Physics could be described as theory relating to the whole of reality. That is, physics is about everything.
It's just that some things like human relationships are so complex that bringing them down to physics would be almost impossible. Yet, it is physics that describes even human relationships.
I know you don't think this could be true but physics is just so interesting that it's interest is impossible to quantify. I can't convince you, I know that. But Physics Girl might just light a fire of interest within you. To see if this is true, look at some of the YOUTUBE videos which have been produced by Physics Girl.
Here They are.
Just click on the YOUTUBE tab on this web site.
You have a whole lifetime ahead of you so spare a few minutes to give these videos a chance to inspire you.
Maybe the few minutes will turn into a few hours and you might never notice.
