Forrest M. Mims III

Scientific Research, Books, Articles, Columns, Lectures and Photographs

Publications

Getting Started in Electronics has sold more copies than any other book about electronics. The book was written for Radio Shack, where it sold more than 1,300,000 copies. "Getting Started in Electronics" and the Forrest Mims Mini-Notebook series are now published by Master Publishing and can be ordered from the Master Publishing site at www.forrestmims.com. The book is available at amazon.com and is once again in Radio Shack stores.

The Citizen Scientist (www.sas.org) carries my columns about many aspects of science.

NEWEST BOOK

Fifty Years of Monitoring a Changing Atmosphere: The Story of Hawaii's Mauna Loa Observatory. This 265,000-word book was written on assignment from the US National Oceanic and Atmospheric Administration (NOAA). The book has been extensively revised and expanded following three rounds of reviews by a 25-member panel of scientists and former staff of the Mauna Loa Observatory. It was recently recommended for publication following a 5-month review by two readers retained by the University of Hawaii Press. The expected publication date is late 2009. See Home Page for more information.

INTRODUCING "THE COUNTRY SCIENTIST"

My weekly science column in the San Antonio Express-News is called "The Country Scientist." These columns will eventually be supported by a new web site. For now, supplemental information for some columns may be appended to the column listing below. (Please scroll down to the end of this page for the most recent installment.)

9. REJECTED PUBLICATIONS

While most of my scientific papers and articles have been published, some were rejected. One, by my son Eric and me, was a paper submitted to Nature that would have been the first to report reduced ozone in the ozone layer following the volcanic eruption of Mount Pinatubo in 1991. One of the reviewers felt that my homemade instrument that detected the reduction (TOPS-1) was too unknown. Another rejected our findings outright. Yet other papers reporting the same phenomenon were eventually published in various journals. (TOPS-1 later found a significant drift in NASA's TOMS ozone instrument on NIMBUS-7, a finding that I published in Nature .) In view of the growing number of papers reporting function and purpose for "junk" DNA, it seems appropriate to post here a letter that was rejected by Science in 1994 (a similar letter was rejected in 2003):

1 December 1994
Letters
Science
1333 H Street, NW
Washington, DC 20005
To the Editor:

Finally, Science reports "Hints of a Language in Junk DNA" (25 November, p. 1320). Those supposedly meaningless strands of filler DNA that molecular biologists refer to as "junk" don't necessarily appear so useless to those of us who have designed and written code for digital controllers. They have always reminded me of strings of NOP (No OPeration) instructions. A do-nothing string of NOPs might appear as "junk code" to the uninitiated, but, when inserted in a program loop, a string of NOPs can be used to achieve a precise time delay. Perhaps the "junk DNA" puzzle would be solved more rapidly if a few more computer scientists would make the switch to molecular biology.

10. PEER REVIEW

In spite of its many flaws, peer review has served an important role in improving some of my scientific publications. Some scientists who are requested by a journal editor to review a prospective paper assign the task to a graduate student or some other less qualified individual. This is a serious abuse of the peer review system, for the reviewer is not necessarily a peer of the author(s).

I have reviewed papers for several leading scientific journals. The papers were about sun photometry, ultraviolet radiation, waves in the ozone layer during various solar eclipses and other atmospheric topics. Additionally, I have served as a paid reviewer for NASA, the National Science Foundation and for a number of textbooks for McGraw-Hill, Academic Press and Prentice-Hall.

An especially interesting (and compensated) review assignment was the Atlas of Science Literacy , Volume 2, American Academy for the Advancement of Science Project 2061 (2007). This project, which was supported by the National Science Foundation, is part of a major program to significantly improve science, mathematics and technology curriculum for "all Americans."
