'Physical Reality', sounds strange doesn't it ? Is there a reality that is not physical ? You think to yourself; 'This could be one of those strange terms that specialists who come to speak on Chnadrayan or LHC might use!'. Luckily it isn't. It's just a complex word for Feynman's Red ball that does weird stuff. One of the things I love to do is to read up Physics. After being introduced to 'Advanced Physics' so to speak (well better than +2 at least) I have found it to be full of equations of all kind. You want to model a pendulum swinging or a coconut falling, you just make a few (or a lot sometimes :) ) assumptions, then write down equations which deals with whatever quantities you want and try to solve them and what they say. Looking at this, it is quite tempting to say that solving equations is physics. Even I did think that for a while. But now what I've started to think (might be wrong though) is that equations just summarize a pictu...
