QUANTUM MECHANICS, 

Fundamental physical theory that describes the behaviour of matter and of light;

its unusual characteristics typically occur at and below the scale of atoms.

It is the foundation of all quantum physics, includes quantum chemistry, quantum field theory,

quantum technology, and quantum information science.

BIOPHYSICS / BIOCHEMISTRY

Biophysical research shares significant overlap with biochemistry, molecular biology, physical chemistry, physiology, nanotechnology, bioengineering, computational biology, biomechanics, developmental biology and systems biology. The term biophysics was originally introduced by Karl Pearson in 1892. The term biophysics is also regularly used in academia to indicate the study of the physical quantities in biological systems. Other biological sciences also perform research on the biophysical properties of living organisms, including molecular biology, cell biology, chemical biology, and biochemistry.
