Feature

During the week of 30 Dec., I caught part of a Discovery Channel program about glass. They said that glass, being a “super cooled liquid”, would flow over time, and that a pane of old window glass will become thicker at the bottom than it is at the top.

Please! Please! Please! Can we put an end to this urban myth once and for all?

Glass: Liquid or Solid -- Science vs. an Urban Legend

Here is, I hope, the final word on the topic from Robert H. Brill, Research Scientist, Corning Museum of Glass --- You know, the “Glass People” ---- Does Glass Flow? No, It Doesn't Flow!

Wanderings

Have you ever wanted to get into robotics but could not justify the expense or perhaps you thought that you lacked the mechanical dexterity to construct a robot platform?

If so, maybe you could talk yourself into buying a robot vacuum cleaner ;-)  Have a look at the Roomba robotic vacuum cleaner that's produced by the iRobot Corp.

The nice thing about the Roomba is that its designers included a USB port that allows you to interface your computer to the unit's electronics enabling you to “hack” the software.

Get a copy of Hacking Roomba BEFORE you purchase your vacuum so that you get the model that the book covers.

Also, check out the Roomba Review web site.
