• How many pieces of new mathematics are published each year?
• A) 15-20 B) 1000 C) 250,000
• Mathematicians believe that there will be no new mathematics left
to discover by the year 2030 - True or False

Fractal Geometry
Fractal Geometry
A new branch of mathematics
Phenomena in nature that can’t be
described using normal Geometry.
A new age in
computing
Complicated
patterns can be
plotted for the very
first time
By Michael Bradshaw
Mathematicians discovering that
repeating simple rules again and again
can produce wild and beautiful patterns

curve

The Sierpinski gasket
• Your turn to recreate Sierpinski gasket
• And this is what is would look like if you
went one stage further:
What is a fractal????
• Often self similar
• However much you zoom in you still see a
pattern
• Often generated by a simple rule
What’s Special about the
Sierpinski Gasket?
Do other fractals have interesting
properties?
The Koch Snowflake
But are fractals actually useful?
But are fractals actually useful?
Yes!
e.g. in film
