Robert Penner is a famous flash Guru, brilliant Flash developer, a consultant, best writer of many books, and a technical speaker.
Robert Penner is known across the world for his technical innovations and organic style. His working areas are:

• Robert Penner Easing Equations: Robert is probably the first person who wrote equation of easing in a simple manner and which is now used all across the world. He also described application of mathematics and physics in flash. The best part is that his applied knowledge has been incorporated into flash CS3.

• Robert Penner back button application: This is a victory of flash usability. Just think about you have 5 different MovieClip/Graphics on 5 different linear/non linear frames. One next/back button for traversing each frames. And there is a requirement that your browser navigation panel should also work like the same. Just try out Robert Penner back button application. He is the first person who achieved this.
• Effects: He has done so many effects applying Mathematics and Physics. Some of the examples are : MusicRain Player, Wine Cellar Builder, Axis Interactive v2.0, fractal dancer , streakers , photon hoop , disco flakes , sphere burst , cyclone, and much more.

My suggestion:
If you are a beginner and willing to know how to apply physics and Mathematics in flash you must Read Robert Penner.
