Today physics education consists of teaching Newtonian doctrine mixed with data analysis techniques.

This is a strange mixture.

As the result of their education physicists truly believe that when they do data analysis they are doing Newtonian physics!!

To me data analysis and Newtonian doctrine are two different subjects with no relation.

I am trying to understand the relationship between data analysis and physics. I asked this question before but I did not get a clear answer.

Can any one who never studied physics do data analysis?

For instance do I need to know any physics at all to analyze the Cosmic Microwave Radiation?
