SECRETS OF COUNTING WITH INFINITY is a short animated movie about infinity - the word which hides so many mysteries. Small children are already curius about it. How mathematicians work with infinity and the problems and suprises it brings is the message of this movie. Can an infinite series of numbers have a finite sum? We will talk visually about geometric and harmonic series and their sums, about counting with infinity and of course about Zenon‘s paradoxes. Inspirative and mind provoking for all ages, builds ideas of limit and infinity on intuitive level from early years.
