The video tutorial introduces imaginary numbers and their representation on a plane, leading to a discussion on the Mandelbrot set, a famous fractal named after Benoit Mandelbrot. The teacher explains the concept of fractals, highlighting their scale symmetry and infinite detail. The tutorial emphasizes the complexity and beauty of fractals, demonstrating how zooming into them reveals endless patterns and shapes.
