This panoramic photo was created using Canon's PhotoStitch software. This software allows you to interactively choose where the overlap fields in the photo will occur. Then it crops the entire image to allow it to fit in a rectangular frame.

Common Sources for Various Chemicals

Aaron Muderick

As the years have gone by, it has become more difficult to purchase many common chemicals.  Paperwork, restrictions, and exorbitant hazmat shipping fees are often required when ordering from traditional chemical supply houses.

An Optimum Combination

Michael P. McLaughlin

I never thought that I would ever write a computer game. I am a scientist, and our attention is typically focused elsewhere. Still, problems do arise, sometimes computational problems and, every once in a while, the solution technique proves as interesting as the original task.

How to Discover Asteroid Impacts: The Story of the Discovery of Two Impact Craters

Emilio González
Astroseti.org
Monjos, Barelona, Spain

On 6 March 2006 I published at Astroseti.org a translation into Spanish news about the discovery of Kebira impact crater, a 31-km (19-mile) diameter structure in Egypt, on the border with Libya, by investigators from Boston University.

We have read in the media that Professor Pianka has received death threats as a result of media reports about his speech at the Texas Academy of Science. And I also want to inform our readers that I have received via email such a threat as a result of my editorial about his speech as well as obscene and abusive email and phone calls.

I want to make this crystal clear: The Society for Amateur Scientists deplores all threats or use of intimidation for any purpose whatsoever. If any information comes to our attention regarding who is taking this despicable action against Professor Pianka we shall immediately forward it to the proper authorities with our fervent hope that they will prosecute the perpetrators to the fullest extent of the law.
