Earth
Earth is the third planet from the Sun and the only object in the Universe known to harbor life. According to radiometric dating and other sources of evidence, Earth formed over 4.5 billion years ago. Earth's gravity interacts with other objects in space, especially the Sun and the Moon, Earth's only natural satellite. Earth revolves around the Sun in 365.26 days, a period known as an Earth year. During this time, Earth rotates about its axis about 366.26 times.
Engineering
Engineering is the creative application of science, mathematical methods, and empirical evidence to the innovation, design, construction, operation and maintenance of structures, machines, materials, devices, systems, processes, and organizations. The discipline of engineering encompasses a broad range of more specialized fields of engineering, each with a more specific emphasis on particular areas of applied mathematics, applied science, and types of application. See glossary of engineering.
Physics
Physics (from Ancient Greek: φυσική (ἐπιστήμη), translit. physikḗ (epistḗmē), lit. 'knowledge of nature', from φύσις phýsis "nature") is the natural science that studies matter and its motion and behavior through space and time and that studies the related entities of energy and force. Physics is one of the most fundamental scientific disciplines, and its main goal is to understand how the universe behaves.
Space
Space is the boundless three-dimensional extent in which objects and events have relative position and direction. Physical space is often conceived in three linear dimensions, although modern physicists usually consider it, with time, to be part of a boundless four-dimensional continuum known as spacetime. The concept of space is considered to be of fundamental importance to an understanding of the physical universe. However, disagreement continues between philosophers over whether it is itself an entity, a relationship between entities, or part of a conceptual framework.

I experience the same sense of absurdity when I listen to a cosmologist like Stephen Hawking telling us that the universe began with a big bang fifteen billion years ago, and that physics will shortly create a 'theory of everything' that will answer every possible question about our universe; this entails the corollary that God is an unnecessary hypothesis. Then I think of the day when I suddenly realized that I did not know where space ended, and it becomes obvious that Hawking is also burying his head in the sand. God may be an unnecessary hypothesis for all I know, and I do not have the least objection to Hawking dispensing with him, but until we can understand why there is existence rather than nonexistence, then we simply have no right to make such statements. It is unscientific. The same applies to the biologist Richard Dawkins, with his belief that strict Darwinism can explain everything, and that life is an accidental product of matter. I feel that he is trying to answer the ultimate question by pretending it does not exist.
Colin Wilson in Alien Dawn, pp. 301-302
Physics
As soon as we venture on the paths of the physicist, we learn to weigh and measure, to deal with time and space and mass and their related concepts, and to find more and more our knowledge expressed and our needs satisfied through the concept of number, as in the dreams of Plato and Pythagoras.
D'Arcy Wentworth Thompson, On Growth and Form (1917)
Earth
And again, observe ye the days of summer how the sun is above the earth over against it. And you seek shade and shelter by reason of the heat of the sun, and the earth also burns with growing heat, and so you cannot tread on the earth, or on a rock by reason of its heat.
Book of Enoch, Chapter 4, translated by Robert Charles, 1917.
