from Egyptians measuring with the Sun to
modern algorithms for self-driving cars
here is our 20 episode series the
history of math it represents a
fascinating journey through human
civilization

mathematics simply didn't exist so how
how did it start finally probably the
first step was to count archaeologists
for example have found bones with
engraved
- definitely this shows people when they
started to count calculus for example
the word calculus comes from Latin
calculus which means a little stone a
pebble and people used to use stones to
count that was the first step and then
the first big thing what happened
somebody probably in the area of Iraq at
the time was called Mesopotamia measures
Potamus between the two rivers the Eiger
and Fratus somebody suddenly realized
that he was looking at three apples and
three dogs that's hey there must be
something common between those two sets
number the digit 3 was born yes in fact
there is a common characteristics
between the two sets 3 the digit it
looks obvious but it was not and
suddenly it became possible to Conan -
right what was common between the two
sets of course it was great but
immediately there was a limit how do you
count for example
the people in the village how do you do
you cannot have any infinity of digits
so the next step was to combine digits
and indeed with two digits you can have
a lot of quote numbers the number was
born that's that that's the next step
the number certainly it became possible
to count large numbers like how many
hairs I have it suddenly became possible
and several systems were designed
developed by different people around the
world one of the most famous for example
is the Roman system the Roman Empire of
Roman people used to use seven digits
and whis combination they could count
infinity amounts and it looks like
another big progress but there was a big
problem for example you can write
eighteen takes V 1 1 1 that is 18 but
now imagine you want to add 18 + 2 + 2
how do you do there is a problem it's
not easy at all the problem
no 0 it's hard to realize and to
understand how it's possible for the
Roman Empire not to have a digit for 0
and it came many centuries afterwards it
came from the East India Hindu Arabic
and somebody may be called al-khwarizmi
and from this side came the ID of the
zero it was not immediately accepted
because a digit to qualify something
that doesn't exist there was some
resistance to that again it looks
obvious it was not but with the zero
suddenly another air suddenly became
possible and that's the history of
mathematics it's a sequence of steps and
each of those steps have made some
progress and led to the world we are
living in today join us next time to see
how Egyptians invented geometry and use
it for example to calculate the size of
the earth subscribe now to follow the
