experience," said Mitchell Baker, chairwoman of the Mozilla Foundation.

People obsess over the latest flavors and innovations in digital communication and interactivity. I'm talking about everything from new email technologies to social networking tools, even new hybrid interaction platforms like Wave. Many of these innovations are exciting and have permanently earned a place in our lives. Their growing popularity drives volume and efficiency of one-to-one communications.
