Prime number posters
For years Perfectly Scientific Inc. has been producing high quality posters of the most recently discovered Mersenne primes, which since 1999 have been largest known explicit prime numbers. The posters are printed on thick glossy paper, and are available both framed and unframed. Prices vary, as each new prime tests the limits of the technology necessary to print these high-resolution posters.
Save 50% on orders of any 10 or more unframed posters!

The digits are very clear, but unless you have very, very good eyesight, you will need one of our watchmaker's loupes or an equivalent magnifier to read the digits. |

Earth lights poster
PSI now offers its specially processed version of a NASA composite of the night lights of Earth. The image was originally generated by C. Mayhew and R. Simmon of NASA to show urban development on planet Earth. For more information on this image see Bright lights big city at the NASA site.
We have been fascinated by this image, in which you can see such entities as interstate highways, population density (relative to the incidence of electricity!), and the fractal structure of municipalities. We processed the image with a certain resolution-enhancing filter to render an attractive, high-contrast, 19'' by 38'' poster for your wall. You can also order this poster in a shiny frame with Plexiglas cover.

Poster for prime 237156667−1
Printed on 29''×40'' thick glossy paper after this prime's discovery in September of 2008, the caption of this poster reads:
Shown above is the prime number 237156667−1, having 11185272 decimal digits, discovered (Sep 2008) in Lagenfeld near Cologne, Germany by H.-M. Elvenich, G. Woltman, S. Kurowski, et al. on the Great Internet Mersenne Prime Search (GIMPS) volunteer network and then verified by T. Duell, R. Giltrap, and E. Mayer. The fast arithmetic algorithm used — called an "irrational base discrete weighted transform" (IBDWT) — was developed by R. Crandall, via Mathematica prototyping, then ported to a distributed assembler variant (www.mersenne.org) by Woltman and Kurowski. This and many other algorithms of modern vintage are available from Perfectly Scientific, Inc.
