Molecular physics focuses on multi-atomic structures and their inner and external interactions with matter and lightweight. Optical physics is distinct from optics in that it tends to focus not on the management of classical gentle fields by macroscopic objects however on the basic properties of optical fields and their interactions with matter in the microscopic realm. With the standard consensus that the laws of physics are common and don’t change with time, physics can be utilized to review things that would ordinarily be mired in uncertainty...

Hawking referred to himself as an “unashamed reductionist” and took problem with Penrose’s views. According to Asger Aaboe, the origins of Western astronomy can be found in Mesopotamia, and all Western efforts in the precise sciences are descended from late Babylonian astronomy. Early civilizations dating again earlier than 3000 BCE, such as the Sumerians, historical Egyptians, and the Indus Valley Civilisation, had a predictive data and a primary understanding of the motions of the Sun, Moon, and stars. The stars and planets, believed to characterize gods, were usually worshipped. But when the first pendulum clock was brought to the Americas, one thing bizarre occurred.

Physics is a quantitative science because it is based mostly on measuring with numbers...
