Hi everyone! I want to introduce myslef. My name is Matt. I study technical physics and it is funny, beacuse i will be engineer, but i want to work as theoretical physicist in future. I am interested in every field od physics, but my thesis is about muonic three-body Coulomb system. The main reason i created account is that i want to improve my language skills . I hope that i will meet a lot of great people and learn some beautiful knowledge. Thanks! P.S I want to apologize for my future language mistakes!
