There isn't a definitive list of exactly 60 branches of science. Science is a vast and interconnected field with many overlapping areas of study. It's more accurate to think of science in terms of broader categories and subfields within those categories.

Here's a breakdown of some major categories of science and examples of subfields:

Natural Sciences:

* Biology: Zoology, Botany, Microbiology, Genetics, Ecology, Evolution, Physiology

* Chemistry: Organic Chemistry, Inorganic Chemistry, Biochemistry, Analytical Chemistry, Physical Chemistry

* Physics: Classical Mechanics, Thermodynamics, Electromagnetism, Optics, Quantum Mechanics, Nuclear Physics, Astrophysics

* Earth Science: Geology, Meteorology, Oceanography, Climatology, Paleontology, Hydrology

Social Sciences:

* Psychology: Developmental Psychology, Cognitive Psychology, Social Psychology, Clinical Psychology
