Phi ( Φ = 1.618033988749895… ), most often pronounced "fi" like “fly,” or phi (0.618033988749895…) pronounced "fee", is simply an irrational number like pi ( p = 3.14159265358979… ), but one with many unusual mathematical properties.

What makes a single number so interesting that ancient Greeks, Renaissance artists, a 17th century astronomer and a 21st century novelist all would write about it? It’s a number that goes by many names. This “golden” number represented by the Greek letter Phi, is known as the Golden Ratio, Golden Number, Golden Proportion, Golden Mean, Golden Section, Divine Proportion and Divine Section. It was written about by Euclid in “Elements” around 300 B.C., by Luca Pacioli, a contemporary of Leonardo Da Vinci, in “De Divina Proportione” in 1509, by Johannes Kepler around 1600 and by Dan Brown in 2003 in his best selling novel, “The Da Vinci Code.” With the movie release of the “The Da Vinci Code”, the quest to know Phi was brought even more into the mainstream of pop culture. The allure of “The Da Vinci Code” was that it creatively integrated fiction with both fact and myth from art, history, theology and mathematics, leaving the reader never really knowing what was truth and what was not. This site studies this golden number Phi, and its mathematical cousin, the Fibonacci sequence (0, 1, 1, 2, 3, 5, 8, …) , both of which have roles in the plot of this murder mystery, and distinguishes between the myth and the math.

About NanoRosetta®

We believe in connecting generations and preserving legacies forever on a tiny format that lasts forever.

NanoRosetta is an innovative way to record stories in metal that lasts for thousands of years on a medallion the size of a dime. Pass it on for generations.

Photos and stories are nano-engraved on a shiny metal medallion and sealed with a crystal and easily retrieved with just light and optics.

All pendants and dog tags can be customized with engraved names on the back for that perfect unique gift.

NanoRosetta® is the high speed technology behind the nano-engraving process. The patented process creates 5 billion pixels image to make up a yearbook. This is five times larger than NASA’s largest image ever taken of the Andromeda galaxy.

To recover the images, we use a 20 Megapixel camera or a lab quality microscope. In the near future all the photos on the medallion will be easily recovered by a mobile phone.
