I am a Physics enthusiast. I specialized in Mathematical and Theoretical Physics. I love giving to the world for free. I want to make an impact in my own way. Many students find physics a difficult subject, so I came up with the idea of this website to make their journey in physics an easy one. Feel free to contact me when you have a problem with physics calculations. More About Me Welcome to Physicscalculations.com! I’m Abbas Nura, a passionate and dedicated physics educator, and I’m excited to share my love for physics with you through this platform. My goal is to make physics accessible and enjoyable for all students, helping them excel in their studies and develop a deep understanding of the subject. With a wealth of experience in both education and health advocacy, I bring a unique perspective to the world of physics education. I started my journey in 2010, working with the Health Education Initiative for Women (HEIFOW) immediately after graduating from Kano University of Science and Technology (KUST) Wudil, where I earned my bachelor’s degree in physics. This experience opened my eyes to the power of education in empowering individuals, particularly children, teenagers, women and men, to make informed choices about physics. In 2012, I ventured into teaching physics, and it has been a truly rewarding experience. I firmly believe that physics is not as challenging as it may seem, and my passion for the subject drives me to create engaging and effective learning experiences. As a result, an impressive 90% of my students consistently pass my lessons with top grades, often achieving A’s in their exams. To enhance my teaching skills and knowledge, I pursued a Postgraduate Diploma from the National Teachers Institute of Nigeria (NTI). This program equipped me with advanced teaching techniques and pedagogical strategies, enabling me to tailor my lessons to meet the diverse needs of my students effectively. Fueling my thirst for knowledge, I obtained a Master’s degree in Theoretical and Mathematical Physics from the University of Abuja. This rigorous program expanded my understanding of physics and honed my analytical and problem-solving skills. It allows me to delve into the intricate theories and concepts that underpin the laws of the universe. As a registered professional with the Teachers Registration Council of Nigeria (TRCN), I am committed to maintaining the highest standards of professionalism and ethics in the teaching profession. I continuously strive to stay updated with the latest advancements in physics education, ensuring that my students receive the most relevant and comprehensive instruction.
