Physics teacher | Tutor for 10 years

I hold a degree in Physics from New Mexico Tech. With a passion for unraveling the mysteries of the universe, I thrive on sharing my knowledge with curious minds. Through interactive sessions, I simplify complex concepts, making physics accessible and engaging for students. Whether it's classical mechanics or quantum theory, I foster a supportive environment where questions are encouraged and critical thinking flourishes. My goal is to inspire a lifelong love of learning and empower students to explore the wonders of science. Let's embark on a journey of discovery together!

## Questions
