Hi Tingles,
What does today's decorations on the Google Trademark signify?
The Julia fractal decorations on the Google logo today are to honor
the 111th anniversary of the birth of mathematician Gaston Maurice
Julia, born on February 3, 1893, in Sidi Abbes, Algeria.
Before fractals got their name, many curious mathematical sets that we
have come to recognize as "Fractal", were known and studied. The
science really started in the late 19th and early 20th century. Many
great mathematicians pioneered the field and made critical advances
that made future work possible. One of them was Gaston Maurice Julia.

Gaston Maurice Julia - Julia set's conceptual father
?Even though everybody who knows about even a little about fractal
geometry, and especially about the Mandelbrot set, is also familiar
with the name of Julia?since both of these sets are tightly
interconnected?it seems little is known, generally speaking, about the
life of the Julia set's conceptual father, Gaston Maurice Julia.?
?In 1918, at the age of 25, he published a 199-page article in the
Journal de Mathematic Pure et Appliqué (pp. 47-245), "Mémoire sur
l'itération des fonctions rationnelles", in which he discussed the
iteration of a rational function, a topic that was also studied by
another contemporary Frenchman, Pierre Joseph Louis Fatou?1878-1929?at
the same time and in a similar way, but from different perspectives.
In that article, Julia precisely described the set J(f) of those z in
C for which the nth iterate fn(z) stays bounded as n tends to
infinity. This work was so important that he received the Grand Prix
de l'Académie des Sciences (France)?
?Notwithstanding that sudden fame, his work became almost forgotten,
until many decades later Benoît B. Mandelbrot?years after his own days
at the École Polytechnique in Paris, where Julia was professor of
mathematics, and where he came in contact with Mémoires for the first
time?brought it back to the forefront through his own renowned
workings in what soon became to be known as fractal geometry.?

More about fractals:
?There are four people who made significant contributions to the
development and experimentation of fractals: Henri Poincaré, Pierre
Fatou, Gaston Maurice Julia and his student, Benoit Mandelbrot.?
Gaston Julia who studied Julia sets during the early 20th century.
?However, Mandelbrot was the first to actually "discover" fractals.
While he was examining the shapes created by Julia, he tried to
classify the shapes by using a repeating equation and "graphing" it.
He worked for the IBM company and it was then when computers were used
to examine and develop fractals.?
