There are many paths to study in science and is very wide. If you interested in particle science, may study it, all brunch of science is very tub. Mainly, those who are week in Math, it is very difficult to win in that field.
To solve this hard path, I written the book Complete Unified Theory. There is no hard math to solve higher field of science. In science, mainly Physics and Astrophysics we find that lot of complex math brings some result. Every scientist has own theory, all together established the present SCIENCE. But complete unified theory is single theory, with the help of this theory we can solve known and unknown facts from particle to the universe. This theory is very unique and 1st time in the scientific world. I am touching some example here which scientists failed to give answer.
1) Accurate mass of a photon, graviton particle.
2) Maximum mass of the Universe.
3) Structure of electron, electromagnetic radiation.
4) Internal functions of m of Einstein equation E = mc2 at excited state of matter m.
5) Effect of a photon in leaf of plant during photosynthesis.
6) Nature of unknown elements.
7) Internal functions of fission reaction of Uranium like elements.
8) Why particles give to birth?
9) Quantum circulation of Black Hole.
10) Birth of the universe.
And so on.
I solved all by my single theory. There is no single theory which can solve all facts like above in our present science. So, complete unified theory is the master key of the universe.
