the concept of zero. His circle had a stick at the end
different form the others but most importantly his zero
can be used all alone which makes it an independent
number not just a concept functioning as a placeholder.
Even though the positions of that sign were strictly
restricted, this can be considered as the first modern
zero concept of the old world.
The concept of zero is brought to the Europa via
Arab Peninsula, Spain –Muslims lived there have
carried it through- and the nation of Moors. An Italian
mathematician named Leonardo of Pisa, also known as
Fibonacci, brought the Arabic numbers to the Europe
in year 1202. Eventhough at first he talked of it as an
operation just like multiplication division etc., through
the end of the thirteenth century the idea and the
usage of zero become common in Europa. Until the
early sixteenth century they used to use the Arabic
numerals on the Europe more dominantly.
So, as we talk of the number zero, it’s logical to say that it
is not the invention of a man or even a group. During all
the period on the timeline from the first urbanizations
to the Medieval Ages zero had a development. The
knowledge that is known about it have been progressed
and we learned more about it. Nobody could 100%
assure that it will stay as it is right now till the end of the
world. Invention of it has made us move to the better. It
made some concepts easier than they used to be. Also
a big mystery has been unrevealed as far as we know.
How can anything represent nothing?

MAGIC OF A SNOWFLAKE
Amazingly, snowflakes always have 6 sides and similar to the
human print, it is thought that no toe snowflakes are ever
exactly the same. Both the form and shape of a snowflake
depends on the temperature and mixture content of the
cloud. Snowflakes can be categorized into 6 main types;
plate, column, stars, needle, and capped column.
If we had the opportunity to inspect all the snowflakes, we
could see that all of the snowflakes are different from each
other. The reason for that is the molecular structure of the
water molecules, therefore the snow crystals are formed in
different geometrical shapes.
The most interesting fact about snowflakes is that all of
them are perfectly and flawlessly symmetrical. When
the amazing structure of snowflakes was discovered, the
scientists from all over the world were impressed.
It is such a great miracle that all of the snowflakes have
hexagon shape and different from each other.
The world’s largest snowflake ever snowflake was found 38
centimeters wide and 20 centimeters thick. This snowflake
occurred at Ford Keogh, Montana, USA on 28 January 1887.
