" Middle World ", a term coined by evolutionary biologist Richard Dawkins, is used to describe the realm generally experienced by humans that lies between the microscopic world of quarks and atoms and the cosmic world of stars and galaxies. It also refers to the lack of appreciation humans generally have for the spectrum of time, from picoseconds to billions of years, because people generally refer to time in units of minutes or hours or weeks and live for only a portion of a century. This term is used as an explanation of oddity at both extreme levels of existence. We have a lack of understanding of the quantum and molecular parts of the universe, because the human mind has evolved to understand best that which it routinely encounters.
