 "REALLY Bright and Brig" 2009-11-17
By Bette O (Alexandria, Virginia)
I love being able to tell time at night. This clock's display is REALLY big, which is what I wanted since I could not tell time without my glasses. HOWEVER, it is SO bright that I had to tape a sheet of green translucent plastic over the display because it lit up the entire bedroom. The alarm is really loud, also, which scares me to death when it goes off. And, as far as I can figure out, you can only set the alarm at the clock, not with the remote (but I may just be technologically challenged.) I use the remote to turn the alarm on and off, and for snooze.



For the next design round: please put a dimmer switch on the light, and a gradually increasing alarm (or have two different tones for the alarm). Thanks!

 "Great Clock" 2009-01-20
By Su Bell (Weatherford, TX)
We purchased this clock for our bedroom and love it. It was easy to set and the numbers are nice and LARGE so you can read it without glasses on. It is a wall alarm clock so it came with a remote. We don't use the remote so that my husband HAS to get up out of bed to turn the alarm off.

 "exhaustive listing/discussion of Greek and Latin as used in scientific context" 2008-07-13
By Laurie J. Neverman (Denmark, WI United States)
I was looking for a book that might list Latin names of common beasties, this is much more than that. The book contains a very thorough listing of Greek and Latin words commonly used in science, how to use them properly, examples of their various forms in usage (singular versus plural, different forms of the word itself), and the nomenclatural history of certain science areas. There is a LOT of information packed into this volume. I think it would be a useful reference volume for anyone studying Greek, Latin or any of the sciences that rely heavily on the use of this type of nomeclature. It's just a plain interesting book to look at for the layperson as well.

Phantom Risk: Scientific Inference and the Law

Buy Cheap Phantom Risk: Scientific Inference and the Law

Buy Low Price From Here Now
Phantom risks are risks whose very existence is unproven and perhaps unprovable, yet they raise real problems at the interface of science and the law. Phantom Risk surveys a dozen scientific issues that have led to public controversy and litigation - among them, miscarriage from the use of video display terminals, birth defects in children whose mothers used the drug Bendectin, and cancer from low-intensity magnetic fields, and from airborne asbestos. It presents the scientific evidence behind these and other issues and summarizes the resulting litigation. Focusing on the great disparity between the scientific evidence that is sufficient to arouse public fears and that needed to establish a hazard or its absence, these original contributions probe the problem of scientific ambiguity in risk assessment, and the mayhem this creates in the courtroom. Although the authors are clearly optimistic about the use of science to detect and evaluate risks, they recognize the difficulty of inferring cause-and-effect relationships from epidemiological (observational) evidence and of inferring risks to humans from high-dose animal experiments, the two major sources of evidence. The final chapter reviews the exceptionally difficult problem of how the legal impact of disputes about phantom risks can be reduced. Kenneth R. Foster is Associate Professor in the Department of Bioengineering at the University of Pennsylvania. David E. Bernstein is an attorney at the law firm of Crowell & Moring. Peter W. Huber is a Senior Fellow of the Manhattan Institute for Policy Research and serves as Counsel to the law firm of Mayer, Brown & Platt.

This is a clever device that uses two thermometers to record the high and low temperatures in a space like a greenhouse, or a garage, or a hen house. Little floats inside the columns are reset with a magnet on a string. I like it especially because it is such an elegant low-tech time-tested solution. It looks terrific and if you think you need one, get two, because you will want another one for sure.
