This 97-digit number is a prime, divisible by only 1 and itself. But, add 210 to it, and you get still another prime. Add another 210, and another prime pops up! You can do this six times and gets a series of seven consecutive primes in an arithmetic progression. Neat! And just a tiny bit of order in the distribution of primes. It took H. Dubner and H.L. Nelson about two weeks with seven computers running continuously to come up with this discovery. It seems relevant to mention that these gentlemen are semiretired and retired, respectively. (Peterson, I.; "Progressing to a set of Consecutive Primes," Science News, 148: 167, 1995)

Comment. There are other traces of order in the distribution of primes. See SF#42/332. (We are crossreferencing by SF# and by the /page number in the book Science Frontiers, in which the first 86 issues of SF are collected, organized, and indexed. Details here.

From Science Frontiers #102 Nov-Dec 1995. 1995-2000 William R. Corliss

Science Frontiers Sourcebook Project Reviewed in:


  • "A sourcebook of unexplained phenomena is therefore a valuable addition to a collection of scientific literature. William R. Corliss has provided this in the past with his source books of scientific anomalies in several subjects, and now he has provided it for astronomy. He has done an excellent job of collecting and editing a large amount of material, taken in part from scientific journals and in part from scientific reporting in the popular or semi-scientific press." -- "The Mysterious Universe: A Handbook of Astronomical Anomalies", reviwed by Thomas Gold, Cornell University, in Icarus, vol.41, 1980

  • "An interesting, systematic presentation of unusual weather [..] This book is recommended for a general audience" --"Corliss, William R., Tornados, Dark Days, Anomalous Precipitation, and Related Weather Phenomena, Sourcebook Project, 1983.", revieweed in Choice, September 1983
  • "..the science is necessarily somewhat speculative, but Corliss's symthesis is based on reputable sources." -- "Corliss, William R. (Compiler). Lightning, Auroras, Nocturnal Lights, and Related Luminous Phenomena" reviwed by Joseph M. Moran, Univ. of Wisconsin in Science Books and Films, Sep/Oct 1983

  • "Before opening the book, I set certain standards that a volume which treads into dangerous grounds grounds like this must meet. The author scrupulously met, or even exceeded those standards. Each phenomenon is exhaustively documented, with references to scientific journals [..] and extensive quotations" -- "Book Review: The moon and planets: a catalog of astronomical anomalies", The Sourcebook Project, 1985., Corliss, W. R., Journal of the Royal Astronomical Society of Canada, Vol. 81, no. 1 (1987), p. 24., 02/1987
