# What Is So Special About The Number 1.61803?

PHI(φ) is an irrational, non-terminating number as PI(π), but its significance is far more than PI(π) ;

Π = 3.14159265359…(pi)

Φ = 1.61803398874…(phi)

The Golden Ratio (phi = φ) is often called The Most Beautiful Number In The Universe.

The reason φ is so extraordinary is because it can be visualized almost everywhere, starting from geometry to the human body itself!

The Renaissance Artists called this “The Divine Proportion” or “The Golden Ratio”.

The Fibonacci numbers and Hilbert’s 10th problem

Julia Robinson was born on December 8, 1919. She was a brilliant mathematician, generous research collaborator, and kind human being who faced some trying circumstances with a great deal of grace. I wrote about her life and work for Science News in honor of her 100th birthday.

Most of Robinson’s research focused on decision problems: given a particular set of conditions, can one tell whether an arbitrary problem has a solution or not? Specifically, she spent much of her life studying Diophantine equations, polynomials with whole number coefficients, like x2+2xy-3y2=0. Some Diophantine equations have whole number solutions (in the above, there are many: x=3 and y=3 is one), and some do not.

# Fibonacci, el matemático que se puso a contar conejos y descubrió la secuencia divina

Durante los siglos en que China, India y el imperio islámico habían estado en ascenso, Europa había caído bajo una sombra.

Toda la vida intelectual, incluido el estudio de las matemáticas, se había estancado.

Pero en el siglo XIII, las cosas estaban empezando a cambiar.

Liderada por Italia, Europa empezó a explorar y comerciar con el oriente.

Con ese contacto llegó la difusión del conocimiento oriental hacia occidente.

Y sería el hijo de un funcionario de aduanas quien se convertiría en el primer gran matemático medieval de Europa.

# This Artist Creates Stunning Glass Sculptures Using Fibonacci Ratios

Jack Storms is a remarkable artist who works out of Los Angeles.  He has mastered a phenomenally rare style of glass art work combining lead crystal and dichroic glass using a cold-glass process.  The number of glass artisans working in this form of fine art could be counted on one hand.

# Fibonacci and his Magic Numbers

Leonardo Bigollo (Leonardo Pisano or de Pisa) was a mathematician who lived in Italy between the 12th and 13th century (1170-1240) and who turned to turn his back on the Roman numerals system that prevailed at that time. He has been known throughout history by his nickname: Fibonacci, a derivative of adding the words fillius + bonnacci which, in Latin and Italian mean something along the lines of “son of the well intended”. Apparently, Fibonacci’s father (Guglielmo) was a good person, as well as being a trader, travelling through North Africa. It was there that his son Leonardo discovered the magic of Arabic numbers.
