GET RID OF BIOLOGY AND CHEMISTRY

explain everything with physics.
scientists should strive to explain everything as accurately as reasonably possible and as simplified as possible without oversimplifying. Physics is the best field we have available for such a task.
everything else is just remnants of ancient systems of trying to explain the nature of reality, and quantum physics is not well understood yet.

You might be able to explain a lot with physics, but acctually researching and understanding what happens requires approching the problems from a different angle.

Physicists don't know when and why to use 2-D agarose gel electophoreisis in relation to genomics. Physicists won't know the wider implications of discoveries as they don't have the wider knowledge to put it into context.

No subject is better or worse, they just have different skills that are all needed to progress science in a practical and empirical manner. Sure, physics gives us the final reason why our experiments are worthwhile for our purposes, but that does not mean is encompasses everything to do with Biology or Chemistry. What it does mean is that all branches of science need to have amicable relationships with each other and to work together to solve problems and make new discoveries. If not, then we are only hurting science and the human race.
