to try and provide you with an answer,
is split this neatly into two parts:
what I mean by "complex."
a host of formal definitions,
that Einstein and his peers can't do.
ورفاقه على حلّه.
if the clicker works ... there we go.
that when he hits the cue ball,
يضرب الكرة البيضاء
is going to hit the sides,
and where it's going to end up.
up to the size of the solar system,
بحجم المجموعة الشمسية،
the path of the Earth around the Sun,
حول الشمس،
at any point in time.
increase in difficulty,
the Moon in his calculations.
Mars and Jupiter, say,
مثل المريخ والمشترى،
to solve with a pen and paper.
على حلها بورقة وقلم.
a handful of planets,
من الكواكب
or even billions,
to a molecular level.
إلى مستوى الجزيئات.
of an individual air molecule,
لأحد جزيئات الهواء،
of air molecules all together,
من جزيئات الهواء مجتمعة،
which is quantifiable, predictable
planes would fall out of the sky.
across the whole of the world,
with all of these air molecules.
an individual rain droplet
or where it's going to end up.
this is how far science had got.
ما توصل إليه العلم.
with a few objects
التي تحتوي على القليل من الأجسام
with millions of objects
التي تحتوي على ملايين الأجسام
before Einstein's death,
Warren Weaver made exactly this point.
تلك المسألة بالتحديد.
has gone from one extreme to another,
قد عالجت المسائل الصغيرة والكبيرة،
great middle region.
is where complexity science lies,
يأتي دور علوم المسائل المعقدة،
every single problem you can think of

how to improve unemployment.
is going to be a hit or a flop.
سينجح أم سيخفق.
we're completely screwed.
أننا سنفشل فشلًا ذريعًا.
and life is way too complex.
وأن الحياة معقدة للغاية.
of a new area of science
to model our social systems.
لأنظمتنا الاجتماعية.
about statistics and computer simulations.
equations about our society
what's going on
or the weather prediction.
أو التنبؤ بالطقس.
because people have begun to realize
and those of the physical world around us.
of migration across Europe.
والتي تعتبر مشكلة معقدة للغاية.
all of the people together,

this is exactly the same process
it's not burglars and security,

Why you should listen
Hannah Fry completed her PhD in fluid dynamics in early 2011 with an emphasis on how liquid droplets move. Then, after working as an aerodynamicist in the motorsport industry, she began work on an interdisciplinary project in complexity sciences at University College London. Hannah’s current research focusses on discovering new connections between mathematically described systems and human interaction at the largest scale.
