I will be doing a presentation in the science symposium at my community college. The common theme is always topics from biology or chemistry but never from physics or mathematics.. I am a Math major and love pure mathematics, I am interested in presenting the great theorems of mathematics inspired by William Dunham's book called " Journey through the genius". The presentation will be around 12-15 minutes where I will try to present some of these theorems in the most interesting way. Other topics I had in my mind were Quipu : The mathematics of the Incas. Number theory and Golden ratio. Any other suggestions would be greatly appreciated.
