"Display resolution versus pixel resolution Those figures both refer to pixel resolution, a stat that until last year generally didn't differ from display resolution. The difference is important, and I continue to be annoyed that neither Apple nor Google make it easy to understand what display resolutions their screens show. The difference between the two can be summarized like this: Display Resolution: How much can you see on a screen Pixel Resolution: How clear or sharp the image is that you see Display resolution: how much you can see 

"How to Get Started Make sure you already have a Google+ account (and optionally a company page), then follow these steps. Install (or make sure you have installed) the Google Talk plugin. Follow all of the instructions to install the plugin. Then login to your Google+ account (see image for placement of steps): Click the link to "Start your own hangout" in the right column. Check in the top right corner and select the personal account or company page you want to use to host this hangout. If you have multiple cameras and microphones connected to your computer, make sure you select the one you prefer to use first. Invite an entire circle, individuals or select Public. The interface to start a hangout has a clean, simple design. Here some tips for successful hangouts: Give yourself time to practice. I'm part of a group of women on Google+ who routinely test out new features privately before we open up public hangouts. Create the list of people you want to invite by putting them all in a circle. Then just invite the circle. Create any documents you are going to share ahead of time in Google Docs to easily add them to the hangout."

"To produce the jaw-dropping video you see above, YouTube user Brusspup took a subwoofer - a speaker which provides deep bass tones for music - and set it to the same frequency as the frame rate of his video camera."

What do you use your USB flash drive for? Perhaps you store work documents, photos, music, or movies on them. If you think they're cool because you can store and transport files with them, wait till you see what else you can do with them.

Make called Bill a "brilliant science-and-technology documentarian", whose "videos should be held up as models of how to present complex technical information visually" Wired called them "dazzling." Scientific American's blog called him a "smart, easygoing everyman with a firm understanding of the science." You can see 10 of his best videos below. He takes apart an LCD monitor, demonstrates how fiber optic cables work, rips up a hard drive, explains the wonder of a quartz wrist watch, solves the mystery of black boxes, blows up a light bulb filament, reveals how amazing a pop can tab truely is, shows why a cell phone looks like it does, and explains why you always seem to be in the slowest line.

It began with a styrofoam coffee cup; you could call it the first koostik. I was curious to see if fitting a little megaphone to the bottom of my iPhone would passively amplify the volume of the external speaker. It did, but it wasn't much to look at. For a year after that first experiment, I made dozens of prototypes in wood in my home workshop. With each new piece I was getting a little closer to the goal of a balance between aesthetics and functionality.

"How-to video: Creating a digital classroom project, using Glogster Brief synopsis: With Glogster's education platform, located at edu.glogster.com, teachers can expand their use of the web-based poster creation tool, Glogster. The edu Glogster site gives teachers more power than the standard Glogster application. With the educational Glogster Web 2.0 application, teachers can register their students for their own glogster accounts, all of which are contained in the teacher's Glogster account. Students can complete projects on one unit (see how-to video above) and those projects can be shared in the classroom Glogster site."

"At first glance, the winning images from the 2010 Olympus BioScapes Digital Imaging Competition--put on by the camera company's U.S. arm--look like distant worlds or psychedelic moon landscapes. But take a (much) closer look, and you'll see the images are of life science specimens that surround us every day: seeds, insects, plants, animals, and eyes... "

"This week's Cool Tool, the new Pulse digital pen from LiveScribe, is still undergoing my evaluation since I've only had it about a month now, but it has already lived up to its predecessor, the now discontinued io2 digital pen from Logitech, which I nominated as a previous Cool Tool. I can see that this new Pulse pen has much more to offer, so I thought it worthy of bringing to your attention. "
