I hold a degree in Physics from Eastern Mennonite University. With a passion for unraveling the mysteries of the universe, I thrive on sharing my knowledge with students. From classical mechanics to quantum theory, I offer clear explanations and engaging lessons to foster deep understanding. Let's explore the wonders of physics together, tackling questions across various subjects.
