That was my worst subject in school! It always seem way to compex for me
Yep its quite complex since its one of the most fundamental scientific disciplines.
Do you know who they consider the most knowledgeable person in the world for physics? 
Probably Stephen Hawking, since he contributed to advances in the understanding of electromagnetism.
What else can you tell me about Physics?
Well physics intersects with many interdisciplinary areas of research, such as biophysics. So its not some stand alone subject.
What kind of careers can you do with pshsics?
