Defining Pi for Physics

The video tutorial explains the mathematical constant π, its definition as the ratio of a circle's circumference to its diameter, and its nature as an irrational number. It uses a practical example with a frisbee to demonstrate how π is calculated. The concept of radians is introduced, explaining their dimensionless nature and their role in physics. The tutorial also clarifies the use of symbols and abbreviations, emphasizing the importance of clarity over brevity in scientific communication.
